Invertebrate derived #eDNA (iDNA) is ready to move from the fringe of terrestrial ecological monitoring. Our new paper shows that it can be effective for large terrestrial mammals. Can’t wait to try out for other species @tecuk.bsky.social #conservation #bear onlinelibrary.wiley.com/doi/10.1002/...

Nearly 1 in 6 UK species are threatened with extinction. We've lost 97% of our wildflower meadows since the 1930s. We have 73 million fewer birds than in the 1970s - a decline of almost a third. And yet some politicians still just see wildlife as a blocker to progress.
