Talk Outline • Outline of Fire Management in Ontario • History of Fire Detection • Current Detection operations • Detection Results • Challenges
Ontario’s Fire Management Program Forests cover 85% of Ontario’s land area and forest fires have shaped much of this environment. Land cover composed primarily of Boreal and Mixedwood Forests. Ontario averages roughly 1,300 fires annually. $94 million spent annually to protect communities and natural resources. $4.1 billion in Gross Provincial Income annually attributed to forest fire protection.
Policy Fire Management Strategies 6 Fire Management Zones • Southern Ontario • Parks • Great Lakes/St. Lawrence • Boreal • Northern Boreal • Hudson Bay • Ecoregion-based planning rather than zones based on geographically or politically based
Policy Fire Management Strategy • Emphasizes the need to balance fire response and fire use • Performance targets are aligned to policy objectives • Balancing fire response against risk and ecological benefits. • New performance measures have been developed: • Forest Depletion Area Burned • Hazard Reduction Area Burned • Ecosystem Renewal Area Burned • A flexible response to fires through the concept of Managed Fire.
Performance • The key performance measure is Initial Attack Success • Target is 96% IA Success
Annual Number of Fires 10 year average - 1,283
10 year average – 152,188 Annual Hectares Burned
Organization • District Office • Response Centre • Two Regional Fires Centers direct day-to day operations • A Provincial Fire Centre oversees two Fire Region Centres • 29 Attack bases • 225 Permanent staff and 760 seasonal positions
Detection in Ontario • At the turn of the century Ontario began to build towers • Most towers were erected between 1920 and 1950 • At the peak there were 320 active towers • During the late 1960’s and early 1970’s most towers were decommissioned – replaced with Aerial detection
Current Fire Detection Program • Aerial - Fleet of 15 Contract Aircraft • Public - Common reporting system • Reports direct to Fire Centres
Detection Planning • Aerial Detection advantage is flexibility • Detection planning is based on risk, expected fire starts, and expected fire behavior
Detection Costs • Basing fees = $675,000 for 15 contract aircraft • Positioning Fees = $225,000 • Flying costs = $325 to $635 /hour/aircraft. Average 270 hours per aircraft for approximate flying costs $2,000,000 • Spend around $3.0 million annually on organized detection
Results • Or: • What did we buy with that $3,000,000? • Or: • Some Embarrassing Statistics

Challenges • Performance measures • Investment level • Integration of new technology
Performance Measures • Audit Results • Working towards A robust performance measure • Recognize Detection as Part of a larger system
Detection Performance • Goal of Forest Fire Detection: Deliver Fires to Suppression Organization at a state that guarantees a high probability of IA success at a minimum cost. Draft Goal
Detection Performance • Goal of Organized Forest Fire Detection: Deliver Fires to Suppression Organization at a state that guarantees a high probability of IA success without competing with other detection sources Draft Goal
Different Suppression Weights Conceptual Detection Target 96% likely successful Initial Attack Expected Fire Behavior Detection Size
Detection Performance Complicating Factors • Cost Trade Offs • Suppression weight vs additional detection • Build in “Random Detection” into system • do not want to compete
Summary • Ontario’s Fire Management Strategy allows for Managed Fire • Fire load and area burned is highly variable • Ontario uses a fleet of contract aircraft for fire detection • Most fires are detected by “random” sources • Working towards a robust performance measure
