Assessing conservation outcomes and maximizing habitat connectivity for multiple species in systematic conservation plans: a case study in Yolo County, California

Abstract Context Habitat connectivity is key when designing reserve networks for conservation of species at risk. Acquiring land over time to achieve multiple in a systematic plan can pose challenge because not all high priority parcels will be acquired, occurrence data often limited, and using models together complex. Objectives We evaluated four possible acquisition strategies such their ability meet each three objectives. The represent different combinations what are termed ‘Priority 1’, 2’, ‘Corridor’ lands the plan. objectives (1) target acreages identified plan; these distinct from goals, (2) maximize structural habitat connectivity, (3) focal species. Methods For this case study Yolo County, California, we compared efficiency targets MARXAN. MARXAN solutions strategy FRAGSTATS distance between patches ArcGIS. by ArcGIS define species-specific least cost then assessing network’s conformity with solutions. Results 1’ provide most efficient solution attaining targets, highest greatest number Conclusions Because patterns sensitive may recommend spatial prioritization software employing several measures decision-making.
