The Friedman test was applied to this index in order to test the influence of habitat class on moose yard selection (yard = subject, habitat class = treatment).
Moose yards were not located close to uncut forest surrounding the landscapes and did not have a greater proportion of residual forest than clear-cut landscapes.
We also hypothesized that (2) moose yards would be located close to uncut forest surrounding the clear-cut landscapes or in those parts of the landscapes having a higher proportion of residual forest, and that (3) moose yards would be located in parts of the clear-cut landscapes where the shrub layer is more dense and browse more abundant.
The analysis of aerial surveys was done at 2 scales: clear-cut landscapes and moose yards. At the first scale, moose density was computed inside each landscape (excluding the 1-km buffers).
We also compared vegetation in moose yards (n = 11) with random sites (n = 11) selected within clear-cuts in the same landscapes.
The number of moose yards by 500-m distance classes from the uncut forest inside each landscape had a similar distribution to the proportion of the landscape's area by distance classes ([chi square] = 0.02, = 0.99) (Fig.
Moose yards had quite a different vegetation than the clear-cut landscapes where they were located (Table 2).
For the second part of the survey, a helicopter with a navigator-observer and an observer sitting behind the pilot returned to the same plot to count and determine the sex of moose in each moose yard
. Due to the low density of moose within heavily hunted blocks, moose located near the random plots were also sexed and categorized according to their maturity, leading to a larger sampling of the population.
