Locations with high values have a greater capacity to facilitate the movement of multiple terrestrial species and maintain ecological processes. Potential linkage pathways for terrestrial features within the M2B study area show connectivity between protected area nodes across a human modification resistance surface.

Mapper to map the most cost-effective route between adjacent protected areas (i.e. nodes), using an index of human influence to approximate the difficulty of movement between locations (i.e., cost surface). Nodes were protected area locations > 50 acres in size, collated from the California Protected Area Database (2016a; calands.org) and amended to include additional properties managed by M2B stakeholders. The cost surface was a species-independent index of human modification based on stressors such as land use; land cover; and presence, use, and distance from roads (Theobald 2013; Dickson et al. 2016; data provided by The Nature Conservancy). Linkage Mapper specifications were set to include three potential connections and exclude linkages that intersect nodes. Linkages were clipped to a cost-weighted distance of 25 km, and scaled from 0 (low) to 1 (high).
