奥基山本地植物公司(RMNP)位于科罗拉多州的里弗尔。RMNP生产和安装来自各种生境的本地植物材料，用于修复项目和需要耐寒的本地植物材料的园林美化行业。目前，我们种植了超过2 500000种原生植物，代表大约250个不同的物种。我们繁殖的两个最具挑战性的物种是单籽刺柏(Juniperus monosperma Engelm.)萨格。[柏科])和犹他州刺柏(Juniperus steosperma(Torr)Little)。犹他州刺柏和松树(Pinus edulis Engelm.[松科])形成了遍布美国西部大盆地和科罗拉多盆地的广泛的松柏林地。犹他州刺柏的分布范围很广，从蒙大拿州南部和爱达荷州到加利福尼亚州以及墨西哥的杜兰戈州和奇瓦瓦州。在松柏林地和邻近的科罗拉多州南部、新墨西哥州、俄克拉何马州、得克萨斯州西部和亚利桑那州北部的沙漠草原上也发现了一种独生子刺柏。这两个物种都是长寿的，耐旱的，居住在年平均降雨量在25到37.7厘米(10到15英寸)的地区。这些树种的主根延伸到土壤深处(4.5米[15英尺])，侧根可以延伸到距离树木30米(100英尺)的地方。它们还在树的底部和侧根上发育细根，因此它们在防止干旱荒漠土壤R的风蚀和片蚀方面具有重要作用。
ocky Mountain Native Plants Company (RMNP) is located in Rifle, Colorado. RMNP produces and installs native plant materials from a wide range of habitats for restoration projects and for the landscaping industry, which demands hardy, native plant materials. Currently, we are producing more than 2 500000 native plants representing approximately 250 different species. Two of the most challenging species that we propagate are oneseed juniper (Juniperus monosperma Engelm. Sarg. [Cupressaceae]) and Utah juniper (Juniperus osteosperma (Torr) Little). Utah juniper and pinyon pine (Pinus edulis Engelm. [Pinaceae]) form the extensive pinyon-juniper woodlands throughout the Great and Colorado Basins of the western US. Utah juniper has a broad range, being found from southern Montana and Idaho to California and the states of Durango and Chihuahua, Mexico. Oneseed juniper is also found throughout the range of the pinyon-juniper woodlands and in the adjacent desert grasslands of southern Colorado, New Mexico, Oklahoma, western Texas, and northern Arizona. Both species are long-lived, drought tolerant, and inhabitants of regions that have annual precipitation averaging from 25 to 37.7 cm (10 to 15 in). These species have taproots that extend deep into the soil (as far as 4.5 m [15 ft]) and lateral roots that may extend as far as 30 m (100 ft) from the tree. They also develop fine roots at the base of the trees and on the lateral roots, thus they are important in the prevention of wind and sheet erosion of dry desert soils R
