Nadia joined Forest Research in 2004. She studied for an Ecology BSc. degree at King’s College London (1990-93). This was followed by a period of work as an Environmental Consultant in London. Between 1994-1998 Nadia worked towards her PhD degree in Floodplain Woodland Ecology at the Department of Geography, University of Cambridge.
Nadia continued to pursue her research interests in Riparian Ecology through Post-Doctoral Research (1999-2004) at the Centre d’Ecologie de Systèmes Aquatiques Continentaux (CESAC-CNRS), Toulouse, France and the Universities of Umeå and Mid-Sweden, Sweden. She also worked over this period for the French Ministry of Environment, producing for them a critical appraisal of 10+ years of French Ministry of Environment-funded Biodiversity research.
On joining Forest Research, Nadia was primarily engaged in developing and refining protocols for local and regional scale monitoring and assessment of environmental variables in forests. She lead the UK Long-term Intensive Forest Monitoring Network (an EU-wide forest monitoring platform) from 2004-2009. Since 2009 Nadia has been leading research in forest biodiversity
Biodiversity Project Manager and Ecohydrologist
Responsibility to provide the Forestry Commission and wider forestry sector with guidance on best forestry practice to protect and enhance woodland biodiversity and also effective means of monitoring, assessing, and reporting on forest biodiversity. Current specific areas of research and knowledge transfer relate to the biodiversity implications of a number of key forestry policy measures in Britain including (i) a drive for an increase in woodfuel production from existing woodland resources and short rotation forestry crops (e.g. eucalypts), (ii) the promotion of increased structural complexity in forest stands by creating a mixed age/compositional structure and (iii) the conversion of non-native to native woodlands.
There are active collaborations with Forest Research’s Ecosystem Services and Climate Change Adaptation Programmes covering the topics of forest regeneration, tree growth, provenance selection and indicators of forest ecosystem function.
