Lush, intertidal seagrass meadows appear to be spreading in SW England estuaries, replacing harmful, smothering green macroalgae. How can we evidence the changes (locally/globally) and how important are these new estuarine habitats?
With a multidisciplinary team from PML, University of Plymouth, JNCC and Westcountry Rivers Trust you will do research that covers everything from satellites to drones, benthic invertebrates to birds, and ecosystem services to socio-economic impact to identify the value of intertidal seagrass restoration.
What are the causes and ecological implications of the change?
Climate change may be a factor, but also changes in agricultural land management to reduce nutrient loads in upstream waters that drain into estuaries.
Subtidal seagrass has high conservation importance. We know it has positive impacts on biodiversity and provides ecosystem services including blue carbon storage and a nursery ground for fish and shellfish.
In contrast, the ecosystem services from intertidal seagrass are unknown!
This exciting and novel PhD project will:
This new knowledge will support and justify wider restoration and recovery of seagrasses.
You will receive training to take an interdisciplinary approach e.g.
Anecdotally there is an increasing occurrence of extremely lush summer growth of intertidal seagrass meadows in SW England estuaries (e.g. Tamar, Exe, TawTorridge) but with no formal evidence base. Intertidal seagrass is currently ignored in all ecosystem assessments, yet if it has the same potential ecosystem services as the much better understood subtidal seagrass, its recovery and growth may be an environmental good news story.
The project will train the student to take the interdisciplinary approach that is required for natural capital assessment to support management and policy development and implementation. The student will develop expertise in a suite of skills from earth observation image delivery and analysis via satellites and drones, to intertidal fieldwork, benthic ecology, biogeochemistry, through to conceptual thinking on ecosystem services and delivery of the natural capital approach. The student would be a good candidate for the EUMETSAT training courses, which teach all skills required for accessing and processing Sentinel-3 data, as well as boot-camp Python training. These skills are transferable to all EO sensors.
As a PhD student on this project you will receive appropriate training to take a multi and interdisciplinary approach:
The student project will be aligned with the NERC SWEEP project on natural capital in SW England, which seeks to create impact from NERC science.
The project will have wider implications for policy and management decisions as it considers implications of local land management and climate change for estuarine coastal ecosystems, recovery of seagrass – a species of high conservation and socio-ecological importance, and the application of the UK governments natural capital approach.
The supervisory team includes EO experts (Biermann), benthic ecology experts (Widdicombe, Austen, Attrill), seagrass expert (Attrill), ecosystem service and natural capital experts (Austen, Attrill), upstream land management and water catchment expert (Laurence Couldrick), conservation, restoration and policy expert (Maggs). All supervisors have extensive experience of working with local and national policy and management delivery bodies.
