Flyway Site Network
During migration, water birds rely on a system of highly productive
wetlands
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The ...
to rest and feed, building up sufficient energy to fuel the next phase of their journey. International cooperation across their migratory range is therefore essential to conserve and protect migratory water birds and the habitats on which they depend.
East Asian-Australasian Flyway Partnership (EAAFP) identified 1060 sites as internationally important for migratory birds.
These sites are called the Flyway Site Network. The sites are expected to collaborate with the local community to preserve the wetland by raising awareness regarding the importance of the site, carefully documenting the number of migratory bird populations, and strictly monitoring the vegetation condition within the site.
Threats faced by migratory birds in EAAF

, but many of these natural habitats are either converted to agricultural land or threatened by drainage.
In response to the damage of wetlands and forests, many countries have implemented new forestry policies. An example of this is China's Natural Forest Protection Plan, which is expected to increase forest cover in eastern and southern China.
Hunting
Another major threat faced by migratory birds in EAAF is rampant hunting in South-East Asia. Reasons for hunting vary, but pet trade and hunting for food in rural areas are the most common motives.
As a result of the unregulated hunting, the
Yellow-breasted Bunting, whose IUCN threat status was "Least Concern" 10 years ago, has now been listed as "Vulnerable". In parts of

Conservation Priorities
According to a holistic review of current research, the demographics, habitat distribution, and survival rate of many endangered species remain ambiguous. Studies about these areas in the key habitats along the flyway may prove useful to conservation of migratory birds.
Besides, the current Flyway Site Network mainly focuses on water birds, neglecting the protection of remained migratory birds. Scientists claim that organizations and laws focusing on protecting these birds may be needed.
Roles of Birders
The birding community in Asia is increasing rapidly, especially in China, Thailand, Indonesia, and Philippines, due to a growing middle class. Despite language barriers, the
e-bird system has successfully assisted birding communication across national boundaries, contributing to the development of EAAF. For example, the collective data from birders have contributed to many research projects, such as filling the gap of distribution of the
Rufous-Headed Robin
