• though the topography tends to be relatively gentle. Vegetation in these areas consists of a <br />variety of annual and perennial exotic species, as well as remnant examples of the native plant <br />populations. Dominating the vegetation are large native and exotic shade trees, as well as <br />ornamental and exotic shrubs. A detailed survey for herbaceous species was not conducted in <br />the farmstead areas because of the numerous garden, ornamental, and other exotic species <br />normally found in these areas and the fact that these areas will be reclaimed as irrigated <br />pasture. <br />Two abandoned orchards occur within the study The dominant species in these orchards is <br />apple (Malus sylvestris), with peach (Prunus persica) and apricot (Prunus armeniaca) also <br />occasionally present. The orchards were established by Johnson and Morgan mostly for family <br />consumption and are located adjacent to the farmsteads. The trees still yield fruit but are no <br />longer managed for fruit production. The understory is predominated by herbaceous species <br />such as orchard grass, smooth brome, Kentucky bluegrass, quackgrass, plantains, and <br />dandelion. <br />Disturbed areas, a rather self descriptive term, included areas with heavy animal <br />• concentrations, mechanical disturbance due to equipment operation, trash dumps, homestead <br />coal mining, and waste ground associated with various agricultural and support activities. <br />Ponds and irrigation ditches of various capacities are scattered throughout the study area. A <br />large lateral ditch (West Lateral CC Ditch) runs through the study area, while several smaller <br />lateral ditches deliver water to the various irrigated fields, pastures and hay fields in the study <br />and permit area (see Section 2.04.7, Hydrology Description). The vegetation in or near these <br />ditches is dominated by many of the species that occur in the Swale and irrigation pasture <br />vegetation types. Cottonwoods, box elder, cattails, and willows are prominent components of <br />the vegetation associated with these ditches, while the dense cover of graminoid and <br />occasional forb species protect the banks of the ditches from erosion. A total of 9 ponds occur <br />within the study area. Ponds are maintained to catch irrigation and storm runoff water for <br />livestock use. All operators stated that the ponds were not associated with any irrigation <br />systems or water storage for that purpose. The vegetation around these ponds is similar to <br />that found in the Swale type and along the irrigation ditches. <br />(REVISED 9/99) 2.04.10 - 90 <br />
