Diagnóstico da Vegetação na Microbacia do Córrego Monjolo (Chapada dos Guimarães – MT) a partir do Método Verah

SUMMARY

A vegetação ciliar é extremamente importante para a proteção dos cursos de água, os efeitos causados pela eliminação desta vegetação podem ser: o assoreamento dos córregos e rios; deslocamento e desaparecimento de nascentes, da fauna aquática e terrestre; agravamento das secas e das cheias e escoamento direto de resíduos de áreas mais elevadas diretamente para a água. Nesse contexto, este trabalho decorreu da necessidade de ações urgentes voltadas ao controle da problemática ambiental constatada na microbacia do córrego Monjolo, no município de Chapada dos Guimarães, Estado de Mato Grosso. O objetivo do trabalho foi delimitar e caracterizar a vegetação existente na microbacia do córrego Monjolo, diagnosticar os problemas ocasionados pela supressão da vegetação e recomendar soluções. Essa microbacia é um importante curso de água para esse município, pois cerca de 60% da captação de água para o abastecimento urbano provém dele. A pesquisa utilizou o método VERAH (V = Vegetação; E = Erosão; R = Resíduos; A = Água e H = Habitação). Inicialmente, ocorreu o reconhecimento da microbacia em campo, posteriormente, houve o levantamento e a identificação das espécies vegetais, e foram divididas em nativas do cerrado, exóticas e frutíferas/paisagísticas. Sete problemas relacionados à falta de vegetação foram apontados na área da microbacia, esses foram diagnosticados e, finalmente, elaborado o diagnóstico da microbacia. Existe a necessidade de um plano de ação que garanta a conservação desse recurso hídrico, algumas dessas ações começam pela recomposição da mata nativa, em alguns locais e elaboração de projetos educativos e de sensibilização, sobre a importância de conservar os recursos naturais. Palavras-chave: Vegetação.

In this context, this work was due to the need for urgent actions aimed at controlling the environmental problems observed in the Monjolo stream watershed, in the municipality of Chapada dos Guimarães, Mato Grosso. The objective of this work was to delimit and characterize the existing vegetation in the Monjolo stream microbasin, to diagnose the problems caused by the suppression of vegetation and to recommend solutions. This microbasin is an important watercourse for this municipality, because about 60% of the water abstraction for urban supply comes from it. The research used the VERAH method (V = Vegetation, E = Erosion, R = Residues, A = Water and H = Housing). Initially, the microbasin was detected in the field, later the plant species were collected and identified, and they were divided into cerrado, exotic and fruitful/landscape native species. Seven problems related to the lack of vegetation were pointed out in the area of the microbasin, these were diagnosed, and finally the microbasin diagnosis. There is a need for a plan of action that guarantees the conservation of this water resource, some of these actions begin by recomposing the native forest in some places and elaborating educational projects and raising awareness about the importance of conserving natural resources. Keywords: Vegetation. Water Resources. Urban Microbasin. Sustainability.
