Fig. 2From: Paludification reduces black spruce growth rate but does not alter tree water use efficiency in Canadian boreal forested peatlandsSchematic representation of the three sites along the study transect. Relative altitude of the organic layer (green) and the mineral surface (grey) are shown. Black rectangles represent the location of the sampled peat cores. The dotted blue line indicates the depth of the water table measured in the field. Trees are not to scale but are representative of variations in canopy openness along the transectBack to article page
