Characteristics of post-parturition areas of moose in northeast Minnesota
Habitat used in the three to four weeks after parturition could be important to calf survival. Newborn calves are vulnerable to predation, and the cow needs adequate forage reserves during the period when calf mobility is limited. Radio collared cows were located by visual observation from helicopte...
