Using ungulate biomass to estimate abundance of wolves in British Columbia

摘要: Management of wolves (Canis lupus) in British Columbia, as with most other Canadian provinces, is conducted on a regional scale (38,557–252,776 km), yet there no standardized, cost-effective methodology for providing reliable estimates wolf abundance at this scale. Therefore, we used periodic ungulate and incorporated them into an biomass regression model to estimate provincial (900,402 km) over 12-year period (2000–2011). In 2011, the was 8,688 (95% CI1⁄4 5898–11,760) (7–13 wolves/1,000 while ranged from 149 100–205) 2,693 1,818–3,608) differences related (km) rather than densities (4–15 km). We suggest useful management purposes when precise are not required populations heavily exploited or recovering. 2014 The Wildlife Society.
