Despite efforts to reduce deforestation in the Brazilian Amazon, there has been an up-turn in clearing rates since 2012. These increases are in part due to failures in deforestation control. Soybean planters, cattle ranchers, and timber merchants find ways to circumvent agreements and legislation. Here we explain some of the key problems with the implementation of the principal agreements and Brazilian laws that should be keeping clearing rates under control. To combat increased clearing in the Amazon, we suggest an urgent need to strengthen Brazilian environmental agencies, improve technologies used to monitor the effectiveness of clearing-reduction programmes, better integrate agrarian and environmental policies and integrate environmental enforcement across federal, state and municipal governments, as well as improve transparency along global supply chains and raise awareness among consumers to put market pressure on producers to avoid new deforestation. © 2019 Associação Brasileira de Ciência Ecológica e Conservação

An Amazonian savanna in northern Brazil known as the Cerrado of Amapá is under imminent threat from poor land-use planning, the expansion of large-scale agriculture and other anthropogenic pressures. These savannas house a rich and unique flora and fauna, including endemic plants and animals. However, the area remains under-sampled for most taxa, and better sampling may uncover new species. We estimate that only ∼9.16% of these habitats have any kind of protection, and legislative changes threaten to further weaken or remove this protection. Here we present the status of knowledge concerning the biodiversity of the Cerrado of Amapá, its conservation status, and the main threats to the conservation of this Amazonian savanna. To secure the future of these unique and imperilled habitats, we suggest urgent expansion of protected areas, as well as measures that would promote less-damaging land uses to support the local population.
