Abstract
Over the last 50 years, escalating biodiversity losses, coupled with persistent and intensifying pressures, have resulted in the extinction of species before their scientific description. The Brazil stands out as a country with a vast diversity of bryophytes, with consistent progress done in past years towards a complete assessment of its flora. However, major gaps still exist, making the conservation of this group challenging. In this scenario, automated tools that assist in species extinction risk detection emerges as crucial alternatives to accelerate the process of biodiversity protection. Thus, we highlight the initiative of the Brazilian conservation community to optimize and automate processes for calculating criteria and parameters needed to assess species extinction risk. Aiming to expedite the risk assessment and direct efforts towards truly threatened species, a list of endemics was created, with names accepted and validated by the backbone taxonomic of the Flora of Brazil 2020, and of broad occurrence, using the rapidLC method, totalling 100 species. The acquisition of occurrence records relied on databases such as Splink, JABOT, and GBIF. For a complete assessment, various biological data were extracted from available online databases, covering biomes, habitats, incident threats, among others. A web application development system was elaborated through the Shiny package of the R software, enabling the delivery of datasets to experts who validated determinations, confirming species distributions, and compiling biological data. The bryophytes were then assessed following the IUCN criteria, resulting in 48 species immediately assessed as Least Concern, while the remaining 52 were forwarded for continuous assessment, evaluated by the National Centre for Flora Conservation, Brazils National and Global Red List Authority. The use of these tools represents crucial steps in the creation of a consistent red list for Brazilian bryophytes, emphasizing the importance of expediting risk assessments, especially in megadiverse tropical regions like Brazil.
