This species poses a significant threat to the Critically Endangered native northern pool frog through disease transmission, competition, and hybridisation. Ickburgh is some 12km from the known native pool frog population at Thompson Common. The northern pool frog became extinct in the UK by the 1990s but has been successfully reintroduced through a collaborative project led by Amphibian and Reptile Conservation and Natural England. Reintroductions began in Norfolk in 2005, with a second release at Thompson Common from 2015-2021. Protecting these populations is critical to securing the future of this rare amphibian. A national contingency plan is in place to respond to an incursion of invasive non-native animal in England. Natural England is the lead agency responsible for the management response. The proposed activity will use eDNA sampling to determine the extent of marsh frog presence/absence across selected water bodies, starting near native pool frog habitats and moving east to west to minimise disease risk. Outputs will include a spatial distribution map to inform Natural England and partners on management control options. ## CPV classification Laboratory services Research laboratory services Source Find a Tender (UK) · Notice ocds-h6vhtk-068582-2026-06-11T14:43:52+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-068582-2026-06-11T14:43:52+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
