Restoration of peatland by spontaneous revegetation after road construction
Abstract Questions Spontaneous revegetation from indigenous soil was used as a restoration method for peatlands degraded during road construction in northern Norway. We examined how plant community properties responded to the restoration, and which environmental factors affected the restoration succ...

Location Restored peatlands along roadsides at E10, mainland connection to the Lofoten islands, northern Norway. Methods The restored area originally consisted of poor to intermediate Sphagnum‐ dominated natural peatlands. Restoration consisted of stripping and stockpiling the topmost (30 cm) peat. The peat was stored for 1–2 yr before redistribution, with no further hydrological management. We conducted first time analyses of plant community properties 8 and 9 yr after restoration.

Undisturbed peatland was used as target for successful restoration. We used CCA and ANOVA to test the effect of restoration on species composition and richness.
