Summary of the 2007 Post Calving Survey for the Itcha Ilgachuz Caribou Herd, Cariboo Region	2007	On June 18th and 19th, 2007 the Itcha-Ilgachuz Mountains caribou herd was aerially surveyed in an effort to determine population status and calf recruitment. During this post calving survey a total of 1784 caribou were observed; including 1021 cows, 432 calves, 237 bulls, 90 yearlings and 4 unclassified adult caribou. The calves represented 24% of the population or 42.3 calves/100 cows. The bull ratio was observed at 23.2 bulls/100 cows, substantially lower than the minimum provincial target of 35bulls/100 cows. The yearling component of the population also appeared low, represented by 7.1 yearlings/100 adult caribou. Higher than average snow accumulation over the previous winter delayed green-up of the inventoried high elevation areas. This delayed availability of forage likely resulted in the decreased sightability of both adult and yearling bulls.	wsi_5955_rpt_2007PostCalvingSummary.pdf
Population Status and Trends From the 2009 Post Calving Survey for the Itcha Ilgachuz Caribo Herd	2010	As part of ongoing monitoring, the Itcha-Ilgachuz northern caribou herd was surveyed aerially in June 2009. Objectives of the survey were to i) obtain a total count with classification and ii) assess current population status and trends of the Itcha-Ilgachuz caribou herd.	wsi_5955_rpt_2009.pdf (181 KB)
