Not recover deforested forest diversity, says MPEG

The observation that 20% of deforested areas in the Amazon forests are regenerating places Brazil in the center of an international discussion on the ecological value of secondary forests. Long-term studies conducted in northeastern Pará by scientists of the Museum Paraense Emílio Goeldi (MPEG) show that even after 40 years at rest, the secondary forests of the region only recovered 35% of tree species over 10 cm in diameter that had originally.
According to calculations of the researcher Cláudio Almeida, the National Institute for Space Research (Inpe), about 132 thousand of 680 thousand square kilometers of forests in the Amazon were dropped in the process of regeneration by 2006. And, according to experts, these forests may even grow into mature forests, but hardly recover the diversity of species that had originally. An area of secondary forests (or barns) equivalent to all that was deforested in the Amazon in the last seven years (2002 to 2008), sufficient to cover the forest states of Pernambuco and Alagoas.
At first glance it may seem that seven years of deforestation have been "undone." But the simplicity of the figures hide a web of highly complex ecological factors. Besides regeneration, the time for regeneration is insufficient. According to Almeida, the average life expectancy of a secondary forest in the Brazilian Amazon is only five years before being cut and burned again. (Source: O Estado de S. Paulo)
