It is expected that climate change will impact UK river ecosystems (Hannah & Garner, 2015) as a consequence of extreme low-flows and high river water temperature events (Garner et al., 2017a). The survival and growth of salmonid fish are influenced strongly by river temperatures raising concern that the thermal suitability of rivers could be reduced (Malcolm et al., 2008). As a result, river managers in Scotland have implemented bankside tree planting as a technique to help river ecosystems adapt to climate change by providing increased shading, especially in summer (Garner et al., 2017b). Recent research by the University of Birmingham (UoB) and Marine Scotland Science (MSS) has led to the development of statistical models capable of identifying areas where rivers are hottest and most sensitive to the impacts of climate change (Jackson et al., 2018). However, these models are unable currently to identify precise locations where bankside tree planting will have the greatest benefits in terms of river temperature. Consequently, there remains an urgent need to inform river and land managers about optimal tree planting to promote further resilience of Scottish rivers and fisheries to climate change. The findings of this project will allow CASE partner MSS to inform national policy development while also providing applied management tools for use by fisheries boards and trusts.
In this context, this CENTA2 PhD project aims to use process-based river temperature models to determine how near-stream tree cover, landscape and other environmental factors interact to control river water temperature. These models, which function by simulating the physical processes that drive stream temperature, will shed new light on the locations in which bankside tree planting will have the greatest impact on moderating stream high temperature extremes during summer. The model outputs will be integrated with existing large-scale river temperature monitoring initiatives coordinated by MSS with partners, helping to identify optimal locations for tree planting across Scotland as a climate change adaptation strategy.
CASE partner Marine Scotland Science (MSS) provides expert scientific advice on aquatic environments to the Scottish Government, supporting its policy-making and regulatory activities. This collaboration represents a unique PhD training opportunity and will ensure research findings are put directly into practice. The key project deliverable (‘planting opportunity’ GIS metric) will be immediately used by MSS to support river management efforts. The collaboration between UoB and MSS will ensure that the research represents the ideal balance of scientific rigour and real-world utility, enhancing process-based knowledge of river temperatures while delivering a timely and desirable river management product. Without access to MSS’ river temperature data and modelling expertise, model implementation and testing would be challenging in a realistic field setting. The student’s training experience will be of much greater substance than a similar non-secondment PhD and the experience gained from working in an applied research environment will mean that their employment prospects will be greatly enhanced.
