Module DXX-2017:
Forest Health

Module Facts

Run by School of Natural Sciences

20 Credits or 10 ECTS Credits

Semester 1

Organiser: Dr Lars Markesteijn

Overall aims and purpose

This module aims to familiarise foresters and those concerned with forest ecosystems with the forest and tree health problems which have caused and are likely to have significant environmental, social and economic impact in the UK and the world’s forests, whether in commercial plantation or ‘natural’ forest ecosystems. The range of organisms covered will give a general overview of the organisms causing problems including viruses, bacteria, fungi, fungal like organisms, arthropods and mammals and parasitic plants. The module will follow a classical disease triangle approach whereby interacting factors of plant defence, organismal pathogenicity and environmental factors are considered. In case studies historical and current problems will be examined and their causes for wide scale spread and high levels of disease will be explored. The case studies will focus on a number of the newer exotic problems which have impacted on the UK's forest estate and will also examine the potential reasons for this and consider how these will be overcome and the longer term outcomes. Distinctions and comparisons will be made between the pathogens which have been in the UK forest ecosystems for millennia. The in depth focus of the module will concentrate on both fungal and insect issues and will examine future scenarios for forest health in line with climate change predictions. Some of the course content will focus on policy issues.

Course content

Forest Health, a definition Introduction to the problems in the forest: biotic, abiotic and interactions, particularly with climatic factors.
An examination of forest population dynamics and a comparison between managed plantation and natural forest ecosystems and its impact on forest heath Epidemiology: the kinetics of diseases. An introduction to new and emerging tree health issues within the UK and current concerns within forests and urban tree ecosystems Pests and pathogens of concern, and causes of problems The importance of plant and fungal genetics and quarantine Indigenous and long established problems, their impact and control Past failures in forestry and major international tree pathology events over the last 2 centuries.

Assessment Criteria

threshold

Grade D- to D+ Have a basic understanding of tree and forest health issues, show a basic knowledge of the conditions and organisms involved in different pest and disease severity

good

Grade C- to B+ As above but at a higher level of understanding and be able to demonstrate evidence of reading original papers rather than grey literature digests.

excellent

Grade A- and above As above but extensive level of knowledge and understanding and evidence of widespread use of both current and historical literature.

Learning outcomes

  1. Critical understanding of the organisms likely to cause economic losses to trees and their significance

  2. Critical understanding of the reasons for spread of, and success of, organisms causing economic losses

  3. Critical understanding of environmental factors which determine the development of pests and diseases

  4. Critical understanding of different management and control options for long term tree-crops and for more natural forest ecosystems

  5. General understanding of the likely effects of climate change on forest health
