Development of improved methods for detection, control and eradication of pine wood nematodes in support of EU Plant Health Policy (REPHRAME)
Extending the capability of existing models to identify the risk posed by pine wood nematodes to the rest of Europe and the possible impact of climate change on its spread
- Development of fundamental models of stem volume Developing improved single tree volume estimation models for both coniferous and broadleaved tree species. The new models are specifically designed to provide more reliable estimates, particularly for larger trees that might be expected under alternative silvicultural management regimes.
- Modelling Pine Wilt Disease Working with partners in Germany and Portugal to model the risk of expression of pine wilt disease (PWD) under projected climatic scenarios.
- Testing of soil carbon model predictive performance Testing a recently-developed, improved sub-model of soil carbon dynamics (intended for incorporation into the FR CSORT and CARBINE models), by meta-analysis of model predictions against published estimates of soil carbon stocks and CO2 fluxes.
