Panorama da arborização urbana no Brasil e dos recursos florais oferecidos para a manutenção das abelhas

Abstract

Urban forestry has a primordial role in the quality of life and environmental comfort of its inhabitants. In Brazil, the discussion about planning afforestation has been growing in recent years, although synchrony with ecological aspects is still quite outdated. Therefore, this study aimed to present an updated of urban forestry in Brazil through a survey of the country's capitals. For this, afforestation manuals, master plans and afforestation guides from Brazilian capitals were consulted, resulting in more than 400 indicated species from 70 botanical families. Among the most indicated species, predominate species from seven families, with the genera Handroanthus and Tabebuia being the most indicate in Brazilian capitals. The results demonstrate that the official documents consulted are outdated and the also a low diversity of indicated species. The floral visitors for the indicated species belong 23 genera of bees, the majority being large bees of Apinae subfamily. The data show the need to diversify of species used in urban afforestation in Brazil and the inclusion of information regarding the floral resources. Finally, it is necessary to promote discussions that allow the inclusion of information about floral visitors in afforestation manuals. The diversification of tree species will promote the maintained of pollinators and the same time will help the health of plant species.
