Invading species can extinguish native plants despite recent reports
Date:1/9/2013

nd coupled their results with quantitative models to determine the long term impacts of invasive grasses on native plants.

"Invasion has created isolated 'islands of native plants' in a sea of exotics," says Gilbert. "This has decreased the size of native habitats, which reduces seed production and increases local extinction. It also makes it much harder for native plants to recolonize following a local extinction."

"Our research also allows us to identify how new habitats for native flora could be created that would prevent extinction from happening. These habitats would still be too marginal for invaders, but placed in such a way as to create 'bridges' to other habitat patches," says Gilbert.
