• Uneven-aged Forest
• Forest Regulation
• Selective Harvest

The cutting intensity (CI) and the cutting cycle (CC) in tropical forests in the Amazon are critical parameters for the regulation of sustainable wood production. This study aimed to evaluate the use of the Mexican Method of Forest Planning (MMFP) in the Eastern Amazon. The study was conducted in the municipality of Moju, Para State (02 degrees 08'14''S and 48 degrees 47'34"W), in an area subjected to reduced impact logging (RIL), with IC 21 m(3) ha(-1) Manilkara huberi (Ducke) A. Chev. were 22 and 19 years, respectively, for the highest growth rate (i3), which falls within the recommended for tropical forests. The calculated IC (31,888 m(3) ha(-1)) for a CC of 35 years was also close to the recommended for tropical forests in the Amazon (20 to 40 m(3) ha(-1)). The estimates for the years 1998 and 2010 did not differ from the observed in the plots (p > 0.05). The MMFP can be used to indicate the cutting intensity (CI) and the cutting cycle (CC) in forest in the Eastern Amazon.
