Perceptions, object and observer of forest landscape and planning
Essay - 7 pages - Ecology & environment
For many centuries people have been concerned with perceptions of the natural world. Philosophers have written about it, psychologists have studied it, and, more recently, foresters have become concerned with it. However, when we speak of ‘perceptions of forest landscapes' in relationship to...

Landscape ecology, use and application in forestry
Essay - 6 pages - Ecology & environment
Many ecological processes result in or are affected by spatial patterns. However, the relative importance of different processes is very sensitive to the scale of analysis. For example, at a very local scale, species diversity is often strongly affected by competition and trophic interactions...
Visual analysis of forest landscape
