3,807 nesting waterfowl species recorded

Ghardaia

Ornithologists at the wilayas of Ghardaïa and El Meneaâ have enumerated a waterfowl population of 3,807 waterfowl nesting during the current May-June period in the wilayas of Ghardaïa and El Meneaâ, we have learned on Thursday from the Forest Conservancy. observers (RNOOA), on the occasion of World Migratory Bird Day, the national census of nesting migratory waterbirds, targeting natural and man-made wetlands of two species of wilayas, which have become privileged nesting sites for volatile migratory populations, it showed.
These aquatic areas have become “essential nesting stops for migratory birds on the migration axis between Africa and Europe”, especially the “Sabkha El Maleh” natural wetlands ( El Meneaâ) and the artificial wetland “Kef El Doukhan” (Ghardaïa), the leader of the Southeast II group of the network, Abdelwahab Chedad, explains.
The goal of this metric, taken annually from May 17 to June 5, 2022, is to “establish a baseline for monitoring different wetlands, to know the size of breeding bird populations.” in its area, morphology, density”, Mr. Chedad said, noting that evidence of reproduction is determined by the existence of nests, eggs, and chicks at sites. This number enables you to list 23 proven nesting bird species, including dominant species such as the Greater Flamingo, Moorhen, Black-winged Spider, Curling Stork, Common Stork, Black-winged pistil, Marble Marmaronette, Eurasian Stork, White Stork, mallard, he noted.
This census targets natural wetlands of world importance classified in 2004 under the Ramsar convention, “Sebkhat El Maleh” lake and unclassified natural wetlands. “Fayget El Gara” in the municipality of Hassi El Gara (wilaya El Meneaâ) as well as natural wetlands “Dayet Oum Souid” in Mansoura commune, and artificial wetlands created through a water treatment program waste management, environmental conservation and water resources including essentially the wastewater treatment plants (STEP) of “Kef Dokhen” (the output of M’Zab wadi) in El Ateuf, of Berriane and Guerrara as well as the the discharge of Metlili and Zelfana in the wilaya of Ghardaïa, he points out.
These wetlands have considerable biodiversity and are home to many species of migratory birds, some of which are on the endangered bird species list issued by the International Union for Conservation of Nature (International Union for Conservation of Nature). IUCN) released.
These aquatic sites, especially the man-made sites that exist within two forests, have become habitats and breeding grounds for bird populations, favored for their guarding and distanced from areas urban. They nurture the potential to potentially promote ecotourism and also to become a veritable open-air laboratory for scientists and other biologists.
Members of the national network of Algerian entomologists (RNOAA) noted this year a “clear” decrease in the number of breeding birds in natural and artificial aquatic areas in Ghardaïa. and El Meneaâ compared to the 2020 census with 6,135 animal subjects and the end of 2021 with 4,988 volatility subjects.
This decline in nesting birds is explained by proven global warming, drought and drying up of many aquatic sites, as well as human activities that have significantly impacted the ecosystem. fauna and flora ecology, according to the team leader of the national network of ornithologists who are also responsible for the office of plant and animal protection in the Ghardaïa Forest Reserve.
Mr. Chedad concludes that the presence of birds is a good indicator of the state of local biodiversity, despite heat waves, water stress and sandstorms.
