13th Annual Spring Ecology Symposium

"Understanding Plant Invasions in Fragmented Landscapes." Invasive non-native plants have become widespread, but not invariably ubiquitous, in the patches of natural habitat found in suburban and exurban landscapes. Dr. Ehrenfeld will discuss the use of citizen scientists as observers to collect information on occurrence of exotic species, and the patterns of occurrence that emerge from both these data and other studies of exotics in the New Jersey environment.
