Elk Migration Lines - Egg Lake - 2001-2002, 2017-2020 [ds2907]
Listed in California Open Data
The project leads for the collection of this data were Erin Zulliger and Richard Shinn.
Description
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.
