Chapter 2. Vegetation of the Upper Gunnison Basin
Chapter 2. Vegetation of the Upper Gunnison Basin In the Upper Gunnison Basin, as in many other Daubenmire (1943-1944), although some scientists parts of the Rocky Mountains, vegetation appears have called them “belts” (Löve 1970). The different at different elevations. These are called vegetation zones that are usually used are shown in vegetation zones by Rydberg (1917) and Figure 2-1 and Table 2-1. 13,000 3,920 12,500 3,770 12,000 3,620 11,500 A 3,470 11,000 3,320 10,500 3,170 10,000 S 3,020 9,500 2,870 t f 9,000 2,720 m n, n, o 8,500 2,570 i o i at 8,000 2,420 at v v e l 7,500 2,270 e MS l E 7,000 2,120 E 6,500 M 1,970 6,000 1,820 5,500 1,670 5,000 F 1,520 4,500 1,370 4,000 1,220 3,500 F 1,070 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 Latitude, °N Fig. 2-1. Elevational boundaries between zones in the Rocky Mountains (after Daubenmire 1944, Gregg 1963, Marr 1964, Cronquist and others 1972). A = Alpine Zone, S = Subalpine Zone, M = Montane Zone, F = Foothills Zone. MS = Mountain Shrub. The double arrows show the elevational range of piñon-juniper. Table 2-1. Life zones and vegetation used by various workers (adapted from a table in Gregg 1963). Plant species names are explained in Appendix A.
