Abstract: The bases of stems have accentuated conicity while the middle is more cylindrical. Larger trees tend to have stems that are more conic. Yield varies between logs and species as a function of the conicity of the commercial stem. The use of cutting templates can increase lumber yield, attaining an average of 59%.

“…Since the virtual credits are the functional currency of the DOF system, the monitoring agency will therefore consider that the remaining 1166.5 m³ of this unfulfilled conversion would still be available as unprocessed logs in the company's log deck. Given the variable mean volumetric yield among the sampled species, and among tropical Amazonian timber species in general (Mendoza et al 2019;Santos et al 2019;Lima et al 2020) it becomes clear that attributing a fixed value to CRV based on a general average does not match the reality of yield variations across the various aspects involved in industrial comercial timber production (multiple species, products and processing lines, among others). This makes the control process ineffective and may favor the illegal log trade.…”
