Under this project staff will:
1) Eradicate fish from 10 to 18 lakes, ponds, and marshes using gill nets, electrofishers, and fish traps.
2) Transport equipment and gear to restoration sites using pack stock.
3) Temporarily install bear boxes at restoration sites at the beginning of each season, packing them out at the end of the season.
4) Conduct experimental translocations including augmenting two existing translocation sites and conducting one new translocation.
5) Transport translocated frogs by helicopter.
6) Treat frogs prior to translocation with antifungal drug Itraconazole followed by experimental bioaugmentation with naturally occurring bacteria, Janthinobacterium lividum.
7) Continue long-term monitoring at approximately 130 sites annually and approximately 450 sites during summer 2012. Park staff will tag and swab individuals at 13 long-term mark-recapture sites, and temporarily installing one digital recording device at each of two sites.
8) Salvage egg masses and tadpoles from populations threatened by drought.
This project would occur over the next five years, ending in December 2016.
