    Are Native-Species Planting Mandates Good for Biodiversity?


    Many municipalities now require a certain percentage of native trees and shrubs in new landscape installations. Introduced woody species are increasingly perceived as undesirable, primarily because they are lumped together with their invasive counterparts. This presentation will summarize the current science regarding the effects of native and nonnative tree species on urban landscape stability. A more practical approach than simply mandating more native species will be suggested.
