| Objective |
To document the presence and distribution of 5 amphibian species suspected to reside in the Williston and Dinosaur Reservoir watersheds: western toad, wood frog, Columbia spotted frog, striped chorus frog, and long-toed salamander. |
| Methods |
Three techniques were used to acquire data: breeding call surveys, aquatic surveys, and Backyard Amphibian and Reptile Surveys. Breeding call surveys were conducted according to the protocol of the North American Amphibian Monitoring Program. These night-time surveys involved traveling along predetermined roadways and recording all species heard within a 3-minute period. Aquatic surveys were conducted at selected sites when amphibians were likely to be most active and observable (mid-day to early evening). Observers searched shoreline and shallow water areas, with specimens being captured when necessary for identification. Backyard Surveys involved sending survey and identification (e.g., species identification sheets, breeding-call audio tapes) materials to interested persons in remote locations of the Williston Reservoir watershed to record amphibians observed during the April-August period. |
