Levantamento florístico das espécies de plantas daninhas do Projeto de Agroecologia Urbana - ECOINEC

Abstract

This study aimed to characterize the weed community in managed and unmanaged areas of an agroforestry system implemented at ECOINEC, Fortaleza-CE. Sampling was carried out using systematically and randomly distributed plots, followed by taxonomic identification and calculation of phytosociological parameters. The managed area showed greater species diversity, but with a strong dominance of purple nutsedge (Cyperus spp.), which presented the highest values of frequency, density, and abundance, reflecting its high capacity for of buffelgrass (Cenchrus ciliaris), a perennial and highly competitive species, responsible for reducing local diversity. The comparison between the areas highlighted the direct impact of management on the structure of the weed community. The results reinforce the need for integrated management practices to minimize the dominance of aggressive species and promote greater ecological balance in agroforestry systems.
