<br />EXHIBIT J -VEGETATION INFORMATION <br />Present vegetation types <br />Ecotone Corporation and Plantae Consulting Services prepared a "Wetland Finding Report" for this <br />property. Their description of existing vegetation follows. <br />The majority (89.2%) of the property comprises upland areas primarily used for agricultural <br />purposes including pasture, hay production and row crops. The hay field areas aze dominated by <br />pasture grasses such as fescue, smooth brome, bluegrasses, orchard grass and timothy. Where <br />upland areas are grazed by cattle, native grasses such as western wheatgrass, Canada wild rye and <br />bentgrass occur with the pasture grass species. These grazed areas also tend to support a <br />complement of noxious weeds, including diffuse knapweed, yellow toadflax, Dalmatian toadflax, <br />cheatgrass, Canada thistle, mullein and houndstongue. <br />The wooded portion of the site supports a canopy dominated by plains cottonwood trees. Less <br />common canopy trees include crack willow, Russian olive, green ash, black locust and Chinese elm. <br />The forest understory is composed of the native and pasture grasses described above. Some <br />understory areas also support a number of the previously listed weeds. <br />Relationship ojpresent vegetation types to soils types <br />According to the United States Department of Agriculture Soils Conservation Service's Soi! Survey <br />ojBoulder Countv.9rea, Colorado (issued January 1975), the best-suited vegetation for each soil <br />type is as follows: <br />Niwot Soils (Nh) <br />This soil is best suited for use as pasture or meadow due to high water table and the depth to <br />sand or gravel. In some small areas may be used for irrigated crops. <br />Nunn Clay Loam (NuB) <br />This soil type is used £or irrigated crops and pasture as well as dryland crops. <br />Loveland Soils (Lv) <br />This soil type is suitable for irrigated crops or pasture. <br />Terrace Escarpments (Te) <br />Terrace Escarpments are not suited to cultivation. It is used for native range. <br />Valmont Clav Loam (VaC) <br />This soil type is used for irrigated and dryland crops and for pasture. <br />Nunn-Kim comnlex (Nv) <br />This complex is used for irrigated crops and pasture. <br />These soil types are delineated on the Existing Conditions Map. <br />AGGREGATE INDUSTRIES, INC. - FREDSTROM SITE 112 PERMIT PAGE -39- <br />
