Abstract

The AFFORESTATION efforts is one of the methods used for ruined land restoration and renovation in the north forests of the country and for this reason the evaluation of each planted species especially local species has a special and great importance. In this study ALNUS SUBCORDATA, ACER VELUTINUM, FRAXINUS EXCELSIOR species from the view point of QUALITATIVE AND QUANTITATIVE attributes were studied in Guilan’s Toutki forests. The inventory was done by systematic-random method in 57, 5R Sample pieces (500 m2) and with an intensity of 5 percent. The results obtained from this study showed that the diameter and hight mean a also the annual hight growth and the ALNUS SUBCORDATA volume mean are in order 40 cm, 23 m, 0.75 m, 45.58 silve and compared to ACER VELUTINUM and FRAXINUS EXCELSIOR are greater amounts. From the view point of tree distribution in different diameter levels it was distinguished that ACER VELUTINUM and FRAXINUS EXCELSIOR have normal distribution but ALNUS SUBCORDATA lacks this attributes. From the view point of studied qualitative attributes except the trunk twist attribute there is a significant difference at the level of a=1% among the three species. From this view point AFFORESTATION with ALNUS SUBCORDATA species regarding the QUALITATIVE AND QUANTITATIVE variables has the best condition and regarded to ACER VELUTINUM and FRAXINUS EXCELSIOR the have more developing capability.
