Distribution Of The Northern Long-Toed Salamander (Ambystoma Macrodactlylum) East Of The Continental Divide In Montana

Abstract

Over the past twenty-six years there have been a relatively small number of reported sightings of the Northern Long-Toed salamander east of the continental divide near the Helena area. The eastern-most reported sighting was near the Tizer Lakes area in the Helena National Forest. This study of the distribution of the Northern Long-Toed salamander in Montana east of the continental divide is significant because it substantiates the eastern migration currently in progress, provides assumptions about the probable habitat in which they may be found, suggests routes which may have been traversed in the migration over the divide and suggests possible reasons for this migration.
