| Abstract |
Here we present the results of the reforestation project in degraded areas of the Tarumá-Açu Watershed and the estimation of the CO fixation for the reduction of greenhouse gas emissions during the 20-year period. For each species analyzed after planting, during the period 2015-2019, the method used was participatory observation, where those involved analyzed the data in loco, recording, through photos, the development of seedlings in terms of growth, mortality and survival in order to replace the dead with others that could carry out the functions of environmental protection and minimize the degradation process of the area. It can be said that the management of the process was necessary due to the climatic changes that occur during the year, since the monitoring of the species occurred in March, the rainy season and August, the summer season, or different periods: complete and dry. The observation was part of the whole process, from the moment of requesting the seedlings to replace the dead ones, analyzing those that have a higher survival rate and those that need a closer monitoring, due to the mortality rate. The growth, mortality and survival rates of the species are highly variable. Each species has different characteristics, therefore, the data found present different percentages for species planted in the same area, either lowlands or igapó. In 5 years of topography of the species and data, it can be said that the plants gradually adapt to the adversities of the soil and climate. Planting seedlings in the field should preferably be carried out after 30 days of preparation of the pits. The planting procedure is the same as described above, needing to remove the package containing the seedling and only then insert it into the well. The pit is then closed with the soil pressing it, so that there is more contact between the seedling substrate and the soil. As a result of the first step of the experimental methodology, with the participation of the community, students and volunteers, a brochure on how to care for the environment was distributed free of charge, illustrated by the Amazonian fauna, existing in the area, in schools and the community, at the end of each conference on environmental education.
