Chave de identificação baseada em caracteres vegetativos para a arborização urbana de Foz do Iguaçu - PR

Abstract

Interfaces and synergies that permeate the theme urban forestry have been increasingly observed carefully when devising a good urban planning and its environmental management as implemented. The constant updating of environmental legislation, the social appeal and coming benefits are factors that can not be disregarded or detailed in the projects. Among the limiting factors for a fast incorporation of these concepts in urban forestry is the entry of new professionals from different areas, which collide in the correct recognition and identification of the implanted species in cities. Based on the above this study purpose, to develop a key for identification dendrological , trees and shrubs, more representative, quantitatively, the urban trees of the city of Foz do Iguaçu - PR, from studies and using if the program description Language for Taxonomy (DELTA program). For the identification of plants dendrological several characters can be considered important, is the peculiarity or the character set associated, but it is important that they are easily recognizable. The data used in this study were collected by consulting the available literature and inserts field collected plant material, compiled into specific worksheets and entered the DELTA Program. 25 species were listed according to the criteria described, belonging to 24 genera and 16 different botanical families. After the development of a matrix of presence and absence, in which all analyzed characters and character states found were evidenced, the data were released in the DELTA program and applied the ‘key command’ to generate the key dendrological. The making key was successfully obtained indicating that the use of the DELTA Program makes the process much faster and more accurately than the traditional method of printed dichotomous key.
