VELASCO BAUTISTA, Efraín et al. Predictive models of wild edible mushroom production in conifer forest of Tlaxcala state, Mexico. Rev. mex. de cienc. forestales [online]. 2010, vol.1, n.1, pp.95-104. ISSN 2007-1132.

Wild edible mushroom production under natural conditions is determined by the biology of each species, the tree dimensions of the stands where they grow as well as by soil and climatic elements of their habitat. If the ecology and tree-dimensions of the fungus-collecting sites is known, it's possible to link their productivity to the phyisiographic elements of forests. Thus, a monitoring study of wild edible mushrooms was carried out during three rainy seasons (2004-2006) at Tlaxcala state, in three locations that belong to Tlaxco, Terrenate and Nanacamilpa. In each location, ten 33 x 33 m (1,089 m²) permanent-sampling plots were placed, where environmental data were taken as well as the number and fresh weight of carpophores and tree-mensuration. Regression models were obtained in order to find association among those variables. 153 wild edible mushrooms were found, with a total production of 193.688 kg. Results show that the total wild-edible mushroom production can be predicted as it is related to the number of trees and tree-mensuration characteristics (BHD, total height and cover) of each location, as well as to climatic factors such as temperature and average year rainfall during the time of sampling.
