EXHIBIT J -VEGETATIVE INFORMATION (a) Describe present vegetation types including quantitative estimates of cover and height for the principal species in each life form represented (i. e. trees, tall shrubs, low shrubs, grasses, forbs),~ The majority of the site is actively farmed. The crops are regulazly rotated and include: alfalfa, corn, and pasture. According to Exhibit H which was prepazed by Savage and Savage: "An open canopy of plains cottonwoods (Populus deltoides) dominates the riparian corridor adjacent to the Big Thompson River. This open riparian corridor is dominated by mature cottonwoods with an open graminoid and forb understory. Other scattered trees along the riparian corridor include Russian olive (Elaeagnus angustifolia) and peach-leaf willow (Salix amygdaloides). Dominant undrestory graminoid species consist of western wheatgrass (Agrpyron smithii), inland saltgrass (Distichlis spicata), smooth brome (Bromus inermis), fescue (Festuca sp.), and cheatgrass (Bromus tectorum). Several weedy species also dominated the understory including musk thistle (Carduus nutans), diffuse knapweed (Centaurea diffusa), and tansy mustard (Descurainta pinnata). The remainder of the site is planted to corn." The approximate locations of mature trees and the results of the Savage and Savage wetland delineation are shown on the Existing Conditions Map (Exhibit C). Hall-Irwin will obtain a 404 permit prior to any disturbance of the wetlands. (b) the relationship of present vegetation types to soils types (or may show on map); Please refer to Exhibit C for the locations of the various soil types described below. According to the United States Department of Agriculture Soils Conservation Service's Soil Survey of Weld County, Colorado: Southern Part (Appendix A), (Issued September 1980), the best-suited vegetation for each soil type is as follows: Aguolls and Aquents Native vegetation: alkali sacaton, switchgrass, and western wheatgrass, saltgrass, sedge, msh, and alkali bluegrass; and Seeded vegetation: switchgrass, western wheatgrass, alkali sacaton, tall wheatgrass, and tall fescue. Dacono clay loam Irrigated crops: corn, sugar beets, beans, alfalfa, small grain, potatoes, and onions; Non-irrigated crops: small grain, winter wheat, and spring wheat; Native vegetation: western wheatgrass, blue grama, buffalograss; Seeded vegetation: western wheatgrass, blue grama, sideoats grama, buffalograss, pubescent wheat grass, and crested wheatgrass; Trees: Rocky Mountain juniper, eastern redcedaz, ponderosa pine, Siberian elm, Hall-Irwin Corporation Bernhardt Resource Page 28 of 41 MLRB 112 Pemtit Application
