Species diversity, forest structure and species composition in Tanzanian tropical forests

Forest Ecology and Management, 2003
Abstract The effects of tropical forest structure and species composition on species diversity were studied using the data of 279 biodiversity inventory plots, in the forest reserves of the East Usambara Mountains (EUM) in the northeastern part of Tanzania, among the 25 global “hot spots” for biodiversity conservation. A standard method of vegetation

A database for automatic classification of forest species

Machine Vision and Applications, 2012
Forest species can be taxonomically divided into groups, genera, and families. This is very important for an automatic forest species classification system, in order to avoid possible confusion between species belonging to two different groups, genera, or families.

Spectral variability of atlantic forest species

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
This paper investigates the spectral variability of Brazilian Atlantic Forest trees. Spectroscopy data (reflectance and transmittance) of full sunlight leaves were collected. The root mean square difference between pairs of spectra were used to estimate within- and between-species variability.

Assessing viability of forest species

Trends in Ecology & Evolution, 2001
Although forestry and forest management are often viewed as anathema to conservation, foresters world-wide are increasingly paying attention to the fauna within their managed lands. In the USA, the National Forest Management Act requires that every national forest should explicitly provide for the viability of vertebrate species on its lands.

Species Composition of the Forest

2003
One of the most striking features of tropical forests is their extraordinary species diversity (MacArthur 1969; Gentry 1982). The diversity of tropical trees supports a remarkable diversity of vertebrate and insect herbivores that have been shown to inflict a more intense pest pressure than in temperate settings (Landsberg and Ohmart 1989; Coley and ...

Forest Management Planning in Mixed-Species Forests

2017
In this chapter, we outline how forest management planning (FMP) develops in order to meet the requirements or even support the transition from far-from-nature monocultures to close-to-nature polycultures. We first introduce the various concepts and main steps of FMP in practice.
