Poor fen : ウィキペディア英語版
Poor fen

A poor fen (also known as transitional bog, transitional mire or sedge mire) is a natural wetland habitat, consisting of dense low growth of small sedges and other plants. It develops on wet ground where the water is fairly acidic and has very few plant nutrients.
Poor fen is intermediate between the taller vegetation of fen, which occurs where the water is much less acidic, and the short, mossy vegetation of bog, which is even more acidic.
==Ecology==
Poor fen is found where the ground is permanently wet with nutrient-poor water which is somewhat acidic. For example it occurs as the vegetation of flushes (marshy springs on slopes), in places where neutral water enters more acidic bogs, in wet acidic grassland, and sometimes in the flatter parts of flood-meadows where much of the water is ombrotrophic (derived directly from rainfall). It sometimes forms a floating mat over water or very wet peat, making a mobile surface known as quaking bog.
Poor fen is usually grazed by wild animals or livestock, which prevent ecological succession into wet woodland.
