Palau (de Dalt) Pond Nature · Palau-saverdera, Alt Empordà, Girona Image of Palau-saverdera, not of the place itself. The Estany de Palau de Dalt is a wetland lying between the municipalities of Pau and Palau-saverdera, within the Integral Nature Reserve of the Estanys, in the Aiguamolls de l'Empordà natural park, between the Estany de Vilaüt and the Estany de Palau de Baix, with which it forms a single unit. It covers 27.65 hectares of former ponds drained in the 18th century and now converted into closes, a traditional agro-pastoral system of meadows enclosed by deciduous trees and drainage channels that allow the land to be flooded and washed of salts. Its vegetation of reed beds, glasswort marshes and tamarisk groves harbours habitats of Community interest and makes the area a key zone for breeding, wintering and migratory stopover for waterbirds.
