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!

FMR's ecologists investigate how to suppress buckthorn

As anyone who's joined FMR at a restoration volunteer event knows, buckthorn is particularly difficult to eradicate. This invasive plant often thwarts restoration efforts by returning to sites where it's been pulled and hauled away. What if we could find a way to suppress its regrowth?  >>

Art from invasives: An interview with Kim and Emily

FMR volunteers Kimberly Boustead and Emily Sauer remove buckthorn, garlic mustard and more at our stewardship events. And they also use their creativity to spread awareness about how to stop the spread of invasive species. Read more about their favorite river spots, buckthorn berry ink and a new spin on the muscle tee.  >>

What's the best way to control buckthorn and protect native plants? FMR investigates.

What pops to mind when you think of restoring a forest? Perhaps people planting trees? ...How about bobcat-like machines busily eating up small trees and spitting out the splinters?

If you'd visited Hampton Woods this spring, this is exactly the scene you would have come across. The machines were forestry mowers, consuming invasive European buckthorn.

Not only were the mowers benefiting the long-term health of the forest, but they're part of a new FMR research project to compare and contrast the effectiveness of different methods to both control buckthorn and support the growth of native plants and habitat. >>

Beautiful berries 'ecological traps' for birds
Each fall, two common invasive plants produce starkly colored berries. Both have little-known consequences for birds. Read more

A virtual invasive plant species walk with FMR ecologists

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

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.
