Range

  • North America: Range extends from the Great Slave Lake, Hudson Bay, and Labrador, Canada, south to southern New England, Kentucky, Nebraska, New Mexico, and Arizona, west to south-eastern British Columbia, eastern Washington, eastern Oregon, and eastern California.
  • B.C.: Creston Valley Wildlife Management Area and Bummer Flats
  • Columbia Basin: as above

Habitat

  • Wetland, riparian, stream, small lakes
  • Require 3 distinct seasonal habitats: shallow open water for spring breeding, summer foraging grounds and deep water for hibernation over-winter
  • Northern leopard frogs live in the vicinity of springs, slow streams, marshes, bogs, ponds, canals, flood plains, reservoirs, and lakes; usually they are in or near permanent water with rooted aquatic vegetation

Reproduction

Mating takes place between late April and early June in shallow open water. Males produce a unique call which consists of a series of snores, chuckles and grunts to attract females. Each female mates once, lays a single egg mass containing up to 7000 eggs, and leaves the pond; males probably mate more than once. Eggs hatch in 9 to 20 days and tadpoles metamorphose in mid-summer
