Padule Orti-Bottagone, Regional nature reserve in Piombino, Italy.

Padule Orti-Bottagone is a 126-hectare regional reserve in Piombino's eastern coastal strip, near Torre del Sale. It holds a brackish marsh of ponds and wet meadows beside a freshwater marsh, the last remnant of the wetland that covered the Cornia river plain until a century ago. Salicornia and halimione grow in the salt marsh; reeds, sedges and marsh orchids in the fresh water.

The reserve was created by the province of Livorno in 1998, covering about 126 hectares on the eastern coastal strip of Piombino near Torre del Sale. A WWF Italy oasis has operated within the area since 1991. The marsh is a remnant of the brackish wetlands that dominated the Cornia river plain until a century ago, and it has been proposed for inclusion among Ramsar wetlands of international importance.

The reserve operates under WWF management and offers guided tours for schools and researchers interested in wetland ecosystems. Visitors can see how local conservation efforts support education about the importance of protecting these natural habitats.

Access to the trails is seasonal, with visits available on weekends from October to May and on weekdays from June to August. Observation towers are positioned throughout the area for watching birds during these visiting periods.

The reserve hosts around 231 bird species and serves as a crucial stopover for migratory birds traveling Mediterranean routes. Pink flamingos are among the notable visitors that regularly gather in the saltwater sections.
