(A) Repartition of loggers' monthly income between age classes. Elementary statistical analysis also showed that average monthly income of the third class was not significantly different from the one of the first class (t = 0.48; df = 51; p = 0.62), the second class (t = -1.02; df = 66; p = 0.30), the fourth class (t = -1.44; df = 45; p = 0.15) and the fifth class (t = -1.44; df = 45; p = 0.15). (B) Relation between revenues and wood diameter sold at all markets visited.
