New eDNA test for great crested newts


IMAG3928Natural England are now accepting the new eDNA test as evidence of presence/absence of great crested newts for licence applications. This test requires a single visit to the pond (rather than the traditional 4 visits) to take a water sample which is then tested.

However, the water can only be sampled at a certain time of year and if newts are present, the traditional 6 presence/absence surveys will still be required. Therefore, eDNA will be useful for schemes with a low/temporary impact, or developments with a long lead-in time.
