Mule Deer Migration Lines - Modoc Interstate CA and OR - 1999-2001, 2017-2020 [ds2893]

Description

The project leads for the collection of this data were Julie Garcia and Richard Shinn. Female mule deer were captured in February 2017 and equipped with satellite collars manufactured by Lotek, which collected GPS data to June 2020. Additional GPS data was collected from deer in 1999-2001 and included in the analysis to supplement the small sample size of the 2017-2020 dataset. The data was collected from deer throughout Modoc County with a priority to ascertain general distributions, survival, and home range and not to model migration routes, hence the low sample sizes in specific winter ranges. The Modoc Interstate deer herd migrates from a winter range near Clear Lake Reservoir in Modoc County, California north into Oregon in Klamath and Lake counties for the summer. GPS locations were fixed at 12-hour intervals in the 2017-2020 dataset and 8-hour intervals in the 1999-2001 dataset. Migration lines as symbolized connect GPS data points per deer per seasonal migration. GPS points were extracted only during migrations using net-squared displacement graphs. Sixteen migration sequences from 12 deer, with an average migration time of 23.89 days and an average migration distance of 69.71 km, were obtained from the 1999-2001 dataset. Thirty-six migration sequences from 9 deer, with an average migration time of 19.53 days and an average migration distance of 87.57 km, were obtained from the 2017-2020 dataset.
