To understand habitat use and selection by wildcats is important for conservation strategies,
especially where human impact is high as in most central Argentina. We aimed to study the use
and selection of the habitat by radiotagged Geoffroys cats in three areas with a variable degree of
human alteration in Pampas grassland/scrubland: Campos del Tuyú Wildlife Reserve (CdT),
Tornquist Provincial Park (TPP) and Los Álamos farm (LA). The average home range sizes were
3.43 ± 1.83 km2 at CdT (n = 303 locations, four individuals), 7.67 ± 2.27 km2 at TPP (n = 254,
three individuals) and 2.08 ± 2.21 km2 at LA (n = 371, four individuals). Habitats with the most
dense vegetation coverage were the most frequently used: dense grassland at CdT (78,2% of
locations, no selection), dense wood patches of exotic trees at TPP (47,4%, positive selection) and
dense natural scrubland at LA (25,3%, positive selection), where also natural grassland and open
scrubland were often used (21.6% and 21.3%). On average, habitat selection tended to increase
with the level of human alteration of the area. Although O. geoffroyi shows a certain degree of
flexibility in its use of habitat, patches with dense vegetation coverage, which could offer both
shelter and availability of prey, appear to be important.2 at CdT (n = 303 locations, four individuals), 7.67 ± 2.27 km2 at TPP (n = 254,
