Effects of harvesting on the structure of a neotropical woody bamboo (otatea: guaduinae) populations
Natural populations of Otatea acuminata (Munro) C.E.Calderón & Soderstr. subsp. aztecorum (McClure & E.W. Smith)R. Guzmán, Anaya & Santana-Michel were studied in the Sierrade Manantlán, Jalisco-Colima, in Western Mexico. The objectiveswere to compare the structure of otate populations at...

| Sumario: | Natural populations of Otatea acuminata (Munro) C.E.Calderón & Soderstr. subsp. aztecorum (McClure & E.W. Smith)R. Guzmán, Anaya & Santana-Michel were studied in the Sierrade Manantlán, Jalisco-Colima, in Western Mexico. The objectiveswere to compare the structure of otate populations at differentharvesting levels, in order to evaluate the changes occurred dueto management and to obtain the best prediction factor for culmproduction. Forty-one 50m2 plots were randomly established inharvested and non-harvested stands, and were observed over a 2year period. There was no significant difference between harvestedand unharvested stands, but the latter had higher densitiesand longer stems on average. Culm diameter and heightwere significantly different according to soil type in a nonparametricANOVA. A backward lineal regression analysis identifieda prediction model for juvenile culms production. Present exploitationlevels by artesans appear to be sustainable. |
