Typical boreal toad habitat is montane valleys and associated uplands between 7,000 and 11,000 feet in elevation.
Boreal toads usually breed in mid-april to late May in small ponds, wetlands, or in many cases, ponds formed by beaver activity.
Boreal toad eggs are jet black and are deposited in long stands. The “egg mass” usually curls around so it occupies a small, compact area.
Tadpoles are also jet black and range in size from ¼ inch to 2 inches depending on water temperature and age.
Tadpoles frequently congregate in the warm shallow water on the north and northeast side of the breeding pond.
Juvenile boreal toad approximately 2 weeks after metamorphosis.
