Habitat suitability surveys for Great Crested Newt can be undertaken throughout the year, but are more effective in the summer months when an accurate assessment of vegetation cover can be undertaken.
Presence / absence can be determined by undertaking four ‘standard’ surveys, which involves searching for Great Crested Newt within ponds using torches, nets, bottle-traps and egg searches. If presence is determined, then a further two ‘standard’ surveys are required to establish the population size. Surveys should be carried out between mid-March and mid-June, with half of the surveys undertaken between mid-April and mid-May.
Alternatively, presence / absence can be determined by testing water samples from ponds for Great Crested Newt DNA (eDNA surveys), which can be carried out between mid-April to June. If presence is determined, an additional six ‘standard’ surveys are required to assess the population size.
