I <br />~ezetative S-,L*wey for Dorcaester Colorise Coal (coat.) Pace _2. <br />This raze site has a mid grass aspect xith grass height of 6 to <br />15 inches. <br />The gravel breaks - P-J xoodland transition varies xidely, depending <br />an aspect. the south-facing slopes have a dominant plant cor_atmity <br />of Camaels oak on the upper half. 1!ountain mahogany and skunkbush <br />are present in small amounts. <br />Pinyon and juniper range from 8 to 15 feet high and along xith shrubs, <br />5-12 feet, co.-pose 60 to C•5 percent of the vegetation canopy. ?'.idgrasses, <br />6-18 inches, represent the understory canopy. 14.ronty to sixty foot <br />?onderosa pines are fo~md in scattered clumps or individually an the site. <br />°lne grams is the dominant w~derstory grass on the crest of the terraces <br />and again on the toe slopes. Sideoata grams produce small amounts of <br />forage. Little 3luestem, +eatern xheatgrass, bluegraases, cheatgrass, <br />threeaxn aid sedge occur is small amounts. 3uckvheat, yucca, snakexeed, <br />groundsel were the primary forbes. Oroind cover varies from 0-10¢ be- <br />cause of exposed Qravel areas. Total annual production is estimated to <br />• be $00 pow~ds per acre air dry forage. <br />Tne Wort;-facing slopes have a higher percentage of ?inyan pine. Gambels <br />oak is no longer the domiravt ~nderstory shrub, as nowntain mahogany occurs <br />in equal or greater density. ~destern xheatgrass and sideoats grams re- <br />place blue grams as the dominant ~derstory grass. Little bluestem and <br />native bluegrasses also Increase in occu~nce and omduction. Percent <br />ground cover varies from 0 to 15 percent estimated forage production is <br />estimated to be 3~0-5008 greater than production om south slopes. <br />Carrying capacity for cattle may be 1~ to 5 scree per animal snit per <br />month for the range is the permit area. An emi.aial unit is defined here <br />as a mature cow and calf up to six months old. An AlIIi is the.ampunt of <br />torage required for one animal unit far one month. One thousand pounds <br />per AU is generally need. Based an total usable forage for any animal <br />wit, carrying capacity may be estimated. Range producing 11~ pounds <br />per acre s+ith 90 percent total usable forage rill support one anima]. <br />m~it, one cow ~d calf or Sion mule deer for one month. <br />x_40 <br />
