Summary of estimated home range sizes (in ha) for adult Mojave desert tortoises in the greater Ivanpah Valley Area. Estimates were made using autocorrelated kernel density estimators in R package ctmm. Tortoises that encountered fences are included in a separate row. Minimum and maximum values are not displayed when only one tortoise from a site had sufficient data for that year
