The potential distribution of forest tree species is modeled using machine learning CART (classification and regression tree analysis) and Random Forest (RF) algorithms. Maps corresponding to RFregression and RF classification algorithms are available for download with further description on this website. Presence / absence records of the most dominant European tree species are used to process a RF classification in order to predict the presence/ absence of each species and a RF regression to predict continuous values from absence to presence of that species.
When travelling to exotic places, choose your souvenirs carefully.
Trade in items such as woodcarvings, red coral or ornaments with fur or feathers, is often regulated and permits are required to bring them home. Check the rules, as there are strict laws governing exports of wildlife and you could risk having your souvenir confiscated.
