_.. <br /> <br />/ EXAMPLE CARRYING CAPACITY CALCULATION <br />Objective: Estimate winter carrying capacity of south facing mountain shrub <br />habitat for deer based on energy supply. <br />I. Range Supply Calculations (to convert kg/ha to pounds/acre, multiply kg/ha <br />by 0.9) <br />A. Food habits in mountain shrub: browse stems and leaves, forbs, green <br />grass. <br />B. Food quantity <br />browse = 150 kg/ha <br />forbs = 50 kg/ha <br />green grass = 5 kg/ha <br />C. Availability <br />100% of browse = 150 kg/ha <br />50% of forbs = 25 kg/ha <br />100% of green grass = 5 kg/ha <br />D. Allowable use <br />50% of browse x 150 kg/ha = 75 kg/ha <br />75% of forbs x 25 kg/ha = 18.7 kg/ha <br />100% of green grass x 5 kg = 5 kg/ha <br />E. Food quality <br />browse = 1150 kcal/kg <br />forbs = 1530 kcal/kg <br />green grass = 2500 kcal/kg <br />F. Energy supply <br />browse = 1150 kcal/kg x 75 kg/ha = 86250 kcal/ha <br />forbs = 1530 kcal/kg x 18.7 kg/ha = 28611 kcal/ha <br />green grass = 2500 kcal/kg x 5 kg/ha = 12500 kcal/ha <br />total =127361 kcal/ha <br />II. Energy Requirements <br />A. Average body weight = 65 kg <br />B. Energy costs <br />resting energy requirements = 100 x 650'75 = 2289 kcal/day <br />thermoregulation requirements = 0.25 x 2289 = 572 kcal/day <br />activity costs = 2 x 2289 kcal/day = 4578 kcal/day <br />C. Time budget <br />resting = 12 hr <br />acting = 12 hr <br />D. Overwinter requirements <br />1. length of winter = 180 <br />number of days with minimum temp below - 5F = 40 <br />
