Big Meadow Bog Restoration
Design and Construction
2015 - Present
ECA was retained by the Eastern Mountain Avens Recovery Team to complete the hydrologic restoration design for the 58 ha Big Meadow Bog. The Eastern Mountain Avens (Geum peckii) is a globally endangered plant found only in two locations in the world, one being Big Meadow Bog. Ditching and draining of the bog in the late 1950s led to the lowering of the water table, with adverse impacts to the Aven's population and ecology of the bog.
ECA undertook field evaluations of impacts; a ditch-blocking trial to gather empirical data on water levels; and an assessment of historic site changes in order to develop a phased restoration design. Prescriptions included of 120 peat based ditch blocks, 3.7km of ditch re-profiling, and removal of woody plants as measures to restore hydrology and reactivate historic lagg channels. Restoration began in the spring of 2016 and was completed in the fall of 2017.
