desired results of heavy stocking are realized, the stocking rate in following grazing <br />seasons will be adjusted downward to the proper use factor of approximately 50@ forage <br />utilization. <br />Forage utilization will be monitored by comparing the amount of unused forage in range <br />utilization cages located in the pasture. The following table will be used as the initial <br />stocking rate guide. <br /> ~ Utilization of Forage <br />SO@ (normal) 65~ 75@ (heavy) <br />Crazing 1 month 1.7 AU's/Ac. 2.2 AU's/Ac. 2.5 AU's/Ac. <br />Season 3 months 0.6 AU's/Ac. 0.7 AU's/Ac. 0.8 AU's/Ac. <br />5 months 0.3 AU's/Ac. 0.4 AU's/Ac. 0.5 AU's/Ac. <br />Note: 1 AU (Animal Unit) = a 1000 lb mature cow or a cow-calf pair <br />.80 AU = cattle, 2 years of age <br />.60 AU = cattle, 1 year of age <br />.20 AU = sheep, mature <br />.15 AU = lamb, 1 year of age <br />Pasture = 303 acres <br />Two kinds of livestock, cattle and sheep, will be considered for grazing in the management <br />areas. Classes of livestock (i .e. mature cows, bulls, heifers, steers, ewes, weaned lambs <br />or rams) will not be specified. Incidental use by elk and deer will also occur in the <br />management areas. <br />The general period for grazing is from mid-May through the end of October. Exact time <br />frames for grazing seasons will depend on weather conditions in a given year, livestock <br />availability, the overall grazing program of the operator chosen by Peabody and the <br />management requirements relating to vegetation manipulation and grazing intensity. <br />Turn-in and turn-out dates will be specified to the livestock operator prior to the <br />grazing season, taking into account the individual's operational needs. On-site <br />management contact and coordination with the operator wilt be through the Seneca II Mine <br />Reclamation Supervisor. <br />13-4-3 <br />
