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!
