Directly plant peatland mosses Peatland Conservation

A before-and-after study in 1989–1992 in a fen in the Netherlands (Kooijman et al. 1994) reported that transplanted shoots of scorpion moss Scorpidium scorpioides grew in length and spread to new parts of the fen. No statistical tests were carried out. Twenty months after transplant, “many” shoots had died but remaining shoots had grown 3 cm on average. New plants were found in 25 grid cells up to 1.2 m from original transplants. After three years, this had increased to plants in 80 grid cells up to 2 m from the transplants. In November 1989, five rings of live scorpion moss (3.5 cm diameter) were cut from an Irish fen and planted in the Dutch fen, where scorpion moss was absent. Five plants in each ring were marked 3 cm below the shoot tip. In July 1991, measurements were taken of shoot length (above the marks) and expansion of moss plants into grid of 10 x 10 cm squares around the transplants. Expansion measurements were repeated in December 1992.
