Weed Management Plan March 2021 <br /> 2.0 Description of Survey Area <br /> Vegetation on the property is dominated by partially irrigated pasture lands, which are <br /> subjected to an inconsistent and uneven application of irrigation water via flood irrigation <br /> and subsurface seepage. Other community types on the property include sagebrush <br /> shrublands (dominated by basin sagebrush (Artemisia tridentata sbsp. tridentate), areas of <br /> greasewood shrublands (Sarcobatus vermiculatus), and expansive wetlands.
