When Leaves Fall, Fire Danger Rises
Fall is upon us.  The leaves are turning colors and falling from the trees. Pines, spruce, and other evergreens are in the midst of their seasonal needle drop. Plants and grasses are going dormant, leaving only crispy brown remnants of what was their green, flowering summer glory. As the leaves fall, the risk of wildfires rises.  Dry, windy conditions have resulted in nearly a dozen wildfires in the last week here in Wisconsin.

Wildfires can occur any time of the year when the ground is not snow covered. Wildfires are more likely to start when people burn leaves and brush, leave campfires unattended, dump wood ash outdoors, or operate vehicles or equipment near wildland vegetation. Wildfires are more likely to spread when there is an abundance of dead vegetation around to carry the flames.

In Wisconsin, the top causes of wildfires during the fall of the year are:
1. 27% Equipment (logging or farm machinery, vehicle exhaust or equipment sparks)
2. 25% Debris burning (burning brush, leaves, or trash in burn barrels or on the ground)
3. 9% Improper ash disposal (dumping wood ash from fireplaces, wood stoves, etc. outdoors)
4. 6% each – power lines and incendiary
5. 5% campfires

Keeping leaves swept off the deck reduces the amount of burnable wildland “fuel” next to your home or cabin.

Taking precautions anytime you use fire outdoors is your key to preventing wildfires and paying a hefty suppression bill should you start one. If you use a woodstove or fireplace for heating your home, either empty the ashes into a metal container with a tight-fitting lid or dump the ashes onto bare soil then drown the ash with water and stir until you’re sure no hot embers remain. The same goes for campfires, burn barrels and burned leaf and brush piles – before you leave the area, drown the ashes, stir, and keep adding water until all smoke is gone.

There are simple things property owners can do to protect their home or cabin from wildfire this fall and next spring when wildfire potential is at its greatest. Your “home ignition zone” is your home and its surroundings out to at least 100 feet (up to 200 feet if your home is surrounded by pine trees). Research has shown that the characteristics of buildings and their immediate surroundings determine the risk of them igniting during a wildfire.

Fall is a great time of year to gather fallen branches. Take the brush to a community collection site or create small piles for wildlife habitat.

What can you do?
 Rake up or mow leaves and pine needles
 Remove dead plant material from gardens
 Remove fallen leaves and needles from rain gutters, off the roof, under decks, in window wells and any other place around the home where this debris collects
 Prune evergreen tree branches up and away from the ground
 Compost leaves and garden clippings instead of burning
Keep aware of the fire danger year-round by bookmarking the DNR’s fire Web page: dnr.wi.gov, search “fire”.

Warm, dry weather predicted for the next few days will increase fire danger across the state. So far this year 225 fires have burned 442 acres in DNR protection areas (approximately half the state); 7 buildings have been destroyed and another 120 homes and other buildings have been threatened but saved with firefighter assistance.  Debris burning has been the most common cause (42 percent of all fires) even as burning permits have been suspended. Equipment has been the second most common cause (23 percent of all fires). Other minor causes include power line, railroads, campfires, and ash disposal. As the vegetation dries out on the days we don’t receive rain, expect fire danger to increase, particularly in areas where standing dead grass and other dry vegetation remains.

May 5th will be the 15th anniversary of the Cottonville Fire, which burned 3,410 acres in Adams County. The fire burned a swath of forest land and residential property 1.5 miles wide and 7 miles long; 90 buildings were destroyed, including 9 year-round homes, 21 seasonal homes, and 60 outbuildings. The fire was started by a person who failed to follow burning permit restrictions.

Stay aware of the fire danger in spring by checking our fire danger webpage at dnr.wi.gov (search ‘fire danger’). Put off any outdoor debris burning until burning permit suspensions have been lifted – compost or haul the material to a community collection site instead.

A chimney remains after the Cottonville Fire destroys the rest of the home.

Firewise Tip: Homeowners in high risk areas are encouraged to make weekly checks around your home for windblown leaves and needles on your roof, around your foundation, and under decks and elevated porches; keep these areas clean. The debris that collects in these places could be easily ignited by flying embers produced during a wildfire.

It’s Wildfire Prevention Week, and we’re here to remind you that spring in Wisconsin is fire season!

In the last week, there were nearly 50 wildfires across the state. Strong, gusty winds, low humidity and dry conditions mean that fire danger throughout Wisconsin remains Very High today and tomorrow (4/20-4/21). Although rain is in the forecast, grasses and other vegetation can dry out very quickly allowing fires to escape and grow rapidly.

Wildfires pose a serious threat to public safety, property and our natural resources.  Over 98% of all wildfires in Wisconsin are caused by people.  Debris burning is the No. 1 cause of wildfires in our state. If danger is elevated, high or very high, avoid burning of any kind, including campfires. Be aware of sneaky causes of wildfires – like sparks or hot exhausts systems from logging, farming equipment and off-road recreational vehicles.

On April 18, 2020 a 234-acre wildfire occurred in Juneau County near Necedah.  The wildfire burned on private property and on the Necedah Wildlife Refuge. The wildfire was caused by someone debris burning in a campfire ring. Five structures were threatened but were saved.  Residents needed to be evacuated but were allowed to return home late that afternoon.  Fire Danger was Very high.

DNR burning permits continue to be suspended in Wisconsin.  All burning of debris in barrels, burning of debris piles on the ground, grass or wooded areas, in DNR protection areas, is prohibited at this time

Remember, wildfires have many causes.  Don’t be one of them!
