Subjective uncertainties in habitat suitability maps

摘要: Habitat suitability maps are very useful for planning management and conservation priorities. Epistemic uncertainty usually is an intrinsic part of the mapping process yet, subjective uncertainties have rarely been addressed. Subjective arises from judgments, generally by experts, on how to interpret data translate them into a model. This study examines encapsulate in pair ‘bounding’ habitat maps. These represent extremes range plausible obtained alternative ways model suitability. Sambar deer (Cervus unicolor) was used illustrate within spatial context alpine areas Victoria southern Australia. Four variables (presence forest, distance forest edge, presence gullies, amount solar radiation) three models were retained. A total 22 equally compared with different statistics (sum index, connectance least-cost distance) obtain bounding maps, each linked potential application this species. The gave results, emphasizing importance considering subsequent analyses. Very large bounds found when estimating population size through sum values. With pairs Alpine area or State as whole considered. Using distances, we that surrounding choice much more important than computing variables. can be effectively propagated analyses use if analysis known. could therefore assessed decision-making ecology would better informed.
