Recuperação de nascente na bacia hidrográfica do Rio Saltinho, em Imbaú-Paraná com participação da comunidade

Abstract

The present study aimed to carry out the environmental recovery of a degraded spring, located on a rural property in the municipality of Imbaú-PR, by planting seedlings of native trees in its surroundings. The action had the participation of the local community, as a way of contributing to participatory management in the conservation of water resources and the environment in a sustainable way. To this end, field surveys were carried out in order to investigate the different uses of the land on the property and also to define possible strategies for the recovery of the degraded APP. A mapping of the area was made and with the aid of the Arcgis 1.0 software, the use of the land was analyzed for the different agricultural activities developed on the site. In parallel to this, and based on law 12.651/2012 that instituted the Law of Protection of Native Vegetation, the limits of the APP to be recovered with planting of tree species were defined, and a project for the recovery of the area was also prepared. The rural landowners received the project with technical guidance and the methodology to be adopted for the rehabilitation of the spring and full development of the newly planted forest. With the support of the Social Forests program, the local community, and the departments of environment, agriculture, and municipal development, an environmental awareness campaign was held in which participants had the opportunity to voluntarily participate in the planting of 207 seedlings of native species of local flora around the spring. During the monitoring activity, the mortality of 30 less resistant species that are poorly adapted to climate variations was observed. The significant interference of exotic grasses was also observed, which is a limiting factor in the rehabilitation process of the area due to competition for nutrients. The practical environmental recovery activity, combined with social involvement, aimed to train human resources to disseminate knowledge in order to make them multipliers of the concepts, techniques in relation to the importance of the recovery of degraded areas, climate change, and the conservation of native vegetation and its associated natural resources.
