Book excerpt: This report describes aerial surveys conducted in June 1979 over Hall Peninsula, southern Baffin Island, to document the location & extent of caribou calving areas. Survey methods are described and results are presented regarding numbers of caribou & calves observed, the areas where they were observed, and the geographic characteristics of those areas. Suspected calving areas are delineated and recommendations are made for further research to verify their boundaries and determine their significance.

Book excerpt: The calving grounds of the Beverly caribou herd in the Northwest Territories have been delineated over the 23 years between 1957 and 1994 by the Canadian Wildlife Service and the Northwest Territories Department of Resources, Wildlife & Economic Development, and during monitoring for the Caribou Protection Measures. Survey design, criteria for defining the calving ground, timing & coverage of surveys, and weather conditions have varied from year to year. This report maps the Beverly caribou herd's traditional calving grounds from information in the 1957-94 surveys, compiles flight lines & survey strata for each annual calving ground survey into one report, and determines how frequently the Caribou Protection Area covered the annual calving grounds. It also discusses the technical & environmental sources of uncertainty that influence the mapping of the calving grounds.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides statistical commentary on survey methods used to monitor barren-ground caribou herds in the Northwest Territories (NWT) with an emphasis on intervals between surveys and survey precision. I provide some comments on the statistical design of surveys and some ideas to improve precision. Calving ground photo surveys and post-calving photo surveys are the most important surveys for barren-ground caribou as they provide benchmarks for herd status and management. Results of power analyses suggest that the sampling interval for these surveys should never be less than three years unless a very large change in abundance is expected. For the most likely rates of change in population size (+/- 10% per year) then a survey interval of five to six years is adequate. Composition surveys in June, fall (rut, usually late October), and late winter (March/April) are used to assess initial calf productivity, calf survival to four to five months, calf survival to nine to ten months, and sex ratio (in the fall). Representative sampling across a herd’s range is key to obtaining reliable results. Late-winter surveys are best carried out annually to capture frequently high year-to-year variation. Fall surveys to assess sex ratio are usually carried out in years of calving ground photo surveys (every three years in most NWT herds 2006-2018) and may be conducted more often if a substantial male-dominated harvest is in place. Reconnaissance surveys on the calving grounds of some herds have been used to assess trend in caribou abundance on calving grounds in years between full photographic surveys. They are much simpler and far less costly. However, variance on survey results is usually high and assessment of composition (breeding cows, non-breeding cows, yearlings and bulls) on or near the calving grounds may not be reliable. I provide recommendations to improve precision of these surveys. I note that the primary analyses in this report occurred in 2011 and since then some of the methodologies have evolved. I provide updated citations to this current work.

Book excerpt: This report describes the results of a calving ground photo survey of the Bathurst barren-ground caribou herd conducted June 1-14, 2021 west and east of Bathurst Inlet in Nunavut. The main objectives were to estimate the numbers of breeding females, adult females, and adults in the herd, and to compare results to previous calving ground surveys of this herd, the last in 2018. A calving ground survey of the Bluenose-East caribou herd was carried out simultaneously and results from that survey are reported separately.

Book excerpt: Overall, the preferred June estimate (114,472±15,845) and the preferred July estimate (122,697±31,757) showed overlap of confidence intervals as estimators of BNE caribou herd size in 2010. We believe the July estimate is likely the closest to true herd size as the June survey likely did not include all the bulls, yearlings and non-breeding cows in the herd.
