Irish grasslands can roughly be divided into intensively used, frequently reseeded ‘improved’ grasslands and ‘semi-natural’ grasslands which are typically under extensive agricultural use but harbour greater biodiversity. Biodiversity is not only reflected in the number of species but also in the diversity of plant traits. This project addresses the important question of how plant diversity in semi-natural grasslands affects below-ground carbon storage and yield in response to climate-related stress. We will determine plant diversity (species and traits) in semi-natural grasslands in Ireland and conduct carbon audits to relate soil carbon profiles to plant diversity. Using high-resolution satellite and unmanned aerial vehicle (drone) imagery, we intend to classify grasslands and determine their biodiversity and yield through remote sensing. Our research will inform policy on the priorities for the management of semi-natural grassland habitats with the aim of protecting biodiversity while increasing carbon storage and yield stability in a future climate.
