Garden curator Marcus Chilton-Jones said: "Environmental responsibility sits squarely at the heart of everything we do, and in accordance with the trust's charitable objectives, we recognise our responsibility to protect and care for the environment we manage, as well as those beyond our boundaries.
"The garden acts as a haven for a huge variety of wildlife including birds, invertebrates, mammals, amphibians and reptiles, and our integrated garden management practices actively promote and encourage the symbiosis between plants and wildlife at all levels. We are constantly looking at ways to improve habitats for wildlife and have a continued commitment to educating all our visitors about our green credentials."
Visitors to the garden can enjoy the Edible Woodland, carefully designed with environmental sustainability in mind and the concept of "agro-forestry" at its core. The only publically accessible garden of its type in the Midlands, this style of garden is rare in the UK. It includes insect houses and an outdoor class room along with interpretation panels for visitors.
Beehives, a hibernacula for snakes (built with the help of local children) and a barberry hedge (Berberis vulgaris) are also found in the garden. The latter is part of a regional barberry moth conservation scheme, which aims to see these hedges planted in a continuous corridor from Cheshire down to Wolverhampton.
Winning the silver also gives the garden entry into the 2016 Visit England Awards for Excellence, to be held in March 2016.
