Save bogs to halt floods
In the US wetlands have been put back along the rivers for flood control. A river that can overflow on to areas of damp meadow, bog and wetland will cause less flooding in built-up areas downstream than one that cannot. A bog can hold rainfall before it ever gets to a river, lessening the pressure in very wet weather.
When wetlands were put back along US rivers, not only was flooding lessened downstream but the water quality improved and wildlife increased.
