On the Avon Wildlife Trust website, there's detail of the biodiversity initiatives being tried by the Thornbury Orchard Group. For example:
Oxeye daisy’s are a short lived perennial which establish quickly and are known as a pioneer plant. The species readily takes to bare ground and flowers from the second year onwards before other perennial wildflowers are able to establish and grow. Oxeye daisy’s need disturbed, open soil in order for the seeds to successfully establish, preferring well-drained soils in full sunlight. The site of the wildflower meadow is quite wet and includes other wildflowers and grasses.
The community orchard itself has been replanted since the 1990s, especially in 2022 when 70 trees and shrubs were introduced. It has a longer history:
...the orchard dates back over 200 years, evidenced with maps when the site was home to a Mill, powered by the Pickedmoor Lane stream. The site was owned by the local miller when Queen Victoria came to the throne. His mill pond was just over the road, where the stream still flows under and the mill, a little further down stream. Two old cider apple trees are still present from the earlier orchard.
There's mention of 'tree DNA' geneaology work, and a few of the apple varieties:
New trees planted include Gloucester Royal, Berkeley Pippin, Lemon Roy, Rhead's Reinetter, Arlingham Schoolboys and many more.
Across the Avon Wildlife Trust there's information including recommendations of plants for bees and pollinators.
