Fire Behaviour Case Study : Mount Cook Station Fire, 16 January 2008
Veronica R. Clifford and H.Grant Pearce
This report describes the fire environment factors and fire behaviour during the Mount Cook Station fire in January 2008.Published Online - 09/2009. [1.8 MB] (pdf).This report describes the fire environment factors and fire behaviour during the Mount Cook Station fire in January 2008. It includes past weather conditions and details on the topography, fuels, weather conditions and fire danger experienced during the main runs of the fire. Fire behaviour reconstructed from observations is also compared with that predicted using current models for predicting fire behaviour in New Zealand fuels. -
Fire Behaviour as a Determinant of Fire Effects in Tussock Grasslands
H. Grant Pearce, Stuart A.J. Anderson and Ian J. Payton
This report describes the fire behaviour associated with experimental burns undertaken from 2000 to 2006 as part of the Tussock Fire Ecology project.Published Online - 03/2009. [1.1 MB] (pdf).This report describes the fire behaviour associated with experimental burns undertaken from 2000 to 2006 as part of the Tussock Fire Ecology project. This project aimed to examine the impacts of fire on tall-tussock grasslands to provide information on the consequences of burning on the native flora and fauna, and for the fertility and longer term sustainability of pastoral production. The study was a collaborative venture between Scion, Landcare Research, AgResearch and the Department of Conservation. Scion's role in the experiments was to quantify fire behaviour to provide estimates of fire intensity and burn severity for use in describing fire disturbance effects. A secondary objective was also to collect data to model fire behaviour in tussock fuels. Information was collected on vegetation biomass and fuel consumption, weather and fire danger conditions, moisture contents of soil and vegetation, rates of fire spread, fire intensity and flame size, and in-fire temperatures. -
Review of fire growth simulation models for application in New Zealand
H. Grant Pearce
New Zealand fire managers have expressed a desire for a spatial fire growth simulation tool to support operational and strategic fire management decision-making. This report reviews the suitability of available fire growth models for modification and use in New Zealand.Published Online - 02/2009. [860.5 KB] (pdf).Fire growth simulation models combine spatial data on fuel types and terrain influences, and temporal data on changing weather and fire danger conditions, with fire behaviour prediction models to simulate the spread and development of fires across the landscape. A wide array of fire growth simulators are available around the world that utilise a range of different modelling approaches and underlying fire behaviour prediction systems to simulate fire spread. New Zealand fire managers have expressed a desire for a spatial fire growth simulation tool to support operational and strategic fire management decision-making. As part of the proposed development of a New Zealand fire growth model, the objective of this report was to review the suitability of available fire growth models for modification and use in New Zealand. -
New Zealand Experimental and Wildfire Observer Guide
Todd Opperman
The purpose of this guide is to provide a field reference for researchers and rural fire observers to accurately document important aspects of rural fire behaviour. Standard forms are available.Published Online - 01/2006. [2.4 MB] (pdf).Well-documented fires can be used to evaluate suppression methods, validate burning restrictions, test fire behaviour models, and limit possible legal action against a fire protection agency. However, the data must be gathered accurately and uniformly among fire observers to have any value. The purpose of this guide is to provide a field reference for researchers and rural fire observers to accurately document important aspects of rural fire behaviour. Several aspects of fire observation are presented in this guide. Field navigation aids, mapping techniques and field instruments for weather observation are explained to help fire observers accurately record fires. Communicating and documenting fire observations can be facilitated by simple guidelines for communications and documentation using standard forms, which are outlined in this guide. -
Spatial Prediction of Wildfire Hazard across New Zealand - a significant upgrade
Craig Briggs, Robbie Price, and Grant Pearce
Upgraded digital maps describing fire behaviour potential across NZ were developed as part of the wildfire hazard input into the subsequent prediction of wildfire threat within the NZ Wildfire Threat Analysis System.Published Online - 09/2005.The objective of this project was to develop new high-resolution, 25m grid data layers to describe the wild fire hazard across New Zealand, utilising improved data sources like the Landcover Database 2 which was developed after the first iteration of this research in 2001.
