Hydrock on behalf of Wales and West Utilities
Keystone Ecology were contracted to carry out Ecological Due Diligence Surveys in respect of ground investigation works at a Glenfrome Gas Works, Bristol.
What did we do?
- We carried out an Extended Phase I Habitat Survey and desk study to enable the determination of ecological impacts, guide selection of mitigation options and identify requirements for further ecological survey if required.
- Produced a Precautionary Working Method Statement (PWMS) to:
Prevent the killing and injury of Great Crested Newts and reptiles;
Minimise habitat loss that could potentially be used by Great Crested Newts and reptiles, in the case of the former, to ensure habitat loss remains within the parameters for a PWMS to be acceptable;
Avoid destroying/disturbing Badger setts.
How did we do it?
- Liaised closely with Hydrock contract managers to devise site investigation working methods that could progress under a PWMS and thereby avoid the need for further survey/consultation with regulators in respect of Bristol Wildlife Networks Site, Broadleaved Woodland, Great Crested Newts, reptiles, Badger, nesting birds and Japanese Knotweed.
- Carried out vegetation clearance under the PWMS using Keystone Habitats, our in-house ecological contracting team who are trained in precautionary working methods for protected species.
What were the outcomes?
- A potential delay in the start of investigation work due to the potential presence of various protected species was eliminated.
- The need to employ an Ecological Clerk of Works in addition to a vegetation clearance contractor was avoided and resulted in overall project cost savings.
