SUMMARY:

The search for new information about the Brazilian Merganser Mergus octosetaceus is crucial for establishing strategies that support guidelines and policies within the scope of the species conservation biology. The premise of this study was based on insufficient data and a lack of understanding of the real distribution of the species in the Chapada dos Veadeiros region, Goiás (GO). The following studies were carried out: mapping and current distribution of the Brazilian Merganser in the Chapada dos Veadeiros region, survey of the environmental situation in land use and the main treats for the Brazilian Merganser in the Tocantinzinho River Basin; and participatory mapping through Social Hydrocartography of Brazilian Merganser in 24 traditional communities in the Chapada dos Veadeiros region. The main results of the mapping were the delimitation of the distribution area in 77% of the Pouso Alto State Environmental Protection Area. The population estimate of the species in this region is approximately 70 adult individuals, where ten stretches of rivers occupied by couples of the species were identified, in five main rivers in the study area, identification of 13 reproductive sites and two new active nests, which subsidized the Integrated Population Management Program, with the collection of eggs for breeding in captivity. The results of the survey of the environmental situation of land use and the mapping of the main threats to the species in the Tocantinzinho River sub-basin demonstrated that records of the species occurred in relatively preserved areas, but with a low percentage of protection (6.48%) for the basin as a whole. Seven hydroelectric projects were identified for this river basin and it was also verified that several large monocultures predominate on the plateaus between the hills of the main tributaries of the basin and that there are no environmental protection measures or UCs in the areas to the south. The conclusion is that the conservation of the species in the basin depends mainly on prohibiting the installation of hydroelectric projects, mitigating the impact of already installed agro-industrial parks and controlling the suppression of native vegetation. In characterizing the 24 traditional and nontraditional communities, their relationships with water and surveying the main socioenvironmental impacts present in these communities in the Chapada dos Veadeiros microregion, it was detected that the reduction in flow is the main water problem in this region. The results observed confirm that agricultural activities and deforestation are the main impacts in this territory, contributing to the worsening of the climate crisis. The need for participatory mapping is evident to understand the processes and dynamics in these territories, give voice and visibility to communities, equip them to defend their identity, and encourage everyone's participation, with autonomy. Social Hydrocartography was used to mobilize capabilities for the conservation of natural environments, with the Brazilian Merganser as the flagship species.
