【 摘 要 】

The Brazilian Cerrado is the most bio-diverse and threatened savannah on the planet. This biome has already lost 48.2 percent of its original floral cover and is being affected by an intense process of habitat fragmentation. The purpose of this article is to verify if and how governmental and non-governmental conservation measures are protecting the remaining native Cerrado vegetation and whether these measures are encouraging connectivity. Results show that the effects of conservation units are limited, since only 3.1 percent of the biome is within fully protected areas. It was also found that public agencies are much more involved in conservation planning than actions in the field. Conservation projects are often implemented in the same territories, leading to the squandering of resources and ineffective results. Another problem is that many projects are dependent on international organizations and resources. Conservation initiatives in areas under private ownership are rare and economic or fiscal incentives that support such initiatives are sporadic and inadequate. The article concludes by suggesting that the Cerrado should become the focus of specific conservation policies, integrating governments, civil society and economic sectors and actors, especially farmers.
