Paul is the project lead for the development of methods for the modelling of GHG balances of trees and woodlands, particularly for application in the estimation of national GHG emissions inventories for forested land, as reported by the UK under the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol. He has developed algorithms for combining a range of data sources on UK forests, including:

  • National Forest Inventory (NFI) data
  • Forestry records maintained by the public forest and land management agencies
  • Historical records of tree planting and woodland loss (deforestation)
  • Statistics on timber and wood production from forests.

This information is used as input to the CARBINE forest sector carbon accounting model, to produce national- and regional-scale estimates of GHG emissions and carbon sequestration associated with afforestation, deforestation, forest growth and forest management. Paul took over as the main developer of the CARBINE model in 2010.

Paul also provides programming and technical support to the improvement of FR’s main forest growth models, including:

  • Forest Yield – software based yield tables for forest management in Britain, which was published in 2016
  • The M1 growth model, used in many FC and FR systems, including the FC Forecast System and the CARBINE carbon accounting model
  • MOSES GB, which is a key next generation model being developed by the FC project, Modelling Mixed-Age and Mixed-Species Stands.

Paul joined Forest Research in 1999, having first worked there for a year as a student in 1997/98 as part of his degree in Software Engineering at De Montfort University in Leicester.

Paul draws upon his deep knowledge of computing and software engineering in his research into the modelling of forestry systems. He is one of the main original developers of the FC Forecast System, used by forest and land management agencies to plan day to day forest management, and by the Forestry Commission for producing National Forest Inventory (NFI) Forecast Reports. Paul also applies these skills in his research into improving the modelling and forecasting of forest greenhouse gas (GHG) balances, particularly at national and regional scales.
