Wetlands are areas that are permanent or periodically covered by water or immersed in water. Different
types of wetlands have been created by hydrological and topographical conditions. Lorestan province
with an area of 28323 sq. Km, due to the existence of rivers, streams, springs, small and large,
permanent and non- permanent, has provided a ground for the formation of wetland habitats. The
springhead of Sarab Niloufar (Chenghai) village is in the form of a large pond, containing yellow water
lily. Sarab Niloofar has been studied during 2001 to 2017, visited regularly and evaluated based on
IUCN criteria. This species is considered as threatened species. The most important threat for this
species, is the discharge of sewage into the springhead that has caused the destruction and gradual
elimination of it. In recent years, it has been observed that aggressive species like as Phragmitis
australis, Sperganium erectum and Sorghum halepense threaten the habitat of Nuphar lutea and the
presence of species specific to the fresh and clear waters of the region have affected.
