This project was initiated by the CDFW Central Region and was conducted on a portion of the Tuolumne herd that migrate to Jawbone Ridge in the winter in Tuolumne county, Mariposa county, and Alpine County. Some individuals from the Yosemite Herd were also captured to help determine herd overlap. 376 samples were taken during the 6 years of this study, and 375 of these samples were captures, whereas 1 was a buck mortality that was found dead and sampled. Individuals were captured via darting or clover traps. 324 of the captures were unique individuals, and the others were re-captures. 260 captures were females (214 unique females), and 116 were males (109 unique males). Along with checking the hair coat, body condition and for lice, the individuals were aged, received body measurements, and their blood was drawn. Fecal pellets were also collected when possible. Transmitters were installed on most captured individuals, but not all: 171 ear tag transmitters, 99 GPS collars, and 22 Telonics VHF collars. The GPS collars were ATS store on board GPS collars (G2110B/D model) and were placed on females only.
This project was initiated by the CDFW Central Region as a response to a big mortality event with deer in the residential area of Pine Mountain Lake in which over 200 deer died from February 4 to June 20, 2009. This study was broken down into 3 phases: phase 1 was to determine the louse species present and their life cycle, what populations were infected, the range of the deer population and its overlap with adjacent deer populations, and gather the baseline information on survival and health on the deer population; phase 2 was to test the impact that the presence of lice has on survival, clinical hair loss, and baseline condition, and mortality; and phase 3 was to test if selenium and copper affect hair loss, louse presence, mortality, and fawn recruitment.
Credits are given to the entities that helped purchase the collars and made the study possible. Prior to others using this data, we would like to be able to complete what we have started. There were quite a few that had some very strange migrations or home ranges. We have all the ranges and migrations plotted and printed and plan to use this for a manuscript. We also have some other uses for defining herds, plotting specific use areas, etc. Although we had great plans to be done by now, our staff have been redirected onto the nutria project, and Nathan took the promotion.The work will be completed, but it is just taking longer than expected. So, any use should be approved. We already have approved use for some of the statewide deer program identification of areas and timing for surveys, etc. Specific requests can be sent to me (Ron Anderson ronald.i.anderson@usda.gov ). Much of this data was collected with other funding, which will need to be recognized. A full list can be provided.
