Name: Maryland Green Infrastructure - Green Infrastructure Hubs Corridors and Gaps

Display Field: HC_Type

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Maryland’s Green Infrastructure Assessment (GIA) provides high resolution, statewide data regarding the connected network of hubs, corridors, and gaps throughout the state. For the purposes of the MD GIA, hubs were defined as large contiguous blocks of forests and wetlands, corridors are defined as linear features connecting hubs that enable animals and plant propagules to move between hubs, and gaps are defined as areas within corridors that are not currently part of the optimal natural land use type(s). The original GIA was completed in 2003, and included mapping of hubs and corridors using 30m resolution Landsat landcover landuse data. GIA hubs were updated in 2010, using newer Landsat data, however corridors were not remapped at that time. This current update to the MD GIA dataset leverages the Chesapeake Conservancy’s 2017/2018 1m Land Use Land Cover (LCLU) dataset. This update provides the most up to date, high resolution green infrastructure data possible for the state. This data set also contains several improvements, including a more detailed break down of 3 hub types (forest, wetland, aquatic), 2 corridor types (forest and aquatic), and 3 corridor and gap statuses (natural corridor, restorable gap, non-restorable gap).
