In 1999, estimates of mean cover in 2 subjectively selected irrigated pastures (deemed representative of "typical" conditions) were also similar, showing perennial grass cover of 44.5%, perennial forb cover of 33.3%, and total desirable vegetation cover of about 79%. Annual herbaceous production was estimated at 4,153 lb/acre. The 1999 mean is higher than the 2007 mean measured in the reference area, but the irrigated pasture type has been demonstrated in 1987 and 1999 sampling to be extremely variable in production depending on site factors, management, and maintenance. The site has been inspected by the NRCS and found to be acceptable as a reference area. Reference Area Management The water in this reference area and all mine reclaimed areas is from the same ditch of the CCC Ditch Company, thereby eliminating any differences in water availability during the year. The contractor will be required by New Horizon to apply the water to the reclaimed areas and the reference area at the same time. New Horizon owns the reference area and is in charge of the irrigation management of it. The contractor will release water into the reclaimed area and the reference area from the CCC Ditch at the same time. The flood irrigation of the reference area will be regulated to simulate the same plant application rate and conditions of the side roll irrigation of the reclaimed area. Flood irrigation may also be employed in the reclaimed area. The expected application rate of water will be based on the ratio used for the irrigation of Irrigated Pasture on the Lloyd property. Plans for grazing and/or haying will be conducted on the reference area based on the needs of reclamation and vegetation studies. During vegetation study years, grazing and/or haying will not be conducted until the vegetation studies are complete. The first cut in the area is typically by the end of June. Vegetation studies will be completed by this point to allow grazing and/or haying to be conducted. Both the reference area and the reclaimed area may be hayed and/or grazed. Fertilizers may be applied to the reference area and the reclaimed area but must be done at the same time and the same rate per acre on both areas. The application rate will be similar to normal practices in the surrounding area for Irrigated Pasture. The contractor will be instructed that this practice must be followed. Fertilizer may not be applied every year. It will be applied at the frequency that is normal good practice for the area and the soils. Page 20 May 2016 (TR -75)
