The Fall can be a great time to get outside and work on eradicating
non-native invasive plants. Several
woody invasive plants are particularly vulnerable at this time of year, and
into the winter months as well. Some of
these species include the shrubs, Amur honeysuckle (<i>Lonicera maackii</i>), autumn olive (<i>Eleagnus umbellate</i>), and burning bush (<i>Euonymous alatus</i>). Non-native
invasive trees that can be treated this time of year include tree-of-heaven (<i>Ailanthus altissima</i>), mimosa (<i>Albizia julibrissin</i>), Amur cork tree (<i>Phellodendron amurense</i>), and callery
(Bradford) pear (<i>Pyrus calleryana</i>), as
well as the non-native invasive woody vines like Japanese honeysuckle (<i>Lonicera japonica</i>), Oriental bittersweet
(<i>Celastrus orbiculatus</i>), and winter
creeper (<i>Euonymus fortunei</i>).<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Cut-stump and basal bark applications can be used to target
non-native invasive woody species year-round.
Another option this time of year can be a foliar application to the
leaves of woody invasive plants. Many
desirable native species go dormant before the non-native invasive species,
especially the semi-evergreen Japanese honeysuckle and winter creeper. Executing a foliar application at this time
of year can avoid non-target impacts. Remember
that cutting without using an herbicide will likely lead to the woody plant re-sprouting,
often with greater vigor, next growing season.
In addition, care should be taken with two of the aforementioned
species. Tree-of-heaven and Oriental bittersweet have a defensive mechanism
that is not to be taken lightly. Once
cut, or injured, the plants of those two species will send up sprouts from
nodes on their roots that will make an infestation worse, so the preferred
treatment method for those species is a basal bark application. <o:p></o:p></div>

A recent field day at Southern Illinois University's Belleville Research Station taught growers how to recognize the plant if they see it in their fields. See the information below with a link to the full article from <i>Illinois Farmer Today</i>.<br />
<br />
<i>"Achyranthes japonica</i>, or Japanese chaff flower, is a relatively
new invasive species that is plaguing the Ohio River Valley. This
species is a relative to some prominent agriculture weeds and grows in
both forested areas and along agriculture field
margins. Thus, all land owners/managers should be aware of this rapidly
spreading species and know how to identify and control it. Southern
Illinois University, the only university conducting research on this
species in the U.S., did this at their annual Belleville
Research Field Day in July. Over 150 people attended the field day
where they learned, in part, about Japanese chaff flower and its threat
to their properties. Some of the threats posed by this species is that
it has continual germination throughout the growing
season, it is a perennial species, and it can spread rapidly by a
variety of vectors. Also, Japanese chaff flower has about a 97 percent
germination rate; whereas other weed species in the family have about a
14 percent germination rate. With help from field
days like this, information about Japanese chaff flower, and other
invasive species, reaches the public in a positive way. Please do not
hesitate to report any sightings of Japanese chaff flower. " --Lauren Schwartz<br />

Japanese chaff flower, is a relatively new exotic species found in southern
Illinois. Japanese chaff flower is native to eastern and southeastern Asia, but
was first found in the United States in 1981 along the Tug Fork River, a
tributary of the Big Sandy River in Martin County, Kentucky. It is unknown how
this species was first introduced to the United States, but it is believed to
coincide with railroad traffic. This invasive species has quickly spread along
the Ohio River and its tributaries. Today, Japanese chaff flower can be found
in every county along the Ohio River from West Virginia to Illinois, and has
been confirmed in Missouri along the Mississippi River in 2011. It is currently
found in nine states (West Virginia, Kentucky, Ohio, Indiana, Illinois,
Missouri, Tennessee, Alabama, and Georgia).</span></div>

chaff flower is a perennial and herbaceous species that is easy to identify. It
has been determined that this species becomes perennial at an early growth
stage, by the time it reaches three nodes. Japanese chaff flower’s leaves are
opposite and simple. The stem at ground level is red, which is seen in other
pigweed species. The flowers occur on erect spikes at the end of the stems and
upper branches. The flowers, which lack petals, occur in tight clusters and
diverge at nearly a right angle, which gives the flowers a bottle-brush look.
As the fruits mature, the spikes elongate and the fruits lay flat against the
spike. </span></div>

that help in dispersal. Japanese chaff flower primarily disperses its seeds in
water during heavy floods or by attaching to clothing, shoes, hair, or animal
fur. “Becoming entangled or ‘hitch-hiking’ is a dispersal mechanism associated
with Japanese chaff flower seed,” said Travis Neal, a master’s student at
Southern Illinois University, Carbondale. “Its dispersal is enhanced during
particular life stages, which enables Japanese chaff flower to readily invade
native plant communities of southern Illinois as well as the surrounding Ohio
and Mississippi River Valleys.” Japanese chaff flower can be found growing in
areas with partial sun and moist soils, but can also grow in heavily shaded and
dry area. Populations of this species have been found in bottomland forests,
along riverbanks, along agriculture field margins, and in roadside ditches.</span></div>

chaff flower starts growing in late spring and flowers in the late summer.
Flowers can continue to develop into the early fall, even when seed is starting

turn an orange-brown color. The dead plant stand can remain erect even into the
winter until heavy snow, ice, or floods cause the stems to break. The high
germination rate (~ 62% in drought years and ~94% in average years) and the
high seed output (up to 1,000/plant) of this species make it a strong
competitor for the following year. It has similar competitive capabilities of other

spread for this species. After any activities (i.e. hiking, camping, hunting,
fishing) in an infested area, you should make sure to thoroughly clean
clothing, boots, equipment, and pets to help prevent any further spread
especially in the fall when seeds are mature. Although little is known about
the management of this invasive species, initial treatments of triclopyr at a
2% solution appeared to be most effective. Other herbicides, such as
glyphosate, aminopyralid and 2,4-D ester, are also effective at higher doses.
The perennial plants of this species are highly susceptible to foliar
applications of broad leaf systemic herbicides, which makes them a good
management tool in the field. Hand pulling or digging large, mature stands is
not feasible due to the extensive root systems. If you find Japanese chaff
flower in Illinois, please report the location to Karla Gage at <a href="mailto:rivertoriver@gmail.com"><span style="color: blue;">rtrcwma@gmail.com</span></a>.</span></div>

<![endif]--><span style="font-family: "Arial","sans-serif";">On Friday, May 9th, 2014, as the opening ceremony to the Cache River Nature Fest and as a celebration of the Governor’s proclamation of May as Invasive Species Awareness Month, a Regional Awards Ceremony was hosted by Shawnee Resource Conservation and Development Area, Inc. (RC&D) and the River to River Cooperative Weed Management Area (CWMA), in order to recognize 15 individuals highly dedicated to invasive plant species control work in Southern Illinois. These individuals recognize that one of the biggest challenges facing conservation today is the widespread problem of non-native invasive species, which destroy habitat for native plants and animals. The award recipients have all taken their knowledge of invasive species one step further, acting with responsibility to create a positive impact on the diversity of habitats in Southern Illinois. Several CWMA partnering organizations and Steering Committee members were present to support the recipients and their work. The award recipients and their contributions are as follows:<br /><br /><b>Illinois Invasive Species Strike Team work: Tharran Hobson (TNC), Caleb Grantham (TNC), Nick Seaton (TNC), Bob Lindsay (IDNR) </b>– Tharran is the River Program Restoration Manager for The Nature Conservancy’s Illinois River Program, and the program manager for our local Southern Illinois Invasive Species Strike Team, a role in which he helps to direct critical conservation efforts in the region. He was nominated for his persistence in pursuing the implementation of the Strike Team grant funding. Without Tharran’s efforts, the Strike Team contract would not have been processed, and the team would not have been hired. Strike Team members Caleb Grantham and Nick Seaton were recognized for their spring 2014 work. By mid-April, they had assisted with 1,787 acres of prescribed burning on high quality sites in Southern Illinois, including conservation work to protect a state endangered plant population. Caleb and Nick are graduates of the Southern Illinois University Carbondale (SIUC) Department of Forestry B.S. program. Caleb and Nick controlled invasive plants with IDNR as 2013 summer interns, directed by Heritage Biologist, Bob Lindsay. Bob has continued to be a critical mentor for the Strike Team, and he was responsible for continuing invasive species control on more than 8 critical sites, during the 2013 lapse in funding for the Strike Team. <br /><br /><b>Shawnee National Forest’s Invasive Species Management Environmental Assessment - Richard Blume-Weaver (USFS) </b>– Richard was instrumental in keeping the Forest’s Invasive Species Management Environmental Assessment on track and moving forward. This management decision allows the Forest to actively treat invasive species on about 1800 acres across Southern Illinois. The plan focuses on controlling four of our priority invasive species (kudzu, bush honeysuckle, Chinese yam and garlic mustard). An additional focus area is the control of invasive species in 23 natural areas that are in need of protection. Richard’s dedication and persistence to the management of invasive species on the Shawnee National Forest and Southern Illinois are an asset to the entire region. <br /><br /><b>Unity Point School Invasive Species Education: Chris Midden</b> – Chris teaches science at Unity Point School in Makanda, Illinois. He has developed a unit on invasive species, which he covers while teaching ecology, and he takes his entire 6th grade class of students into the field at the Green Earth, Inc. (GE) Chautauqua Bottoms site, to pull garlic mustard and learn first-hand about the effects of invasive species on native biodiversity. This GE site is known for a diverse population of native spring ephemeral species, and is the opportune place to teach hands-on lessons of the impacts of invasions. We would like to thank Chris and Unity Point and all the 6th grade students for this valuable contribution to Invasive Species Education, as well as the positive impact on garlic mustard control at this biodiverse site in Carbondale. <br /><br /><b>Volunteer Public Education Efforts: Dr. Andrew West </b>– Dr. West was recognized for extensive involvement in numerous volunteer work days, public presentations and workshops, and for leading hikes for the public to discuss native biodiversity and the impacts of invasive species on the region of Southern Illinois. He has worked for almost 40 years as a land and natural resource manager, 30 years with IDNR and brief stints with the U.S. Forest Service, Fish and Wildlife Service, and Missouri Dept. of Conservation. He was site superintendent at Trail of Tears State Forest for 15 of his 30 years with the State of Illinois. He continues to use his knowledge to assist landowners with invasive species control in Southern Illinois, and our regional efforts in Invasive species control are strengthened through his work.<br /><br /><b>Volunteer Control Work with Green Earth, Inc.: Mike Long and Chris Long </b>– Mike and Chris have been long-time supporters of Green Earth, Inc. (GE) in Carbondale, IL. GE provides an important function to Carbondale residents, by preserving green spaces within an urban environment, which make nature accessible to people of all backgrounds and promoting environmental education. The efforts of GE began with the purchase of a 20 acre piece of land over 25 years ago, and now they manage over 190 acres on 6 tracts of land. GE is a non-profit and depends on monetary donations and volunteer efforts to manage their properties. Unfortunately, as natural habitat-urban interfaces, these properties are often plagued by a variety of invasive issues. Mike and Chris have stepped in to fill the need for invasive species control at some GE sites. They have adopted GE sites for control, have written a management plan for invasives control, and have paid their employees out-of-pocket to manage invasive plants at these properties. We thank them for their efforts, for providing this service, and therefore, helping to raise awareness about the issue of invasive species in Carbondale.<br /><br /><b>Regional Volunteer Invasive Species Control and Outreach: Bruce Henry</b> - As Rx fire coordinator and crew manager for the Saluki Fire Dawgs, SIUC’s prescribed fire team, Bruce helps facilitate burns on state and private lands, encouraging the promotion of healthy forest ecosystems and the control of invasive species in Southern Illinois. Bruce assists with GE volunteer workdays as a volunteer and member of the Omega Chapter- Xi Sigma Pi, Honors Society. Bruce serves as a mentor, sharing his vast knowledge of invasive species control and native plant ID with current Strike Team members, undergraduate students and peers. He has provided outreach and oversight to a number of garlic mustard "pull-events" with the Sierra Club and local schools, and he has led native plant hikes through Natural Areas in the Cache River Wetlands for local school groups. He has provided landowners with invasive species control and identification information on his own and through NRCS funded programs. He volunteered time to travel to Northern Illinois to train the Northern Illinois Strike Team in Jo Davies County. Bruce is the caretaker of the field house at Cypress Creek National Wildlife Refuge and provides invasive species control on site. Additionally, Bruce has recently been awarded the position of natural history biologist with the Missouri Department of Conservation for the Southeastern region of Missouri. <br /><br /><b>Landowner Support and Education through NRCS Programs: Ryan Pankau (NRCS Conservation Forester)</b> – Ryan and the Natural Resources Conservation Service (NRCS) have been critical supporters and partners in CWMA efforts to control invasive species. Private landowners own 82% of the forested land in Illinois, and it can be difficult to reach these diverse groups and individuals with technical assistance. Ryan continues to help with this effort in Southern Illinois, providing invaluable support to landowners. He speaks about NRCS assistance programs whenever the opportunity arises and has helped with organization and implementation of several workshops and trainings for landowners in the identification and control of invasive species. He has provided much needed assistance in conservation issues in Southern Illinois by reaching out to landowners and going above and beyond what is expected as NRCS Conservation Forester. <br /><br /><b>Regional Training of Natural Resources Professionals and Volunteers: Sonja Lallemand</b> - Sonja is being recognized for creating and implementing very successful programming that is becoming an established standard within the regional conservation community. The Master Naturalist training that Sonja has brought to Southern Illinois is a highly sought-after program with many more individuals wanting the training than the program can accommodate. To date, this University of Illinois Extension program has graduated approximately 60 students trained for conservation work. Through training these passionate individuals, Sonja is creating an invaluable resource for all conservation partners, and she is always looking for new ways to engage her students in invasive species issues. <br /><br /><b>Carbondale Park District Support in Invasive Species Outreach to the Public: Kathy Renfro </b>– Kathy has been instrumental in developing the partnerships and on-the-ground work for the pilot project of the Illinois Stop the Spread! program. Illinois Stop the Spread! is focused on educating consumers about the invasiveness and other undesirable characteristics of the Callery (Bradford) pear. The program is in the preliminary stages, but there is a large education and outreach component, with a positive message, which offers consumers and others a list of locally-available alternatives to Callery pear. A demonstration planting of these native tree alternatives has recently been established at Attuck’s Park in Carbondale with Kathy’s and Grounds Manager Randy Montgomery’s help. Kathy’s and Carbondale Park District’s involvement in this campaign has been key in raising awareness of the issues surrounding Callery pear.<br /><br /><b>Invasive Species Control on Private Lands: Gary and Sharon Swisher</b> - Gary and Sharon have earned this recognition for invasive species control efforts on their own property (~275 forested acres). They are very active at controlling invasives and consistently conducting monitoring and follow-up treatments. They truly understand what is needed to effectively control invasives species. As landowners, they benefit from controlling invasives, their children benefit from a healthy future forest and their neighbors benefit from a reduced seed source in the community. Gary has worked at controlling invasives on his neighbor’s property and has been an influential example of success. By contributing to the reduction of invasive populations in Jackson County and by influencing neighboring landowners to do the same, the Swishers have truly exemplified excellence in addressing invasive species.<br /><br /><b>Recognition of Legislative Support in Invasive Species Issues: State Representative Brandon Phelps</b> – Rep. Phelps was the chief sponsor of the Bill to amend the Illinois Exotic Weed Act by adding kudzu and six non-native varieties of buckthorn. This was the first bill Rep. Phelps served as a sponsor, during his freshman year as a legislator. These additions to the exotic weed list were very significant. Through this law, it became illegal to buy, sell or plant these plants in Illinois. Buckthorn has created extensive damage to thousands of acres in northern Illinois and anyone who has traveled to the southern United States has seen the overwhelming impact of kudzu. While this bill became law ten years ago, it was the last time the Illinois Weed Act was amended, creating a statewide impact. We recognize Rep. Phelps for his important legislative contribution. <br /><br />The RC&D, CWMA, and all partners truly appreciate the efforts and successes of these individuals to further our regional invasive species control efforts.</span><br />

Management Area (CWMA) to remove invasive burning bush or fire shrub from the

<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-fareast-font-family: "Times New Roman";">Dixon Springs Agricultural Center
(DSAC), established in 1934 on 5,100 acres of un-glaciated land, is special
place nestled within the Shawnee National Forest (NF) - dedicated to agronomic
research that connects land managers in Southern Illinois to research
priorities of the University of Illinois College of ACES and Veterinary
Medicine. The DSAC facility sits directly adjacent to the Shawnee NF
within an area of Illinois designated as a Conservation Opportunity Area (COA)
by the Illinois Wildlife Action Plan. There are three COA’s in the
southernmost 11 counties of Illinois. These COA’s are areas where there
are important wildlife and habitat resources, coupled with the potential
networks and organizations to conserve these resources. One of the most
important aspects of conserving wildlife and habitat resources is the
management of invasive species.</span></div>

<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-fareast-font-family: "Times New Roman";">Burning bush has been prohibited
from sale in three states (Massachusetts, Connecticut, and New Hampshire)
because of its invasive potential. Invasion of burning bush, like other
woody invasive species, may out-compete native forest understory plants and
cause decreased biodiversity in forests. Invasive burning bush can be
found in Southern Illinois, in forested land surrounding homes or neighborhoods
with ornamental plantings. It is estimated that burning bush has been in
landscaping around the DSAC buildings for fifty years, and now hundreds of
plants can be found in the forest understory. Recognizing the problem,
Jim Kirkland, director of the Forest Resource Center, decided to plan a
Woodland Restoration Event in coordination with the River to River CWMA to
preserve the natural resources around the DSAC. </span></div>

<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-fareast-font-family: "Times New Roman";">On Saturday, November 2<sup>nd</sup>,
2013, volunteers gathered in the DSAC dormitory basement to learn how to
identify burning bush and three other woody invasive species – bush
honeysuckle, autumn olive, and multiflora rose. Individuals represented
all skill levels in land management, and were taught all the techniques
necessary for invasive species control. Several groups were represented,
including the Southeastern Illinois Prescribed Burn Association (SIPBA),
Illinois Forestry Association, University of Illinois Master Gardeners and
Master Naturalists, Southern Illinois University Department of Forestry and
Society of American Foresters Student Chapter, and Smith Tree Farm LLC.
Volunteers with chainsaws, hand saws, and loppers cut the woody plants at 6
inches or less from the ground surface. Then certified pesticide
applicators applied a 25% solution of glyphosate in water, mixed with blue dye
so that it was easy to track the cut surfaces that had been treated. Cut
surfaces were treated within 10 minutes or less to ensure the root system takes
up the herbicide. Since seeds were present, the plants were left in the
location where they were cut. Dragging the plants to another location
would have spread the seeds and contributed to the invasive problem in the
future. It is estimated that volunteers were able to control invasive
species on approximately 2 acres of DSAC land, mostly focusing on the edges of
the woodland, since that is where mature plants were producing the most
seed. </span></div>

Species to Watch: Winged Burning Bush</span></b></span></div>
<div align="center" class="MsoNormal" style="text-align: center;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Georgia,"Times New Roman",serif;"><span style="font-size: small;">That’s
invasive!? Winged burning bush (<i>Euonymus
alatus</i>) is a favored plant in landscaping, and many people
are unaware of its aggressive, invasive tendencies once the seeds are dispersed
by birds. There are many cultivars of burning bush - loved for its brilliant
red fall foliage and its ability to be pruned and shaped into almost any form. Burning
bush is hardy up to zone 4, and grows in almost any soil conditions except
continually moist soils - one of the reasons it is often overused in the
landscape. However, there is a dark side to this horticultural favorite - so
dark that it is now banned for sale and propagation in Connecticut, Massachusetts,
and New Hampshire. In a study on its invasiveness, cultivars had an estimated
seed production that ranged from 588 to 3763 seeds per plant, and 40% of seeds
could produce new plants. Therefore, each year, it is conservatively estimated
that one burning bush on private property may be sending more than 235 young
plants into adjacent land. These new seedlings have the potential to form dense
thickets and displace the local native plant species.</span></span></div>

<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Georgia,"Times New Roman",serif;"><span style="font-size: small;">It is easily distinguished from native and other
invasive look-alikes by the greyish-brown, corky, winged structures on the
young green stems. Leaves are about 2 inches long, elliptical with a pointed
tip, finely toothed along edges, and oppositely paired along the stem. Small flowers
with four yellowish-green petals appear in May. Green fruits mature throughout
the summer. In the fall, the outside fruit capsules turn red to brownish-purple
and split to reveal fleshy, red arils, which birds disperse. Depending on the
cultivar, plants may reach heights of 12 feet tall or more. Unfortunately,
burning bush is becoming a common sight in the forests of southern Illinois and
is no longer recommended for planting by conscientious land managers. Although a sterile cultivar of burning bush
has been developed, there are several native alternatives, which offer very
attractive replacements in landscaping, such as red chokeberry (<i>Aronia arbutifolia</i>), large fothergilla (<i>Fothergilla major</i>), Virginia sweetspire
(<i>Itea virginica</i>), Blackhaw (<i>Viburn prunifolium</i>), shining sumac (<i>Rhus copallinum</i>), and Eastern wahoo (<i>Euonymus atropurpureus</i>).</span></span></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Georgia,"Times New Roman",serif;"><br /></span></div>
<span style="font-family: Georgia,"Times New Roman",serif;"><span style="font-size: small;">
</span></span><br />
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: Georgia,"Times New Roman",serif;"><span style="font-size: small;">There
are several ways to control burning bush. Small seedlings can be hand-pulled. Shrubs
can be cut and treated with a systemic herbicide, such as glyphosate or
triclopyr. Cut surfaces should be treated with herbicide in less than 10
minutes following cutting, so that the cut surface does not dry and prevent
herbicide uptake. A basal bark application of herbicide (triclopyr in oil) may
also be used if cutting the plant is not desirable. A foliar herbicide
application may be used at a low rate (2 – 4%) for small plants. Always follow
label instructions when applying herbicides and wear the appropriate protective
gear. </span></span></div>

<span style="font-family: Georgia,"Times New Roman",serif;"><span style="font-size: small;">Please
help encourage others to landscape with native or non-invasive species. If you
find escaped burning bush in Illinois natural areas, please report these
sightings by visiting EDDMaps at the River to River CWMA website
(http://www.rtrcwma.org/report). Please

<b style="font-size: 11pt;"><span style="font-family: Garamond, serif; font-size: 12pt;">Ann Arbor, Mich.</span></b><b style="font-size: 11pt;"><span style="font-family: Garamond, serif; font-size: 12pt;"> –</span></b><span style="font-family: Garamond, serif; font-size: 12pt;">The rapid spread of the invasive plant <i>Phragmites australis </i>(also known as common reed) in wetlands and roadside ditches across the Great Lakes has sparked intensive management and planning efforts to stem the tide of the plant’s progression. To augment these efforts, a new interactive mapping and communication tool,<a href="http://greatlakesphragmites.net/programs-and-projects" style="color: #1155cc;" target="_blank">greatlakesphragmites.net/<wbr></wbr>programs-and-projects</a>, is highlighting invasive <i>Phragmite</i>s management initiatives taking place across the region.</span></div>

<span style="font-family: Garamond, serif; font-size: 12pt;">“Phragmites management is an expensive, time consuming and long-term endeavor,” Braun says. “In order to be efficient with our limited financial resources and make the greatest long-term impact, we need to learn from each other and build on our collective success.”<u></u><u></u></span></div>

<span style="font-family: Garamond, serif; font-size: 12pt;">A diverse group of stakeholders – including private landowners, lake associations, road commissions, state and federal agencies, and private conservation organizations – are leading <i>Phragmites</i> management and research efforts. Many have developed strategies that have proven successful (or unsuccessful) and could be used to help jumpstart new initiatives; however much of the focus to date has been on management – not communication. The new webpage provides a forum to both share information and learn from others engaged in <i>Phragmites</i> management throughout the Great Lakes region.<u></u><u></u></span></div>

<span style="font-family: Garamond, serif; font-size: 12pt;">The site features an interactive map with points and polygons representing the location and scope of ongoing <i>Phragmites</i>projects and programs. Those engaged in <i>Phragmites</i> management are urged to contribute to the webpage by entering information on their projects. Photos and other media can be uploaded to help managers demonstrate their work. Information on education and outreach programs, mapping and monitoring, policies, ordinances and administrative partnerships, such as Cooperative Weed Management Areas, is also encouraged.<u></u><u></u></span></div>

The River to River CWMA has updated its map of known locations for Japanese chaff flower. Currently, chaff flower is found in 9 counties in southern Illinois, mostly along the Ohio and Cache Rivers. The CWMA is planning further survey efforts for this summer and fall to look for new infestations as well. To learn more about Japanese chaff flower, read the 2011 Wildland Weeds article by Evans and Taylor at <a href="http://www.rtrcwma.org/chaffflower2011.pdf">http://www.rtrcwma.org/chaffflower2011.pdf</a></div>River to River CWMAhttp://www.blogger.com/profile/02065828332131419099noreply@blogger.comtag:blogger.com,1999:blog-5734673609827065677.post-42526422110303787482012-06-18T06:28:00.002-07:002012-06-21T13:40:34.420-07:00Be on the Lookout - Teasel<table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: right; margin-left: 1em; text-align: right;"><tbody>

<em>Occasionally, we will place a post up on this blog about a particular invasive species. These 'Be on the Lookout' posts are timed to when the target species is most visible and easily identified. Today's post is on Teasel.</em></div>
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
<br /></div>
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
Southern Illinois is home to two species of exotic teasels. Common teasel (<em>Dipsacus fullonum</em>) and cutleaf teasel (<em>D. laciniatus</em>). Both teasel species can be found in grasslands, pasture, and roadsides. These thistle-like species are very spiny and can form dense stands if left uncontrolled. </div>
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
<br /></div>
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
Early summer is the perfect time of year to identify teasel as the second-year plants are starting to flower. Teasel is a biennial plant, with first-year plants being small rosettes and a large flowering stalk on the second-year plants. Look for purple (common) or white (cutleaf) flowers on a 3-7 feet tall flowering stalks. The flower-heads are very unique, looking like a spiny dome with rings of small flowers along the outside and long bracts surrounding it. </div>

Some invasive species are more recognizable at certain times of the year and the success of control techniques often depend upon the right timing. The River to River CWMA is creating a series of article about invasive species in the different seasons. Be sure to also read </span><a href="http://rtrcwma.blogspot.com/2011/09/fall-is-time-to-identify-many-woody.html" target="_blank"><span style="font-size: x-small;">THIS</span></a><span style="font-size: x-small;"> article on </span><a href="http://rtrcwma.blogspot.com/2011/09/fall-is-time-to-identify-many-woody.html" target="_blank"><span style="font-size: x-small;">invasive species in fall</span></a><span style="font-size: x-small;">.</span></em><br />
<br />
You’ve spent all spring pulling garlic mustard and are gearing up for your fall and winter treatments of woody invasive plants. But what should you be doing with invasive plants during the summer?<br />
<br />
<br />
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
It is tempting to stay indoors and avoid the heat, ticks, and chiggers that come with summer, but this time of year is ideal for controlling several invasive species. Herbaceous plants, such as Japanese stiltgrass and teasel are good targets for those warm summer months. Both of these species flower and set seed in the summer and then die (stiltgrass is an annual and teasel is a biennial). To effectively control infestations, you need to eliminate seed production; which means controlling them in the summer. Control teasel by spraying the rosettes or young bolting plants in early summer or hand-pulling the flowering plants in midsummer. For Japanese stiltgrass, wait until mid-summer to spray infestations. You can mow, hand-pull, or weed-whip infestations of stiltgrass anytime in the summer before flowering. Be sure to revisit control areas to follow up and retreat any new growth. </div>

<br /></div>
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
Johnsongrass and Chinese yam are both best targeted in summer. While these two are both perennial plants, they are most vulnerable in the summer months. Look to treat Johnsongrass in early summer, just before it flowers. Chinese yam is best controlled in June, before the aerial tubers (bulbils) are formed.</div>
<br />
Good information, including control recommendations for these and other species, can be found on the River to River CWMA Species of Concern page: <a href="http://www.rtrcwma.org/species.html">http://www.rtrcwma.org/species.html</a><br />
<br />
Working the summer comes with its own set of safety risks. Overheating and dehydration are real possibilities. Be sure to take plenty of breaks and drink lots of water when working on hot days. Also, it is a good idea to avoid working alone during the summer. Having someone else with you can ensure speedy treatment if necessary.<br />
<br />
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
Another factor to consider when working in the summer is the impacts heat can have on herbicides. Excessive heat can increase the ability of herbicides to volatize, where the herbicide turns to vapor and can drift away. This can be a serious problem. The loss of the active ingredients from the herbicide mixture due to volatilization can drastically reduce its effectiveness. Additionally, those vapor pockets that form can drift over and damage non-target plants. You can reduce the risk of excessive volatilization by not using ester-based herbicides when the temperatures are over 90°F. </div>
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">
<br /></div>
Summer is a great time of year to get out and control certain invasive species. Using the proper precautions will keep your treatments effective and you safe. Lastly, don’t forget to find time between all of your summer invasive plant treatments to set aside at least a few days to go fishing and camping!<br />

The Midwest Invasive Plant Network, In cooperation with the University of Wisconsin-Madison, has recently published a great resource for landowners, land managers, and anyone that manages invasive plant species in the Midwest. This new online database can be found at: <a href="http://mipncontroldatabase.wisc.edu/">http://mipncontroldatabase.wisc.edu/</a> and allows the user to search for chemical and non-chemical control methods for common invasive species in the Midwest. All recommendations were reviewed by experts and ranked as to their effectiveness. Users can also refine the recommendation results based upon expertise level, habitat type, and season. This is a great new tool that will provide up-to-date control information for maximizing the effectiveness of your management efforts.River to River CWMAhttp://www.blogger.com/profile/02065828332131419099noreply@blogger.comtag:blogger.com,1999:blog-5734673609827065677.post-58787063026965251412012-05-21T13:12:00.001-07:002012-06-21T13:50:13.475-07:00Start looking for Japanese Stiltgrass <br />

Now that garlic mustard season is slowing down and turkey and morel hunting has came to an end, it is time for landowners to start looking for Japanese stiltgrass. This relatively new species may not be on many landowner's radar yet. While it has been in southern Illinois since the late 1960s, only in the last 15 or so years has it really started to spread wide. The recent ice and wind storms we've had is only helping this plant take hold in our forests.<br />
<br />
Japanese stiltgrass is a serious invader of bottomland and other moist woodlands but can also grow in drier areas. Keep an eye out for this plant starting to invade along roads, trails, deer paths, streamsides, and fire breaks. This is an annual plant that produces a lot of seed, so it is important to find and control it before it flowers and reproduces for the year (usually late August to early September). <br />
<br />
Look for patches of a wiry grass with short, wide leaves. More information on Japanse stiltgrass, including identification tips and control recommendations can be found on the River to River CWMA's 'Species of Concern' page: <a href="http://www.rtrcwma.org/species.html">http://www.rtrcwma.org/species.html</a>.<br />

It has mostly been restricted to forestlands ajacent to the Ohio River, but several recent finds indicate that it is moving inland. Just last week, three different infestations were found in Johnson County on state lands. These new locations may have been started by hikers unintentionally moving seeds around.<br />
<br />
Because chaff flower seeds can readily stick to clothing, hair, and animal fur, it is important that anyone hiking, hunting, or otherwise being in the forests in southern Illinois take the time to clean off and remove seeds from their clothing and mud and dirt from their shoes before and after going into the woods. This simple step can have a real impact on slowing the spread of invasive plants.<br />
<br />

In this article, the researchers were looking at bush honeysuckle and how invasions lead to a decrease in amphibian diversity (both richness and eveness). Basically what happened was the slightly cooler temperatures under the honeysuckle lead to the native green frog flourishing, which it then was able to outcompete the other native amphibians, leading to domianance by one species and lower diversity overall. You can find their research in <a href="http://www.sciencedirect.com/science/article/pii/S0006320711002588">Biological Conservation</a>.<br /><br />The second story came from NPR's 'Living on Earth' series and it was about invasive plants in Montana's grasslands. The stiff thatch of the invaders, such as spotted knapweed and leafy spurge, has provided structure for a couple of native spiders to build more and larger webs than they would be able to in native prairie. This has led to more insect prey being caught, allowing the spiders to reproduce more and thus build more webs and feed on more insects. They sum up their point very well by saying "The native spiders are thriving because of the new exotic plants. They can eat more insects, and these insects can then no longer keep the growth of certain plants in check, and on and on. You alter one piece of the ecosystem, and the whole web changes." You can read the transcript or listen to the audio of the story on the <a href="http://www.loe.org/shows/segments.html?programID=11-P13-00039&segmentID=6">Living on Earth website .<br /></a><br />Both of these stories really do illustrate a point that is often overlooked when considering invasive plants. Their presence in a new environment can have impacts that are unforseen and not restricted to direct competitors. With a cursory glance, one might even think these invaders are having a positive impact on their surroundings (both situations lead to an increase in the populations of native species), but a closer look reveals their ability to throw things out of balance and faciliitate a larger-scale collapse in diversity. I think the authors of the honeysuckle article put it best when they labelled honeysuckle as having the ability to be an "Invasive Ecosystem Engineer", which they describe in the below excerpt:<br />"Invasive species can have far-reaching impacts on ecosystems. Although some invasive species interact with native taxa primarily through one or few biotic or abiotic pathways (e.g., competition, allelopathy), habitat-forming invasive species may act as ecosystem engineers with the potential to affect many organisms through multiple different pathways. Although the impacts of invasive species are often framed in terms of trophic interactions between organisms (e.g., species that interact as competitors or as predators and prey), an emerging perspective emphasizes the ability of invasive plants to change habitat structure or quality, i.e., to act as ecosystem engineers. Invasive ecosystem engineers may have widespread effects on native species that do not directly consume or compete with the invader. Identifying these non-trophic effects is important because they may be pervasive, yet cryptic consequences of invasion, especially given the extensive realized and potential distribution of many species in invaded landscapes."River to River CWMAhttp://www.blogger.com/profile/02065828332131419099noreply@blogger.comtag:blogger.com,1999:blog-5734673609827065677.post-47935478613256020342011-09-26T08:19:00.000-07:002012-06-21T13:35:07.224-07:00Fall is the time to identify many woody invasive species<em><span style="font-size: x-small;">Invasive species and invasive species management change with the seasons.

<br />
With the arrival of autumn comes the changing of the colors of leaves and the ripening of fruits. Along with that, also comes the opportunity to easily find woody invasive plants. Many of these invasive species turn distinctive colors or stay green longer than native species, allowing for easy identification. Also, with the cooler temperatures, the disappearance of ticks and chiggers, and the senescence of posion ivy, it is a great time to be out in the woods.<br />
<br />
Here are some tips on what to look for when identifying some of our common woody invasive plants.<br />
<br />
<strong>Oriental bittersweet</strong><br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL3Wh0aefex9oN5hZ0tQ5N7J6BD13Y_Z7cwAHsCV400u6Et5UdFqoOxEkbabpAYg1MpkFBaf7fI0yZA-i-CXhr4ws5txEGKYmsjQaPejKzt4JK37sLAZnat96qrBj-ywUlrmkAWW35hV91/s1600/bittersweet.jpg"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5656695635848984690" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL3Wh0aefex9oN5hZ0tQ5N7J6BD13Y_Z7cwAHsCV400u6Et5UdFqoOxEkbabpAYg1MpkFBaf7fI0yZA-i-CXhr4ws5txEGKYmsjQaPejKzt4JK37sLAZnat96qrBj-ywUlrmkAWW35hV91/s200/bittersweet.jpg" style="cursor: hand; float: left; height: 200px; margin: 0px 2px 2px 0px; width: 134px;" /></a> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjBki1jKhvm3j8bWtLgcM0JtLdaHfHR3A8plvTPup9yjL-9rYEm77f4ZzxUHZcDiXyuqMMqoh6Lhm7B1EGxePP1TRbjoB1z4UtnLIt9i1yaSow6x-UYPtlax4dKeMc8gDIzgHgRjWmmT48u/s1600/bittersweet2.jpg"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5656695913588538370" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjBki1jKhvm3j8bWtLgcM0JtLdaHfHR3A8plvTPup9yjL-9rYEm77f4ZzxUHZcDiXyuqMMqoh6Lhm7B1EGxePP1TRbjoB1z4UtnLIt9i1yaSow6x-UYPtlax4dKeMc8gDIzgHgRjWmmT48u/s200/bittersweet2.jpg" style="cursor: hand; float: right; height: 152px; margin: 0px 0px 2px 2px; width: 200px;" /></a> Oriental bittersweet is a woody vine that climbs up and over trees and shrubs, particularly along forest edges. In the fall, bittersweet leaves turn a bright yellow color and the fruit on female plants mature and the covering splits open to reveal scarlet red berries (called arals). Look for the yellow leaves surrounding the trucks of trees or draping over the top of shrubs or lower branches of trees.<br />
<br />
<strong>Bush honeysuckle</strong><br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPLDoPKXpoRzU4p-_7vFQWa3Kq7G04CFDoPkYHpLMpOZ7h6cU-wEcck0ODlN5jeu3zU9OFDh4OKov_AcCmmLppP5T31UThN1PD2IffmjqmY9gSxSEkMiYFKKHxggBkjWKuLyzYyCM5CNvi/s1600/bush+honeysuckle.jpg"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5656697197591506130" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPLDoPKXpoRzU4p-_7vFQWa3Kq7G04CFDoPkYHpLMpOZ7h6cU-wEcck0ODlN5jeu3zU9OFDh4OKov_AcCmmLppP5T31UThN1PD2IffmjqmY9gSxSEkMiYFKKHxggBkjWKuLyzYyCM5CNvi/s200/bush+honeysuckle.jpg" style="cursor: hand; float: left; height: 200px; margin: 0px 2px 2px 0px; width: 138px;" /></a> Bush honeysuckle is a shrub that can be found growing along the edge or within the interior of a forest. Like bittersweet, it also has yellow leaves and bright red berries. Bush honeysuckle is unique in that it is often one of the last plants to remain green in the fall and one of the first plants to green up in the spring. In the fall, looking for honeysuckle shortly after the trees have lost their leaves is often the best time to spot this species. Look for small shrubs (10-15 feet tall) densely covered in leaves that are dark green turning to bright yellow.<br />
<br />
<strong>Burning bush</strong><br />
<img alt="" border="0" id="BLOGGER_PHOTO_ID_5656698394389818610" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6HyhVhjlKr6uXullLpHsiS9vyMi9Pq0rzXmkWw2yg3fCJvnJwtCa_cCSCPxPsLOMd8sAjdv1jdmBcpZCZxF3m3KPc7yloisMXr0jt9akYOI9ZazvKe9qC8lbaED1hYQDTnOx3RBbTB4Sp/s200/burning+bush.jpg" style="cursor: hand; float: right; height: 134px; margin: 0px 0px 2px 2px; width: 200px;" />Burning bush is a common ornamental shrub used in landscaping, but is starting to spread into wildlands in southern Illinois. This species is instantly recognizable in the fall by its bright red fall color and its upright growth form. Late in the fall, burning bush levaes turn from a dark green to a deep red in color. Often, during this turn, the leaves will have somewhat of a purplis or maroon tinge. Upon closer inspection, the branches will usually show some type of corky wings.<br />
<br />
<strong>Autumn olive</strong><br />

This species also keeps its leaves longer than most of our native species. When it still has its leaves, autumn olive can be recognized by the silvery coloration of the underside of the leaves. This coloration gives the entire plant a shiny, silverly sheen that stands out and separates it from any other shrub species.River to River CWMAhttp://www.blogger.com/profile/02065828332131419099noreply@blogger.com
