Through improved irrigation <br />systems (i.e. underground pipe, concrete lined ditches, gated <br />pipe and drip type irrigation systems) as well as improved <br />drainage systems and irrigation water management on fields, a <br />loss of wildlife habitat is expected to occur. <br /> <br />Due to overirrigation; areas within and below fields are <br /> <br />often invaded by hydrophytic species such as sedges (carex spp.) <br />and rushes (Juncus spp.), cattail (Typha latifolia)', bulrush <br />(Scirpus spp.), reed canarygrass (Phalaris arundinacea), common <br /> <br />/\~ <br />'i;,> reed (Phragmites communis), saltgrass, willow (Salix spp.), <br /> <br />chickory (Cichorium intybus), and plantain (Plantago spp.) to <br /> <br />mention a few. These areas are classified as irrigation induced <br /> <br />type 1, 2, 3",6, 9, and to a lesser degree type 4 wetlands <br />according to Circular 39 (USFWS). For this report wetlands will <br />be classified according to U. S. Fish and Wildlife Service <br /> <br />circular 39, 1956. <br />Wetland (as that mentioned above) and upland vegetation <br /> <br />(shrubs, trees, and annual and perennial forbs and grasses) <br />associated with on-farm earthen ditches and field borders <br /> <br />(uncultivated areas) are also of concern in terms of wildlife <br />habitat. Off-farm irrigation water conveyance systems which also <br /> <br />support upland, riparian and wetland vegetation provide valuable <br />wildlife habitat. Interspersion of these habitat types with <br />
