Natural habitats
At Lera, the characteristic habitats of plant and animal species are limited to differently saline salt-fields, salt-pan channels and levees.
Even more diverse habitats can be found in the Fontanigge area with its reeds, halophyte meadows, dry, bare or gradually overgrown basins, islets in salt-pan basins, mudflats, and different habitat types on the banks. The remains of salt-pan houses, too, are highly inviting for some animal and plant species. The Fontanigge is enclosed by shrubbery as well as dry and wet karst meadows, while the high-sea embankments in the west are being washed by the shallow sea.
