Resumo(s)
Saltmarshes are one of the coastal ecosystems that
have endured higher anthropogenic pressures and consequent
transformations over the centuries. Its privileged position
in transition areas between land and sea (estuaries)
has placed these ecosystems at the run for urban-industrial
growth and agricultural development. Thus, Ria de Alvor saltmarshes were no exception regarding land use changes,
which were mainly driven through the works undertaken
by the Development Plans (1940-60). These incorporated
saltmarshes´ reclamation for agriculture by exsiccation and
the destruction of vegetation, and also building a small wall
to prevent salt water to enter (dykedland), leading to the
disappearance of about 60% of the Ria de Alvor saltmarshes
between 1958 and 2010. However, this process provided
the opportunity to new types of marshland to emerge, resulting
from the implementation failure of the agricultural
dykedland in the Ria de Alvor mouth. The controlled and
secondary saltmarshes developed as new typologies of this
ecosystem that deserve special attention with regard to habitat
management, since they can be differentiated from natural
marshes by their structure and floristic composition
