A comparison of vegetative climate of Artemisia sieberi Besser and Artemisia aucheri Boiss in Iran

The relationship between plant species and climatic factors has always been a fundamental issue in ecology, the use of multivariate statistical methods can be effective revealing distribution. Therefore, this study, affecting distribution Artemisia sieberi aucheri, widely distributed Iran, were investigated. For purpose, 117 used, to reduce number determine most important ones, factor analysis was used by principal component analysis. results showed that six including heating temperature, spring summer precipitation, wind, autumn–winter dusty cloudiness days explained 37.32%, 22.54%, 7.18%, 6.6%, 4.22%, 4.15% data variation, respectively. Together these seven account for 82% variation. precipitation temperature had greatest impact on presence respectively, so negative areas where Ar.sieberi is observed. Ar.aucheri present, while it positive lacking Ar.aucheri. study effect environmental very planning management natural resources, one plants country’s rangelands; therefore, research practical planning, management, reclamation rangelands.
