Resumo: | In the state of Amapá, Brazil, Calycophyllum spruceanum, a timber species native to the tidal floodplains of the region, has become an increasingly important source of construction wood for nearby urban markets. C. spruceanum exhibits prolific regeneration in agricultural fallows, and some rural inhabitants manage such sites for its production. Using simple linaer regression, we develop log and sawn lumber volume relationships for this species. Standard timber volume estimations using DBH and commercial height results in an adequate predictive model for measured commercial stem volume (R>0.09). Similarly, at the small sawmill we investigate, individual log volume was a good predictor of sawn lumber volume (R=0.90), with nearly half of the log volume converted to merchantable timber. The distribution of merchantable volume among standard board types varied between sawmills. We suggest that regional forestry practices would benefit from an applied research program aimed at quantifying the potencial for increased production ande more efficient processing of this and other native timbers. |

In the state of Amapá, Brazil, Calycophyllum spruceanum, a timber species native to the tidal floodplains of the region, has become an increasingly important source of construction wood for nearby urban markets. C. spruceanum exhibits prolific regeneration in agricultural fallows, and some rural inhabitants manage such sites for its production. Using simple linaer regression, we develop log and sawn lumber volume relationships for this species. Standard timber volume estimations using DBH and commercial height results in an adequate predictive model for measured commercial stem volume (R>0.09). Similarly, at the small sawmill we investigate, individual log volume was a good predictor of sawn lumber volume (R=0.90), with nearly half of the log volume converted to merchantable timber. The distribution of merchantable volume among standard board types varied between sawmills. We suggest that regional forestry practices would benefit from an applied research program aimed at quantifying the potencial for increased production ande more efficient processing of this and other native timbers. |
