The Wood Buffalo National Park (WBNP) Bison Abundance database is a data set that documents numbers of bison observed during bison population estimate surveys conducted in WBNP. Survey methodology was standardized from 2002 to present. A strip transect survey allows for both minimum counts and a population estimate with accompanying estimates of precision. Survey intervals have ranged from 2 to 5 years. The study area is based on the subpopulation boundaries outlined in Joly and Messier (2001), and is thought to include the entire ranges of the Delta, Garden River, Hay Camp and Nyarling subpopulations, as well as about half the range of the Little Buffalo subpopulation.
Wood Buffalo National Park was created to protect habitat and prevent extinction of the Wood Bison (Soper 1941).
