Abstract

RANGE CONDITION can be considered as an important indicator of management assessment. Method known as four factors was used to assess RANGE CONDITION each year. Some important communities of Yazd province were selected. In each community a key area was determined. Fifteen key areas were selected in whole province. In each site for every year, SOIL erosion, canopy COVER, plant composition and vigorey of plants were monitored. The result showed no significant difference between above mentioned factors during five years (p> 0.05). However, factors significantly varied between sites in different years. In spite of constant VEGETATION condition trend rainfall varied among years. So marks recorded for each factors during the period of study were compared using principal component analysis and clustering. Sites in terms of condition, VEGETATION COVER and SOIL were classified. Correlation between value of each factor and condition value showed that vigorey had no significant relationship with RANGE CONDITION by these sites. Generally Yazd's rangelands classified in poor to fair condition with constant RANGE CONDITION trend in period of five years.
