Delaware Natural Heritage Program

The Delaware Natural Heritage Program operates as the primary biotic inventory and conservation data center for Delaware (state), maintaining comprehensive information on rare species, natural communities, and ecologically significant habitats. It supports decision-making for land use, resource management, and biodiversity protection across agencies such as the Delaware Department of Natural Resources and Environmental Control, regional planning bodies, and non‑governmental organizations including The Nature Conservancy and Ducks Unlimited. The program integrates field survey, GIS mapping, and stakeholder coordination to guide conservation of sites from the Delaware Bay shoreline to the Piedmont.

Overview

The program compiles and curates inventories of rare plants, animals, and natural communities in collaboration with institutions like United States Fish and Wildlife Service, U.S. Geological Survey, National Park Service, University of Delaware, and Delaware State University. It produces standardized element occurrence records aligned with frameworks used by the Association for Biodiversity Information and the NatureServe network, contributing to statewide conservation planning, regulatory review under statutes such as the Endangered Species Act and coordination with regional efforts like the Mid-Atlantic Regional Council on the Ocean. Stakeholders include municipal planners, land trusts such as Land Trust Alliance members, federal entities like Army Corps of Engineers, and private conservation partners.

History

The program was established in the early 1980s amid growing national efforts exemplified by organizations including The Nature Conservancy and federal initiatives led by the United States Fish and Wildlife Service and U.S. Geological Survey. Early collaborations involved academic partners such as the University of Delaware and conservation groups like Delaware Nature Society to document occurrences of species protected under the Endangered Species Act and to inventory habitats similar to projects conducted by the Natural Resources Conservation Service. Over subsequent decades the program expanded its capacity through partnerships with regional data networks including NatureServe and through adoption of technologies from the National Biological Information Infrastructure and the Geographic Information System community led by vendors and agencies such as Esri and NOAA.

Mission and Activities

The mission centers on documenting biodiversity, assessing conservation status, and informing land use and resource decisions used by agencies like Delaware Department of Transportation and Delaware River Basin Commission. Core activities include field surveys modeled after protocols from National Park Service inventories, habitat classification aligned with standards from U.S. Forest Service and U.S. Fish and Wildlife Service, and maintenance of databases interoperable with NatureServe and federal data systems. The program provides technical assistance to conservation organizations such as The Conservation Fund and municipal bodies, supports environmental review under state laws influenced by precedents from cases handled by entities like the Environmental Protection Agency, and contributes to outreach with partners including State Parks (United States) and botanical institutions such as the Smithsonian Institution.

Data Collection and Mapping

Data collection follows standardized methodologies employed by networks like NatureServe and laboratories affiliated with U.S. Geological Survey and academic centers such as Rutgers University and Penn State University. The program uses geographic datasets compatible with National Hydrography Dataset and mapping tools from Esri for producing conservation maps of features including tidal marshes, coastal plain grasslands, and riparian corridors draining to Delaware Bay. Records are managed as element occurrences with metadata consistent with the Darwin Core standard and shared with partners including USFWS National Wetlands Inventory and regional entities like the Appalachian Landscape Conservation Cooperative.

Conservation Partnerships and Programs

The program partners with statewide and national organizations: Delaware Department of Natural Resources and Environmental Control, The Nature Conservancy, Ducks Unlimited, Delaware Audubon Society, Land Trust Alliance affiliates, and federal agencies such as the United States Fish and Wildlife Service and Natural Resources Conservation Service. Collaborative initiatives include species recovery planning for taxa recognized by Endangered Species Act listings, habitat restoration projects funded through programs similar to North American Wetlands Conservation Act grants, and landscape-scale conservation planning coordinated with bodies like the Chesapeake Bay Program and the Mid-Atlantic Fishery Management Council.

Notable Projects and Achievements

Notable efforts include comprehensive inventories and mapping of Delaware Bay shorelines, conservation assessments for threatened taxa such as coastal plants and migratory shorebirds protected under agreements like the Migratory Bird Treaty Act, and contribution to restoration projects on barrier islands and tidal wetlands in coordination with U.S. Fish and Wildlife Service refuges and state parks. The program’s datasets have informed land protection transactions with partners including The Conservation Fund and recommendations integrated into state planning documents used by agencies such as Delaware Department of Transportation and regional conservation strategies with the Mid-Atlantic Regional Council on the Ocean. Its work has been cited in environmental assessments used in regulatory processes involving the Army Corps of Engineers and in academic studies from institutions like the University of Delaware and Rutgers University.
