SUMMARY:

The vulnerability of high-altitude wetlands intensifies the negative impacts resulting from unregulated exploitation, underscoring the importance of adopting environmental management strategies. Accordingly, this study aimed to assess the conservation status of springs and propose environmental restoration techniques that contribute to biodiversity conservation and the maintenance of water quality and availability. This assessment was supported by analyses of environmental, physicochemical, microbiological, floristic, and phytosociological conditions of six springs located within a high-altitude wetland area. Macroscopic evaluation indicated that 50% of the springs exhibit a high degree of preservation (Class A), 33.33% are in poor conservation condition (Class D), and 16.67% are in a severely degraded state (Class E). Despite differences in preservation status, all springs showed signs of contamination risk. Physicochemical and microbiological analyses revealed significant variation in water quality across all sampling points, indicating that none of the samples fully met the potability standards established by Ordinance GM/MS No. 888/2021. Contaminants such as organic matter, nitrogenous compounds, and metals were detected at concentrations exceeding permissible limits, posing a threat to public health. Floristic and phytosociological analyses indicated a predominance of native species in Area 3 (spring 6), which was the only one among the six springs evaluated to exhibit characteristics consistent with the legal criteria for Permanent Preservation Areas (PPAs). Area 1 (spring 4) and Area 2 (spring 5) presented a higher number of exotic species, reinforcing the ecological importance of remnant vegetation cover for ecosystem maintenance. Land use and land cover analysis demonstrated urban and agricultural expansion over areas previously occupied by native vegetation. The results highlight the urgent need for integrated monitoring strategies, educational initiatives, and investments in sanitation infrastructure, aimed at conserving water resources, mitigating environmental impacts, and promoting the sustainability of spring ecosystems.
