The diagram in Fig. 1 shows a restored floodplain wetland beside a river in the Netherlands. A former straight flood bank has been set back, allowing water to enter shallow pools and reed beds during high flow. The site is used by frogs, dragonflies and wetland birds. Farmers nearby are concerned about flooding, while conservation groups support the scheme.

(a) Outline two ecological benefits of allowing the river to flood this wetland. [2]

Answer Details

(a) Any two: creates shallow-water and reed-bed habitats [1]; provides breeding sites for frogs/insects [1]; deposits nutrient-rich sediment that supports plant growth [1]; increases habitat diversity and therefore biodiversity [1]; stores water and can reduce downstream flood peak [1].
