In 2021, the Zostera noltei seagrass bed monitoring, located on the transitional water body FRFT08 Bidassoa (Txingudi Bay, Hendaye - Pyrénées Atlantiques), was carried out from a grid of 30 sample points ("stationary" monitoring) in the context of the Water Framework Directive. The "angiosperms" indicator established on this water body is based on 3 metrics (composition, extent and abundance). In 2021, the calculation of this indicator classifies the water body in "Very good condition". The significant increase of the seagrass bed area (from 1.9 ha in 2018 to 4.5 ha in 2020) explains this result.
