Great crested newt surveys
- Habitat Suitability Index (HSI) assessments
- Presence/likely absence surveys and population size class assessments involving egg searches, torchlight searches, sweep netting and trapping
- Environmental DNA (eDNA) testing
- Monitoring surveys
- Identification of potential direct and indirect impacts, both at the site level and in a wider perspective: risks of disturbing, injuring or killing great crested newts, habitat modification, loss, fragmentation or isolation, post development interference impacts and poor data situations or ‘last minute discoveries’.
- Quantification of potential impacts in terms of extent, magnitude, duration, timing, frequency, reversibility and cumulative effects.
- Strategic advice on project feasibility.
Preparation of license applications to permit otherwise unlawful acts in relation to great crested newts.
- Precautionary working method statements, tool box talks, ecological clerk of works including destructive searches of terrestrial habitat and water-body draining and infilling, and receptor site selection.
- Habitat design plans including aquatic features, hibernacula and beneficial planting and landscaping schemes integration with hard landscapes
- Capture and exclusion using exclusion and drift fencing, pitfall trapping, netting, bottle trapping, draining down and hand searching ponds and night searching on land.
- Trapping and translocation of great crested newts
- Habitat management plans: management of aquatic vegetation in ponds, clearance of tree or scrub cover around pond margins, desilting and clearance of leaf-fall, mowing, cutting or grazing of grassland, woodland and scrub management.
