Description
Summary:The achievement of qualitative analyzes of the urban trees is essential for it's maintenance because it allows to identify the main problems and to propose the possible solutions. Considering this situation, this work was carried out to evaluate the qualitative status of urban trees of 25 main streets of the Aracaju city, capital from Sergipe State, Brazil. The analysis were performed by means of a census, where all the individuals were quantified, identified and characterized in accordance with the following parameters: general state of the tree, general balance, plant health, intensity of mechanical injuries, ecological aspects, phenological events, interference generated by tree in the buildings, type of paving and root superficiality. It was also observed if the individuals had suffered some type of management and, subsequently, suggested the actions kind would be necessary for their adequacy. There were evaluated in total 3,595 individuals, distributed in 66 species. The most part of (46%) shown a general regular state, where the main problems observed were: tree pruning in the 31,2% of the individuals and insects xylophages (termites). The main problems observed were: cleaning pruning (32,2%) and the substitution of old and debilitated individuals (10,8%). Keywords: floristic composition; phyto-sanitary condition; pruning; urban streets. A realizacao de analises qualitativas das arvores plantadas no ambiente urbano e essencial para a sua manutencao porque permite identificar os principais problemas e propor possiveis solucoes. Dentro desse contexto, este trabalho foi realizado com o objetivo de avaliar o estado qualitativo da arborizacao das 25 principais vias publicas da cidade de Aracaju, capital do Estado de Sergipe. A analise foi realizada por meio de censo, no qual os individuos foram quantificados, identificados e caracterizados de acordo com os seguintes parametros: estado geral da arvore, equilibrio geral, aspecto fitossanitario, intensidade de injurias mecanicas, aspectos ecologicos, eventos fenologicos, interferencias geradas pela relacao arvoreconstrucao/fiacao, tipo de pavimentacao e superficialidade de raizes. Foi observado tambem se os individuos sofreram algum tipo de manejo e, posteriormente, sugeridas quais as acoes seriam necessarias para a sua adequacao. Foram avaliados no total 3.595 individuos, distribuidos em 66 especies. A maioria das arvores (46%) apresentou um estado geral regular de qualidade, sendo os principais problemas observados a poda drastica executada em 31,2% dos individuos e a acao de insetos xilofagos (cupins). Dentre os problemas observados, os principais sao a necessidade de poda de limpeza (32,2%) e a substituicao de individuos velhos e debilitados (10,8%). Palavras-chave: composicao floristica; fitossanidade; podas; avenidas.
