Maryland Natural Heritage Program The Maryland Natural Heritage Program operates as a state-level conservation inventory and biodiversity information initiative. It inventories endangered species, rare plants, natural communities, and significant habitat within Maryland to inform land use planning, wildlife management, environmental review, and conservation easement decisions. The Program collaborates with federal, state, and nongovernmental entities to support compliance with statutes such as the Endangered Species Act, the National Environmental Policy Act, and state-level statutory frameworks.

Overview

The Program maintains systematic inventories of flora and fauna occurrences across Maryland, compiling records used by agencies like the U.S. Fish and Wildlife Service, the Maryland Department of Natural Resources, the Maryland Department of Transportation, and local county government permitting authorities. Its activities intersect with regional initiatives including the Chesapeake Bay Program, the North American Bird Conservation Initiative, the National Wild and Scenic Rivers System, and landscape-scale conservation efforts such as the Eastern Shore stewardship networks. Data products support environmental review under the Clean Water Act Section 404 permitting and inform conservation planning for landscapes including the Patapsco Valley, the Pocomoke River, and the Appalachian Mountains foothills within the state.

History and Development

Originating in the late 20th century as part of a national trend following model programs like the NatureServe network and state natural heritage programs in Virginia and Pennsylvania, the Program evolved with technical contributions from institutions such as the Smithsonian Institution, University of Maryland, and the U.S. Geological Survey. Early efforts mirrored protocols established by the Natural Heritage Network and used methods refined in projects like the Conservation Data Center initiatives. Over time, the Program expanded to incorporate digital mapping, standardized element occurrence ranking systems adapted from The Nature Conservancy, and cooperative surveys coordinated with the Maryland Geological Survey and regional land trusts.

Mission and Functions

The Program's mission advances protection of Maryland's biological diversity by documenting occurrences of state-listed species, coordinating status assessments for taxa such as freshwater mussels, coastal birds, rare orchids, and vertebrate species including alewife and northern diamondback terrapin. Core functions include maintaining the state's natural heritage database, advising the Maryland Critical Area Commission, supporting environmental impact assessment processes for projects involving agencies like the Federal Highway Administration and the Army Corps of Engineers, and providing technical guidance to conservation partners such as the Audubon Society, the Maryland Sierra Club, and regional land trusts.

Programs and Services

Services offered include field surveys, element occurrence documentation, natural community classification, ecological restoration guidance, and rare species monitoring. Specific programs have targeted initiatives such as coastal habitat assessment for the Chesapeake Bay, freshwater stream assessments coordinated with the Environmental Protection Agency, and imperiled species recovery planning in collaboration with the U.S. Fish and Wildlife Service Recovery Programs. The Program supports citizen science partnerships with organizations like Maryland Biodiversity Project, collaborates with academic partners including Towson University and the University of Maryland Center for Environmental Science, and provides GIS support to planning entities like regional metropolitan planning organizations.

Data Management and Databases

The Program curates occurrence records in interoperable geospatial databases aligned with standards from the Federal Geographic Data Committee and exchange protocols used by NatureServe and the National Biological Information Infrastructure. It produces element occurrence reports, natural community maps, and distribution models used by state agencies, the U.S. Fish and Wildlife Service, conservation NGOs, and private consultants for compliance with Section 7 of the Endangered Species Act. Data stewardship practices reflect guidelines from the Society for Conservation Biology and utilize tools such as GIS platforms from Esri and datasets cross-referenced with the USGS National Hydrography Dataset.

Partnerships and Funding

Funding and partnerships derive from state appropriations administered by the Maryland General Assembly and the Maryland Department of Natural Resources, federal grants from entities like the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration, and cooperative agreements with foundations including the National Fish and Wildlife Foundation and private donors. Collaborative projects have engaged stakeholders such as the Chesapeake Bay Foundation, the Maryland Department of Agriculture, municipal governments (e.g., Baltimore City), regional Council of Governments bodies, and conservation organizations including The Nature Conservancy and local land trust networks.

Conservation Impact and Notable Projects

Notable contributions include inventories that informed restoration of tidal wetlands in the Chesapeake Bay watershed, assessments supporting protection of the Chesapeake Bay Critical Area, species recovery assistance for plants such as the Harperella complex and animals such as the Delmarva Peninsula fox squirrel, and collaborative monitoring of imperiled freshwater mussels in tributaries of the Susquehanna River and Potomac River. Projects with the U.S. Fish and Wildlife Service and the National Park Service facilitated habitat management on lands including Assateague Island National Seashore, Patapsco Valley State Park, and conservation easements across the Eastern Shore. The Program's datasets continue to underpin conservation easement prioritization, mitigation banking reviews, and landscape resilience planning related to sea level rise and climate adaptation initiatives endorsed by the Maryland Commission on Climate Change.
