communities, community pathways, transition and/or restoration pathways will <br /> be discussed in more detail in the plant community descriptions following the <br /> diagram. <br /> Increased Bare Ground Community <br /> This plant community develops with heavy continuous grazing and/or <br /> occupation by prairie dogs. Red threeawn is the dominant species with sand <br /> dropseed and ring muhly present in small amounts. Blue grama may persist in <br /> localized areas. Pricklypear cactus and fringed sage may increase. Introduced <br /> annuals such as kochia and Russian thistle are present. Introduced species <br /> such as field bindweed can also be present, especially on prairie dog towns. <br /> Litter levels are extremely low. Erosion is evident where flow paths are <br /> continuous. Rills may occur on steeper slopes. Wind scoured areas may be <br /> apparent on knolls or unprotected areas. Plant pedestals caused by wind <br /> scouring are common. The nutrient cycle, water cycle and overall energy flow <br /> are greatly impaired. Organic matter/carbon reserves are greatly reduced. <br /> This community is not stable. Desertification is obvious. <br /> Total annual production can vary from 50 to 200 pounds of air-dry vegetation <br /> per acre and will average 100 pounds during an average year. <br /> Plant Growth Curve <br /> Growth curve C06707 <br /> number. <br /> Growth curve Warm-Season Dominant; MLRA-676; upland fine-textured soils. <br /> name: <br /> Growth curve <br /> description: <br /> Percent Production by Month <br /> Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec <br /> 0 0 0 3 20 45 20 10 2 0 0 0 <br />
