Subsidence rates of peat since 1925 in the Moanatuatua swamp area

TR 2004/17

Report: TR 2004/17

Author: Stewart McKenzie, Malcolm McLeod, Landcare Research

Abstract

Moanatuatua Swamp is one of many peat bogs in the Waikato region that has been drained and converted to agriculture or horticulture. As a result of conversion, subsidence occurs from consolidation and losses of organic matter, due to peat mineralization (Schipper & McLeod 2002). Obtaining information on subsidence rates is important for future land-use management and the developing of mitigation strategies to reduce subsidence rates and CO2 emissions.
