| Abstract | In order to test whether invasive exotic species, predominantly used for
restoring post-mining areas in north-eastern Vietnam, may be replaced by
ecologically superior native pioneer species, we conducted a drought stress
experiment in a greenhouse. We hypothesized that juvenile individuals of four
native pioneer tree and two native pioneer grass species have a drought
resistance comparable to two exotic reference species. Our results confirm
this hypothesis: even under drought, native trees had a higher biomass and
root : shoot ratio than exotic trees, although their maximum relative elongation
rate and biomass were reduced more strongly than for exotic trees with
respect to well-watered conditions. Native grasses had a higher root length
density and a similar drought-induced reduction of stomatal conductance
compared to exotic trees. In spite of a higher biomass reduction, native
grasses produced more biomass under drought in absolute terms.
Notwithstanding that further investigations of other adverse environmental
factors need to be performed, our results indicate with respect to drought
resistance that native pioneer species are a potential alternative to exotic
species for the ecological restoration of subtropical post-mining areas,
which may accelerate secondary succession. |
