Metadata (Data about data or how the map was made)

Martens occur state-wide in mountainous areas. They are found in a variety of forest communities but their greatest density occurs in Engelmann Spruce/Sub-alpine Fir forests greater than 100 years old and having a canopy cover exceeding 30%. Mixed age forests provide the hunting and protection and support the diverse number of prey species, such as, voles, snowshoe hares, other small mammals, birds, nuts and berries. They are arboreal and tend to be absent from very large cuts and burns.

Core zones were Sub-alpine Fir, Mountain Hemlock, Silver Fir, Interior Western Hemlock, Interior Redcedar, Western Hemlock, Interior Douglas-fir, Grand Fir, and open high forest in the Blue Mountains. All forests and wooded riparian habitats are good.
