Tidal Flat / Mudflat
Definition
Tidal flats are low-lying coastal sediment zones alternately submerged and exposed by the tides, ranging from mudflats to sandflats. They are among the most productive ecosystems on Earth: their invertebrate-rich sediments fuel the flyways of tens of millions of migratory shorebirds (the Yellow Sea flats being the critical refuelling stop of the East Asian–Australasian Flyway), while filtering nutrients, storing blue carbon and buffering coasts against storms and sea level rise.

Overview
How it is used
The ecosystem structures flyway conservation, coastal squeeze analysis, blue carbon accounting and the coastal defence case for habitat preservation.
Why it matters
Tidal flats are the airports of the bird world; losing them strands entire flyways — a reminder that the least photogenic habitats can be the most critical.
