ABSTRACT
Watershed scientists involved with the establishment of the Marcell Experimental Forest (MEF) had the foresight to initiate research on evapotranspiration (ET) of peatlands at the onset. Bay (1966) emphasized the need for such fundamental hydrologic studies because of the prominence of the 6.1 million ha of organic soils in headwater watersheds of the northern Lake States. Bay’s emphasis on ET was warranted given the dearth of research on evaporative losses from peatlands. Therefore, developing methods for determining ET in peatlands and peatland-upland forested watersheds became a key part of the research program at the MEF.
