**2.2.1 Sustainable forest management**

Exploration of candeia populations, in the form of sustainable forest management, is only authorized by the State's environmental agency for fragments with occurrence of at least 70% of individuals of the species *Eremanthus erythropappus* or *Eremanthus incanus*. This restriction is derived from the need for restoration of the area through natural regeneration, where areas with greater dominance of the species are more likely to recover and return to the initial stage. Beyond this point, the guarantee of the sustainability of these populations is correlated with the quality of the harvest project and compliance with the State's environmental laws.

Barreira (2005) studying the genetic diversity of candeia populations (*Eremanthus erythropappus*), in which she sought to quantify and compare the intra-population genetic variation and reproductive systems of candeia before and after exploration, noted that the species is suitable for management without loss in genetic diversity, as long as 100 individuals/ha are preserved as remnants. The study also showed a strong spatial genetic structure in the population, where trees in a 200 meters radius presenting some degree of kinship, with a 95% probability.

In addition to these efforts, the owner of the area under management must present a map of his farm containing the areas to be managed as well as the areas of Legal Reserve (20% of the total farmable land) and Permanent Preservation Areas (areas adjacent to waterways, with declivity greater than 45 º, hill tops and areas 1800 meters above sea level).
