Un-bee-lievable biodiversity at Limerick school 'deserves fifth Green Flag' Reporter: '); PUPILS and staff at Scoil Dean Cussen in Bruff have been busy bees preparing for their fifth Green Flag for biodiversity. Over the last two years, teachers and boys and girls have been making and taking surveys of the flora and fauna in the local environment, creating habitat maps and examining the meaning and importance of biodiversity in sustaining our environment. The Green Schools Committee, along with the teachers, created a plan to increase the level of biodiversity in the school grounds and raise awareness among the pupils and local community.
