Chestnut (Castanea sativa), GLM

castanea_sativa2.jpgThe map shows distribution of the chestnut (Castanea sativa) – one of the rare and relic forest species in the Caucasus region. It is noticeable that all boubdaries of the species’ areal are determined predominantly by climatic factors such as dryness and low temperatures in winter (Sokolov et al. 1977). castanea_sativa1.jpgTherefore it can be assumed that the boundaries will change accordingly with the climate changes in Caucasius region. Because of the intensive anthropogenic pressure (agriculture and cutting) chesnut has been included in the regional castanea_sativafull.jpgRed Data books. (e.g. http://azecology.org/fce).
