  1. Excavate pools (without planting)

    A replicated, before-and-after, site comparison study in 1999–2005 in seven bogs in Quebec, Canada (Fontaine et al. 2007) reported that created pools developed a different plant community to natural pools, but with similar species richness. After six years, the overall composition of the plant community differed between created and natural pools (data reported as a turnover index and graphical analysis). In particular, cattail Typha latifolia was more frequent in created pools (occurring in 69% of quadrats) than natural pools (0% of quadrats). Sphagnum mosses, Eriophorum cottongrasses and Carex sedges were sometimes more abundant in restored pools and sometimes less abundant, depending on the species (see original paper). Created and natural pools both contained 24 plant species/0.5 m2. In 1999, four 6 x 12 m pools were created in a historically mined bog by excavating and rewetting (blocking drainage ditches and building embankments). In 2005, cover of every plant species was estimated in 0.5 m2 quadrats situated on pool margins: 12 quadrats around the created pools and 30 around pools in each of six natural, unmined bogs. This study was based on the same experimental set-up as (1).
