Senior Forest Ecologist – Biodiversity Monitoring & Assessment

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.

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

Management of multifunctional forests (MULTIFOR)

This four-year project involved a partnership of research organisations and local authorities from northern France and southern England, two regions with similar production and semi-natural forest ecosystems. Forest Research helped to develop common management strategies to maximise the economic, environmental and social benefits from forests in the two regions and to improve their resilience to climate change.

Factsheet: Climate change and biodiversity

More biodiverse woodlands are better able to resist or adapt to threats, such as climate change. This enhanced resilience supports the continuity of woodlands and the ecosystem services they provide. Biodiversity is the variation at different levels of biological organisation - the genes within a species; the species within a community; and the diversity between communities and ecosystems.

The natural capital of floodplains: management, protection and restoration to deliver greater benefits. Valuing Nature - Natural Capital Synthesis Report. VNP09.

Floodplains are important natural capital assets which deliver a wide range of benefits to people. The interface between terrestrial and freshwater ecosystems in floodplains fosters both a wealth and a complexity of resources that are challenging to measure and compare.

Encouraging biodiversity at multiple scales in support of resilient woodlands

Woodland ecosystems are integral to our health, well-being, security and economy, but they face a number of pressures including climate change, land-use intensification, and emerging pests and diseases. This Research Note explores the links between biodiversity, measured at different levels of organisation (genes, species and communities), and the ability of woodland ecosystems to withstand and […]

Using DNA barcoding and metabarcoding to detect species and improve forest biodiversity monitoring

Growing threats to biodiversity from pressure of land use, climate change, and invasive pests and diseases highlight the importance of obtaining accurate baseline measurements of current forest biodiversity, as well as improved monitoring to detect early signals of change. Developments in molecular techniques have advanced to the stage that there are now practical methods available […]

Converting planted non-native conifer to native woodlands: a review of the benefts, drawbacks and experience in Britain

Planted forests of non-native conifers make up around 36% of Britain’s total wooded area. Increasing the area of native woodlands – including converting non-native conifer to native woodland where appropriate – is an aim of the UK Forestry Standard Guidelines on Biodiversity. It is unclear how much conversion is being implemented, what the motivations might […]
