ANDREIS, Cáren et al. Phenology study in three successional stages of a seasonal deciduous forest in Santa Tereza, RS, Brazil. Rev. Árvore [online]. 2005, vol.29, n.1, pp.55-63. ISSN 1806-9088.  http://dx.doi.org/10.1590/S0100-67622005000100007.

The present study was accomplished in forty permanent plots belonging to three forest successional stages, denominated: Brush Forest, Secondary Forest and Mature Forest, in a seasonal deciduous forest in the municipal district of Santa Tereza, RS, Brazil. Phenologic observations were accomplished fortnightly for 53 arboreal species, in an average of 8,4 individuals per species, during the period of November 2001 to November 2002. The stages observed were flowering, fruiting and foliage change. The results indicate that the reproductive activity remained relatively low for three successional stages during the observed period, with a tendency to be even lower during winter. The total amount of leaves on the trees, regardless of the successional stage, decreased from approximately 85%, in the period of higher vegetative activity, to 35% in the winter, resting season. The Mature Forest maintained the largest percentage of leaves during the studied period.
