Trees for People

This book is about the importance of trees to people as sources of fuel, shelter, timber, and recreation. It will develop as short chapters covering varied aspects of forestry and natural woodlands.


1. Reclaiming the desolated northern lands

Forests and woodlands are the dominant natural vegetation in many regions of the world. The areas of forest and woodland are increasing in two of four main climatic domains of the world: boreal, and temperate. Chapter 1 introduces the book by describing how the vast forests of the north regrew after the ice-age, then were used by people for their survival, development and leisure.

2. Energy of sunlight harvested as wood

 Fagus sylvatica leaves SMALL

Leaves of beech, a tree of great value as timber and aesthetically. 

Life on Earth is powered by sunlight and trees predominate in capturing this energy. Trees use this energy to incorporate carbon from the atmosphere to synthesize organic matter, mainly as wood. This chapter describes the pathways of energy and matter from green leaves through to harvested timber.

 3. Leaves: when should they fall?

How do some deciduous broad-leaf tree species manage to flourish in regions that seem suitable only for coniferous needle-leaf species? Why do some needle-leaf conifers shed all their leaves before the onset of every winter? Answers to these questions may be found in recent studies showing how all types of leaves are adapted so that their gain of energy and materials is optimal under a range of severe physical and biological constraints.
