A MODIFICATION OF A MOOSE POPULATION ESTIMATOR
The enumeration of moose (Alces alces) population to obtain estimates of moose density, and bull:cow, and calf:cow ratios are important to successful management of moose populations. Aerial surveys using the Gasaway-DuBois-Reed-Harbo method, GDRH, (Gasaway et al. 1986) assume that sightability is id...
