Abstract

The study of the floristic diversity of street trees and the concerns of the population is conducted in Brazzaville. The theme is oriented on the place and the interest of the trees of alignment in the urban development. The methodology is based on the systematic counting of woody trees with a diameter at breast height (dbh) ≥ 10 cm, of 32 arteries selected according to the number of trees in the line and the degree of urban development. The concern of the populations is informed via a questionnaire whose informants are selected following a non-probability sampling for convenience. The floristic inventory lists 1867 woody trees organized into 42 species, 32 genera and 16 families. The allochthonous portion dominates a flora with senescent individuals (Terminalia mantaly, Millettia laurentii, Pithecellobium dulce, Albizia lebbeck) and of dbh ≥ 70 cm. Despite a dominance of Fabaceae and Combretaceae, the biodiversity indices reveal a low degree of diversification whose equitability of taxa supports floristic similarity between boroughs. In terms of concerns, while there is unanimity about the ecosystem goods and services derived from avenue trees, the choice of taxa reveals divergences correlated with socio-professional categories. Finally, the poor practice of street trees in urban development gives a negative opinion of this stand with regard to the disservices caused to roads and structures. The roles and functions of the tree being recognized by all, the increase of the woody cover based on local species is desired in order to serve as a reservoir of biodiversity and fulfill the educational action, while underpinning the satisfaction of the daily needs of the populations.
