BIRD BIODIVERSITY IN THE COASTAL ARTIFICIAL LAGOON "LA MANSION", LIMA (PERÚ)

Abstract

Because the study of bird communities provides a fast, reliable and replicable means of assessing the conservation status of most terrestrial and aquatic habitats, the present study aimed to know diversity, specific richness, composition and Identify the species currently present in the Laguna de la Mansion in order to generate useful information for future planning and conservation of these. This place of study is a small artificial ecosystem located in Lima, Peru. The method used was the transect by strip and direct observation, adapting the method according to the terrain, size and type of ecosystem, in this way five transects were established where the observations were made during three shifts the months of April and May 2019 Birds of six families were registered (Ardeidae, Columids, Phalacrocoracidae, Tyrannidae, Rallidae and Anatidae), eleven species were identified and 283 individuals were counted; being the specific wealth of the most predominant species, the Nycticorax nycticorax, 37.10% while the species with less presence were: Gallinula chloropus and Anas platyrhynchos being their percentages of 0.71% each. A total of 53 nests were also recorded, of which 14 are believed to be active and most belong to the Nycticorax nycticorax species. The Shannon and Simpson formulas were applied for the diversity of species in this ecosystem, obtaining that the value of the diversity of this ecosystem is 3 (Shannon) and there is a high probability (74%), according to Simpson's formula, that the First two randomly chosen species are the same. From the study carried out, it was concluded that the biodiversity of the La Mansion lagoon is of considerable abundance, in addition, it serves as a refuge for birds within the context where natural lagoons are modified, altered and destroyed, which is why the importance of preserve it and take care of it.
