Unasylva - Started in 1947, this quarterly publication is intended to cover a range of interests as wide as that of the Division whose work it mirrors.

Signed articles express the opinions of the authors and do not necessarily represent the views of the Organization.

Cover.

Cover: The Matterhorn, Switzerland, centre of a great tourist area. There will be a heightening interest in forestry as soon as two present-day trends are more widely appreciated. The first is the growing need for recreation for urban populations and the second the question of land for new forests. As cities get larger, people and particularly young people long more and more for open spaces. At the same time there is increasing depopulation of remote areas as in the Alps, leaving room for extension of forests. A problem is to reconcile the two interests.
