Figure 4-3 and the foreground of Figure 4-4 show grass and clover dominated hayland; Figure <br />4-4 (middleground) shows an alfalfa dominated stand.) <br />Harvest period, number of harvests during the growing season, fertilization programs, and <br />management of the stands after harvest were all different for the various operators. Number of <br />harvests varied from one to three per growing season. This variability reflects different <br />management levels and objectives. <br />Composition of the irrigated pasture hayland type is highly variable depending on the individual <br />operator. Garvey and Goforth have both recently renovated all or parts of their hay fields. <br />These renovated fields are dominated by alfalfa and contain various companion grasses such <br />as orchardgrass and smooth brome. Staats' fields also have a fair alfalfa composition. In <br />addition, desirable pasture grasses are being supplanted by Kentucky bluegrass, quackgrass, <br />meadow fescue (Festuca pratensis), tall fescue (Festuca arundinacea), buckhorn plantain, and <br />dandelion. Burbridge does not manage for alfalfa in his hay fields and does not regularly <br />renovate these fields because of shallow soils and rock ledges. Consequently these haylands <br />are dominated by a variety of desirable and increaser grasses, red and white Dutch clover, <br />weedy forb species and occasional alfalfa plants. <br />5.4 Swale/Drainage Type (IPSW) Flood irrigation of lands on and adjacent to the study area <br />has created water regimes in certain locations that favor the establishment of hydrophytic and <br />phreatophytic vegetation (see Attachment 2.04.10.-5, Figure 4-5, formerly Peabody Appendix <br />10-4). These situations occur where: 1) small natural drainages or swales (with gentle slopes) <br />collect tailwater drainage from the surrounding irrigated fields; 2) shallow ground water, <br />augmented by irrigation, daylights along exposed bedding planes or fractured rock to form <br />seeps and boggy areas; 3) shallow water conditions exist along the borders of ponds and <br />depressions in channels; and 4) stable conditions occur on portions and banks of the two <br />streams draining the study and surrounding area (Calamity Draw and Tuttle Draw). Because of <br />the variation in site specific water regimes within the type, three major components may be <br />delineated. Dense thickets of coyote willow (Salix exigua) occur on shallow, slightly elevated <br />sites along the drainages where better -drained conditions exist (see midground of Figure 4-3, <br />Attachment 2.04.10-8, formerly Peabody Appendix 10-4) or in areas surrounding seeps with <br />similar conditions. Less well -drained areas, or areas where standing or slow -flowing water <br />occurs during much of the growing season, support vegetation that is dominated by <br />February 2015 JR -66) 2.04.10-36 <br />
