Wildfire is part of life in Paradise Valley. Dry grasses along the river, sage steppe on the benches, and conifer stands on the slopes make a mix of fuels that can carry both fast-moving grass fires and hotter forest fires. Creating defensible space is the single best step you can take to protect your home, your family, and your investment.
Why does this matter here? Local fire history and planning documents highlight the valley’s wildland-urban interface and the potential for stand-replacing fire in certain forest types. Recent incidents, including a fast-moving grass fire near I‑90 and Livingston, show how quickly conditions can change on a windy day local CWPP context and news of a Livingston-area wildfire.
Why defensible space matters for mountain homes
Defensible space is the managed area around your buildings that reduces ignition risk when embers fall and when fire moves across the ground. In our landscape of grasses, sage, cottonwoods, and conifers, embers can travel far ahead of flames and find weak spots around your home. Studies show most homes ignite from embers and conditions within the Home Ignition Zone, not a towering wall of flame how embers ignite homes.
Done well, defensible space supports life safety, helps firefighters work your property, improves insurability, and shows good stewardship of the land. It also reassures future buyers that the home is cared for and ready for Montana’s fire season.
Assess your property’s wildfire risk
Before you start cutting or hauling, take a slow walk. Note structures, decks, fences, vegetation types, slopes, and access points. The mix of fuels around Livingston and Paradise Valley ranges from grass and sage to ponderosa pine and pockets of lodgepole or Douglas‑fir at higher elevations local vegetation and fuel types.
Home hardening priorities
Start with the house, then work outward. Small fixes here have outsized impact.
- Clean roofs and gutters. Remove needles, leaves, and debris. Repeat after wind events DNRC home prep guidance.
- Screen vents with 1/8 inch metal mesh. Check attic, crawlspace, and eave vents for gaps where embers could enter roof and vent best practices.
- Use fire-resistant roofing when you re-roof. Keep decks and porches free of combustible storage.
- Replace or isolate wooden fencing where it attaches to the house.
Landscape and fuels inventory
Walk the yard and acreage with three questions in mind:
- Is there continuous fuel from the grass up into shrubs and tree branches? Those are ladder fuels.
- Are shrubs and trees crowded so fire can move crown to crown?
- Where can you break up fuels with paths, gravel, irrigated lawn, driveways, or natural rock outcrops?
Slope, aspect, and access considerations
Fire moves faster uphill. South and west slopes dry out sooner. On steeper ground or below ridgelines, you should increase spacing and extend defensible space farther than the basic numbers. Also check access. Make sure long driveways allow turnarounds and have solid address signage so responders can find you quickly technical defensible space guidance.
Build defensible space in manageable zones
Fire agencies use the Home Ignition Zone concept. Think of three zones around your buildings. These distances are common starting points, then adjust for slope and fuels overview of HIZ and DNRC zone basics.
Immediate zone around the home
Zone A: 0 to 5 feet. This is the most important area. Keep it noncombustible.
- Use gravel, stone, or concrete up to the foundation. Avoid bark or wood mulch against the house spacing and materials basics.
- Keep this zone free of shrubs, stacked firewood, and stored gear.
- Enclose undersides of decks and steps or keep them clear of debris.
Intermediate zone near the home
Zone B: 5 to 30 feet. The goal is to lower flame length and heat.
- Break up plantings into small, well-spaced islands with paths or turf between them.
- Prune trees to raise canopies. Maintain vertical separation between shrubs and the lowest tree branches. A useful rule is to keep at least three times the shrub height of clearance between shrub tops and tree limbs slope and spacing ideas.
- Move propane grills, wood piles, and fuel cans away from the house.
Extended zone across the property
Zone C: 30 to 100 feet, or to the property line. Here you work on spacing and fuel breaks so a surface fire stays on the ground and slows down.
- Thin trees and remove ladder fuels, especially small conifers growing under larger crowns.
- Aim for clear gaps between tree canopies. In the near part of this zone, many guides suggest 6 to 12 feet of canopy separation, increasing with slope extended zone guidance.
- Use driveways, gravel aprons, irrigated lawn, and paths to break up fuels.
- In grassland areas, keep grasses mowed short and clear around outbuildings and propane tanks. A 10 foot bare or green zone around tanks and sheds is a common recommendation CAL FIRE defensible space.
Trees, shrubs, and groundcovers
- Favor plants with higher moisture content and lower resin. Avoid dense plantings of juniper or other highly resinous shrubs right next to structures.
- Keep shrubs small and separated. Prune trees every year to maintain vertical and horizontal spacing.
- In our climate, native bunchgrasses and irrigated lawn can serve as low-fuel breaks when kept green and short near the home local plant community context.
Outbuildings, decks, and fences
- Store firewood at least 30 feet from the house, farther on slopes.
- Create a 10 foot clear zone around propane tanks and outbuildings.
- Where wood fencing connects to the house, replace the last section with metal or another noncombustible material practical measures.
Maintain defensible space year-round
Defensible space is not one and done. A simple seasonal rhythm makes it manageable.
Spring preparation checklist
- Clean roofs, gutters, and under-deck areas.
- Rake and remove winter debris from the 0 to 30 foot areas.
- Prune trees for clearance and remove deadwood.
- Service chainsaws, trimmers, and chippers. Schedule contractors early.
- Walk the driveway. Trim back overgrowth and confirm address signage DNRC prep basics.
Summer monitoring routine
- After wind events, re-check roofs, gutters, and corners where debris collects.
- Keep grasses short near structures. Move combustibles away from the house.
- Water key plantings as allowed to maintain green islands near the home.
- Avoid mechanical work on hot, windy days or during red flag warnings seasonal safety tips.
Fall cleanup and fuel reduction
- Mow and remove cured grasses near buildings.
- Thin small conifers and remove ladder fuels in the 30 to 100 foot zone.
- Chip or haul slash. If considering burning, first check county rules and permits Park County Fire Warden info.
Winter planning and upgrades
- Price out home hardening projects like ember-resistant vents and siding repairs.
- Map next year’s thinning and spacing goals. Flag trees for a forester to review.
- Line up contractors before spring demand spikes.
Permits, contractors, and project costs
Paradise Valley parcels range from small river lots to large acreages. Match the approach to your site and comfort level.
DIY vs. hiring mitigation professionals
- Good DIY tasks: gutter cleaning, debris removal, light pruning, mowing, moving combustibles, creating the 0 to 5 foot noncombustible zone.
- Consider pros for: large tree removals, steep-slope thinning, high-ladder pruning, complex access work, or projects near power lines.
- Keep before-and-after photos and receipts. They help with insurance reviews and potential grant applications project documentation tips.
Choosing qualified contractors
- Ask for proof of insurance and worker’s comp.
- Check references and confirm the scope in writing.
- Look for experience in fuels reduction, not just ornamental pruning.
Debris and slash disposal options
- Chipping on-site and spreading chips in thin layers away from structures.
- Hauling to green-waste facilities when available.
- Pile burning only when allowed and safe, with proper permits and control measures. Always verify current county restrictions before burning Park County burn permits.
Budgeting and potential incentives
- Phase work by zone: start with the house and 0 to 30 feet, then expand outward.
- Ask your local fire district about chipper days and community programs.
- Explore state and federal assistance that flows through DNRC and local partners, such as Community Wildfire Defense Grants and related cost-share efforts DNRC grants info.
Insurance and resale benefits of mitigation
How mitigation influences coverage
Insurers look at roofing, defensible space, access, and water sources. Clean roofs and gutters, a noncombustible 0 to 5 foot zone, trimmed trees, and visible address signage show a lower-risk property. Keep records and photos of your work.
Pre-listing curb appeal and buyer confidence
Prepared properties show better and sell with fewer objections. Buyers can see clear access, tidy grounds, and cared-for structures. In a valley where wildfire is a known risk, a clean Home Ignition Zone gives confidence.
Document your work for future value
Create a simple property file: dates, contractors, receipts, maps, and photos. Note alignment with the county CWPP or fire district recommendations. If your neighborhood coordinates work, keep a copy of the community plan or flyer CWPP context.

FAQs
What is the Home Ignition Zone and why start there?
- It is the home and the surrounding area out to about 100 feet, where most ignitions occur from embers and radiant heat. Work from the house outward for the biggest impact HIZ overview and ember ignition basics.
What distances should I use for defensible space?
- Common guidance is 0 to 5 feet noncombustible, 5 to 30 feet reduced fuels, and 30 to 100 feet thinned and spaced. Increase distances on slopes or in dense fuels DNRC guidance and extended zone details.
How do slope and wind affect my plan?
- Fire moves faster uphill and with the wind. On steeper slopes, increase spacing and extend your defensible space, especially on the downhill side and near ridgelines slope adjustments.
Are there local rules or permits I should know about?
- Yes. Park County manages burn permits and seasonal restrictions. Always check with the Fire Warden or your local district before burning slash or piles county fire information.
What are the highest-impact, low-cost steps I can do this week?
- Clean roofs and gutters, screen vents, clear the 0 to 5 foot zone, move firewood away, and prune or remove ladder fuels near the home quick-win checklist and DNRC basics.
Who can inspect my property and answer local questions?
- Start with your local fire district or the Park County Fire Warden. Many offer free or low-cost defensible-space inspections and education, plus updates on chipper days and restrictions local contacts and CWPP background.
What should I do with slash and debris?
Can I get help paying for mitigation?
- Some projects qualify for cost-share or grants that flow through DNRC and partners. Ask the Fire Warden about current programs and review DNRC resources for grant pathways DNRC grants.
