Site description (2001 baseline)
The Central Cape Breton Highlands lie south of Cape Breton Highlands National Park in northeastern Nova Scotia. The highlands are mountainous and interspersed with streams and occasional small lakes or ponds. The natural forest here is a mix of Balsam Fir and White and Black spruce, with stunted windblown and moose-browsed forests at higher altitudes. In places bogs and barrens are intermixed with patches of spruce forest. In the 1960s and 1970s there was a large Spruce Budworm outbreak that affected many fir and spruce trees. South of the national park, much of the affected forest has since been salvage-cut in order to use the wood. This has made access to the area relatively easy because of the presence of numerous logging roads. After cutting, most of the forest was left to regenerate naturally and many of these young forests are primarily coniferous with smaller amounts of birch and mountain ash. Smaller amounts of cut forest have been planted with Black Spruce. Silvicultural practices also include thinning and pesticide use, but these are used on a relatively small scale.

The highland region of Cape Breton Island has a mean annual temperature of less than 50C and about 1500mm of precipitation each year. Much of the precipitation is snow, which covers the ground from mid-November to early May. Animals found in the area include: Lynx, Moose, White-tailed Deer, Snowshoe Hare, Red-backed Vole, Mink Frog, and Yellow-spotted Salamander.

Key biodiversity
Scattered throughout the forests of the central Cape Breton highlands are significant numbers of Bicknells Thrush. Between 50 and 200 territorial males are estimated to occur in the area. It is not clear if these numbers reflect pairs of thrushes since some new research suggests that male Bicknells Thrushes may mate with more than one female. These numbers may represent as much as 4% of the worlds population of the species, and perhaps 11% of the Canadian population (using the most conservative national and global population estimates).

At this site, thrushes are found in young, 20 year-old, high elevation forests that have been left to regenerate naturally. These forests, like those that Bicknells Thrushes are more typically found in, are dense and small, usually 2 to 5 m in height. Breeding has not been confirmed in this newly discovered habitat, but since the nests are notoriously difficult to find, this may only reflect the elusiveness of the bird.
