Soil Information for All Uses <br /> Ecological Site Assessment <br /> Individual soil map unit components can be correlated to a particular ecological site. <br /> The Ecological Site Assessment section includes ecological site descriptions, plant <br /> growth curves, state and transition models, and selected National Plants database <br /> information. <br /> Ecological Site Information for: <br /> R067BY024CO — Sandy Plains <br /> R067BY024CO — Sandy Plains— <br /> Reference Plant Community <br /> This is the interpretive plant community and is considered to be the Reference Plant <br /> Community. This plant community evolved with grazing by large herbivores, and is <br /> well suited for grazing by domestic livestock. It can be found on areas that are <br /> properly managed with prescribed grazing that allows for adequate recovery periods <br /> following each grazing event. The potential vegetation is about 70-85% grasses and <br /> grass-like plants, 10-15% forbs, and 5-15%woody plants. <br /> The dominant tall warm season grasses are prairie sandreed, sand bluestem and <br /> switchgrass. Blue grama dominates the understory. Important cool season grasses <br /> and grass-likes are needle and thread and sun sedge. Key forbs and shrubs are <br /> American vetch, pacific peavine (manystem pea), purple prairie clover, and <br /> spreading buckwheat. <br /> This plant community is diverse, and productive. Litter is properly distributed with <br /> very little movement off-site, and natural plant mortality is very low. It is well-suited <br /> to carbon sequestration, effective water cycle, and wildlife use by many species, <br /> livestock use, and is aesthetically pleasing.
