Padrão espacial e risco de extinção da ordem Piciformes no Brasil

Abstract

Faced with increasing anthropic pressures, studies that aim to know the conservation status of species become an important tool in combating biodiversity loss. In this sense, the present study aims to assess whether the Piciformes birds present in Brazilian biomes are at risk of extinction. Thus, 87 species were evaluated, taking into account the occupation of protected areas within the Brazilian territory and what is the percentage of the Piciformes species in protected areas. To do this, the Red List of Species prepared by the IUCN was used, as well as the use of geographic data also available on the site and the SALVE system, promoted by ICMBio. Through the maps of the species overlaid on the Brazilian biomes and protected areas, it was revealed that the largest occurrences of the species were in the Amazon and Atlantic Forest biomes, where there is also a higher percentage of protected areas. Furthermore, it was found that around 90% of the species are in the Low Concern (LC) category, however, attention is drawn to current public policies that put at risk the positive conservation status of these species.
