Add mosses to peatland surface
A replicated before-and-after study in 2004–2009 and 2011–2013 in two bogs in Germany (Gaudig et al. 2013) reported that plots sown with Sphagnum moss fragments (then mulched) developed high Sphagnum cover. Before sowing, plots were bare peat. In one bog (Ramsloh), papillose bog moss Sphagnum papillosum reached 92% cover four years after spreading. In the other bog (Rastede), blunt-leaved bog moss Sphagnum palustre had reached 97% cover and papillose bog moss 91% cover two years after initial spreading. In 2004 (Ramsloh) and 2011 (Rastede), fragments of single moss species were spread onto 60–224 bare peat plots (15 x 15 or 25 x 25 cm). At Rastede, gaps were filled with additional fragments one year later. All plots were mulched with straw and a high water table was maintained. Sphagnum cover was estimated in each plot 1–3 times/year.
