Contribution to the Study of the Structure of the Main Ligneous Species in the Preservation of Forest Spaces in the Monts of Saida and Dhaya (Algerian West)
Journal Title: Ecologia Balkanica - Year 2014, Vol 6, Issue 1
Abstract
In arid Mediterranean region, the structure of forest stands is the image of their capabilities durability and resistance demonstrated by the rate of land by persistent vegetation recovery rate by stratum and living space, which are useful for understanding the dynamics of vegetation. These three criteria used to classify the different layers according to their importance in bioclimatic zones, the semi-arid and sub-humid, and the most dominant in Algeria. The arborescent and shrub Stratum plays an important role in the two bioclimatic zones points of view recovery; points of view land soil occupation in semi-arid is the under shrub stratum in which premium and shrub Stratum for the sub-humid. Eight principal forest species that dominate the area, their living space depends on density and regeneration capacity, it varies between 28 and 222 square meter depending on the species inducing bad conduct densities and silvicultural work. For that, to preserve these strata with the species composition and ensure stability, a silvicultural work or plantations are necessary.
