Autoecology of sweet-chestnut stands in Andalucia (Spain)

open access: yesForest Systems, 2002
This paper is a characterization of the chestnut stand biotopes in Andalucia (Spain). The distribution of these stands is quite iregular, with four areas of chestnut tree dominant presence, located in Granada, Huelva, Malaga y Sevilla respectively, totalling over 9.000 ha. In these locations, 23 forest sites have been evaluated by computing a set of 34
