Inventário florestal arbóreo na cidade de Dourados

Abstract

The bigest current challenge of public management with regard to urban afforestation lies in the fact that there are many conflicts of interest when it comes to the maintenance of tree individuals, especially in commercial centers, as there are several public facilities that compete for spaces that must be occupied by afforestation. If on the one hand there are many ecological and environmental gains when the presence of arboreal individuals, on the other hand there are losses mainly to the economic sector that visualize a tree as a competitor of their enterprise. Other conflicts are related to urban infrastructure as well as accessibility. In this way, the urban afforestation that should provide advantages, ends up generating inhospitable condition for the population, being the target of several actions of depredations and vandalism. The objective of this work is to present the results of the arboreal inventory of the Marcelino Pires Avenue in the city of Dourados, especially in the central region, and to evaluate the pressure on these individuals by the various interests, in addition this work shows the various problems arising from the implantation of urban afforestation without proper planning. In this paperwork the total population of trees that were inventoried, totalized 1020 individuals distributed in 63 species. The most frequent species found were: Caesalpinia peltophoroides (Sibipiruna), Roystonea sp (Palmeira), Licania tormentosa (Oiti), Caesalpinia ferrea (Pau ferro), Lagerstroemia indica (Resedá) and Tabebuia sp (Ipê), these five species together represented 61.9% of all the Tree population inventory. The parameters evaluated were: CAP, DBH, total height, stem height, trunk shape and injuries, crown diameter, crown interference, presence of pest and diseases and type of pruning, location, root interference. The species that had the highest percentage of interference with the urban infrastructure was Caesalpinia peltophoroides (Sibipiruna), where 100% of the individuals presented some kind of treetop interference.
