The present study aimed to assess, identify and quantify the fifteen main forest genus and species legally exploited in the state of Acre, Brazilian Amazon, as well as to analyze the number of authorizations issued to the exploitation of managed forests, the total wood volume, and total managed area licensed by the Environmental Institute of Acre (IMAC) from January 2005 to August 2012. Gathered data showed that the licensed area and volume had an increase during the analyzed period, reaching the highest numbers in 2010 and 2011, respectively. The fifteen main genus and species licensed were: Cumaru-ferro (Dipteryx spp.), Garapeira (Apuleia spp.), Sumaúma or Silk Floss tree (Ceiba spp.), Açacu or Sandbox tree (Hura crepitans L.), Matamatá (Eschweilera spp.), Jatoba (Hymenaea spp.), Tauari (Couratari spp.), Manitê (Brosimun spp.), Caucho (Castilla ulei Warb.), Cedro (Cedrela spp.), Guariúba (Clarisia racemosa Ruiz & Pav.), Faveira (Parkia spp.), Copaiba (Copaifera spp.), Guaribeiro (Phyllocarpus riedelii Tul.) and Abiurana or Pouteria trees (Pouteria spp.).
