Dr Lorna Street is an ecosystem scientist; interested in how vegetation influences ecosystem carbon and nutrient cycling. She works mostly in Arctic and upland ecosystems. In the far north, climate warming is shifting the treeline northwards, and tundra vegetation is getting greener and more shrubby. A similar shift is happening in Scotland where woodland is re-established on treeless moorland.
Dr Street's work aims to understand how vegetation change influences carbon sequestration, particularly in the soil. Will a warmer, greener Arctic store more or less carbon? Will tree planting in the Scottish uplands offset our greenhouse gas emissions? She works on the fundamental science behind these questions.
