Directly plant peatland trees/shrubs
A replicated before-and-after study in 2004–2008 three historically mined bogs in eastern Canada (Vander Kloet et al. 2012) reported that 63–100% of planted shrub clumps survived over four years, and that survivors had grown in diameter. Survival of bog cranberry Vaccinium oxycoccos was 100%, crowberry Empetrum spp. 83%, lingonberry Vaccinium vitis-ideae 71%, and mixed-species clumps (mostly Vaccinium berry species) 63%. Approximately 96% of surviving clumps showed positive growth (data not reported for single species). Amongst these, diameter increased by 50 cm/year for bog cranberry, 8 cm/year for crowberry, 22 cm/year for lingonberry and 7–8 cm/year for mixed clumps. Additionally, across all studied species, bigger clumps were more likely to survive (see original paper). In 2004, 916 clumps of shrub seedlings were planted, 1–2 m apart, along transects on wet peat. Initial clump diameter was recorded. Seedlings had been grown in a greenhouse from seeds in berries or scat fragments. In 2008, survival and final clump diameter were measured.
