This book, which contains 7 chapters, is about the state of the world's forests in 2020. It draws on the results of FAO's Global Forest Resources Assessment 2020 (FRA 2020). FRA 2020 examined the status and trends of more than 60 variables related to the extent, characteristics, condition,...

This study was conducted on the floor coverings deployed in the forest irrigation stands for pine trees Pinus brutia Ten. In province of Nineveh, which are located in northern Iraq. The purpose was to know edge and determine the differentiation of main stem shape of pine trees, form study the stem...

This study was carried out in Zakho area on stand Populus nigra. Different types of measurements had been taken for the area, measurement cover number of trees of hectare for each stand. Sixty Random samples which area of (0.01) ha. By using different regression in statgraph system to derive...

Spatial patterns of species at different life stages are an important aspect for understanding causal mechanisms that facilitate species co-existence. Using Ripley's univariate L(r) and bivariate L12 functions, we analyzed the spatial patterns of two canopy species at different life stages in mixed ...

This paper presents the results of a study conducted to maximize the use of Egypt's closed water system through finding the most economically feasible tree species to expand in cultivation for the purpose of producing oils, dyes, entering paper industries, and establishment of sustainable wood...

This study has been conducted of irrigated Populus nigra plantation in Warso village - Zakho - Governorate of Dohuk at the Northern part of Iraq. The aims were to determine the dry weights biomass for different tree and stand parameters above ground surface; in order to gain a clear view on carbon...

This research has been conducted to study the effect of Conocarpus trees and their roots on some of soil physical properties. The soil physical properties are moisture content, bulk density, total porosity, mean weight diameter (dry sieveing) and soil penetration resistance. Some soil samples are...

This CD-ROM contains the key findings and the main report of the Global Forest Resources Assessment 2005 (FRA 2005). Six themes representing important elements of sustainable forest management are discussed. These themes include: extent of forest resources; biological diversity; forest health and...

This research aimed at studying plant biodiversity in a burnt and afforested region AL MEED AN from Lattakia's forests. This is done in order to know the effect of afforestation on plant biodiversity. We have compared the biodiversity in three types of forest lands: burnt and naturally regenerated, ...

This paper provides a precise description of the studied samples that were defined in the Mahmoudiah forest in Syria. The results represent the analysis of logical scientific conclusions, calculations, ecological, topographical, climate analysis, as well as the study of the fertility and...
