Does scale or method matter for conservation? Application of directional and omnidirectional connectivity models in spatial prioritizations

Introduction The maintenance of habitat connections between fragmented patches is vital for the conservation wildlife populations and ecosystem functioning. awareness connectivity issues species has resulted in a growth modeling application these results planning. Such efforts can include several decisions or data limitations, which could influence ultimately systematic plan (SCP). However, there been little investigation how different on species, scale, extent ultimate planning outcomes. Methods We modeled northern bobwhite ( Colinus virginianus ), North American river otter Lontra canadensis black bear Ursus americanus three with varying ecological requirements, through Congaree Biosphere Region, South Carolina, USA. suitability each using boosted regression trees converted into resistance layers analyses. compared models at multistate regional local extents directional omnidirectional circuit theory approaches. then used from combination as goals SCPs to determine may geographic decisions. Results There was substantial positive spatial correlation appeared be general agreement among mammals most important primary corridors. Across all greatest plan, highlighted unique corridor. required least amount units achieve its goals, followed by plans that over 200 km 2 more land area conserved. Discussion Our indicate overall variations have only moderate impact identification movement corridors scale. Practitioners should base ecology study region, question, available computing resource.
