<br />Range in Elevation: 5,000 - 7,500 feet - San Luis Valley 8,000-9,000
<br />Precipitation Range: 12 to 15 inches
<br />Average Annual Temperature: 49° - 53° F
<br />Frost Free Period: 60 - 120 days
<br />General Description of the type: 1'he pinyon - juniper type cn,odland occurs at rile
<br />lowest elevations of the coniferous cioorlland. types in Colorado, It is G~c
<br />transition zone between grasslands and the montane ;"Wrests. At t;~c Loucr limits
<br />the type may consist of scattered to almost pure stands of Utali juniper cn file
<br />lJestern slope, and one seeded juniper on the Eastern slope, As the type blends
<br />into the Ponderosa pine or oalcbrush types, pinyon pine and Roclcp 14ountain juni-
<br />per become the dominant species. Between rile extremes pinyon and the various
<br />junipers constitute a true plant association,
<br />Associated Overstory plants: Except for stunted ponderosa pine near the upper
<br />elevations of the type there are no associated trees in the type.
<br />1
<br />Associated Understory plants:
<br />Upper Limits
<br />hlountain mahogany, Indian rice grass, mutton grass, sedges, prarie junegrass,
<br />big sagebrush (west slope), service berry, cliff rose,
<br />Lower Limits
<br />Lndian rice grass, blue grams, galleta, cheatgrass, Fendlcr three acun, Rabbit-
<br />brush, Snakeweed, Fleabane,
<br />Effects of Aspect and Position: At upper limits of type it prefers south and c:r.st
<br />facing slopes. On slopes the density is usually less than on flatter areas,
<br />I•fesa tops, moderately sloping lands, and valley floors usually have more dense
<br />stands,
<br />Site Index: .In site index curves are available for these spucics, •~hile some
<br />stands will reach heights of over 35 feet, ninny stands do not reach over 2(,
<br />feet. Because of the uniformity of the type no site index Trill be used.

<br />Uses of the Species: Junipers are a good source of fence posts, Pinyon pine is a
<br />good fuel wood species and good Cor Chrisunas trees, Some trees on areas nE
