The Mount Wellington string bog, Tasmania

Abstract

A string bog ecosystem occupies part ofasubalpinevalleyon Mt Wellington, Tasmania. The steps in the subsurface biockstream preferentially underlie pools Variations in pool hydrology are independent of pool size. There is a correlarion between pool sbape and pool type, an oval sbape being indicative of more recent secondary pool formation, primary pools with rocky floors being variably shaped. Variation in the bog vegetation is closely related to variations in slope, drainage and peat depth. The major changes in abundance of pollen types are relared to changes in abundance of charcoal. The Mt Wellington string bog complex appears likely to have been formed by similar processes to those postulated to bave resulted in the string bog system at Mt Field.
