Corridors are made up of the least disturbed and therefore the best potential lands available to unite core conservation areas. These are key landscapes that provide opportunities for biodiversity while contributing to the greenways overall ecological richness.The hubs and corridors are the major concentration of the map and serve as the core conservation areas in the PA Highlands Greenway. The hub and spoke system was created by AMC by combining the results of two analysis techniques, stronghold analysis and the Natural Lands Trusts Smart ConservationTM.. Stronghold analysis identifies areas that are least affected by man-made disturbances such as roads and fragmentation of the natural landscape while Smart Conservation determines the ecological health of an area. The combination of these two analyses in conjunction with the knowledge of local stakeholders was used to prioritize core conservation areas.
