Results of recent studies have indicated that the amount edge habitat in an area may be important factor determining home range size pumas. We tested this hypothesis with data on ranges pumas southern Idaho/northwestern Utah. The study is highly fragmented into forest patches and sagebrush open areas. three predictions: (1) percent would negatively related to size, (2) similar, regardless (3) there more within boundaries than general areas similar size. Home (90%) varied from 29.8 118.7 km2. was correlated (F = 22.3, P < 0.001, R2 0.53), but not. mean (16.0 ± 1.4 (se) %) significantly greater (t 2.88, 0.006) (11.3 1.2%). concluded influencing ranges. proposed needed a certain minimum (hunting habitat) successfully hunt their prey "catchable" just abundance.
