That you must close your windows
At night to keep it out of the house
The glass is tinged with green, even so
As tendrils crawl over the fields…”

I grew up in Georgia, where on a hot, humid summer day you could almost hear the hiss of growing vegetation, especially the Kudzu as it climbed over fence posts and encroached upon the roadside, the king of invasive species. In Florida you worry about the alligators along the roadside if you have a flat tire; in Georgia, beware the Kudzu.
Invasive species, animal and plant, are an issue in all ecosytems. Imported from distant (and not-so-distant) areas both by accident and misguided intent, invasive species are species that have escaped the checks and balances of natural competitors and predators that existed in their native habitats. This lack of predation and competition enables them to outcompete and overrun other species.
Kudzu may be one of the most recognized invasive species in the United States, but it’s probably not the worst. The zebra mussel is an aquatic animal that has invaded our waterways in Wisconsin. Oak savannahs and prairie ecosystems in the Midwest United States are threatened by many invasive plant species like garlic mustard and blister parsnip. The Wisconsin DNR lists nearly 150 restricted and/or prohibited invasive plant species in Wisconsin, including Kudzu (2). Continue reading “Just in Time for Wisconsin’s Invasive Species Month: Goats”
