Espécies arbóreas de Palmas atrativas para as aves

Abstract

Urban afforestation plays an essential role in conserving biodiversity and improving environmental quality in cities. This study aimed to identify the tree species most attractive to birds in the urban area of Palmas, Tocantins, with emphasis on those native to the Cerrado biome. The research, descriptive and analytical in nature, was based on secondary data from the Urban Afforestation Plan of Palmas, floristic inventories, and studies on urban avifauna. The species were evaluated according to their origin, frequency, and the type of resources they provide, such as fruits, seeds, and nectar. A total of 340 species distributed across 65 families were identified, the majority of which are native to the Cerrado. Species such as Myracrodruon urundeuva Allemão (aroeira), Anacardium humile A.St.-Hil. (cajuí), and Euterpe edulis Mart. (açaí) showed the highest number of bird interactions, attracting between 10 and 14 species. The interactions occurred predominantly with native trees, mainly involving frugivorous, granivorous, and nectarivorous birds, especially those from the families Turdidae, Thraupidae, and Psittacidae. The results highlight that native trees are more effective in attracting and maintaining urban birdlife, contributing to ecological balance and biological diversity. It is concluded that valuing native species in urban afforestation is fundamental for fauna conservation and for achieving the Sustainable Development Goals, particularly SDGs 11 and 15.
