Maryland's Green Infrastructure Assessment
Mapping Maryland’s Green Infrastructure
The Green Infrastructure Assessment (GIA), based on principles of landscape ecology and conservation biology, identified an ecological network using satellite imagery to characterize land cover, Geographic Information System (GIS) data on road, stream, wetland and other resource features, and biological databases. The model and resulting maps were peer reviewed by scientists and local government staff. Non-natural gaps in the GI were identified as potential candidates for restoration activities.
When complete, the GIA map comprised more than 1.7 million acres in hubs and roughly 250,000 acres of corridors, totaling about 39% of the State’s land area. The network captures nearly all of Maryland’s most important ecological lands.
Data and Mapping
GI data and maps are readily available for agencies and organizations interested in conserving Maryland’s critical natural resources.
