Silviculturist in the Forest Management Research Group

Victoria leads and manages silvicultural research in Upland Forestry. She carries out research on alternative management systems, emerging species, silviculture of broadleaved species, and alternative establishment techniques.

She also manages Forest Research’s Long-term Experiments project, a network of around 320 experiments covering topics including mixtures, species, provenance, nutrition, ground preparation, stability and exposure, timber quality, spacing, thinning, native woodlands and natural regeneration. The project aims to conserve the best field experiments as a strategic resource that can be re-examined to address current and future questions about sustainable forest management.

Victoria is a member of both the Institute of Chartered Foresters and the British Ecological Society.

Dr Victoria Stokes joined Forest Research in 2002, after completing a PhD at the University of Essex which involved research into the carbon and water balance of mature oak and sycamore tree canopies. She initially worked as an environmental physiologist on short rotation forestry, and now carries out research on many aspects of upland silviculture.

An analysis of conifer experiments in Britain to identify productive alternatives to Sitka spruce

An analysis of relevant species trials was carried out to assess the productivity of potential alternative conifer species to Sitka spruce on upland site types in Britain. Data from 87 forest experiments planted between 1929 and 1995 were analysed to compare long-term performance of 52 species with that of Sitka spruce under the same conditions and site type.

Intimate mixtures of Scots pine and Sitka spruce do not increase resilience to spring drought

Understanding how we can increase the resilience of forest systems to future extreme drought events is increasingly important as these events become more frequent and intense. Diversifying production forests using intimate mixtures of trees with complementary functional traits is considered as one promising silvicultural approach that may increase drought resilience. However, the direction and magnitude […]

No seed zone effects on the survival, growth, and stem form of Pacific silver fir in Britain

Long-term research finds Pacific silver fir has great potential as a forestry species in Britain With our climate changing and an increasing range of pests and diseases affecting trees in Britain, it is important forest managers diversify the tree species they plant and use a wider range of forest management systems (e.g. continuous cover forestry). Pacific silver […]

Controlling rhododendron through the use of herbicides

Problems associated with Rhododendron ponticum. Rhododendron ponticum is a highly invasive species affecting woodland in the UK. It is also a host to two particularly significant diseases affecting our woodlands – Phytophthora ramorum and Phytophthora kernoviae. To control their spread, the eradication of rhododendron, usually by cutting and removal, is an accepted management practice. The […]
