  1. Directly plant non-woody plants: freshwater wetlands

    A replicated study in 2006–2007 along the shores of five freshwater lakes in Minnesota, USA (Vanderbosch & Galatowitsch 2011) reported 15% overall survival of planted softstem bulrush Schoenoplectus tabernaemontani plugs after approximately one year. The survival rate per lake ranged from 4% to 31%. It was significantly affected by month of planting and plug type, but not water depth. For example, plugs grown in pots and planted in June had the highest survival rate (39%) whilst plugs grown in pots and planted in August or grown in mats and planted in September had the lowest survival rate (3%). Methods: Between May and September 2006, a total of 3,750 bulrush plugs were planted along degraded shorelines within five urban lakes (150 plugs/month/lake, spaced 45 cm apart). Each greenhouse-reared plug contained 3–5 individual plants. Biomass at planting varied between months. Half of the plugs had been grown in pots and half on coconut fibre mats. Half were planted in shallow water (maximum depth 0–30 cm) and half in deep water (maximum depth 31–60 cm). All planted areas were fenced to exclude muskrats Ondatra zibethicus. Plugs containing ≥1 live plant were recorded until May–June 2007.
