After graduating in Ecological Sciences at Edinburgh University in 1977, Steve spent six years as a forest manager with the Forestry Commission in South Scotland. He joined Forest Research in 1983 to become the project leader for Conifer Breeding. Steve gained a PhD in the quantitative genetics of Sitka spruce in 1997, again from Edinburgh University. As well as experience of breeding conifers in Britain, Steve has spent time studying the breeding of loblolly pine in North Carolina and radiata pine in New Zealand. Steve has been involved in a number of consultancies around the world over the last 20-years.

Current role

Programme Group Manager for ‘Genetic Improvement’

Responsibilities cover all aspects of work relating to the breeding of conifer (Sitka spruce, Douglas Fir, Scots pine, Corsican pine, Larch) and broadleaf species (Birch, sycamore, ash, oak) in Britain. Overall, the work involves: selection of best origins for planting in Britain, consideration of emerging species in the light of climate change, planning experiments, co-ordinating data collection and analysis, estimation breeding values, composition of breeding populations, promotion and demonstration of genetic gain in the forest, and investigation of new DNA-based and tissue culture-based techniques which may speed up the rate of genetic gain getting to the forest. 

Conifer species:

  • Clonal Forestry
    Promoting the potential of Sitka spruce clonal forestry in Britain - demonstrating the superior gains from this means of deployment by analysing data from existing trails and establishing new field-based clonal trials.
  • Marker Aided Selection
    A new bio-tech. programme designed to identify superior Sitka spruce genotypes in the laboratory years before traditional field trials. Initial work involves planting the world’s largest Sitka spruce clonal test to ensure the best possible correlation between field performance and molecular markers in the lab.
  • Forward selection in full-sib progeny trails
    Bringing together Best Linear Unbiased Predictor (BLUP) -generated breeding values for a number of different traits into a single index value, which indicates an individual’s overall economic value.
  • Deployment of improved planting stock
    Promoting the best-available planting stock to the forest industry from seed orchards, family mixtures or use of new clonal-forestry technologies. Involves efficient management of pollination and grafting programmes and close liaison with scientist working on somatic embryogenesis and cryopreservation. Species involved are Sitka spruce, Scots pine, Hybrid Larch and Douglas Fir.
  • Wood quality studies
    In conjunction with colleagues in the Timber Quality team, investigating the genetic variation and economic value of various internal traits contributing towards the strength of Sitka spruce timber with the objective of increasing the proportion of timber satisfying higher construction grades.

Broadleaf species:

  • Future Trees Trust (FTT; previously known as BIHIP)
    Work closely with FTT to develop the breeding programmes for birch, sycamore, oak and ash.  Broadleaf breeding programmes are a lot less advanced and consist mainly of selecting good quality phenotypes then bringing grafted copies or seedlings from the phenotypes together so that they can inter-mate and produce improved seed for industry.
