Omnidirectional connectivity for the Andean bear (Tremarctos ornatus) across the Colombian Andes

ContextConserving or restoring connectivity is a common objective of landscape-scale conservation initiatives. However, precise species occurrence movement data to inform validate spatial models are often lacking.ObjectivesOur objectives were (1) produce the first approximation country-wide for Andean bears (Tremarctos ornatus) in Colombia and (2) demonstrate novel approach model validation which uses publicly available web social media records flagship species.MethodsWe used general knowledge about bear habitat associations indices ecological integrity construct resistance surface across Colombian Andes. We this omnidirectional using circuit theory. validated our with coarse location acquired from local news stories posts.ResultsOur was most sensitive changes values agricultural landcover mid-elevational zone, but uncertainty analysis demonstrated these had little impact on conclusions regarding municipalities conducive movement. Just over one-third those areas within protected areas, while 8% coincided landcover.ConclusionsWe constructed that did not rely independent, empirically derived data. Our (1 km resolution) can still provide useful information practitioners who working scarce More how move through landscapes would help improve understanding Colombia.
