Three main types of natural habitat can be seen in the reserve. These different habitats are to be found side-by-side; sometimes gradually merging together. The presence of water is a constant – it covers more than 75% of the reserve’s surface area.
These areas tend to be largely composed of open water. These shallow and very brackish aquatic habitats are characterized by a scattering of low-growing vegetation which has adapted to this environment (‘salicornia’ or salt-tolerant plants), presenting visitors with a very open, somewhat bleak landscape. Here, as in the saltmarshes, there is no escape from the sun and the heat of the summer-time.
