2021 Mountain Caribou Census - Central Selkirk Mountains	2021	Census report (Reid, 2021): A census of the Central Selkirk caribou sub population was conducted on March 3 and 4, 2021. The survey conditions were favorable with significant snowfall, which erased old tracks, occurring 5 days prior. The Duncan block of the Central Selkirks subpopulation was not included in this census. A total of 28 caribou were observed which included 26 adults and 2 calves. Despite 3 years of stability, the long-term trend in the Central Selkirk population is declining. The observed count from this census is 87% lower than the peak observed count of 1997 (222 - 28). Calf recruitment at 7.1% is below the suggested 12% - 16% recruitment required for a stable population. Adult mortality from predation was the primary driver of population declines along with chronically low recruitment for the past decade. Low recruitment is likely related to predation but may also be influenced by backcountry recreation disturbance. Recent management actions have been implemented to reduce adult mortality and winter disturbance, but without increased recruitment this population remains at high risk of extirpation.	wsi_5888_rpt_2021.pdf (864 KB)
