cover (29 percent). The only other morphological class represented was annual forbs at a low <br />0.3 percent cover. Of all species encountered in cover sampling, Kentucky bluegrass (Poa <br />pratensis) had the highest cover and second highest frequency at 21 percent and 87 percent, <br />respectively. Buckhorn plantain followed closely with the second highest cover (14 percent) <br />and highest frequency (93 percent). Other important species were orchardgrass (Dactylis <br />glomerata) at 9 percent cover (67 percent frequency), white Dutch clover (Trifolium repens) at <br />9 percent cover (80 percent frequency), timothy (Phleum pratense) at 3 percent cover (60 <br />percent frequency), dandelion (Taraxacum officinale) at 3 percent cover (53 percent <br />frequency) and red clover (Trifolium pratense) at 2 percent cover (47 percent frequency). A <br />summary of the individual transect data is presented in Attachment 2.04.10 -6 (formerly <br />Peabody 10 -2 (Table 2 -1)). Total annual production for the type was estimated at 2,822.6 <br />pounds /acre (Table 2.04.10 -6). Indicative of the highly variable nature of the type, production <br />estimates from the sample plots ranged from 230 pounds /acre to 8,994 pounds /acre. This <br />large variation was due to the amount and timing of irrigation water application, the amount of <br />supplemental water received which was incidental to the regularly applied amount, and the <br />intensity and duration of grazing prior to the placement of range cages. As an example, <br />sample 2 was dominated by Kentucky bluegrass and buckhorn plantain (Attachment 2.04.10 -6, <br />formerly Peabody Appendix 10 -2, Table 2 -2)). Both require supplemental water to be present <br />and survive in the arid Nucla area and both are dominant in irrigated pasture in the study area. <br />August 2013 (PR 08) 2.04.10 -29 <br />
