Nine Boreal toads (Bufo boreas) were captured during the summer of 1999 at the Snake River Quarry and fitted with telemetry transmitters. Locations were determined approximately once each week. Females may be leaving the quarry site around mid-summer while males remain in the area throughout the summer. Toads preferred two aquatic sites until around mid-July then dispersed to dryer terrestrial areas with a preference for 3 sites characterized by loose soil, which provided good burrow shelter. This quarry is to undergo major reclamation efforts. It is recommended to: 1) stay major construction disturbance until the females undertake their seasonal departure from the area, 2 ) preserve the breeding and preferred aquatic habitat and 3) capture male toads from the preferred terrestrial areas and reintroduce them back after reclamation is completed.
