Surrey GU10 4LH

Jack Forster joined Forest Research as a research statistician in 2015, having previously worked as a statistician at the Home Office (2014-2015) and the Department of Energy and Climate Change (2012-2014). Jack received a 1st class Honours degree in Zoology from the University of Liverpool in 2008, and completed a PhD in theoretical ecology at Queen Mary University of London in 2012 , with specific focus on the response of growth rate and body size to increasing temperature in ectothermic organisms.

Current role


Providing a statistical consultancy service to researchers at Forest Research (both at Alice Holt and Northern Research Station) within three key areas:

  • Technical Skills - Providing up-to-date methodological expertise and analytical skills, using a range of innovative and modern statistical techniques and software
  • Quality Assurance - Actively encouraging the proportionate and consistent application of statistical quality assurance.
  • Knowledge exchange – Communicating and collaborating with Forest Research staff to provide statistical advice and to encourage the development of statistical literacy.

Current projects

Social and Economic Research
Recent work includes analysis of questionnaire data associated with the monitoring and evaluation of projects with Kew Gardens (Grow Wild) and the Active Forests Programme.

Land Use and Ecosystem Services Research
Use of structural equation modelling (SEM) to analyse woodland creation and ecological networks (WrEN) in collaboration with the University of Stirling.

Forest Management Research
Analysis of experimental data from a range of trials focussing on vegetation management and reducing herbicide inputs.

Climate Change Research
Recent work includes assessment of tree model reconstruction from Terrestrial Laser Scanner (TLS) readings.

Pests and diseases
Using mixed-effects models to assess potential multifactorial drivers of acute oak decline (AOD).

Other affiliations and responsibilities

Fellow of the Royal Statistical Society.
