Ash dieback: notice of site closure 6-17 January 2025

Sadly, ash trees at the Nature Discovery Centre have been affected by ash dieback, a serious disease that weakens trees and increases the risk of them falling or losing branches. To ensure the safety of our visitors and protect the surrounding area, we need to carry out essential tree felling work this winter.

To carry out this essential work, the Nature Discovery Centre, including the car park, paths and playground, will be closed from Monday 6 January to Friday 17 January. We’ve scheduled the work during winter to minimise disruption to birds and other wildlife.

We understand this will change the appearance of the site, but we’re committed to restoring it. Plans are already underway to plant new trees with the help of the local community, ensuring the area remains a haven for nature and visitors.

For further information about the work, please contact the Nature Discovery Centre on ndc@bbowt.org.uk or 01635 874381.

The Nature Discovery Centre is surrounded by a mosaic of different habitats with fantastic wildlife to see all year round. Wander along the paths beside the lake, visit the internationally important Thatcham Reedbeds nature reserve or explore some of the nearby woodland. There is a large network of footpaths, perfect for family days out or the more adventurous.

Birds

During the autumn and winter, large groups of wintering wildfowl congregate on the lake, whilst the reedbeds and surrounding woodland and hedgerows host birds like fieldfare and redwing.

In spring and summer, purpose-built rafts attract breeding common terns. House martins, swallows and swifts are a common sight over the lake and surroundings.

Throughout the year, one of our volunteers surveys the species of bird found on site. The bird lists below show the variety of species that visit across the seasons.

Our volunteer also leads regular walks around the reserve to help visitors learn about what they can see and hear during their visit and learn more about each species.

Plants

In summer there are glorious displays of purple loosestrife, yellow-flag iris, reeds and sedges on the floating island, the lake shore and in the reedbeds.

All year around look out for the willow and alder around the edge of the lake, and hawthorn, blackthorn, spindle and bullace in the hedgerows.

Invertebrates

A variety of moths and butterflies can be seen, including garden tiger, butterbur, waved black, holly blue, and gatekeeper. There are dragonflies and damselflies including beautiful and banded demoiselles, emperor and four-spotted chaser. A range of beetles such as bloody-nosed beetle and rhinoceros beetle have been recorded on site.
