Making wetlands more resilient to climate change

Norfolk Rivers Trust have been overseeing work on the wetlands between the Strawberry Field and the river. The aim is to make the wetlands more resilient to climate change. Recent extended droughts have resulted in some of the wetland peat drying out, with release of carbon dioxide, and an adverse effect on flora and fauna. Pools are being created to store more water in time of flood, the water then being available during dry periods.

In the foreground is a stilling pool. This is deep enough to reduce the velocity or turbulence of the water flowing into the pool system and encourage sedimentation prior to the water entering the main pool. The channel leads to the main water storage pool.

The channel enters the storage pool on the left. The other end of the storage pool is sloping to encourage a variety of flora and fauna habitat.

Nearby a scrape has also been created. Scrapes are shallow ponds of less than 1m depth with gently sloping sides. They hold rain or flood water seasonally and, hopefully, will remain damp for most of the year.

It all looks rather stark at the moment, but it will not be long before nature takes advantage of the opportunities offered, and all will assume a softer natural appearance.

The changes will be monitored by the Norfolk Rivers Trust to see how effective they are in reducing the drying out of the wetland. The Trust has further projects in hand to improve the effectiveness of the Yare Valley as a wildlife corridor.
