Cut/remove/thin forest plantations and rewet peat
A replicated, paired, site comparison study in 2003–2007 in nine bogs and fens in Finland (Noreika et al. 2015) reported that areas restored by tree thinning and rewetting had moss cover and tree structure intermediate between degraded (forested and drained) and natural (sparse trees, never drained) areas. After 1–3 years, restored areas had greater Sphagnum moss cover but less cover of other mosses than degraded areas, but less Sphagnum moss cover and greater cover of other mosses than natural areas. Restored areas had fewer tall trees (>3 m) than degraded areas, but more tall trees than natural areas. All data were reported as graphical analyses and differences were not tested for statistical significance. Between 2003 and 2006, in each of nine degraded peatlands, one area was managed by removing excess trees (above the natural tree density) and blocking drainage ditches. In each peatland, one degraded and one pristine area were also monitored. In 2007, vegetation cover was visually estimated in twenty-four 1 m2 quadrats/area (72 quadrats/peatland). Trees were counted and measured in six 100 m2 plots/area (18 plots/peatland). This study was based on the same experimental set-up as (11).
