SummaryWe present an assessment of the Southern Paraguayan Grasslands using Important Bird Areas (IBAs) located in a grassland landscape mosaic. Eleven IBAs in southern Paraguay were evaluated 10 years after their designation, using the BirdLife International method to assess the state, pressure, and response of these areas, during 2017 and 2018. Overall, the Pressure from ecosystem modifications led by fire, and fire suppression, agricultural expansion, and intensification due to farming and grazing have been identified as the major threats to IBAs. Regarding the State, 64% of the IBAs presented Very poor habitat quality to support grassland bird communities. The level of conservation Response was mostly negligible when considering conservation designation, management planning and conservation actions for the trigger species. Our results provide useful information to partners to reconsider these areas as IBAs as most of them no longer fulfill international requirements, we also highlight the importance of strengthening national policies to adequately protect natural grasslands.

巴拉圭南部草原重要鸟类区 (IBA) 的评估

摘要我们使用位于草原景观马赛克中的重要鸟类区 (IBA) 对巴拉圭南部草原进行了评估。巴拉圭南部的 11 个 IBA 在其指定 10 年后接受了评估，使用国际鸟类保护协会的方法来评估这些地区在 2017 年和 2018 年期间的状态、压力和反应。总体而言，压力火灾和灭火导致的生态系统改变、农业扩张以及农业和放牧导致的集约化已被确定为 IBA 的主要威胁。关于状态，64% 的 IBA 表示栖息地质量非常差，无法支持草原鸟类群落。保护水平回复在考虑触发物种的保护指定、管理规划和保护行动时，几乎可以忽略不计。我们的研究结果为合作伙伴提供了有用的信息，以将这些地区重新考虑为 IBA，因为它们中的大多数不再符合国际要求，我们还强调了加强国家政策以充分保护天然草原的重要性。
