Abstract

SILVA FILHO, Demóstenes Ferreira da  and  BORTOLETO, Silvana. Use of diversity indicators in a street arborization management plan for aguas de Sao Pedro - SP, Brazil. Rev. Árvore [online]. 2005, vol.29, n.6, pp. 973-981. ISSN 0100-6762.  http://dx.doi.org/10.1590/S0100-67622005000600017.

Few Brazilian cities have an effective planning for street arborization, comprising the objectives to be achieved and possible qualitative and quantitative goals. Another problem of Brazilian cities is the low species diversity, prevailing species homogeneity, which may lead to great losses of trees due to the incidence of specific pests or diseases. The richness or diversity indexes are useful as diversity indicators and can be useful in management decision making. The Shannon-Wiener and the Odum indexes were evaluated by means of carrying out a street census in Aguas de Sao Pedro Resort. Maximum and minimum diversity indexes were calculated, allowing the quantification of species and number of trees in each street, providing the foundation of a management plan, which included the introduction of new species and new individuals, removal of trees and intervention priorities.

Keywords : Diversity; urban forestry; criteria for street arborization.
