Resumen:
Secondary forests will likely dominate future tropical landscapes, and
the ecosystem services they provide to humanity will be particularly
relevant. However, few empirical studies provide quantitative evidence
of how the supply of ecosystem services change along secondary forest
succession. The need for such information is particularly pressing for
tropical dry forests because of their extensive global coverage and a
high degree of disturbance. Here we examine the changes in the potential
supply of ecosystem services and the interactions among them along
secondary tropical dry forest succession for a site on the Mexican
Pacific coast. Using data from a chronosequence of twelve sites followed
over ten years, we characterized changes in five ecosystem services
along a successional gradient from abandoned farmland to old-growth
forests: forage, multiple forest resources, microclimate regulation,
carbon storage and carbon sequestration. The long-term recovery
trajectory for each service was modelled using linear and non-linear
mixed models. Interactions among them were examined over different
timeframes using Spearman correlations. The results showed rapid
non-linear recovery of multiple forest resources provision, microclimate
regulation and carbon storage within the first two decades of
succession. Carbon sequestration increased slightly over time, while the
supply of forage showed no clear trend. The strength of the interactions
among pairs of services changed through successional time, being
particularly higher in farmlands and old-growth forests. Our findings
suggest that adaptive forest management practices that foster the
natural regeneration of tropical dry forests are cost-effective
mechanisms to recover the supply of critical ecosystem services for
local actors by meeting their livelihood needs as well as those for the
global community through climate change mitigation. Maintaining tropical
dry forest resilience will highly depend on the maintenance of diversity
in terms of species and ecosystem services.
