Traditionally, abundances of moose in B.C. are assessed using periodic Stratified Random Block (SRB) surveys. In two studies in north-eastern B.C., undertaken in collaboration with Wildlife Infometrics Ltd., we reassessed data on moose densities derived from an alternative sampling methodology - distance sampling using aerial transects, and explored sources of uncertainty. The studies concluded that distance sampling is a viable survey method for moose in B.C., but that independent studies of detection distances in different habitat types and topographies is critical for future applications.

- comparison of density estimates to previous analyses
- concluded that shapes of the moose detectability curve contributes significant uncertainty in estimates.
