In 2011, the IUCN Species Survival Commission and IUCN Asia Regional Office commissioned an independent report to assess the state and condition of intertidal habitats along the East Asian-Australasian Flyway (EAAF), in response to growing concerns expressed by IUCN members over observed declines in biodiversity, the loss of ecological services, and an increase in ecological disasters. The report is a situation analysis, and it seeks to gather in one place the relevant data and analyses, and to present as clear a picture of the status of the intertidal zone in the EAAF as the data allow. By intention, the resulting report makes no recommendations, but it should serve as a resource for those stakeholders empowered to make or influence decisions and policies in the region. You can download and read the report here.
