<br />GUIDE FOR RATING RANGE TREND <br /> <br />Consideriny [he potential for this site, class of livestock, season or use, <br />recreational use, fire, and other influences, rate the following by giving <br />each item a rating of 4 to 0. Interpolate between indicators for ratings <br />3, 2, and I. <br />Trend Indicators <br />REPRODUCTION: <br />Major species of the po[enti,sl plant community are producing <br />seedlings, plants are of mixed ages; there is evidence of <br />active tillers, rhizrxnes, stotons ............................ (;) <br />Major species no[ reproducing ................................ (0) <br />PLANTS RESIDUE AND CURRENT UTILIZATION: <br />Litter produced by major sper.ies is abundant for the Sit: <br />and current utilization is moderate .......................... (4j <br />Litter is absent and utilization is severe ................... (O) <br />COMPOSITION CHANGES: <br />Dominant species of the potential plant community are <br />maintaining their place In the stand ......................... (4) <br />Dominant species are absent or noticeably decreasing in <br />percentage, while minor species and species not native to <br />the community are increasing ................................. (0) <br />PLANT VIGOR: <br />Major species of the potentiail plant community are strong, <br />healthy, productive and we 11 rooted .......................... (4) <br />Major species are showing noticeable die-off ................. (0) <br />SOIL SURFACE FACTORS: <br />Accelerated soli erosion is not evident. Past erosion signs <br />have healed. Water intake for the kind of soil is favorable.. (4) <br />Accelerated erosion is pbvious. Soil stability is poor as <br />seen by failure of erosion signs to be healing. Mater <br />~ <br />intake for the kind of soil is <br />unfavorable ...................
