Mapping Floristic Patterns of Trees in Peruvian Amazonia Using Remote Sensing and Machine Learning

open access: yesRemote Sensing, 2020
Recognition of the spatial variation in tree species composition is a necessary precondition for wise management and conservation of forests. In the Peruvian Amazonia, this goal is not yet achieved mostly because adequate species inventory data has been ...

Ecology and Classification of Forests in Turkey

open access: yesProcedia - Social and Behavioral Sciences, 2014
AbstractTurkey possesses all types of parent materials or bedrocks like metamorphic, sedimentary and volcanic belonging to different geological era and periods. Some parent materials contain evaporitic sediments with salt, gypsum and high contents of alkaline materials which mostly prevent the growth of climax vegetation.
