Burning Through Snow: A Guide to Winter Wildfire Prevention and Response


Winter Wildfire Prevention and Response


Wildfires pose a constant danger across North America. Their rapid spread can lead to severe property damage, and the aftermath can be equally devastating, with smoke, soot, and water causing further destruction. 

 

Wildfires have long been associated with the dry, hot months of summer, where the combination of heat, drought, and winds create a perfect storm for catastrophic blazes. However, in recent years, an unsettling trend has emerged. Winter wildfires are becoming more frequent and severe, posing a growing threat to ecosystems, communities, and firefighting efforts. Understanding the causes behind this shift and the implications it holds is essential for mitigating risk and ensuring preparedness. 

 


Winter Wildfire Prevention and Response



Factors Contributing to Winter Wildfires 


  • Climate Change: Historically, wildfire seasons in regions prone to fire would span from late spring through early autumn. However, climate change is altering these long-established patterns. Warmer winters are becoming more common, reducing snowpack levels, which act as a natural fire suppressant by keeping vegetation damp. Moreover, when winter precipitation falls as rain instead of snow, the ground dries out faster, leaving combustible materials exposed.

  • Human Activities: Careless human actions, such as improperly discarded cigarettes, campfires, or burning debris, can inadvertently start fires, even in winter. In addition, indiscreet development encroaches on forested and rural areas, increasing human presence in fire-prone regions. The expansion of power grids, roads, and residential areas means more potential sources of ignition, from malfunctioning electrical equipment to campfires and vehicles. 


  • Underground Fires: Fires can smolder underground, often unnoticed, for extended periods. During winter, underground fires pose a particular danger due to the presence of snow and the potential for hidden fuel loads. For example, lightning strikes, spontaneous combustion of organic matter, and volcanic activity can all ignite underground fires. Also, previous wildfires may leave behind smoldering embers that can reignite, especially in dry conditions. 


  • Dry Fuel Loads: The accumulation of dry vegetation, or fuel load, is another significant contributor to winter wildfires. During periods of drought or reduced precipitation, grasses, shrubs, and dead trees become tinder-dry, providing ample fuel for fires. Moreover, in winter, different types of vegetation become vulnerable. While deciduous trees lose their leaves and are less likely to contribute to fire spread, coniferous trees like pines retain their needles, which can become highly flammable under dry conditions. Invasive species, such as cheatgrass, which thrive in disturbed soils, can ignite easily and spread fires across large areas.

Prevention Strategies 

1. Vegetation Management 

Keeping vegetation under control is one of the most effective ways to reduce wildfire risk. During winter, property owners and managers must ensure that the grounds are properly maintained to limit potential fuel for a wildfire.

  • Clear Dead Vegetation: Remove dry grasses, dead leaves, branches, and any other flammable debris from around the property. Dead plant material, even under snow, can become fuel for a fire. 

  • Trim Trees and Shrubs: Maintain a clearance of at least 10 feet (3 meters) between tree branches and buildings. Trim back overhanging branches, and remove any dead or diseased trees, as these are particularly flammable. Ensure that trees and shrubs are spaced appropriately to prevent fire from traveling between them. 

  • Use Fire-Resistant Landscaping: Incorporate fire-resistant plants, gravel, or stone in landscaping near buildings. Vegetation resistant to fire burns less readily and can slow the spread of flames. 



2. Defensible Space 

Creating defensible space is critical in preventing the spread of wildfire to structures. 


  • Create Buffer Zones: Maintain a defensible space of at least 30 feet (approx. 10 meters) around buildings. This area should be kept clear of anything that can burn, such as dead vegetation, wood piles, or flammable structures like sheds or fences. 

  • Hardscaping: Use non-flammable materials such as gravel, stone, or concrete in areas directly adjacent to buildings. This not only limits the amount of vegetation that can catch fire but also acts as a firebreak. 



3. Building and Structure Maintenance 

Buildings themselves can be vulnerable to embers and flames during a wildfire. Proper maintenance can significantly reduce the risk of ignition.

  • Roof and Gutter Maintenance: Clean roofs and gutters regularly, as debris like leaves and pine needles can catch fire from windblown embers. Opt for fire-resistant roofing materials like metal or tile. 

  • Fire-Resistant Siding and Vents: Use non-combustible materials like stucco, brick, or fiber cement siding on exterior walls. Install ember-resistant vents to prevent embers from entering attics or crawl spaces. 

  • Check and Upgrade Windows: Single-pane windows can break in extreme heat, allowing fire to enter buildings. Consider upgrading to double-pane or tempered glass windows, which are more resistant to heat. 



4. Utility and Equipment Safety 

Utility equipment, especially during winter when winds can bring down power lines, is a common ignition source for wildfires.

  • Inspect Power Lines and Equipment: Make sure power lines near the property are well maintained and free of overhanging branches or vegetation. Coordinate with utility companies to ensure regular inspections and maintenance. 

  • Ensure Generators and Equipment are Fire-Safe: If the property uses backup generators or other machinery, ensure they are in good working condition and kept away from flammable materials. Store fuel safely, and ensure that equipment doesn’t spark near dry vegetation. 



5. Proactive Property Inspections 

Frequent inspections of the property grounds can help identify potential hazards before they become risks. 


  • Regular Walkthroughs: Schedule walkthroughs to inspect landscaping, gutters, roofing, and utility equipment. Look for signs of excessive debris or flammable materials that could ignite. 

  • Check for Vulnerabilities: During inspections, identify areas where embers could enter or where flammable materials are too close to buildings. Address these vulnerabilities by clearing debris or adding fire-resistant barriers. 



 

 

Preparedness: Building an Emergency Plan 

Despite taking all possible prevention measures, wildfires may still pose a threat. Property owners and managers need a comprehensive emergency preparedness plan to safeguard residents, staff, and buildings during a wildfire event. 


1. Develop a Property-Specific Wildfire Emergency Plan 

An emergency plan tailored to the specific needs of your property is essential for ensuring the safety of all occupants and protecting assets.

  • Evacuation Routes and Procedures: Clearly define evacuation routes and procedures for each building. Post these routes in common areas and provide copies to all residents and staff. Ensure that all routes are easily accessible and free of obstacles year-round, especially in winter when snow or ice may block paths. 

  • Designate an Emergency Assembly Point: Identify a safe location where residents and staff can gather during an evacuation. Ensure this area is outside of potential fire zones and accessible under various weather conditions. 

  • Resident Communication Plan: Establish a system to communicate with residents quickly and effectively during a wildfire event. This could include phone trees, mass text alerts, or email notifications. Make sure all residents are aware of how they will be notified in case of an emergency. 



2. Collaborate with Local Fire Departments 

Close coordination with local fire services is crucial in ensuring a swift response during a wildfire. 


  • Fire Department Access: Ensure that fire trucks and emergency vehicles can easily access the property, even during winter months when snow or ice may pose challenges. Keep gates unlocked or provide key access to emergency services. 

  • Water Sources: Maintain accessible water sources, such as hydrants or pools, which can be used by firefighters during a wildfire. Ensure these sources are functional and not frozen during winter. 

  • Emergency Drills: Partner with local fire departments to conduct emergency drills and educate residents on evacuation procedures. 



3. Stock Emergency Supplies 

Having essential supplies on hand can mitigate the impact of a wildfire on your property.

  • Fire-Extinguishing Tools: Equip the property with fire extinguishers, fire blankets, and hoses in easily accessible locations. Ensure staff and residents know how to use them. 

  • First Aid Kits: Stock first aid kits with essentials to treat burns, smoke inhalation, and other potential injuries. 

  • Backup Power and Lighting: In case of power outages, make sure the property has reliable backup power sources like generators. Have flashlights and batteries available for use in the event of an evacuation. 



4. Review Insurance Policies 

Ensure that the property is adequately insured against wildfire damage. 


  • Check Coverage: Review your insurance policies to confirm that they include coverage for wildfire-related damage, including rebuilding costs and loss of rental income. 

  • Document Property Assets: Keep an updated inventory of the property’s assets, including photos and descriptions of buildings, landscaping, and equipment. This will streamline the insurance claim process in the event of damage.
