Extending sampling approaches for great crested newt (Triturus cristatus) eDNA monitoring

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Environmental DNA (eDNA) monitoring has been used for great crested newt (Triturus cristatus) survey in the UK since the publication of a Defra‐funded trial in 2014 and approval of a regulated protocol. Our study provides evidence that changes to this protocol, including use of filtration for eDNA capture and permitting eDNA surveys in July and August,
