CO Mule Deer Unit 143
AI Scout Preview
CO 143 — Tactical Analysis. Terrain & Access CO 143 spans 441,700 acres across elevation from 4,583 to 6,878 ft, encompassing both foothill and mid-elevation habitat. However, only 9.4% of the unit is public land—a significant access constraint. Hunters must plan carefully to identify public parcels and may face substantial walking or need to secure permission on private ground. The elevation band supports mixed timber and open country typical of Colorado's front-range and transition-zone terrain. Herd Quality Recent wildlife surveys indicate a 50:100 buck:doe ratio—above average herd composition that reflects solid fawn recruitment and reasonable sex structure..
