Abstract
Unplanned Urban Growth and Its Potential Impacts on Bird Species in a South American City
Highlights
Urban landscapes are expanding at accelerated rates, especially in underdeveloped and tropical countries (United Nations, 2018)
A total of 126 bird species were registered in the Isidoro Forest (106 species during fieldwork and 20 species observed only during the study of Environmental Impact Assessment (EIA)), distributed among 38 families
The unplanned urban expansion reduced more than 20% of the grassland area in relation to its previous coverage in 2012, which is the preferred habitat for more than 65% of the bird species recorded in Isidoro Forest
Summary
Urban landscapes are expanding at accelerated rates, especially in underdeveloped and tropical countries (United Nations, 2018). Peri-urban regions typically harbor greater amounts of natural vegetation cover and contain reduced human population densities than urban areas, which allow the presence of higher species diversity (Canedoli et al, 2018; Snep et al, 2006). This relationship is related to the reduction and loss of resources and habitats that are essential for the maintenance of several species found from peri-urban to urban areas, such as the loss of large and old trees which are necessary for reproduction as well the daily activities of some bird species (Le Roux et al, 2014; Stagoll et al, 2012).
