AB  - In order to investigate the role of climatic elements on the distribution of range species of
<I>Gymnocarpus decander</I> in the Northen Persian Gulf region, three habitats in each rangeland of these region
were selected and using strip transect and plot methods were calculated the density and percent of
<I>G. decander</I>’s canopy. Climatic factors such as temperature, precipitation, relative humidity, wind speed,
sunshine clock and evaporation pan in stations of each area were collected, climatic factors and plant factors
(density and canopy percent) were considered respectively as independent variable and dependent variable
and were analyzed using SPSS. The results of Kolmogorov-Smirnov test showed that the climatic and plant
factors in province have a normal distribution. Then, to identify the most important climatic parameter affecting
the distribution of range species of <I>G. decander</I> in the northen Persian gulf region, a matrix with dimensions
of 90*14 was prepared through climatic and plant data, the matrix is composed of fourteen climatic elements.
The factors were reduced to three main factors using factor analysis technique and were rotated using varimax
rotation. Factor analysis technique which reduced factors to three main factors was done for eigenvalues &lt;1.
Generally, the temperature factor has the most important impact on the distribution of range species of
<I>G. decander</I> in the North Persian Gulf region.
