abstract = {Insufficiency of necessary information to the status of utilization of forests and agroforests trees for biochar production in the municipality of Leon triggered to some level of uncertainties on how to approach and deal with the issue. Thus, this assessment survey has been conducted to find out the proximities of such economic activity within the perimeter of alienable and disposable land of the municipality. The survey was done by transect mapping of the biophysical condition, by observation and by documentation of some economic activities of the local people including the siltation of Sibalom-Leon river beds. Results indicate that there is really an economic activity related to biochar production from harvesting of top stems and branches of different premium and indigenous species of forests and agroforests trees including leguminous trees. Local people harvested those trees in allowable and sustainable manner. There are no total pullout of the trees but instead it is just top cutting and branch pruning, thereby allowing the trees to regenerate in 4 to 5 months. It was found out that there was at least 1 biochar production per1.5 kilometer square from the 250-600 meters above sea level and at least 1 biochar production per 2.5 kilometers square below 250 meters above sea level at an average of 1 ton per production cycle with at least 30-35% recovery rate. The present practice of the local community is sustainable, risk of vulnerability to rapid degradation of forests and agroforests resources stay at the lower level, but in order to sustain its ecological services, re-enforce planting of trees especially leguminous species is highly recommended to compensate the loss of fertility during the regeneration of pruned trees.},
