From farmland to flourishing habitats

In 2015, Aldhurst Farm in Leiston was a 67-hectare arable field used to grow onions. Fast forward to today, and Aldhurst Farm is now Wild Aldhurst, a beautiful nature reserve combining grassland, heathland and wetland supporting a range of animals and plants.

We have now opened areas of Wild Aldhurst to the public to experience its rich biodiversity first-hand.

Restoring Suffolk’s lost landscape

Once stretching along Suffolk’s coast, the Sandlings landscape has mostly disappeared over the last 100 years.

At Sizewell C, we’ve been working to bring it back. In this video, our Ecology Lead, Dr Steve Mannings, shares how we’re restoring habitats and supporting local wildlife. This is more than conservation; it’s a new model for how major infrastructure projects can actively improve the natural environment.

Nature is thriving at Wild Aldhurst

Sizewell C’s environment team, together with our environmental partners, created Wild Aldhurst which, alongside other measures we are taking, will protect and enhance nature.

In the long run, our environmental measures will lead to a 19% net gain in biodiversity.

Marsh Harriers at Wild Aldhurst

Conservation efforts across the UK have seen marsh harrier numbers increase from near extinction levels to now over 500 breeding pairs. Some of these pairs have been spotted on our wetland habitat and as well as on Wild Aldhurst.
