  1. Directly plant trees/shrubs: freshwater wetlands

    A study in 1979 of a swamp restoration project in Florida, USA (Gilbert et al. 1980) reported that 7–85% of planted tree seedlings survived over 4–5 months. Of the 16 planted species, survival was lowest for longleaf pine Pinus palustris (7%) and highest for green ash Fraxinus pennsylvanica and baldcypress Taxodium distichum (both 85%). For all species, the survival rate varied between plots at different elevations. Statistical significance was not assessed. Methods: In January and February 1979, seedlings of native Florida tree species were planted into a wetland undergoing restoration. The site was historically a swamp, then mined for phosphate. It was modified before planting by levelling spoil piles, creating wet basins and installing inflow/outfall pipes. Most of the 10,400 seedlings were planted in 26 multispecies plots (4–5 species/plot; seedlings 1.5 metres apart) but some were planted randomly throughout the site. Survival of planted seedlings was recorded in June 1979.
