Summary
Published in International Peat Journal 10: 3-12
Water table levels were monitored before and for three consecutive years after clear-cutting on eight forested wetland sites. The water table rose significantly after clear-cutting by 13 and 5 cm on wet mineral and organic soil types, respectively. Water table rises were larger on mineral soils than organic soils because the deeper water tables of the mineral soils fluctuated in soil layers of lower drainable porosity. In mineral soils, the frequency of water table levels reaching the top 20 cm rose from 25% in the forest to 68% in the clear-cut. The rainfall interception rate dropped from 31% in the forest to 10% immediately after clear-cutting with a slow rise to 14% three years later in spite of a plant coverage of 50%. Links between vegetation cover and the gradual drawdown of the water table could not be established over the three year study because of the large seasonal water table variability.
