If a solid early storm rolls in, they can come streaming out of the high country, sometimes moving as much as 12 miles in a single day. This migration strategy allows individuals to maximize their annual nutritional intake, providing great forage that underpins higher survival and reproductive rates. (2010), the GPS data were filtered prior to analysis to remove locations which were: i) further from either the previous point or subsequent point than an individual deer is able to travel in the elapsed time, ii) forming spikes in the movement trajectory based on outgoing and incoming speeds and turning angles sharper than a predefined threshold , or iii) fixed in 2D space and visually assessed as a bad fix by the analyst.The methodology used for this migration analysis allowed for the mapping of winter ranges and the identification and prioritization of migration corridors in a single deer population.
