Weather conditions, rainfall, soil, and ripeness are the main determinants of vegetation cover. Precipitation is the main variable in determination of vegetation in Lorestan province. With the exception of the northern strip of the province, which is largely arable and pasture land, other areas of the province are often covered with forest cover. The surface of Lorestan forests is about 750 thousand hectares. The combination of these forests is different from the altitude, latitude, rainfall, compression of mountains, roughness, and the length of the cold season or the warm season.
Vegetation density is more in the spring, because sometimes severe winter colds or, in some cases, rainfall shortages and increasing summer heat causes the vegetation to dry out and disappear.
