Arid wetlands are vulnerable ecosystems affected by natural and human factors. Their study and conservation are limited by data scarcity and sampling bias. In a wetland of west-central Mendoza, Argentina (Leyes-Tulumaya streams), we explored the contribution of plant and vertebrate records from traditional scientific sources and citizen science. Of 270 recorded species, citizen science contributed the majority of records and unique species. Similarity between databases was greatest between citizen science and literature, with birds dominating among vertebrates. The vertebrate inventory stabilized over time, although estimated richness exceeded observed richness. Accumulation curves for plants did not reach asymptote, suggesting incomplete sampling. Positive spatial autocorrelation of records was detected, indicating data clustering in lagoons. The integration and joint analysis of data sources proved crucial to obtain a more complete and robust understanding of biodiversity and its spatial distribution. Citizen science contributions, in particular, expand databases in understudied arid ecosystems, complementing traditional methods and addressing spatial and temporal information gaps.
