Overview

Wildfires are a major agent of change on the planet and have been for millions of years. Wildfires are a natural component of many landscapes maintaining the health and vitality of ecosystems. However, large, dangerous wildfires, sometimes known as mega-fires, are becoming more frequent (e.g. e.g. Black Saturday Bush Fires, Australia 2009, burned 4500 km2; Fort McMurray, Canada, 2016, 5896 km2; Portuguese wildfires 2017, 5200 km2) and many can be found close to human habitation in the wildland-urban interface. This then poses a challenge for those working with wildfire – how do we balance the competing tensions between humans, ecosystems and natural processes.

In this module, we will explore the idea of pyrogeography as the comprehensive study of the physical and cultural parameters of fire. We will see how fire plays its role in maintaining ecosystems, how biotic and abiotic factors determine the nature and behaviour of fire, and how these aspects of fire ecology interact with human decisions in order to understand current fire management strategies.

 

Aims

  • introduce the ideas of pyrogeography (past, present and future distribution of wildfire) and fire ecology (fire effects on ecosystems, how ecosystems themselves influenced fire activity, and the role of fire as an ecosystem process).
  • investigate the different types of fire and their differing ecosystem effects.
  • consider the challenges associated with managing wildfires.
  • reflect on the debates around the use of prescribed fire as a management tool, both globally and in the UK.

Syllabus

The course comprises 10 weeks of 2-hour lecture sessions and associated seminars/practicals, with two study weeks, and broken into three sections:

i) Introduction: Fire behaviour

Section 1: Fire in the Earth System
ii) Geological history of fire
iii) Fire and climate

Section 2: Fire and the Biosphere
iv) Spatial and temporal patterns of fire
v) Plants, fauna and fire
vi) Fire as an ecosystem process

Section 3: Anthropogenic fire
vii) Fire behaviour and danger ratings
viii) Fire and land management
ix) Fire, the media and communication

x) Summary lecture
 

Teaching and learning methods

The course is delivered through a series of 2-hour lectures and 1-hour seminars/practical sessions. Students will be expected to complete assigned readings between lectures and undertake the support activities indicated for each class. A high level of attendance is expected and will help ensure that you possess basic knowledge on which to build for the course assessment. If you are not able to attend classes, please let the course leader know beforehand as it does make a difference to how we run some activities.

Across the module, a range of methods will be used including lecture-style sessions with student discussion and activities, seminars, practical sessions and discussion exercises. The sessions will be supported by online material, directed reading, and practical assignments, which will all be available via the Blackboard site. You will need to be prepared to engage with all material provided, as well as demonstrate wider reading around the course. Online teaching tools such as Blackboard Collaborate may also form part of the teaching and learning delivery.
