Resumen:
Commercial harvests can threaten tree species harvested for their bark.
Amphipterygium adstringens is a dioecious tree, endemic to the tropical
dry forests of Mexico, where it is intensively harvested for its
medicinal bark. Limited information hinders developing sustainable
management strategies for A. adstringens. We assessed bark regeneration
for male and female trees, and evaluated the effect of tree sex and
diameter, debarking treatments and cutting seasons on bark regeneration
and tree survival rates. Bark regeneration was higher for wet season
harvested trees (vs. dry), regardless of their sex. Bark regeneration
was higher on female than on male trees. There were significant
interactions of harvest season, harvest treatment and tree sex diameter
on bark regeneration and survival. Overall, the highest bark
regeneration rates occurred in female trees with >= 20.1 cm diameter
that were wet season harvested with a 50% debarking intensity.
Consequently, wet season and intermediate intensity harvests appear to
foster sound management, but we recommend against targeting exclusively
a single demographic group (i.e., large female trees) due to potential
negative impacts on species demography and bark supply. A grounded
strategy for sustaining bark harvest would also need to take into
account relevant aspects of local socio-ecological context, including
harvest interactions with other land uses.
