This project aims to contribute to the conservation of the Hudsonian Godwit (Limosa haemastica), a long-distance migratory shorebird classified as Vulnerable, by assessing its use of the Lenga Wetland in south-central Chile and addressing the main threats affecting this critical habitat.
The Lenga Wetland is a peri-urban coastal ecosystem located in the Biobío Region that supports a high diversity of waterbirds and functions as an important stopover and non-breeding site along the Pacific Americas Flyway. Despite its ecological significance, the wetland is under increasing anthropogenic pressure, including habitat degradation, pollution, unregulated tourism, and disturbance from domestic animals.
The first main aim of the project is to generate baseline ecological data on the presence, abundance, habitat use, and seasonal dynamics of L. haemastica at the Lenga Wetland. Through standardized monthly bird surveys conducted over one year, the project will provide the first systematic assessment of this species at the site. These data are essential for understanding the role of Lenga as a stopover or overwintering area and for informing future conservation and management actions.
The second aim is to identify, characterize, and spatially map the primary anthropogenic threats affecting both the wetland and shorebird populations. By combining field observations with GPS-based mapping and GIS analyses, the project will document sources of disturbance such as waste accumulation, unleashed dogs, vehicle access, and recreational activities. This information will allow the prioritization of threats based on their intensity and reversibility and will support evidence-based recommendations for habitat protection and urban planning.
The third aim is to strengthen local conservation awareness and stewardship through community engagement, environmental education, and citizen science. The project will involve local schools, residents, and volunteers through participatory workshops, guided birdwatching activities, and training in basic bird monitoring techniques. By fostering local involvement and ownership, the project seeks to build long-term support for wetland conservation.
