• Spring grazing will reduce reproductive ability of early annual weeds and <br />annual grasses. <br />• Grazing will stimulate plant growth and vigor. Additionally, eazly grazing of <br />the revegetated areas will reduce cool season graminoid representation and enhance <br />development of the warm season grasses in the revegetated community. <br />• Grazing will physically disburse seed, increasing plant distribution and <br />ultimately the ground cover. Vegetative reproduction (tillering) will also be <br />stimulated through grazing. <br />The current grazing plan was approved by CDMG in minor revision 17 (10/1990). A two <br />pasture, switchback, deferred grazing schedule was approved with grazing beginning in <br />May (or following the annual reclamation "field sampling") and ending October 31. The <br />initial stocking rate was three (3) acres per Animal Unit Month (AUM). <br />It should be noted that range management professionals will monitor the approved plan. <br />Grazing will be allowed as long as there is no detriment to the revegetation. <br />Additionally, CEC may temporarily discontinue grazing, based on recommendations of <br />the range management professionals or CEC mine staff in order to protect soil, plant or <br />other resources at the site. <br />. Mowine <br />CEC may employ mowing as a technique to control annual weed growth on newly seeded <br />reclamation areas and, to break up thatch, disperse seed and discourage annual weed <br />growth on established reclamation plots. When used on new areas, it will be planned to <br />catch a majority of the annual weeds in advance of seed maturation. <br />Controlled Bumine <br />Under certain conditions, CEC may employ controlled burning as a means to manage <br />thatch buildup, and to control weeds such as cheatgrass that do not respond well to <br />management through grazing, mowing or other accepted means. Controlled burns will be <br />conducted under the direct supervision and following guidelines of the local fire <br />protection district. <br />Vegetation Monitoring <br />CEC will monitor revegetation that has been planted for three or more growing seasons. <br />Vegetation monitoring will take place at or near anthesis of the dominant plant species in <br />the revegetated and reference areas. Sampling is dependent on several environmental <br />factors (primarily seasonal moisture), but is anticipated to occur between May 15 and <br />• September 30, Monitoring will occur on each planting until such time as success <br />standards for cover, production and diversity have been attained. Monitoring will include <br />115d 04/01 <br />
