õhukese turbakihi (<30 cm) ja nõgusa pinnaga liigniiske tasandik, mis toitub mineraalainerikkast põhja- ja pinnaveest ja on seetõttu liigirikka taimestikuga
type of mire having flat concave surface and thin (<30cm) peat (deposit of dead plant) cover, which gets its water mainly from ground and surface water having thus diverse plant community. Over time and through the peat accumulation mire changes to ombrotrophic (obtains most of its water from rainfalls) with convex surface.
Hea teada
