By Kullervo Kuusela

This quantity presents an in depth account of the rise in woodland assets in Europe during the last 40 years. the writer discusses the results of this growth for the long run well-being and power of the forests and for the industrial viability and environmental sustainability of the source. He advocates a rise in thinnings and regeneration cuttings, exchanging at the moment volatile tree species with actual climatic climax species, and shortening rotation a while. the writer concludes that retaining the sustainability and biodiversity of Europe's woodland ecosystems will be accomplished via protecting the genetic variety, density, age and well-being balance of forests, preserving biotopes of endangered species, and setting up cultural biotopes and strictly secure traditional reserves.

Increment has increased more than growing stock, partly because of earlier under-estimations of the former. In many countries there are fast growing coniferous and broadleaved forests which increase the total increment. Measurement of increment in some countries supports the conclusion that the fertilising effect of deposited emissions has increased rather than decreased the increment. Exceptions to this general picture are planted forests in Mediterranean West where the increment seems to have been smaller than that expected earlier.

The coniferous percentage in Europe as a whole has been relatively stable except in those countries where there are substantial areas of coniferous plantations. 12. Increment has increased more than growing stock, partly because of earlier under-estimations of the former. In many countries there are fast growing coniferous and broadleaved forests which increase the total increment. Measurement of increment in some countries supports the conclusion that the fertilising effect of deposited emissions has increased rather than decreased the increment.

In countries where the proportion of the agricultural population is greater than average and where pasturing on forest lands is common. Recorded removals between 1950 and 1990 increased by 25% for the whole of Europe. An exception to this is the Mediterranean Middle region, where removals declined from the high levels that prevailed after the Second World War. Removals also decreased in Pannonic Europe since 1970, probably because of the unstable political and economic situation. The increase was proportionally largest in Atlantic Europe, as well as in Mediterranean West and East.
