Forests fires can be either wild, prescribed or intentional and they are one of the most
important threats to natural forests ecosystems in Mexico. In the years 2009 and 201 0
approximately 70 ha of forests were bumt at the Barranca del Cupatitzio National Park in the
municipality of Uruapan in the state of Michoacan. A study to follow development of maaufungi
communities in burnt plots at this national park including changes in richness and composition of
the macrofungal species associated was carried out Three plots of 300 m2 each were studied
throughout three years (i.e. one year before and two years after the forests fires took place); 81
taxa of fungi were registered of which 10 are considered as pyrophilous. Results showed little
differences in species richness composition in each plot before the fire; however a year before
the fire and two years after the fire, great differences in species composition ocamed (i.e. high
temporal beta diversity). Results concluded that the macrofungal species composition is a good
indicator of the intensity and effect of the fire on forests communities.
