Migration is driven by necessity for most other species of deer, and if they dont need to move to survive, most other deer species prefer to stay in their native habitat year-round.

Winter range designations for this herd may expand with a larger sample, filling in some of the gaps between winter range polygons in the map. Many ungulate herds in California are migratory and inherently need large landscapes to persist, making them particularly vulnerable to habitat loss and fragmentation. Corridors and stopovers were prioritized based on the number of animals moving through a particular area. Each year there are approximately 4 million births in the U.S. and 2.4 million deaths.
