Habitat Parameters

As short-term effects of partial cuts generally decrease available cover for snowshoe hare ( Lepus americanus Erxleben), most studies have shown negative effects of such treatments on this keystone species in boreal ecosystems. This study aims to determine the long-term impact of commercial thinning on snowshoe hare habitat, and we hypothesized that habitat quality, as well as habitat use, recovers with time since treatment. We selected stands aged 50–90 years dominated by black spruce ( Picea mariana (Mill.) Britton, Sterns & Poggenb.) in Abitibi (Quebec). We used models of habitat parameters to explain the abundance of snowshoe hare tracks and pellets in 20 commercially thinned stands treated between 1989 and 1999 and 12 control stands. Lateral cover was the dominant parameter influencing snowshoe hare habitat use. On average, commercially thinned stands had a lower lateral cover than controls (–18%). We also found that snowshoe hare use of commercially thinned stands increases with time since treatment. However, 11–18 years are needed before commercially thinned stands return to the same level of lateral cover and snowshoe hare signs as control stands. Commercial thinning is generally followed by harvesting all merchantable stems 15 years after treatment. Thus, we suggest that commercial thinning as currently practiced should be avoided if the objective is to maintain quality habitat for snowshoe hare and its associated predators.

Mature Stands

We assessed snowshoe hare (Lepus americanus L.) habitat use during winter on two precommercial thinning treatments in sapling stands in northwestern Montana, USA. One treatment type retained 0.2-ha patches of unthinned saplings, representing 8% of the total stand area, and the second retained 0.8-ha patches of unthinned saplings, representing 35% of the stand area. Snowshoe hare habitat use was also estimated within a nearby control sapling stand and mature conifer stands. We used snow tracking and fecal pellet counts to estimate use before and after thinning treatments were applied. Although we did not find a conclusive trend in hare use of sapling stands after thinning, use within the control stand and adjacent mature stands suggested there was considerable movement of hares to nearby untreated stands after thinning. Hares used retention patches regardless of size, even though large retention patches were four times larger than small retention patches. Because hares demonstrated an affinity for dense patches of residual forest, any retention of untreated saplings may be beneficial for hares during winter when applying precommercial thinning treatments in areas where stand sizes are relatively small (10–14 ha), and the resulting thinned matrix is less harsh than in larger thinned stands. Use within thinned portions of the stand and unthinned remnant blocks suggests that over the winter hares may also benefit from a connectivity of dense cover.

A trailing study of fisher (Martes pennanti) and marten (Martes americana) in the boreal forest of Manitoba, conducted over two winters, showed that both species preferred coniferous ridges. They also had temporal differences in their habitat use that could be partially explained by their different responses to soft snow cover. Movements of fisher were found to be restricted by the soft, thick snow cover that was present during midwinter. Fewer tracks were observed at that time, and fisher travelled upon snowshoe hare trails and their own trails more than in either the early winter period of thin snow cover or the late winter period of crust conditions. Fisher were also found to walk through the snow cover and leave a body drag in midwinter. Marten did not appear to be hindered by soft snow cover to the degree that fisher were. Marten tracks were encountered with equal frequency throughout the winter and marten never left a body drag in the snow cover. They did travel upon hare trails and their own trails to a greater extent in midwinter, but never as much as did fisher.

Most studies of cetacean habitat use do not consider the influence of anthropogenic activities. We investigated the influence of environmental and anthropogenic variables on habitat use by humpback Megaptera novaeangliae and Bryde’s whales Balaenoptera brydei off the coast of the Brazilian city of Rio de Janeiro. Although there are 2 marine protected areas (MPAs) in this area, few data are available on cetacean habitat use or on the overlap of different cetacean species within these MPAs. Our aim was to evaluate the effectiveness of the MPAs and propose a buffer zone to better protect the biodiversity of the study area. We conducted systematic surveys and developed spatial eigenvector generalized linear models to characterize habitat use by the species in the study area. Habitat use by humpback whales was influenced only by depth, whereas for Bryde’s whales there was the additional influence of anthropogenic variables. For Bryde’s whales, which use the area for feeding, sea surface temperature and the distance to anchorages had a major influence on habitat use. We also showed that neither of the MPAs in the study area adequately protects the hotspots of either whale species. Most of the humpback whale grid cells with high sighting predictions were located within 2 km of the MPAs, while areas of high sighting prediction of Bryde’s whales were located up to 5 km from the MPAs, closer to beaches. Our findings provide important insights for the delimitation of protected areas and zoning of the MPAs.
