The otter, caretta caretta turtle, four-lined snake and unique fish species are found in the area, among many other endangered species. Although it is designated as an important bird area, dangers such as hunting, tree-felling and insensitive tourism (e.g. disrupting the sand dunes) have threatened the area. Sadly, fertilizer and pesticide use is also threatening the lagoon. Agriculture, over-grazing and other challenges instigated by man continue to affect the area. Other important natural areas and ecosystems are the Papa lagoon and Prokopos or Prokopou lagoon, as well as the Lamias swamp lake.
The Kotychi lagoon and Strofylia wetlands together represent the largest remaining wetland system in the Peloponnese. The area was recognized as a Wetland of International Importance in 1975, now protected by the RAMSAR convention. It also falls under the Natura 2000 designation. The wider area is almost 136,000 kilometres square, belonging to both the Achaia and Ilia Prefectures or regions.
The wetlands are on 15,000 kilometres square, with Kotychi covering 7,000 of these by itself. It is an ideal biotope for birds for wintering and breeding, offering reed beds for protection and much food in terms of fish and amphibians.
