abstract = {Abstract: In Lower Saxony, a state in northwestern Germany, ombrotrophic milled peatlands (bogs) have been restored over the last 40 years. In 2014 19 rewetted areas of industrially harvested raised bogs in Lower Saxony, Germany, were surveyed to see to what extent Sphagnum mosses spontaneously recolonized the sites. The sites were harvested using the following techniques: milling, block-cut and the upper and lower field techniques. Our research shows that peat mosses recolonize the restored sites quite fast as long as suitable environmental conditions, especially suitable hydrology, are found on the site. Additionally, the height of the water table, peat’s thickness, pH and conductivity, as well as the conductivity of water have significant effects on the growth of Sphagnum. However, the results show that, even after 30 years of restoration, only a small percentage of the crucial hummock forming species return to the sites. Mostly peat mosses growing in hollows (Section Cuspidata) established on the restored sites. As hummock-forming species are considered important for restoring the original biodiversity and peat-accumulating function, their return to peatland is crucial for a successful restoration. We believe that these species must be reintroduced for them to successfully establish on restored peatlands.},
