RANDOM FORESTS FOR CLASSIFICATION IN ECOLOGY

Ecology, 2007
Classification procedures are some of the most widely used statistical methods in ecology. Random forests (RF) is a new and powerful statistical classifier that is well established in other disciplines but is relatively unknown in ecology. Advantages of RF compared to other statistical classifiers include (1) very high classification accuracy; (2) a ...

Combining Camera Relascope-Measured Field Plots and Multi-Seasonal Landsat 8 Imagery for Enhancing the Forest Inventory of Boreal Forests in Central Russia

Remote Sensing, 2018
The study considers a forest inventory for the mean volume, basal area, and coniferous/deciduous mapping of a large territory in central Siberia (Russia), employing a camera relascope at arbitrary sized sample plots and medium resolution satellite ...

Agroforestry as Policy Option for Forest-Zone Oil Palm Production in Indonesia

Land, 2020
With 15–20% of Indonesian oil palms located, without a legal basis and permits, within the forest zone (‘Kawasan hutan’), international concerns regarding deforestation affect the totality of Indonesian palm oil export.

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

Remote 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 ...

Sheep in the Vineyard: Suitability of Different Breeds and Potential Breeding Objectives

Animals, 2022
Protecting a breed of sheep is simple when there is demand for its breed traits, but new market options are often hard to find. In general, grazing sheep are able to take over some viticultural work.

Czech forest ecosystem classification

Journal of Forest Science, 2003
Forest classification, made up by Plíva and Průša (Plíva 1971), has been used in the Czech Republic forestry since 1970. This classification is based on ecological factors of the environment.

Are natural disturbances represented in strictly protected areas in Germany?

Global Ecology and Conservation, 2021
Natural disturbances are largely suppressed in Central European landscapes due to economic and human safety concerns. European goals to increase the extent of secondary wilderness areas have the potential to support the restoration of threatened habitats
