"Marten home range size and movements are likely tied to site quality and prey availability. Marten during my study were very mobile. Gravel roads, paved highways, groomed snowmobile trails, or small streams did not inhibit movements." (p. 72-3)

"What makes these areas attractive to marten most likely depends on the size, amount, and placement of structural elements across the landscape in addition to their association with prey items." (p. 73)

"Presence of marten in southwest Montana is not contingent on abundant quantities of contiguous old growth forest, as marten are not restricted to old growth. Marten do seem to prefer traits associated with more mature timber stands such as larger diameter trees and downed woody material." (p. 73)

"Prey availability must influence habitat selection in pine marten. Because the marten is in many ways maladapted to harsh winter climates, it must have access to a reasonably constant food supply to survive. Cover types favored by marten tended to have more, or more vulnerable, red-backed voles and deer mice than less favored cover types. Habitat structure as well as species composition influenced prey availability." (p. 73-4)
