2. Pinn Meadows Drainage Project

Aim: Improve wildlife corridors

Water body: River Pinn
Project description

To create a mosaic of ponds and scrapes in the wetland meadow

The Pinn Meadow is flooded for most part of the year, but standing water mostly congregate on footpaths and fields adjacent to resident's gardens. Even though these 'puddles' create a good condition for frog spawning, water evaporates before tadpoles have time to transform to adult frogs.

Instead of draining all water to the River Pinn, creation of mosaic of ponds and scrapes with different level of water would not only provide a water reservoir and alleviate flood problem, but it would provide a perfect condition for invertebrates, amphibians and wildfowl all year around.

Additional planting of wetland species such as: Marsh marigold, Ragged robbin, Meadowsweet, Yellow flag, etc. would increase biodiversity of the meadow. Those species could be found in other meadows downstream from Pinn meadows.
