It may come as a paradox that while interest in tropical forests worldwide has been steadily growing in the last century, this has in no way halted the continued loss and degradation of one of earth's grandest terrestrial ecosystems. In fact, the extent and rate of degradation is accelerating. Some places have completely lost their original forests, while in others the structure and biomass of the forest have been irreparably damaged. Concern for this loss is not limited to the extinction of animal and plant species.

Globally, according to FRA 2000, planted forests accounted for only 5% of forest area, but up to 35% of industrial roundwood supply. This is anticipated to rise to 40-44% by 2020. Planted forests reflect a higher social, environmental and economic importance than their area would suggest. Many countries have existing planted forest data that is not based upon forest inventory, is incomplete and often outdated. Thus it is difficult to measure and plan the quantity and quality of planted forest resources and the provision of goods and services that they supply.

It is widely believed that tropical soils (mainly Oxisols) have excellent physical characteristics such as high infiltration rates, high permeability of water, good and stable soil structure and that consequently, they can support mechanized agriculture. However in the Eastern Plains (Llanos Orientales) of Colombia, when Oxisols are subjected to tillage using disc harrow, soil physical conditions deteriorate rapidly.

This report presents the results of an extra budgetary project which analyses similarities and common approaches in European national forest legislation. The forest laws of 23 countries have been examined in order to find out whether provisions are made to put into practice the following three legal issues: (1) reforestation obligations after logging through final cutting or loss of forest cover due to fire and natural calamities, (2) regulations concerning public access to forests and (3) public use of non-wood forest products occurring on forest land.
