Itcha-Ilgachuz Seasonal Caribou Calf Survival Inventory 2013  2013  This flight was a continuation of the calf survival flight conducted in 2012. Conditions were ideal. Radio signals were assessed to determine which radios were still active. The Itcha-Ilgachuz caribou population has declined approximately 52% between 2003 and 2010. Although there are a range of cumulative effects, the precise cause is unclear. Mining, logging, roads, mountain pine beetle and fire may reduce habitat quality and quantity through the medium and long term, while wolf predation may act through the short and medium term. Cause and effect changes through habitat supply are more difficult to assess, while population changes through wolf predation may be more obvious. OBJECTIVES The purpose of the present survey was to assess population parameters and change between years 2012 - 2013, through the calf component. In the past few years, few seasonal calf indices have been obtained.  wsi_5955_rpt_2013.pdf (352 KB)
