i <br /> • Production <br /> Production data from the 1989 monitoring studies are presented in Tables 11 through 19. Data <br /> are summarized in Table 29, and graphically displayed in Figure 2. <br /> Highest herbaceous biomass production was measured on reclaimed Area D (Wadge Pasture) at <br /> 2152.6 pounds per acre, approximately 85 percent more than the most closely equivalent Wadge <br /> reclamation areas (Areas B and C, 1227.6 and 1238.2 pounds per acre, respectively). The <br /> younger Wadge reclamation in Areas G and H was slightly more productive (1389.2 and 1331.2 <br /> pounds per acre, respectively) than the older ungrazed Wadge reclamation in Areas B and C. <br /> Younger Wolf Creek reclamation (Areas E and F, 956.5 and 988.7 pounds per acre, <br /> respectively) was lower in produced biomass than any other reclaimed areas, still <br /> approximately doubled the herbaceous biomass production of either reference area. <br /> In the 1977 Wadge reclamation (Area B), the bulk of biomass production was comprised of <br /> introduced perennial grasses (519 pounds per acre) and introduced perennial forbs (587 <br /> • pounds per acre, including 169 pounds per acre of alfalfa, 28 pounds per acre of Cicer <br /> milkvetch, and 390 pounds per acre of other introduced perennial forbs). <br /> By contrast, alfalfa, by itself, was the dominant contributor to biomass production in the <br /> 1980/1982 Wadge reclamation (Area C, 517 pounds per acre) and the Wadge Pasture (Area D, <br /> 1085 pounds per acre). Introduced perennial forb production was minor in all other areas, <br /> including the reference areas, while alfalfa has remained a major contributor(but not the <br /> dominant) in all reclaimed areas except the youngest Wadge and Wolf Creek areas (Areas F and <br /> H). <br /> Cicer milkvetch is nowhere more than 1 to 4 %of total biomass production. Introduced <br /> perennial grass production was roughly 1/3 to 1/2 of total production in all reclaimed areas, <br /> except the youngest (1987) Wolf Creek area where it was about 1/5 of total production. <br /> Native perennial grass production was approximately 10 percent of total production throughout <br /> the reclaimed areas, except in the Wadge Pasture (Area D, about 3 percent of total production) <br /> and in the 1985/1986 Wolf Creek areas (Area 5, nearly 30 percent of total production).
