Itcha-Ilgachuz Late Winter Recruitment Survey 2023	2023	The Itcha-Ilgachuz caribou herd experienced a rapid population decline of 80% between 2003 and 2019 (Shores 2019). In response to this population decline, a wolf reduction program was initiated in 2020 to recover the Itcha-Ilgachuz caribou population. Late-winter recruitment surveys provide a measure of calf survival to reproductive age, as well as a population response to the wolf reduction program. High calf percentages during late-winter recruitment surveys appear to be responsive to the wolf reduction program, with a 2023 calf percentage of 24.2%, which is the highest that's been recorded in the Itcha-Ilgachuz herd since the 1980's. These results highlight the effectiveness of the wolf reduction program as a short-term recovery measure. The strong year-to-year variation in recruitment correlating with number of wolves removed emphasizes that habitat protection and restoration measures are the long-term and ultimate solution to caribou recovery.	wsi_5955_rpt_2023LW.pdf (942 KB)
