Mathematical Modelling Tools for Conservation and Disease Management

As well as being important in human and agricultural populations, it is increasingly recognised that infectious disease has important impacts in natural systems. In particular it is now clear that infectious disease can be important in conservation and may affect the ability of foreign organisms to invade natural communities. Ecological theory has been important in showing the general importance of disease in natural systems, but has only been rarely used to direct conservation programs. The project investigators have a track record in translating established research on disease-mediated ecological invasion into mathematical tools that can be used to direct conservation management decisions and policy. This project will answer current, pressing questions outlined by conservation agencies on the red-grey-squirrelpox system in Scotland. The objectives in the project have been specified by the project partners (Scottish Natural Heritage, Scottish Wildlife Trust) who need to know the potential impact of squirrelpox on remaining red squirrel populations, whether grey squirrel control can prevent squirrelpox spread and the critical locations and effort at which control is required. This information is essential to allow our conservation partners to formulate current and future management plans that allocates limited resources in a manner that maximises red squirrel protection. The modelling framework, which predicts temporal and spatial disease dynamics on large-scale, complex landscapes, is the best tool available to underpin these conservation efforts. Therefore, this NERC Innovations proposal provides a unique opportunity to translate established research into effective conservation strategies that provide direct tangible benefits to end-users.
