Diversity Indexes Performance in the Tree-lined Street Composition

ABSTRACT In this research was analyzed the performance of diversity indexes facing different scenarios of composition with distinct species richness and uniformity, the influence of planting spacing in the determination of values of these indexes and the behavior of diversity data of a street tree inventory in relation to two scenarios of composition approximated to real data. It was noted that there is significant influence of increased planting spacing only for species richness indexes. There was significant differences between values of all indexes for the diversity scenarios elaborated. In the scenarios analyzed, the species richness indexes showed lower and more stable values than inventory ones and the evenness indexes showed higher values.
