Towards calcareous wetland creation in flooded abandoned aggregate quarries: A 3-year field mesocosm study

The purpose of this study was to demonstrate the feasibility of the rehabilitation of abandoned aggregate quarries to calcareous wetlands through a growth experiment at the quarry floor. We tested the effects of planting substrate (fine screenings, coarse rock, transplanted peatball, and topsoil addition to screenings) and springtime water depth (+15, 0, and −15cm relative to ground surface) on the growth of Carex aquatilis over 3 years. …
