معرفی کتاب «Forest Resources in Europe 1950–1990 (Research Report / European Forest Institute)» نوشتهٔ Kuusela, Kullervo، منتشرشده توسط نشر Cambridge University Press (Virtual Publishing) در سال 1994. این کتاب در فرمت pdf، زبان انگلیسی ارائه شده است.
This volume provides a detailed country-by-country account of the increase in forest resources in Europe. The author discusses the implications of this expansion for the future health and vitality of the forests, for forest policy management and silviculture, and for the economic viability and environmental sustainability of the resource. An increase in thinnings and regeneration cuttings is advocated, replacing unstable tree species by true climatic climax species, and shortening rotation ages. The author concludes that preserving the sustainability and biodiversity of Europe's forest ecosystems can be achieved by maintaining the genetic diversity, density, age and health stability of forests, protecting biotopes of endangered species and establishing cultural biotopes and strictly protected natural reserves.

This Expansion, In Standing Volume And To A Lesser Extent In Area, Is A Continuation Of A Trend That Began During The Nineteenth Century. After Presenting The Historical Developments, The Author Discusses The Implications, Should This Trend Be Allowed To Continue, For The Future Health And Vitality Of The Forests, For Forest Policy Management And Silviculture, And For The Economic Viability And Environmental Sustainability Of The Resource. An Increase In Thinnings And Regeneration Cuttings Is Advocated, Replacing Current Unstable Tree Species By True Climatic Climax Species, As Is A Shortening Of The Currently Over-long Rotation Ages. The Author Concludes That Preserving The Sustainability And Biodiversity Of Europe's Forest Ecosystems Can Be Achieved By Maintaining The Genetic Diversity, Density, Age And Health Stability Of Forests, Protecting Biotopes Of Endangered Species And Establishing Cultural Biotopes And Strictly Protected Natural Reserves.

This volume describes the implications for the long-term health of the forests should the current expansion be allowed to continue and suggests active measures to ensure the sustainability and biodiversity of this important resource. European forests and forestry are at a stage in which both the current situation and development trends need to be analysed and the policy implications formulated.
