A team of committed representatives is currently meeting with southeastern Wisconsin roadside maintenance crews to deliver location and population size data for five invasive species which were mapped in 2011, 2012 and 2013 through the efforts of more than 150 SEWISC volunteers. Wild parsnip (Pastinaca sativa) was mapped by citizen scientists in 2012 while common and cut-leaved teasel (Dipsacus sylvestris and D. laciniatus), common reed grass (Phragmites australis) and Japanese knotweed (Polygonum cuspidatum) populations were the target of 2011 efforts.
With the aid of Great Lakes Restoration Initiative funding through the Environmental Protection Agency, the Ozaukee Washington Land Trust (OWLT) has partnered with SEWISC to schedule meetings with key representatives in more than 100 cities, towns and villages in Washington, Sheboygan, Ozaukee, Milwaukee, Racine and Kenosha Counties.
Nearly 5,000 poulations of target invasive plant species were mapped by our volunteers.
How You Can Help Stop the Spread of Invasives on Roadways
Develop a program by following the guidelines in the SEWISC ROW Invasive Species Management Plan. The basic elements of a program to contain and control invasive plants on right-of-ways are simple to prioritize and outline:
Unless resources are available to accomplish all of these priority control tasks, aggressive and more costly control of well-established populations should only be conducted if it can be justified for specific localities (e.g. a roadside population poses a definite threat to an adjacent high-quality natural area). DO NOT spread established populations!
