THIRD ANNUAL LONG ISLAND NATURAL HISTORY CONFERENCE


An evaluation of management, urbanization, and isolation on grassland biodiversity within the Atlantic coastal pine barren ecoregion

Polly L. Weigand, Suffolk County Soil and Water Conservation District

The Atlantic Coastal Plain grasslands are culturally iconic and globally rare ecosystems that provide critical habitat for a diverse array of flora and fauna within a highly urbanized, isolated and fragmented landscape. While ecological value of many of these grasslands has been recognized through preservation and restoration, persistence in the landscape requires regular anthropogenic intervention to retrogress succession and suppress invasive species encroachment. The influence of historic land use legacies, site attributes, management regimens, urbanization and isolation on the floral diversity of the Atlantic Coastal plain grasslands will be highlighted to help advance and refine future conservation and management of these globally imperiled ecosystems.
