Pines of Silvicultural Importance


Book Description

Pines are the most economically important group of trees in the world, covering large parts of the Northern Hemisphere and also being of silvicultural significance in many countries in the Southern Hemisphere. This book is compiled from 65 datasheets on pine from the Forestry Compendium Global Module (published by CABI on CD-ROM). For each species, there is information on common names, taxonomy, botanical features, natural distribution, latitude range, climate, soil properties, silvicultural characteristics, pests, wood and non-wood products.
