Invasive plants

Forests, prairies and savannas all work best when they're shared. But invasive species spread rapidly and make it hard for other plants to grow — plants that help hold soil in place, plants where birds nest, plants that make up vibrant, interconnected habitat.

Overgrowth of invasive species can cause habitat breakdown, erosion of soil into waterways, the spread of plant diseases and more. That's why we focus so much on removing invasive species and replacing them with diverse plants at our restoration sites. Join us!

A virtual invasive plant species walk with FMR ecologists

August 7, 2017

Ever wonder what keeps FMR ecologists up at night? Buckthorn and crown vetch may have pretty glossy leaves or flowers, but for anyone who cares about wildlife, they're a serious threat to forest and prairie habitat in the metro river corridor.

Join FMR ecologist Alex Roth for a walk through our most common invasives: buckthorn, bush honeysuckle, garlic mustard, burdock, spotted knapweed and crown vetch. Along the way, you'll learn why they matter and how to identify and remove them in your own back yard. All in two minutes!

Thank you Tom Reiter and Will Stock for creating this wonderful video!

The green amidst the gray: the distinctive phenology of non-native shrubs

by Alex Roth

November 9, 2015

It’s finally (or already!) November and the leaves have fallen from the trees. Well, not quite all of them. If you take a close look at a nearby forest, you’ll likely notice a dense layer of green still present in the shrub layer. What are these shrubs and why are they still green when other species have all dropped their leaves? In and around the Twin Cities, it’s a good bet that these shrubs are either common buckthorn or one of a few species of bush honeysuckles, and their “distinctive phenology” actually plays a large part in their success in Minnesota’s forest ecosystems.
