From the IUCN Red List Species Account:

 

Range Description

This species can be found in south-central Canada and north-central USA, from southern Northwest Territories through Alberta, Saskatchewan, and Manitoba to northern Montana, North Dakota, northeastern South Dakota, and west-central Minnesota (Conant and Collins 1991).

Habitat and Ecology

Its habitat is grasslands, prairies, plains and aspen parklands; areas with relatively soft soil. It is usually found in or near water and burrows into soil when inactive. Eggs are laid and larvae develop in shallow water of lakes, ponds, quiet streams, marshes, potholes, and roadside ditches.

Population

Some local declines have been reported (Green 1997), but provincial conservation data centres rank this species as apparently secure in the main portion of its range in Alberta, Saskatchewan, and Manitoba.

Population Trend

Stable

Major Threats

Generally, there are no major threats to this species. However, local declines and low abundance in Alberta have been attributed to loss of wetlands; low abundance/population fluctuation in Manitoba possibly was due to drought (see Green 1997). Oil and gas exploration has more recently become a threat to habitat.
