Joan Cottrell joined Forest Research in 1991, where she established the molecular laboratory and is responsible for introducing molecular marker technology.

Current role

Programme Group Manager

Responsibility for the management of the molecular laboratory that uses polymerase chain reaction (PCR) based techniques to assess genetic diversity, genetic structure and gene flow in natural tree populations of species such as oak, black poplar and wild cherry.

The genetic conservation group has been involved in several large EU funded projects such as FAIROAK, EUROPOP and OAKFLOW which aim to assess the genetic diversity in tree species on a European scale.

In addition, the laboratory is collaborating with staff in the Centre for Forest Resources and Management to use molecular markers to search for quantitative trait loci in Sitka spruce. We also collaborate with Tree Health staff in the Centre for Climate Change and have contributed to work on Horse Chestnut Bleeding Canker and Pine tree lappet moth.

Current programmes and projects

  • Genetic conservation
    Improving our understanding of the genetic resources present in British tree populations. This includes:
    • Research into the genetic diversity and geneflow in British populations of oak, black poplar, ash, rowan, cherry and Scots pine
    • Maintenance and measurement of provenance trials of rowan and ash from populations sampled across Britain
    • Collaborating with landscape ecologists to examine the effect of various features of the landscape matrix on genetic connectivity using wood crickets as a model species
    • Developing molecular tests to identify the species of origin of faecal samples for fox, pine marten, capercaillie, black grouse and various species of bat; these have been used by field ecologists to confirm presence of these species.
  • Using molecular technology to characterise the biology of Pseudomonas syringae pv. aesculi, the bacterium which which causes bleeding canker of horse chestnut
    Includes applying molecular techniques to try to discover the origin of a population of Pine tree lappet moth which was discivered a few years ago in Scotland.
  • Selection and testing of conifers
    Marker aided selection in Sitka spruce - managing the molecular contribution to this programme.

Affiliations and achievements

  • 2004 Silvicultural Prize awarded by the Institute of Chartered Foresters for best paper in the journal ‘Forestry’.
  • British representative for EUFORGEN poplar network
  • Member of the UK Plant Genetic Resources Group
  • PhD supervision of students from for Edinburgh and Southampton Universities and external examiner for PhD theses from Bangor and Southampton University.
