What Property Owners Need to Know Right Now
Wildfire activity across Canada and the western United States has surged dramatically this July, with over 500 active fires recorded nationwide and more than 200 burning out of control. Saskatchewan, Manitoba, and parts of the Northwest Territories are facing some of the highest fire loads in recent history — triggering new evacuation orders, highway closures, and air quality alerts. Alberta remains under watch, with localized flare-ups and smoke drift affecting air quality in several regions.
For both homeowners in wildland-urban interface (WUI) zones and commercial property owners near forested or grassland regions, this isn’t just another bad season. It’s a critical time to re-evaluate your wildfire defense strategy.
Key Wildfire Stats (as of July 20, 2025)
National Wildfire Database: 561 active wildfires across Canada, with 69 currently classified as out of control.
Saskatchewan & Manitoba: These are now the most heavily impacted provinces, with multiple out-of-control fires and recent evacuation orders affecting northern communities.
Northwest Territories: Aggressive fire growth near Jean Marie River and Fort Smith continues to drive emergency response efforts.
Evacuation Orders: In effect across parts of Saskatchewan, Manitoba, and the Northwest Territories.
Air Quality: Dense smoke has caused intermittent air quality alerts across the Prairies, including Saskatoon and southern Manitoba. Calgary and Edmonton are currently in moderate-risk zones.
Track Wildfires in Real-Time (Natural Resources Canada)
What’s Driving This Surge?
Meteorologists attribute the current surge in wildfire activity to a combination of prolonged drought, record-breaking heatwaves, and dry lightning events, particularly across the Prairies and the North.
While British Columbia has seen some lightning-caused fires earlier this season, it is not currently a hotspot. The majority of July’s new fire starts have been concentrated in Saskatchewan, Manitoba, and the Northwest Territories, many of them lightning-ignited in dry boreal zones.
Alberta's fire danger remains moderate, with localized areas showing high risk — but it is not under extreme province-wide threat as it was in spring.
What This Means for Property Owners
For Homeowners:
WUI properties are at increased risk from ember attacks — flying embers that ignite roofs, decks, and dry vegetation.
Most structure loss during wildfires begins with embers entering attic vents, eaves, and vegetation within 10m of the home.
Home defense kits (with fire-rated hose, sprinkler kits, and water supply pumps) are now considered essential in rural zones.
Shop Ember Protection Here
For Commercial Property Owners:
Industrial parks, warehouses, and agricultural facilities adjacent to brush or tree lines must assess:
Ventilation intake vulnerabilities
Combustible material storage
Staff training for emergency response
Many commercial claims are denied due to lack of active fire suppression systems or non-compliance with NFPA wildfire readiness guidelines.
NFPA Wildfire Preparedness for Businesses
Immediate Actions You Can Take
Clear Your 0–10 Meter Zone: Remove brush, mulch, and woodpiles. Clean gutters and cut grass. This is the critical ignition zone.
Check Your Fire Equipment: Test pumps, hoses, extinguishers, and backup generators. Ensure everything is operable and accessible.
Review Your Insurance Coverage: Confirm that your policy covers wildfire-related damage, including smoke and heat exposure.
Install Ember Protection: Mesh screens over attic vents, fire-resistant roof materials, and perimeter sprinklers make a measurable difference.
What to Expect Next
July 25–Aug 10: Saskatchewan, Manitoba, and the Northwest Territories are forecast to remain under high to extreme fire risk due to continued heat and dry conditions. While parts of Alberta may experience above-average temperatures, British Columbia is not projected for record-breaking heat, and fire activity is expected to remain stable.
NWT Outlook: Satellite monitoring indicates continued fire growth potential near Fort Smith, Jean Marie River, and the South Slave Region, driven by wind and dry fuel beds.
Smoke Plumes: Air quality across Manitoba, Saskatchewan, and parts of Ontario is expected to fluctuate through late July due to heavy wildfire smoke. Calgary and Edmonton are currently in the moderate range but could see temporary smoke drift depending on wind direction.

What Does a Foot Valve Do?
Foot valves are one-way check valves attached to the intake (“foot”) of a pump’s suction line. They allow water to flow up to the pump but prevent it from flowing backward when the pump stops or pauses, thus keeping the suction hose and pump primed. Most foot valves include an integrated strainer to filter out debris, ensuring the pump doesn’t ingest sticks, sand, or muck from the water source. Flash Wildfire Services offers a range of foot valves and related components suitable for homeowners drawing from ponds, totes, wells, or gravity-fed tanks.
Below are key products – including foot valves, portable pumps, hoses, and connectors – along with their descriptions, product links, compatibility notes, and other useful details for choosing and using them.
Foot Valves & Strainers
1-1/2" Brass Spring Loaded Foot Valve – A brass foot valve with a spring-loaded check mechanism to prevent backflow during suction. By keeping water from draining out of the hose, it maintains the pump’s prime and makes priming easier. This 1.5″ valve threads onto standard 1½″ suction lines (often using NPSH or NPT threads). It is an affordable, durable choice for small jet pumps or transfer pumps drawing from wells, barrels, or shallow ponds. View Here
2" F.NPSH Footvalve Strainer – A heavy-duty 2″ female NPSH threaded foot valve with an integrated screen strainer. This unit is designed to “prevent debris intake, ensure max flow & protect pumps” in wildfire defense, irrigation, or industrial pumping. The stout strainer basket keeps out leaves, fish, and large debris while the internal check valve maintains suction. It attaches to any 2″ NPSH suction hose (a common thread on portable fire pumps) and is suitable for high-flow home applications (e.g. drafting from a pond for irrigation or sprinkler systems). View Here
B-5258 Foot Valve and Strainer 2" – A premium 2″ NPSH combination foot valve (aluminum body) with a built-in strainer, made for high-pressure pump systems. Its spring-loaded check valve is capable of holding a water column up to 300 PSI in head pressure – meaning it seals tightly to keep heavy suction lifts primed. An “ear” loop on the valve allows it to be tethered to a float, keeping it off the pond bottom to prevent sucking up sediment. This model is specifically made for WATERAX portable pumps like the MARK-3®, BB-4®, Striker II-PLUS, UltraStriker, or any pump with a 2″ (51 mm) NPSH intake*. In other words, if you have a high-performance fire pump, this foot valve is the matching heavy-duty intake filter to use. View Here
Foot Valve and Strainer 1-1/2" NPSH (Aluminum) – A similar combination foot valve strainer in the 1.5″ size. It features an aluminum housing with a stainless-steel screen and spring-loaded internal valve (very much like the 2″ B-5258 above, but scaled down) . This unit is ideal for smaller centrifugal pumps that are not self-priming – the foot valve will “keep your pump primed, ensuring smooth, uninterrupted water flow” . It has 1½″ NPSH female threads to connect to 1.5″ suction hose, and can be used on portable pumps or even gravity-fed pipeline intakes where a one-way intake valve is needed. View Here
3" Foot Valves and Large Strainers – For high-flow needs - 3″ Red Cast Iron Foot Valve, a rugged cast valve for large-volume water transfer (listed at a budget-friendly price around $49). There are also barrel strainers with foot valves in 2½″ and 3″ sizes for firefighting or irrigation pumps – for instance, a 3″ NPSH Barrel Strainer w/ Foot Valve (heavy-duty metal strainer, $649) if you have a high-capacity pump or a cistern/gravity feed with a 3″ line, these products provide the necessary intake protection. View Here
Portable Fire Pumps (Compatibility & Usage)
Several portable pumps carried by Flash Wildfire Services are compatible with the above foot valves. For homeowners in wildfire-prone or rural areas, these pumps can draft from static water sources (ponds, tanks, pools) – and a foot valve will usually be used on the suction hose for best results. Key examples:
WATERAX MARK-3® High-Pressure Pump – The MARK-3 is a legendary wildland fire pump (4-stage centrifugal, 10 hp two-stroke engine) known for high pressure output. Flash Wildfire offers the modern Mark-3 Watson Edition as well as the classic variant. These pumps have a 2″ NPSH suction inlet and require priming before use – typically accomplished with a pump primer and a foot valve on the suction line to hold prime. The B-5258 2″ foot valve above is “specifically made for use on the MARK-3, BB-4,” and similar pumps. Homeowners who invest in a MARK-3 (or its slightly smaller cousin the BB-4®) for wildfire defense or high-head water transfer will want a robust 2″ foot valve strainer to go with it.
WATERAX VERSAX® 2-Stage Pump – The Versax series is a versatile, rugged, and economical twin-impeller pump line ideal for general water supply tasks. For example, the VS2-6W Versax uses a 6 HP Honda engine and produces up to 120 PSI and 105 GPM, making it useful for “firefighting, tank filling, high-head water transfer, boom spraying, [and] irrigation”. The Versax pumps are self-priming (they have a built-in priming design), but using a foot valve on the 2″ suction hose is still recommended for drawing from ponds or wells – it helps the pump keep its prime between runs and blocks debris. In a home setting, a Versax pump paired with a 2″ foot valve strainer and a good suction hose can serve for wildfire sprinkler systems or irrigating a acreage from a creek.
Floating Pumps and Other Options – Flash Wildfire also sells specialized pumps like the PFP-6HP-FL Floating Pump (a lightweight pump that actually floats on the water’s surface). A floating pump comes with its own screened intake, so a separate foot valve isn’t needed in that case. However, for most trailer-mounted, skid-mounted, or portable ground pumps, you will select an appropriate foot valve as described above. Smaller hand pumps or backpack pumps generally use built-in check valves for priming (e.g., the Guzzler hand primer has internal check valves, but even its documentation notes that adding a foot valve can significantly increase suction lift capacity). Always match the foot valve size and thread type to your pump’s suction inlet size and thread standard (NPSH vs. NH vs. NPT) – the product listings and compatibility notes can guide you in choosing the right one.
Suction Hoses & Connectors
To actually use a foot valve with your pump, you’ll need a proper suction hose and possibly some adapters. Flash Wildfire Services offers a variety of hoses suited for home-scale pump setups:
Suction Hose Assemblies: You can get pre-made suction hose lines such as a 2″ x 10′ clear PVC suction hose with male and female NPSH threaded ends. This is a typical rigid (or semi-rigid) hose that connects from your pump intake to the foot valve in the water. PVC suction hoses are lightweight and adequate for moderate use. For heavier-duty or frequent use, rubber suction hoses are available (e.g. a 2″ x 10′ black rubber suction hose, 150 PSI rated, with NPSH couplings) – these withstand more abuse and remain flexible in colder temperatures. Hoses on the site come in common lengths (10 ft, 15 ft, etc.) and diameters (1.5″, 2″, 2.5″, 3″) to match the foot valves and pump sizes discussed.
Adapters & Fittings: Ensuring all components can connect may require adapters, especially if different thread standards or quick-connect systems are involved. Flash Wildfire Services stocks many hose fittings to bridge these gaps. For example, if you need to attach a 2″ NPSH female hose to a 1.5″ NH (National Hose aka “forestry”) male fitting, they have a Reducer Adapter – 2″ NPSH Female × 1.5″ Forestry Male in aluminum. Likewise, adapters exist to go from NPSH threads to camlock fittings (quick-release couplers) or to standard pipe threads (NPT), etc. There are also double-female or double-male adapters to join hoses, and swivel couplings that allow easy rotation when threading on a foot valve. When setting up a home pump system, you might use a 2″ double-female NPSH coupling to connect a male-ended foot valve to a male pump inlet, or a 2″ NPT to 2″ NPSH adapter if your pump has pipe threads. All these can be found in the “Adapters & Fittings” section of the shop. The goal is to achieve a secure, leak-free line from the water source (through the foot valve and hose) to your pump.
Using the right combination of foot valve + strainer, suction hose, and connectors will significantly improve the reliability of your pumping system. The foot valve keeps the pump primed and prevents the frustration of losing prime (and having to re-prime) every time you stop the pump. The strainer on it guards the pump impeller from damage by debris. And the hoses and fittings complete the path so you can draw water from wherever it’s available (pond, cistern, rain barrel, etc.) with confidence. All the products described above are actively sold on FlashWildfireServices.ca, making it a convenient one-stop source for homeowners preparing pumps for emergency wildfire protection or everyday water transfer needs.
When it comes to wildfire defense, the hose you choose matters. Each hose type has unique features, pressure ratings, and durability profiles designed for different levels of wildfire exposure, terrain, and use cases. This guide breaks down what makes Type 1, Type 2, and Type 3 hoses different—and how to choose the right one.
What Are Type 1, Type 2, and Type 3 Hoses?

Wildfires are fast, unpredictable, and unforgiving. For homeowners in high-risk zones, preparation means more than just clearing brush and hoping for the best—it means having the right equipment on hand to support early suppression efforts, assist professionals when possible, and stay safe while awaiting emergency response.
Unfortunately, many well-intentioned homeowners make critical mistakes when selecting wildfire protection gear. These errors can lead to wasted money, false confidence, and most importantly, missed opportunities to slow down fire spread, reduce structure vulnerability, or protect personal safety during a wildfire event. This guide outlines the most common mistakes homeowners make when choosing wildfire equipment—and how to avoid them with smarter, safer, and more strategic planning.
1. Mistaking Garden Gear for Fire Equipment
The Problem:
Many homeowners believe their existing garden hoses and sprinklers are sufficient for wildfire protection. Unfortunately, most standard hoses, fittings, and nozzles are not built to withstand high temperatures or prolonged use under emergency conditions.
Why It Matters:
In a wildfire, heat, embers, and pressure demand more than everyday garden tools. Equipment failures during a critical moment can lead to greater property damage, or worse, increase the danger to those on-site. Even short-term tool failures can reduce the effectiveness of structure hardening.
What to Use Instead:
Fire-rated hoses: Made from rubber or nitrile blends, capable of withstanding high heat and pressure.
Aluminum or brass nozzles: Durable and heat-resistant.
Steel hose reels or rapid-deploy bags: Organize and extend hose lines quickly.
Pro Tip: Some garden hoses fail at temperatures as low as 130°F, which is well below the radiant heat from nearby vegetation fires.
2. Choosing the Wrong Size or Type of Pump
The Problem:
Fire pumps are essential for drawing water from tanks, ponds, or pools, but not all pumps are designed for wildfire response. Homeowners frequently purchase low-pressure utility models that can’t support long hose runs or uphill lifts.
Why It Matters:
Having a pump that fails to prime, can’t push water at adequate PSI, or is incompatible with your hose fittings can render your entire setup useless. In wildfire events, property access is often limited—relying on reliable, correctly matched equipment is critical.
What to Look For:
Pumps with 100+ PSI pressure output
Vertical suction lift to draw from remote water sources
Fire-grade hose outlets (often 1.5") with compatible fittings
Pro Tip: Ensure pump maintenance supplies (extra gaskets, spark plugs, intake strainers) are stored nearby, and test your system regularly.
3. Buying Tools Without a Deployment Strategy
The Problem:
Wildfire response often comes down to seconds and accessibility. Homeowners may collect quality tools—but store them in garages, sheds, or locations difficult to reach quickly under stress or smoke.
Why It Matters:
Even if you're not using tools to fight fire directly, having access to rakes, shovels, and other equipment can help in real-time mitigation: clearing flammable debris, opening pathways, or handing gear to trained responders.
Strategic Tips:
Stage tools in exterior lockers: Avoid smoke-filled structures.
Group tools logically: Pulaski, shovel, rake, gloves, mask, and eye protection together.
Create labeled deployment zones: Tools should be available at key areas like driveways, fence lines, and near outbuildings.
Pro Tip: Some departments recommend homeowners use tools to assist with ember cleanup after fire has passed. Organized tools allow this to happen safely.
4. Overlooking Personal Protection Equipment (PPE)
The Problem:
While Flash Wildfire Services does not promote homeowner fire suppression, we do recognize that there are moments—such as evacuation delays or structure prep—when being on-site is unavoidable. In these situations, having basic protective gear is a crucial safety layer.
Why It Matters:
Wildfires often create unpredictable conditions: thick smoke, airborne embers, and falling debris. PPE won't make a homeowner into a firefighter, but it can help reduce injury risk while preparing your home, evacuating, or assisting others.
Recommended PPE for Evacuation-Readiness:
N95 or P100 respirator mask: Protects lungs from fine smoke particles
Sealed safety goggles: Shields eyes from ash and airborne debris
Sturdy gloves: Protect hands when moving gear or clearing access points
Long-sleeve, non-synthetic clothing: Minimizes skin exposure and reduces burn risk
Battery-powered headlamp: Essential for low-visibility conditions during power outages or night movement
Pro Tip: PPE should be stored in wildfire go-bags placed near exit points and access roads. It's not about staying to fight—it's about staying protected until it's safe to leave.
5. Failing to Plan for Power Outages
The Problem:
When wildfires knock out power, electric gates, garage doors, well pumps, and hose reels can all become non-operational. This not only reduces your access to equipment, but can also limit mobility or evacuation.
Why It Matters:
Preparedness means assuming systems will fail. Manual access to water, gear, and evacuation routes is non-negotiable.
Resilient Setup Suggestions:
Use gravity-fed tanks with manual hose systems
Install manual overrides for electric gates and garage doors
Keep battery-powered lighting and backup power packs with each gear bundle
Pro Tip: Practice accessing your wildfire equipment without electricity or lighting at least once a year. This exposes vulnerabilities and trains household members.
Final Thoughts: Preparation Isn't About Taking Risks—It's About Reducing Them
Flash Wildfire Services does not encourage homeowners to fight fires. But we do encourage proactive preparation using the right equipment, tools, and layout strategies.
Our role is to help property owners:
Prepare their sites safely
Equip themselves for real-time decision-making
Support suppression efforts when appropriate
Stay protected in remote, high-risk environments
Mistakes in gear selection aren’t just about wasted money—they represent missed opportunities to protect your home and safety. Choosing smart, compatible, field-ready wildfire equipment is one of the most important steps a homeowner can take in building true resilience.
Wildfires are complex and dangerous events, with temperatures that vary significantly and pose a range of threats to life, property, and the environment. Understanding the science behind wildfire temperatures is crucial for comprehending fire behavior, predicting its effects, and developing effective mitigation strategies. This article provides a deeply researched, fact-based exploration of wildfire temperatures, their measurement, influencing factors, and impacts.
I. The Temperature Range of Wildfires
Wildfire temperatures are not static; they fluctuate and vary within a fire. It's essential to differentiate between average temperatures and the extremes that can be reached.
Surface Fires: These fires, which consume low-lying vegetation like grasses, shrubs, and leaf litter, typically reach temperatures of 800°C (1472°F) or higher. Flame heights are often around 1 meter.
Crown Fires: Fires that burn through the canopies of trees can reach temperatures exceeding 1000°C (1832°F) or even 1200°C (2192°F) under extreme conditions. Flame heights can reach 50 meters or more.
Variations Within a Fire: Temperatures within a wildfire are not uniform. The hottest areas are usually within the active flame front, while areas behind the front may be cooler.
Flash Point vs. Fire Temperature: The flash point of wood (the temperature at which it ignites) is around 300°C (572°F). However, wildfires achieve significantly higher temperatures to sustain combustion and spread.
II. Methods of Temperature Measurement in Wildfires
Directly measuring wildfire temperatures is challenging due to extreme conditions. Scientists employ various techniques:
Infrared Thermography: Infrared cameras and sensors measure thermal radiation emitted by a fire, allowing for temperature mapping across the fire.
Remote Sensing: Satellites and aircraft with thermal sensors monitor fire temperatures over large areas.
Hyperspectral Imaging: Instruments like AVIRIS analyze spectral emissions to estimate fire temperatures and identify burning materials.

As wildfires continue to pose a significant threat to communities across North America, the creation of defensible space around homes has become an indispensable safety measure. While various strategies contribute to wildfire preparedness, the selection and maintenance of landscaping plants often represent an overlooked yet remarkably effective tool in mitigating the risk of fire spreading to residential structures. By carefully choosing plant species that exhibit inherent fire-resistant characteristics, homeowners can substantially decrease the likelihood of their property becoming vulnerable during a wildfire event.
However, the effectiveness of fire-resistant plants is not uniform across all geographic regions. Environmental factors such as climate, average rainfall, and soil composition play a crucial role in determining which plant species will thrive and provide optimal fire protection. What flourishes in the dry, arid conditions of the Western United States may not necessarily survive or offer the same level of resistance in the more humid environment of the Southeast. This comprehensive guide aims to address this variability by providing a detailed breakdown of the most suitable fire-resistant landscaping plants categorized by region, alongside practical advice on how to effectively integrate them into a fire-wise landscape design.
Why Fire-Resistant Plants Are Critical
Fire-resistant plants are defined as those species that possess characteristics making them less prone to ignition and slower to spread flames. These plants typically exhibit several key traits that contribute to their ability to withstand or slow down the progress of fire. A high moisture content within the plant tissues is a primary factor, as the water acts as a natural barrier to combustion. Conversely, plants with low amounts of resin, sap, or volatile oils are less likely to ignite readily and burn intensely. Growth habits also play a role; slow-growing or compact plants tend to have less dry biomass that can act as fuel. Furthermore, leaves that are thick, fleshy, or succulent often retain more moisture, making them less flammable. Finally, fire-resistant plants generally exhibit minimal retention of litter and dead wood, reducing the amount of readily available fuel for a fire.
Utilizing these types of plants in the landscape surrounding a home creates a crucial buffer zone. This zone can effectively slow down the intensity of an approaching wildfire, giving firefighters or any installed wildfire defense systems a greater opportunity to protect the property. It is important to understand that while the term "fire-resistant" suggests a high degree of protection, it does not imply that these plants are entirely "fireproof." Under extreme conditions, virtually any plant material will burn. The term "firesafe" is often used to describe plants that, under normal circumstances, are less likely to become a significant source of fuel for a fire. Beyond the immediate benefit of fire protection, incorporating fire-resistant plants can also aid in the recovery of the landscape following a fire, helping to reduce topsoil loss and erosion caused by subsequent rainfall.
Best Fire-Resistant Plants by Region
The selection of appropriate fire-resistant plants is heavily dependent on the specific environmental conditions of a given region. The following section provides recommendations tailored to different areas of North America.

General Landscaping Tips for Wildfire Defense
Regardless of the specific region, several universal fire-wise landscaping practices can significantly enhance a home's protection against wildfires.
1. Create Defensible Zones: Establish three distinct zones around the home. Zone 1 (0–5 feet) should consist solely of non-combustible materials like gravel, hardscape, and irrigation systems. This area, sometimes referred to as Zone 1A, should have a very low potential for ignition from flying embers. Deciduous trees are preferred for shade in this zone over evergreens due to their higher moisture content. Zone 2 (5–30 feet) should feature low-growing, widely spaced, fire-resistant plants. Zone 3 (30–100+ feet) can transition to native vegetation, which should be thinned and regularly maintained.
2. Prune and Maintain Regularly: Trim tree branches to a height of 6–10 feet from the ground. Remove any accumulation of dead wood, dry leaves, and pine needles from roofs and gutters. Consistent removal of dead plant material and thinning of dense vegetation are essential maintenance tasks. Pruning should also aim to create separation between plants to slow the spread of fire and eliminate "ladder fuels," which are shrubs growing directly under trees that can allow flames to climb into the canopy.
3. Avoid High-Risk Plants: Refrain from planting juniper, bamboo, fountain grass, eucalyptus, and pine trees near the home, as these ignite easily and can quickly carry flames. Additionally, limit the use of tall ornamental grasses like Pampas grass , and be cautious with other highly flammable plants such as French broom, rosemary, and oleander.
4. Install Efficient Irrigation Systems: Keep high-moisture fire-resistant plants adequately hydrated, especially during the fire season. Drip irrigation is an efficient method that minimizes dry patches. Maintaining appropriate irrigation frequencies can contribute to the fire resistance of plants.
5. Utilize Hardscaping Strategically: Incorporate patios, walkways, gravel beds, and retaining walls into the landscape design, as these can act as effective firebreaks. Choose non-flammable materials such as stone, concrete, or decomposed granite for these features.
Final Thoughts
Implementing fire-resistant landscaping is a proactive and strategic approach to safeguarding homes in wildfire-prone regions. By carefully selecting plant species that are appropriate for the local climate and environmental conditions and by adhering to consistent maintenance practices, homeowners can create a living barrier that significantly enhances their property's defense against wildfires. This strategy, combined with ongoing maintenance, thoughtful design choices, and other fire protection systems, offers the most comprehensive approach to wildfire safety and can contribute to a more beautiful, ecologically sound, and ultimately safer home environment.
