Service Description: This layer was created as part of Esri’s Green Infrastructure Initiative and is one of five newly generated companion datasets that can be used for Green Infrastructure (GI) planning at national, regional, and more local scales. If used together, these layers should have corresponding date-based suffixes (YYYYMMDD). The corresponding layer names are: Intact Habitat Cores, Habitat Connectors, Habitat Fragments, Habitat Cost Surface, and Intact Habitat Cores by Betweeness. These Esri derived data, and additional data central to GI planning from other authoritative sources, are also available as Map Packages for each U.S. State and can be downloaded from the Green Infrastructure Data Gallery.

This layer represents the modeled Least Cost Paths (LCPs) among neighboring Intact Habitat Cores.  Least cost paths reflect the route of least resistance between neighboring habitat core edges, and by extension, represent possible paths of wildlife movement. Esri generated this comprehensive network of LCPs using the Cost Connectivity tool which was introduced in ArcGIS 10.4 and ArcGISPro in 1.3. The Habitat Cost Surface layer was used as the input computational surface. The resulting network was also utilized to compute Betweenness Centrality attribution for the Intact Habitat Cores by Betweenness layer, denoting a measure of the Core’s connectivity importance compared to all others in the network.

The PathCost field represents the non-directional cumulative cost of this route. Cost is not accrued for movement within habitat cores, thus the portion of each path that falls within a core’s boundary should be considered schematic only. These paths can be used to create a network dataset for use in additional analysis. If a network dataset is created, it should be cost-based, rather than length-based due to the schematic and costless nature of traveling within a core. The PathCost, LowCoreValue, and HighCoreValue fields were used to generate a network graph.

While least cost paths are useful for illuminating the discrete path of least resistance from one location to another, they should not be interpreted as least cost corridors. Least cost corridors expand least cost paths to encompass functionally larger areas that may facilitate species movement.
