Summary
Action: Excavate pools/ponds
A replicated study in 1993 of seven excavated pools near Utrecht, the Netherlands (Beltman & Allegrini 1997) reported that they were colonized by aquatic macrophytes within four months, and that the abundance of individual species changed over time. The pools contained 6–12 aquatic macrophyte species. The most abundant species in the younger pools (4–6 months old) were fragile stonewort Chara globularis and bristly stonewort Chara major. The most abundant species in older pools (22–23 months old) were common stonewort Chara vulgaris, Nuttall’s waterweed Elodea nuttallii and broad-leaved pondweed Potamogeton natans. Data were reported as abundance classes. Methods: In September 1993, aquatic macrophyte species and cover were recorded in seven pools (in 4 m2 quadrats along transects). The pools had been excavated in a wooded fen 4–23 months previously. They were 1 m deep, 30–40 m wide and 100–700 m long. Some contained remnants of aquatic vegetation after excavation; others were completely bare.
