Beschreibung
The book presents the state-of-the-art of forest resources assessments and monitoring and provides links to practical applications of forest and natural resource assessment programs. It gives an overview of current forest inventory systems and discusses forest mensuration, sampling techniques, remote sensing applications, geographic and forest information systems, and multi-resource forest inventory. In addition to the assessment of the productive functions of forests, particular attention is given to the quantification of non-wood goods and services and the relationship of forests to other landscape elements. All methodology is presented in the framework of sustainable management of the multiple functions that forests provide to the natural environment and to society.
The book was developed as a reference text for (forest) biometricians, practitioners involved in forest and natural resources assessment and monitoring programs, and graduate students with a strong interest in becoming forest inventory specialists.
When we talk about forests, we talk about 30% of our planet’s land surface 6 area. In 2000 there was an estimated 3 870×10 ha of forest worldwide, of which 1 5% is in forest plantations and 95% in natural forests (FAO 2003). Forests are not only a source for timber; they also generate significant nonwood goods and services, mitigate climate change, conserve biological diversity, provide prot- tion from natural hazards, and not least: provide recreational areas for an increasingly urbanized world population. The availability of timber and n- wood goods and services is waning as deforestation and degradation of tro- cal forests continue. While forest area has stabilized or is slightly increasing in the boreal and temperate regions, the annual loss of forest area in the tropics and subtropics is decreasing. Between 1990 and 2000 the annual rate of defor- 6 estation was estimated to be 14. 6×10 ha (approximately 0. 38%) and took place mainly in tropical and subtropical forests (FAO 2003). The net annual rate of 6 change is about 9. 4×10 ha (0. 2%). Maintaining and enhancing forest areas and the vitality of forest ecosystems is a widely accepted political goal, which is often opposed by conflicting demands of various stakeholders.
