AOWCP installs billboard along the Ohio River

The Appalachian Ohio Weed Control Partnership along with Southern Indian Cooperative Invasives Management ( and River to River Cooperative Weed Management Area ( have continued working together to address invasive plant issues along the Ohio River.  Our partnership, Central Hardwoods Invasive Plant Network (CHIP-N) has partnered with the Ohio River Basin Fish Habitat Partnership and Wildlife Forever to install a billboard in Southern Ohio. We’ve had our billboard up along US 52 between Ashland, KY  and Southpoint, OH for over a month.  We should get anywhere from 800k-900k views over this time frame.  Hopefully efforts like this help people realize the importance of cleaning boating gear before traveling to another body of water.


Researcher looks for honeysuckle blight

A message from Dr. Richard L. Boyce:
As I noted last year about this time, this year I’m again seeing a lot of honeysuckle leaf blight on Amur honeysuckle (Lonicera maackii) in the Cincinnati area. One additional wrinkle is that I’m now seeing it in an area where I’ve also found a lot of dead honeysuckle. This is an area called Woodland Mound Park, just east of Cincinnati, where I’ve been working since 2005. I did not collect data there last year, so I don’t know if the leaf blight led to these particular honeysuckles dying, but let’s just say that circumstantial evidence is high, since there was a lot of blight all over the area last year. This is also the first time I’ve seen enough dead honeysuckles to notice (mainly medium-sized bushes a few feet high).

Once again, I’ve mainly seen the blight on vigorous growth, i.e., on stems that haven’t yet lignified.

I would ask you to again report any sightings of leaf blight you see on any honeysuckle species. I’ve included a couple of pictures that may help. I spent the last two weeks in in New England, where I mainly saw Tatarian and Japanese honeysuckle, and I didn’t notice any leaf blight there.

Volunteers needed in the Ohio River Basin to map purple loosestrife

Picture1CHIP-N (the Central Hardwoods Invasive Plant Network) is a partnership between the Appalachian Ohio Weed Control Partnership, River to River Cooperative Weed Management Area, and Southern Indiana Cooperative Invasive Management. CHIP-N and the Ohio River Basin Fish Habitat Partnership are working together to coordinate the volunteer mapping of purple loosestrife in the Ohio River Basin. This data will help local and regional managers determine the best management strategies and identify possible biocontrol release points. Purple loosestrife is very easy to identify from July-September and would take minimal effort to report it while conducting other activities (water sampling, surveying, canoeing, hiking, etc). If you are interested in participating, please contact Eric Boyda (, 740-534-6578) and he will forward you on more information about what data to collect and how to easily identify purple loosestrife.

This is a great opportunity for organizations to get volunteers interested in reporting and mapping invasive species and possibly expand their programs in the future to include more or different species. Please forward this on to anyone you think would be interested.

AOWCP success: invasive plant scavenger hunt

On Saturday June 8th, the AOWCP set up an invasive plant scavenger hunt for children for the Play Outside Weekend on the Wayne National Forest in the Leith Run recreation area (Washington County).  We had a lot of fun working with the children and their parents (approximately 30 children, 20 adults), and I think everyone learned quite a bit about invasive plants.  It was rewarding to find out that many of the children there already knew what invasive organisms were.  Repeat messaging works, and it’s important that we keep youth informed.


Evan Siembida, a summer intern from Hocking College, stands infront of our display at the scaveger hunt starting point.

Weed wrench test

Invasive Plant Control, Inc was kind enough to donate an extractagator, a shrub wrench you can use to pull up woody invasive plants, to the AOWCP. Below is a picture of it in action, pulling up some oriental bittersweet.


It worked very well on the tap root of the oriental bittersweet.


A privet we tested it on took a little longer, but we still got it out.  Judy Dumke poses with our victim.


Weed wrenches can be a great way to reduce invasive populations in small areas,  but it requires patience,persistence, and a lot of sweat!

Garlic Mustard control on the Vinton Experiemental Forest

These past few weeks the AOWCP has been working with OSU-Extension and the USFS Northern Research Station to control garlic mustard at the Vinton Experimental Forest.


This garlic mustard has already been sprayed and has noticeable signs of stress.  Most plants will take several days to weeks to finally die.

This time of year is also a great time to spray garlic mustard seedlings that germinated this spring.


Hopewell Culture National Historical Park seeking public input and comments on an invasive plant management plan

Hopewell Culture National Historical Park, in collaboration with the National Park Service’s Heartland Inventory and Monitoring Network, is seeking public input and comments on an invasive plant management plan. This document will guide the park in eradication, control, or containment of exotic invasive plants, particularly in natural and cultural areas of the park. Several options for attaining the objectives are considered and analyzed for their impacts on the environment. The analysis is part of an Environmental Assessment. Invasive exotic plant species are defined as non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health.Some examples of such plants species being controlled by the park are bush honeysuckle, Canada thistle and garlic mustard.

The plan is available online at . The plan is open for comment until March 14, 2013.

AOWCP helps local groups establish native plant garden demonstration site

Benefits of Cooperative Weed Management – guest blogger Kate Howe

Invasive species present a huge challenge to anyone who owns or manages land, whether it be a backyard garden, a small wood lot, a city park, or a national forest.  If you have ever spent time trying to reclaim a forest understory dominated by bush honeysuckle or pull garlic mustard sprouting up among native spring wildflowers, you have experienced first-hand the frustration of coming back year after year to treat the same species.  Even if you manage to get rid of every stem of a particular invasive plant on your property, you will still have to return year after year to monitor and treat new seedlings if your neighbor still has that invasive plant on an adjacent property.  Invasive plants don’t see property lines, and they will set up shop anywhere they can find an opening.  To be successful at ridding our gardens, parks, and natural areas of invasive plants, we need to deal with invasive plants on a larger scale, taking a coordinated approach to prevention and control across the entire landscape.

How can we ever hope to manage aggressive and persistent invasive plants across and entire landscape?  By cooperating with our neighbors.  Cooperative Weed Management Areas (CWMAs) (also known as Cooperative Invasive Species Management Areas (CISMAs)) have sprung up across the country to try to address invasive plants at a scale that will be more effective for long-term management.  CWMAs bring together public and private landowners and land managers at a local level (often one or a few counties, watersheds, or ecoregions) to work together on solutions to their shared problems.  Some of the ways that CWMAs have improved invasive plant management are:

          Coordinating the timing of control efforts for a particular species across different properties for more effective control

          Creating shared priorities for invasive plant management so control efforts are more organized

          Pooling resources for outreach and management to enable the completion of larger projects

          Sharing information on new invaders in the area to improve early detection

          Reducing redundancy by creating a complementary approach to invasive plant activities, with each organization contributing time, money, supplies, services, volunteers, or information as they are able

CWMAs have had great successes in early detection, on-the-ground control, and raising awareness about invasive species in their areas.  Here are just a few of the things that CWMAs have been able to accomplish in the last few years.

          The Northwoods CWMA in Wisconsin got their local road department to alter roadside mowing and maintenance activities to prevent the spread of invasive plant seed by road department equipment.

          The River to River CWMA in Illinois created a Strike Team that treated 25 invasive plant species on over 1600 acres in the CWMA in 2011.  The Strike Team also found and treated 11 populations of new invaders, including kudzu, Japanese chaff flower, and burning bush.

          The Southern Indiana CWMA trained a team of volunteer Weed Watchers to identify and report new infestations of 18 priority plant species.

          The Hawkeye CWMA in Iowa holds an annual field day to educate the public about invasive plant identification and control.

          Several CWMAs have created community tool sheds with shared resources (e.g. backpack sprayers, loppers, shovels) for all partners to use.

          Many CWMAs have set up booths at local farmer’s markets, county fairs, or other events to provide brochures and answer questions about invasive plants for the general public.

Setting up a CWMA takes some time and some planning, but the payoff can be well worth the investment.  The Midwest Invasive Plant Network encourages local landowners and interested public in Appalachian Ohio to join the Appalachian Ohio Weed Control Partnership and help in their efforts. 

The Midwest Invasive Plant Network is an organization focused on reducing the impacts of invasive plant species in the Midwest.  Our goal is to improve the quality and quantity of information available on invasive plants to assist with education, prevention, early detection, and control.  Visit our website to see what we have to offer (  The Midwest Invasive Plant Network has created several educational materials on invasive plants that are available at low or no cost.  For more information on our publications, visit

If you don’t live within the boundaries of the Appalachian Ohio Weed Control Partnership, check our map  to find a CWMA in your local region.  Still can’t find one? Consider working with others in your area to develop a new CWMA.  On our CWMA resources page (, you will find a step-by-step guide to starting a CWMA, called the “CWMA Cookbook”, as well as a companion PowerPoint slide show.  You will also see links to sample organizing documents for CWMAs and links to CWMA websites. 

Invasive plants are a daunting problem, but the Midwest Invasive Plant Network is here to help.  We hope you will consider starting or joining a local CWMA to help get the upper hand on invasive species in your area.
