Tarmac and Natural England commissioned EMEC Ecology to carry out the independent survey of saproxylic Coleoptera – beetles which rely on dead or decaying wood – at its Panshanger Park site as part of efforts to enhance the site’s potential for wildlife further.
Two of the species identified have never before been recorded in the county, one of which is a rare beetle of ancient woodland, while the other has only been identified at four other locations in the British Isles.
The survey was completed as part of the Parkland Management Plan, produced in partnership with Natural England, Historic England, and Herts and Middlesex Wildlife Trust to identify how the historic grade II* listed landscape of the park could be further enhanced in the future for both nature and visitors.
Tarmac has owned the Panshanger Park land since the 1980s and, from the 1990s, carried out phased mineral extraction of sand and gravel in the park, with much of the material being used to build homes and roads throughout Hertfordshire. Quarrying has ended, with large park areas being opened and managed for public enjoyment and conservation.
Tarmac is working with local stakeholders and partners to implement the new management plan, which will include planting new parkland trees and increasing the area of wood pasture. Low-intensity grazing will be expanded to enable natural processes to develop a more structurally diverse woodland and tree population and a richer mosaic of habitats.
Michael Charlton, mineral estates manager at Tarmac, said: “As stewards of this site, we have taken on a huge responsibility to care for this ancient woodland, which is home to so many rare species and one of the most important places for wildlife in Hertfordshire.
“This survey is helping us to form our management plans for future years, which will involve carefully managing our veteran trees to ensure these beetles will continue to have a home at Panshanger Park for centuries to come. The abundance of wildlife at Panshanger demonstrates the ability to responsibly quarry and restore an area to create an asset that brings a variety of benefits to flora, fauna and the wider public.”
Sarah Clarkson, team leader at Natural England, said: “Panshanger is really exciting because it is such a good example of how nature can co-exist with people and still thrive, so we have a double win. It’s so important that people from all backgrounds and communities can access green space and gain from the benefits to health and wellbeing that connecting with nature brings.”
Tim Hill, conservation manager with Herts and Middlesex Wildlife Trust, said: “Having been working with Tarmac to restore and manage Panshanger Park’s historic landscape for the last 18 years, I am delighted that the value of conserving the vast amounts of rotting wood at the park has been revealed through this excellent study. What is almost as exciting is that we can all provide a home for saproxylic beetles by including some big lumps of rotting wood in our gardens. In doing so, we have the chance of encountering awesome creatures like the Lesser Stag Beetle – dead wood is dead good!”
Adrian Dutton, entomologist at EMEC Ecology, said: “Panshanger Park is a truly exceptional location thanks to the continuity of decaying wood that has been present for hundreds of years. It is because of this that diverse populations of saproxylic beetles have been able to thrive here, marking it as one of the most important locations in the UK, and potentially Europe.”
The survey contributes to a number of ecological surveys that have been carried out at Panshanger Park. Over 12,000 species have been recorded alongside healthy populations of water voles, bat and 19 species of dragonfly.
Tarmac has also recently planted a new 17,000-tree woodland on former agricultural land at the park as part of the Queens Green Canopy initiative.
Panshanger Park is open to the public daily from 8am-6pm; further information is available at panshangerpark.tarmac.com
