Year of compilation: 2002

Site description
The Portuguese side of the Guadiana estuary, at the country's south-east corner. There is an extensive area of saltpans and of claimed land (used for cattle and sheep-grazing) that was formerly saltmarsh.



Key biodiversity
Important numbers of breeding, wintering and migrating waterbirds use this site, as do some steppic species such as Tetrax tetrax, Burhinus oedicnemus, Glareola prantincola and Melanocorypha calandra. This is the only portuguese site where Calandrella rufescens breeds. Untill 1999 Falco naumanni bred at this site.



Pressure/threats to key biodiversity
There is a proposal of management plan for Natural Reserve but it was not disccussed in public. Like other litoral sites in the area, Castro Marim suffers high disturbance from tourism and urbanization. Two SPEA conservation projects were fisnished in 2002. One aboutwintering waders population in the saltmarshes, and other about secondary saltmarshes populations. These projects deffined management measures for bird conservation in the area.
