ericaceous shrub bog
- Ericaceous Shrub Bog
Sites in Alaska on wet peaty soils on which ericaceous shrubs are co-dominant with sedges, mosses, other shrubs, or trees.
When present, they provide less than a quarter of the cover.
Peats may be either sedge or sphagnum, with accumulations ranging from 15 cm to 12 m. The lowest peat accumulations are in interior and arctic Alaska (although some substantial peat deposits are also present in these areas); the deepest are in southeast Alaska.
Sphagnum is usually present, whether or not it is the primary peat former. These bogs are usually acid. The surface is usually hummocky and standing water may be present in depressions, especially in early summer.
Surfaces tend to be drier than wet meadows and water tables may drop to several centimeters below the surface during dry spells.
Peat-floored ponds one to several meters across are common in some bogs in Prince William Sound and southeast Alaska.
Mosses are present, and lichens (frequently), although they are usually not important.
Upright shrubs like willows and alders may be either absent or common (though less than 25% of cover).
Aquatic plants are absent or sparse.
For more, look up "Fen", or "Mire". Good luck with that.
Among bogs, the Ericaceous Shrub Bog is the most ericaceous while remaining shrubby and yet preserving its essential Bog-Nature. So go there.
