Ecological Mitigation for Quarry Restoration

Taylor Wimpey

Keystone Habitats were appointed by Taylor Wimpey to address protected species constraints prior to and during re-profiling work to restore the 72ha former Chinnor Cement Works in Oxfordshire.

What Did We Do?

  • Installed over 7km of heavy duty newt and reptile proof fencing
  • Created newt and reptile hibernacula
  • Cleared all tree and scrub vegetation in the re-profiling zone
  • Installed protective fencing around stands of Japanese Knotweed and commenced an eradication programme
  • Translocated orchids
  • Carried out destructive searches

How Did We Do It?

  • Regular programme meetings were held with Keystone Ecology, the client and their principal contractor
  • We made use of existing machinery on site for destructive searches
  • Vegetation clearance was largely timed to avoid the bird nesting season using a two phase cutting approach in areas with reptiles, completing clearance to ground level once reptile translocation was complete
  • We assigned a Habitats Contracts Manager who was licensed to handle Great Crested Newts to manage the project

What Were The Outcomes?

  • We devised a strategy that avoided the need for constant ecological supervision
  • Our approach saved the client costs associated with such supervision
  • We avoided programme delays
