Resumo(s)
Porto Santo is a deeply eroded
oceanic island. The human uses of the
territory led to a massive destruction of
its primitive vegetation cover and its
substitution by new types of vegetation
constituted by plants adapted to the
novel perturbation regimes introduced
by human settlers. A vegetation cover
once dominated by trees or shrubs that
evolved isolated from herbivory during
millions of years, was replaced since the
XV century by herbaceous anthropogenic
vegetation, dominated by neophytes,
adapted to perturbation events imposed
by mammal herbivores (goats and
rabbits) and by dry-farming agriculture
(mostly barley). Agriculture and grazing
together with low climatic precipitation
levels promoted subnitrophylous types
of herbaceous vegetation. So, today's
Porto Santo vegetation is largely
dominated by two, yet undescribed,
herbaceous subnitrophylous phytocoenosis:
Lino stricti-Stipetum capensis and
Vicio costei-Echietum plantagini.
