Faunistic inventory of an urban stretch under the influence of the Saboó River - Santos – SP. Sandra Regina Pardini Pivelli

Abstract

The city of Santos is an area under strong human pressure and, even before the first half of the twentieth century, experienced significant impacts resulting mainly from rapid urban and port expansion. The environment of the study area presents intense truck traffic, since it is the only access to the Port of Santos. The remaining vegetation consists of an adjacent mangrove swamp and a mosaic of secondary vegetation located in stretches parallel to Avenida Engenheiro Augusto Barata, predominantly in the initial stage of succession, composed of exotic and native species of restinga. The objective of this study was to inventory terrestrial and aquatic fauna (reptiles, birds and mammals) in a linear course of 1.2 km under the influence of Rio and Saboó Lagoon. The method used was the transect method, with occasional stops to better identify some of the species. The inventory was based on direct observations using binoculars and footprints. The identification was made through visual and auditory contacts. The field studies occurred in April 2018, totaling 30 hours at times favorable to observation, which included mainly bird life. Two species of reptiles, sixty-three birds and three mammals were found. Six endemic species, two endangered species and one almost endangered species make up the richness of avifauna. Despite the high degree of anthropization and historical degradation of the area, there are still very generalist species that use the aquatic environments in the region as areas of shelter, food, shelter, rest and reproduction, demonstrating the need for their conservation.
