Seeking sanctuary: the neonatal calving period among central mountain woodland caribou ( Rangifer tarandus caribou )
Woodland caribou (Rangifer tarandus caribou (Gmelin, 1788)) populations have declined throughout their range. With the goal of better understanding habitat selection and fidelity during the neonatal calving period (0–4 weeks), we applied a noninvasive method that estimates calving events and subsequ...

Woodland caribou (Rangifer tarandus caribou (Gmelin, 1788)) populations have declined throughout their range.

We examined a long-term GPS-collar data set (1998–2014) collected from 81 adult female caribou in two central mountain herds in Alberta and British Columbia, Canada.
