Abstract

TAXUS BACCATA populations in Iran are limited to the forests on north slopes of Elborz mountain (South of Caspian Sea). These trees are sporadically distributed throughout Guilan and Mazindaran provinces, with more concentration in Shaft and Foman region (Guilan province) and pure stands in Afratakhteh and Siarudbar (Mazindaran province) (Mossadegh 1972, Habibi and Lessani 1986). Shaft and Foman populations have not been studied very well, and the data is very limited. These populations are mainly located in 49, 21" longitude and 37, 12" latitude. They are growing at 700-1200 meters above sea level with average annual precipitation of 1357 mm. The soil in this region is mildly acidic. Trees are scattered throughout this region as individual clumps. Afratakhteh and Siarudbar populations are located between 54, 54" -55, 7" longitude and 36, 46" - 36, 50" latitude, with mean annual precipitation about 1140 mm. The average tree height in these pure stands is about 18.8-23.8 meter with maximum height of 30 meters. The average diameter is between 36-41 cm. Trees with 110 centimeters in diameter has also been observed (Mossadegh 1972). Based on dendrological studies, the average age of trees in these populations is estimated between 500-800 years (Habibi and Lessani 1986). Thousand year old trees has also been recorded (Mossadegh 1972). In a study by Mossadegh (1972) total number of trees per hectar were 610 of which 529 were T.baccata. Total basal area of trees were 75 m2. T. baccata in Iran, Turkey and Kasakestan is classified to be associated with Rhus plant community as a sub-division of fagetum hyrcanum taxetum. However, in Afratakhteh there are very few Fagus orientalis, and thus cannot be classified in Fagetellia. It also cannot be classified in Aceretum community, due to low humidity. However Evonymus latifolia occurs only with T.baccata. Thus Mossadegh (1972) have renamed the Afratakhteh population to Evonymo- Taxetum. Seed production in Iranian populations alternates every 2 to 3 years. Most of the seeds are infected or eaten by variety of insects. Thus regeneration is very poor in these stands. Heavy grazing, and improper logging by local people also contributes to this condition. Grazing on re-sprouted stumps have been observed numerous times. Three soil type were found in Affatakhteh and Siarudbar (humic, brown calcareous colluvial and brown calcareous). All of these are rich in organic matter and calcium. They are often gravelly with PH between 6.5-7.5 (Habibi and Lessani 1986).
