Abstract

By determining the environmental factors affecting the plant species in a particular site, the presence of the species in a site can be predicted, or indirectly, the environmental conditions in a site can be found by species presence. The aim of this research was to study the response of Buxus hyrcana Pojark to some environmental variables individually and to extract its ecological Optimum and amplitude in relation to the most important environmental factors by using HOF function. This study has been done in the major sites of Buxus hyrcana in the Hyrcanian forests. 834 sample plots (400 m2) were established by systematic-selective method and within each plot, the presence of this species, topographic factors (altitude, slope and aspect) and some soil variables (soil texture, nitrogen, carbon and pH) were recorded and measured. Fitting the Response curve to the environmental variables with HOF function showed that pH, altitude, and clay were the most important predictors on the performance of box tree. The results of this study showed that the Response curves of Buxus species relative to the elevation and clay are unimodal and right-skewed, for sand variable, it is left-skewed, for nitrogen the curve is symmetric and for the remaining variables, the response are monotonically increasing or decreasing. The general conclusion based on the ecological Optimum amount for each variable showed that the Buxus tree is lime-and moisture-demanding species, which is present in low altitudes, steep slopes and light soils with high nitrogen content. Since more than one factor affects the behavior of species simultaneously, it is recommended that the shape of the Buxus Response curve is studied by taking into account the environmental variables in combination and by using other models.
