Project proposal presentation

  1. 1. REGENERATION AND EARLY GROWTH MODELS FOR MOSES_GB Project proposal for a PhD in Forestry Simone Bianchi SENRGY Website:
  2. 2. Contents 1.Why do we need a forest regeneration model? 2.What is the modelling framework? 3. How the work will be carried out?
  3. 3. 1.Why do we need a regeneration model? Photo © Mat Disney, NERC CTCD, 2005, from UK forestry dominated by artificial plantation of coniferous species, managed with clearfell. The resulting forests are very organized ecosystems, which behaviour is relatively easy to predict. Edwards, P.N., & Christie, J.M. (1982).Yield Models for Forest Management. Forestry Commission Booklet, 48.
  4. 4. 1.Why do we need a regeneration model? source: The future: continuous cover silviculture of complex mixed-species, uneven-aged forests ! Focus on natural processes!
  5. 5. 2.What is the modelling framework? MOSES-GB MOSES (Austria)
  6. 6. 2.What is the modelling framework? 1. Occurrence and density 2. Early growth 3. Mortality And a regeneration component: MOSES_GB IS AN INDIVIDUAL TREE MODEL: There is an overstorey component…
  7. 7. 3. How the work will be carried out? Research questions: How can the (1) probability of regeneration occurrence and density in coniferous stands and (2) the early growth of Sitka spruce seedlings be modelled? (3)Which are the significant factors to be included in those models, in order to easily integrate them in MOSES-GB?
  8. 8. 3. How the work will be carried out? YEAR ONE 1. Literature review on (i) forest regeneration modelling and (ii) coniferous species regeneration in the UK (completed) 2. Retrieval of existing dataset from Forestry Commission (under way) 3. Field survey in Clocaenog Forest,Wales, to collect preliminary observations and test methodologies (under way) 4.Investigating what can be done with the existing data, identify the missing gaps, define the modelling framework we want to follow (under way)
  9. 9. 3. How the work will be carried out? Stand characteristics Site characteristics Regeneration characteristics Light regime • Lack of existing data on regeneration in the UK1 versus the high requirement for empirical approaches • Regeneration occurrence/density is a highly random process 1 Kerr,G., Stokes,V., Peace,A., &Wylder, B. (2011). Prediction of conifer natural regeneration in a “ data-poor ” environment. Scottish Forestry, 65(3), 28–36.
  10. 10. 3. How the work will be carried out? YEARTWO 6. Extend the field surveys to other region in the UK and/or to different forest types (other coniferous species or even broadleaves) 7. Model calibration and validation YEARTHREE 8. Wrap up
  11. 11. If a tree grows in the forest, does it make any sound? Acknowledgements: • Dr Christine Cahalan, Bangor University &Tom Jenkins, Forest ResearchAgency • Forestry Commission and Forest Research Agency • Scottish ForestryTrust The end.Thanks! Any questions?
