Spotting seasonal species at Exeter Cathedral The countdown to the first Exeter Cathedral BioBlitz has begun. The 'BioBlitz' is a fun activity with an important mission. The aim is to identify as many species around the Cathedral grounds and green spaces as possible over two days; creating the chance to explore and hopefully discover something unknown and unusual. Working with Devon Wildlife Trust and the landscape architect, we will use our findings to increase the biodiversity around us, contributing to the increase and preservation of our wildlife.
