Event details

Free event for on Fri 31 May & Sat 1 Jun

This spring, we are inviting you to join in the biggest ever survey of England’s forest wildlife. The Big Forest Find will take place at Westonbirt, and in other forests across the country, as expert ecologists lead volunteers on a journey of discovery through England’s wooded landscapes.

From birds and butterflies to insects and plant life on the forest floor, the information recorded will help to paint a better picture of England’s forest biodiversity today.

To carry out the work, we are working with wildlife and conservation organisations and will host expert-led walks around the arboretum on Friday 31 May & Saturday 1 June.

The Big Forest Find builds on the success of Westonbirt’s 2017 BioBlitz, which saw over 800 different species of flora and fauna being recorded across two days. This information helps us manage the valuable ecosystem provided by the Arboretum. This year, we are delighted to be working with Butterfly Conservation, Back from the Brink, Gloucestershire Raptor Monitoring Group, iNaturalist, Forest Research, Gloucestershire bat group, Bristol Naturalist Society and Gloucester Naturalist Society.

The Big Forest Find is part of the Year of Green Action, a year-long drive in 2019 to help people to connect with, protect and enhance nature.
