Abstract

The study was conducted in northern Iraq, 70 km to the north of Mosul city of Atroosh natural Pine forests (Pinusbrutia Ten.) between 36˚ 31 ̄ - 36˚ 51 ̄latitude and between 43˚ 20 ̄ - 43˚ 21 ̄ longitudes. The area elevation is between 782m and 1036m also with average slope between 3.65% – 18.91% . These are renewable Natural forests which should be maintained and managed with great efficiency.Number of seedling variables were measured during this study using to samples. Measured variables include, basal area, height, diameter.Other variables like the Natural Regeneration variables were obtained from models and mathematical formulas.These information were recorded in special forms then analyzed using softwares like (Arc Info version 9.3, Gs+ version 9 and Geo Coordinateconversion.We used Statistics and Geostatistics in addition to Remote Sensing and GIS to measure the natural and spatial distributions of forest trees in the Atroosh district, these are natural forests dominated by Pine trees in addition to Oak, Crataegusazaralus , Rhuscoriari and others. The purpose of this study is the search for information about the forests like Diversity, Natural Regeneration, Distribution of plant Communities for the pine forests in the Atroosh District. Such informative areessential for sustainable productive for the Natural forests Resources by correlating among the Stand variables using mathematical models and Computer Softwares. The results show that Seedling had the greatest significant variation with respect to regeneration. There was inverse relative with crown cover and a high correlation actress with respect to the interference between diameter and height. There was an increase in the basal area with the increase in density and average height. sixteen seedling sampling out of twenty showed Significant correlation between diameter and height with coefficient of determination (R²) between 0.7- 0.99 ; six of these samples were located between east toward north and northeast; this confirm the role of aspects in growth and regeneration
