To deal with the large number of explanatory variables and to find redundant variables, model diagnostics and step-wise variable selection were evaluated. Classifications were ten-fold cross-validated for 517 trees that had been visited in field surveys and detected in the ADS40 images. The ...
Reviews of forest preference studies [22,23,24] demonstrate that people tend to prefer forest scenes that exhibit a high number of large trees of different ages and species with an understory composed of low, sparse ground vegetation. Dead trees, or slash, commonly elicit more negative preference...

Hawthorn trees can become infested with pests, includingaphidsand scale, which are small insects that survive by consuming plant sap from leaves. Caterpillars, leaf miners and borers are also pests of hawthorn trees. Goodshoot/Goodshoot/Getty Images ...
The spatial patterns of trees and their interactions provide critical information on community structure, species coexistence and significantly determine reproduction, growth, mortality, dispersal, resource use, gap creation, and understory development1,2. Especially for the natural forest, the complex spati...
Over millennia, human intervention has transformed European habitats mainly through extensive livestock grazing. “Dehesas/Montados” are an Iberian savannah-like ecosystem dominated by oak-trees, bushes and grass species that are subject to agricultural
The fuel classification system in the NFDRS is mainly based on trees, shrubs, grass, and rainfall. The fuel classification system in the CFFDRS is mainly based on the dominant population and forest age. Kriging is a geostatistical interpolation method based on the spatial covariance of the data...
