ABSTRACT Aim Anthropogenic threats often lead to range contraction towards the margins of a species historic niche, resulting in increased extinction risk. Here, we investigate niche characteristics current and populations evaluate changes ‘Area Niche’ (AON) following loss from different levels anthropogenic three congeneric Asian gazelle are facing: Przewalski's ( Procapra przewalskii ), Tibetan P. picticaudata ) Mongolian gazelles gutturosa ). Location Tibet, Qinghai Mongolia. Methods We collated maps for contemporary distributions Przewalski's, created 3‐dimensional hypervolume convex hull models using environmental variables Worldclim dataset (v2) together with topographic information SRTM elevation data Area Habitat evaluated over time. calculated Niche by projecting scaled Mahalanobis distance centroid each grid cell onto species' range. Finally, how protected area network overlaps characteristics. Results The endangered has lost almost all its remaining at peripheries. In contrast, near‐threatened least‐concern have less contracted their centre. Protected areas were biased ecological ranges, which can result sub‐optimal conservation strategies. Main Conclusions This study uses modelling occupied that undergone contraction. highlight most affected vulnerable shift These also mismatch between space. advocate strategies should include dynamics as an indicator
