Rewet peatland (raise water table) Peatland Conservation

A replicated before-and-after study in 2010–2013 in three degraded raised bogs in Latvia (Priede 2013) reported that rewetting had no effect on vegetation cover after one year. These results were not tested for statistical significance. In all three monitored sites, vegetation cover was similar in the three years before rewetting and the year after rewetting. This was true for heather Calluna vulgaris (before: 51–61%; after: 48–60%), Sphagnum mosses (before: 18–30%; after: 19–28%) and three other moss species (3–16% before and after). In 2012, drainage ditches were blocked in three degraded bogs. Each year between 2010 and 2013, vegetation cover was visually estimated in 25–30 permanent quadrats/bog. Quadrats were circular (4 m diameter) and arranged along transects perpendicular to the blocked ditches.
