Activity Type:
Research
Subject/Discipline:
Herpetology (Amphibians /
Reptiles)
Objectives:
Conduct field surveys and assess
status of species of management concern. We propose to develop a database on
past and recent distribution records, and relate habitat variables that will
provide better opportunities to protect these particular species and their
breeding habitats. Our focus in southwestern Oregon will be on the Cascade frog
(Rana cascadae) and western toad (Bufo boreas) on NPS, USFS and BLM lands.
Findings and Status:
We surveyed at least 4 lentic
sites during summer 2001 for cascade frog and western toad breeding. Larval and
juvenile western toads confirmed breeding in 2001 within the crater itself.
Western toads were also encountered near the Munson Meadow complex. Due to the
drought year, most of the other sites were almost completely desiccated at time
of July/August surveys. We plan to contact Park staff and resurvey these sites
in summer 2002, which appears to be a more normal precipitation year. We also
utilized the Crater Lake National Park museum collection to confirm historical
localities within and outside park boundaries.
For this study, were one or
more specimens collected and removed from the park but not destroyed during
analyses?
