Paul joined Forest Research in 1997 as a student on an industrial placement year as a computer programmer. After completing his BSc in Software Engineering at De Montfort University in Leicester, he rejoined Forest Research in 1999.

Current role

Programming, modelling and QA for the forestry sector of the UK greenhouse gas inventory.

Paul is the FR project lead for the Emissions and Removals of Greenhouse Gases (GHGs) relating to Forestry Land in the UK National Greenhouse Gas Inventory. This work is funded by BEIS in collaboration with Defra, the Scottish Government, Welsh Government and the Department of the Environment in Northern Ireland. Since the 1990-2012 inventory Forest Research has supplied the estimates of the emissions and removals of GHGs relating to forest land for reporting under the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol.

This has involved using information from the GB national forest inventory, internal data on the public forest estate and national forestry planting and wood production statistics to design an algorithm to model the age, species, growth rate and management distribution of the forest area in each country. This is then used as input to the CARBINE carbon accounting model to give estimates of the carbon sequestered and emitted from forests land.

Paul also provides programming and technical support to the MOSES mixed species model, Forest Yield and the forecast system used in forest districts for managing the forest estate and centrally for producing National Forest Inventory forecast reports.
