In Northern Ireland, Pilgrim's Europe kickstarted a biodiversity project by planting 350 trees on the grounds of its facility in Ballymena. Pilgrim's Europe team members planted the trees in April 2022 with the help of eager students from Slemish College and Straid Nurseries, who provided the trees and equipment. Pilgrim's Europe has been working with the school, Mid and East Antrim Borough Council, and the Woodland Trust to enhance biodiversity around the Pilgrim's Europe site, maintain a more diverse ecosystem in the local area, and offset carbon emissions.
Future activities planned as part of the biodiversity project at Ballymena include establishing habitats for pollinators, growing wildflower meadows, and installing bird boxes around the area.
