Ecological Survey
  • Phase I botany
  • Habitats of conservation value, and
  • Protected species of plants and animals:
      • White-clawed crayfish
      • Water voles
      • Otters
      • Bats
      • Badgers
      • Birds

5
Desk Study Results
  • Special Area for Conservation (SAC)


  • Site of Special Scientific Interest (SSSI)


  • Lower Wye SSSI designated as a salmonid fishery


  • EA highlighted rapids, adjacent and downstream habitats as suitable spawning areas for SAC fish species – although no specific records


  • Area supports a diverse assemblage of aquatic invertebrates


  • Other protected species records: great crested newt, several bat species, and hazel dormouse

Survey Results: protected species
  • Fish:
  • Habitat suitable for a variety
  • of species at different life stages.


  • Scoured areas
  • Clean gravels
  • Silt berms
  • Pools

Assessment
  • Most valuable features and habitats:
      • Substrate of the river bed for fish and
      •    invertebrates
      • Otter resting sites
      • Trees with potential to support roosting bats


  • Potential impacts:
      • Fish and invertebrates (including crayfish)
      • Otters
      • Bats
      • Dormice

Mitigation
      • Fish: Timing of works; protect and enhance habitat
      • Invertebrates: enhance habitat
      • Crayfish: rescue if present; enhance habitat
      • Otters: protect known resting site; temporary disruption
      • Bats: avoid impacts on occupied trees
      • Dormice: avoid impacts on occupied nests
