Missouri Invasive Plant Task Force Unveils Statewide Invasive Plant Assessment Feb. 7, 2019

by Tina Casagrand

New online tool will help prioritize invasive plant management efforts throughout Missouri

Jefferson City, MO (February 8, 2019)—Yesterday, at the Missouri Natural Resources Conference in Osage Beach, MO, Dr. Quinn Long, a member of the Missouri Invasive Plant Task Force (MoIP), presented a statewide comprehensive invasive plant assessment during the workshop organized by MoIP, Invasive Species Collaboration: Informing the Masses, Building the Armies, Stemming the Flow, and Turning the Tide

“One of the biggest threats to Missouri’s—and the nation’s—native plants and animals, and to many facets of our economy, are invasive plants,” said Carol Davit, MoIP Chair and Executive Director of the Missouri Prairie Foundation. “Invasive plants and animals—including that small percentage of non-native plants that, intentionally or accidentally, have been introduced here and have spread rapidly—are second only to outright habitat destruction in the loss of native biodiversity, can have negative impacts on our cattle, timber, and outdoor recreation industries, cause headaches for private landowners, and nationally, cost billions of dollars in control efforts annually.” 

Dr. Quinn Long, botanist, Director of Shaw Nature Reserve, and MoIP member, worked since 2015 to lead the MoIP working group that assembled and analyzed invasive plant data for the assessment. “This assessment—complete with maps for each of the 142 species assessed—will provide a valuable tool for landowners, land managers, and natural resource planners to focus their efforts on invasive plant management,” said Long. The assessment maps depict abundance, impact, and rate of spread of these plants in the state. 

“MoIP is a dedicated group of representatives from land-holding agencies and natural resource management professionals from across the state,” said Davit. “We are pleased to present this important new tool, which is critical to assertive, prioritized invasive plant management efforts. Many individuals have worked very hard to make this assessment possible, including more than 25 reviewers; Phillip Hanberry, contractor with the Missouri Department of Conservation who generated the assessment maps; and Tina Casagrand, MoIP contractor who loaded and linked all maps to the MoIP website, where they are available for all to consult and use.”MoIP is housed and administered by Grow Native!, a native plant education and marketing program of the Missouri Prairie Foundation. The purpose of MoIP—working as a united, supportive front—is to review, discuss, and recommend actions related to managing known and potential non-­native invasive plant species that pose threats in Missouri and elsewhere in the lower Midwest.

Private and Public Property Owners Invited to Pledge to Stop the Spread of Invasive Plants
The Missouri Invasive Plant Task Force, a resource of the Grow Native! program, invites communities, campuses, businesses and other entities to commit to controlling the spread of invasive species on their properties.

Jefferson City, MO (December 3, 2018)—Property owners in Missouri are stitching a curtain of protection against invasive species spreading across the state. By taking the Pledge to Stop the Spread of Invasive Species, administered by the Missouri Invasive Plant Task Force (MoIP), stakeholders from private land, small businesses, the University of Missouri, and other entities are promising to not plant species known to be invasive. They are also budgeting economic and human resources toward controlling against the spread of invasive plants currently growing on their properties.

Few problems are as expensive, visible, and ignored as invasive plants. Estimated to cost the United States between $1.1 to 120 billion per year in economic losses, invasive plant species can lower property values, weaken ecosystem health, and threaten many facets of economic health, from the timber industry to livestock production. Because of their ability to thrive and aggressively spread in disturbed habitats, invasive plants can cost property owners thousands of dollars in remediation if not managed in the long-term. “The longer we ignore the problem the harder and more expensive the battle for control will become,” states the website of the Center for Invasive Species and Ecosystem Health at the University of Georgia.

“We commend all pledge-takers for publicly demonstrating their dedicated effort to stopping the spread of invasive plants,” said Carol Davit, Executive Director of the Missouri Prairie Foundation, the nonprofit conservation organization and land trust that operates the Grow Native! program, and serves as Chair of the program’s Missouri Invasive Plant Task Force (MoIP), a multi-disciplinary, multi-agency group working as a united front to foster greater statewide early detection and control of invasive plants. “We invite other educational institutions, corporate campuses, municipalities, neighborhood associations, and other entities to take the pledge as well to signal their commitment to joining the fight to control invasive plants and mitigate the serious threats they pose.”

MoIP Task Force members developed the pledge with a number of benefits in mind. First, signing the pledge signals the signer will commit resources to control invasive species—action that is increasingly being demanded of campus, business, community, and other entities with invasive plants on that property. Second, the pledge helps stakeholders understand that controlling invasive plants will take time. Additionally, when a community or other entity lets its stakeholders know it has signed the pledge, it provides an opportunity for stakeholders to get involved in the effort.

“Invasive plants are serious threats to Missouri’s native ecosystems, as well as many native plants and animals, the built environment, and many facets of the state’s economy, including cattle production, the timber industry, and many aspects of outdoor recreation, including fishing and hunting industries,” said Davit. “Missouri will control invasive species only with the concerted efforts of many entities, including private citizens working together. Our state is a long-time, nationwide leader in natural resource conservation, and by committing to invasive plant control as well, we can further safeguard Missouri’s habitats, fish, wildlife, and other cherished aspects of our natural heritage.” MoIP encourages educational institutions, corporate campuses, municipalities, neighborhood associations, and other entities to take the pledge.

Entities wishing to sign the pledge may do so via a Google form available at www.moinvasives.org. The Missouri Invasive Plant Task Force (MoIP) can also provide a pledge document suitable for signing ceremonies and framing. Many resources on the identification and control of invasive plants, including native alternatives to invasive plants, are available from MoIP as well.

Download Guidebook on Management of Invasive Plants & Pests of Illinois

by Tina Casagrand

A comprehensive guidebook on Management of Invasive Plants & Pests of Illinois is now available online as a free download:

The book includes clear and direct recommendations for management of ubiquitous and emerging invasive species, including Japanese Hops, Tree of Heaven, Multiflora Rose and many, many more!

Though the guide is for Illinois, the vast majority of these species occur in our region.  As to specific control recommendations, the authors use precise language and clear instruction (clearly stating percentages as v/v as opposed to % active ingredient, clearly differentiating between triclopyr ester and triclopyr amine, etc).

A phenology calendar is available in a special pull-out section.

We are grateful to SIU-Carbondale, Morton Arboretum and University of Illinois Extension for creating this fabulous resource!
