¿CASTAÑAR PARA FRUTO O PARA MADERA? CONSIDERACIONES SOBRE SU AUTOECOLOGÍA
The autoecology of species has provided quantified information on the characteristics of the environment in which forest species grow. These studies have been carried out using research done on a regional basis, and the study of the sweet chestnut represents the first case that has arisen of the same species appearing in two such very different ways. The chestnut has been exploited by man since ancient times and continues to be of use to humans today as a source of edible chestnuts and/or timber production. This work examines the differences in autoecological characteristics between chestnut stands for the production of nuts and timber. The results indicate that chestnut orchards in Spain tend to be located at higher altitudes and on sites with a less pronounced slope than for trees used for timber production. Chestnut orchards are located under climates with greater winter precipitation, lower summer precipitation and greater excess precipitation, as well as lower average annual temperatures and potential evapotranspiration. From the soil point of view the orchards are found in soils which are significantly less sandy, more silty and clayey, and with a significantly lower permeability, as well as a greater water-holding capacity. Taking the whole set of ecological parameters analysed, it can be seen that it is not the soil or physiographic characteristics but rather the climatic characteristics which basically determine the use which the chestnut stands will be given. It therefore seems appropriate to continue using these climatic characteristics as a guide when assigning the most suitable use for a chestnut stand, whether for the production of nuts or timber.
