Elk Home Range - Lone Pine - 2023-2024 [ds3192]
Listed in California Open Data
The project lead for the collection of this data was Carrington Hilson.
Description
Elk (2 adult females) were captured and equipped with GPS collars (Lotek Iridium) transmitting data from 2023-2024. The Lone Pine herd does not migrate between traditional summer and winter seasonal ranges.
Therefore, annual home ranges were modeled using year-round data to demarcate high use areas in lieu of modeling the specific winter ranges commonly seen in other ungulate analyses in California. GPS locations were fixed at 6.5 hour intervals in the dataset. To improve the quality of the data set, all points with DOP values greater than 5 and those points visually assessed as a bad fix by the analyst were removed.

The methodology used for this migration analysis allowed for the mapping of the herd's home range. Brownian bridge movement models (BBMMs; Sawyer et al. 2009) were constructed with GPS collar data from 2 elk, including 2 annual home range sequences, location, date, time, and average location error as inputs in Migration Mapper. BBMMs were produced at a spatial resolution of 50 m using a sequential fix interval of less than 27 hours and a fixed motion variance of 1000.
Home range is visualized as the 50 th percentile contour (high use) and the 99 th percentile contour of the year-round utilization distribution. Home range designations for this herd may expand with a larger sample.
