Westonbirt Arboretum has many different habitats and is a rich location for bio-diversity. We work with volunteers, conservation groups and individuals to address our bio-diversity goals.
The open grassland of the Downs landscape covers the area of Westonbirt between the Old Arboretum and Silk Wood. The area is rich in wildlife and wildflowers and work is underway to restore this Grade I registered landscape and encourage the many diverse habitats that can and do live there.
Ancient semi-natural woodland
Silk Wood is ancient semi-natural woodland and contains Britain’s native trees (around 40 species).
Differing habitats can also be found within the ancient semi-natural woodland areas such as Silk Wood, which are home to rare wildflowers and elusive species such as the male Bechstein's bat.
There are 15 hectares of actively worked coppice: work which involves many volunteers and professional coppice workers in the up keep of historical woodland.
The worked areas of hazel coppice in Silk Wood are particularly rich in native wildflowers and wildlife. The long term coppice restoration project will help further develop this aspect.
