California Department of Fish and Wildlife 20210120 vector digital data https://www.wildlife.ca.gov/Data/BIOS http://ftp.dfg.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/2900_2999/ds2907.zip The project leads for the collection of this data were Erin Zulliger and Richard Shinn. Elk (6 adult females, 3 juvenile males, and 2 juvenile females) were captured in 2017 and equipped with Lotek satellite GPS collars or VHF tags, transmitting data from 2017-2020. Additional GPS data was collected from elk (6 females) in 2001-2002 and included in the analysis to supplement the small sample size of the 2017-2020 dataset. The Egg Lake elk herd migrates from a winter range surrounding Egg Lake in Modoc County, California eastward into Siskiyou County for the summer. GPS locations were fixed at 4-hour intervals in the 2017-2020 dataset and 3 to 8-hour intervals in the 2001-2002 dataset. Migration lines as symbolized connect GPS data points per elk per seasonal migration. GPS points were extracted only during migrations using net-squared displacement graphs. Nine migration sequences from 5 elk, with an average migration time of 6.78 days and an average migration distance of 26.83 km, were used from the 2000-2001 dataset. Fourteen migration sequences from 6 elk, with an average migration time of 7.79 days and an average migration distance of 42.40 km, were used from the 2017-2020 dataset. Migration line locations for Rocky Mountain elk (Cervus canadensis nelsoni) developed by the California Department of Fish and Wildlife (CDFW) for the Egg Lake herd, Modoc and Siskiyou counties, California. Migration lines were developed in Migration Mapper using GPS locations from collared elk.

Prior to using this dataset, please contact Kristin Denryter, Erin Zulliger, or Richard Shinn to ensure correct interpretation of the data. The sample only represents a small fraction of the possible population of elk migrating in this area; therefore, other migration routes may have gone undetected in our analysis. This analysis represents migration routes from one elk herd, one study, and is one of a suite of datasets being developed for California’s ungulate herds by CDFW.CDFW makes no warranty of any kind regarding these data, express or implied.
