2019 Itcha-Ilgachuz caribou post-calving population survey	2019	Annual report (Shores, 2019): The 2019 Itcha-Ilgachuz survey was flown June 19th - 21st to assess population status and June calf percentages. The herd has declined by 40% in one year (2018-19). Given the 3-year average rate of decline (-33.4 %, 2017-19), it is possible the herd will be functionally extirpated (< 20 animals) from the Chilcotin in 8 years. 185 total caribou were observed during the survey. This is the lowest number of Itcha-Ilgachuz caribou recorded since post-calving surveys for the herd began in the 1970s. An additional 24 caribou were sighted during follow-up surveys of collared caribou. This resulted in a total minimum count of 209 caribou (66 cows, 58 bulls, 64 unclassified adults, 3 yearlings and 18 calves).	wsi_5955_rpt_2018-2019.pdf (1.7 MB)
