are undertaking ground-breaking environmental DNA surveys in south London green spaces. Image: NHM Scientists working with the Natural History Museum (NHM) are calling for volunteers to help with a remarkable new survey coming to green spaces in Croydon and Bromley. The Big Bug Hunt is taking place Tuesday, June 8-Wednesday June 9 and hopes to survey insect populations at the Hutchinson s Bank and Chapel Bank nature reserve on the southern fringes of Croydon and Bromley. To do that the scientists involved are hoping to recruit some budding volunteers who will gain fascinating insights into the scientific process and help further our knowledge about insect populations, animal DNA and how we can best preserve south London green spaces like Hutchinson s Bank.
