Wildfire season begins across northern Arizona

The Snake Ridge fire northwest of Clint Wells, AZ was started by lightning. The USFS is managing the fire and allowing it to burn for forest restoration.

The Snake Ridge fire northwest of Clint Wells, AZ was started by lightning. The USFS is managing the fire and allowing it to burn for forest restoration.

A lightning-caused fire and three human-caused fires over Memorial Day weekend ushered in wildfire season in northern Arizona.

The Snake Ridge fire, a lightning-caused fire northwest of Clint’s Well on Coconino National Forest, was called in by the Baker Butte Lookout May 19 and is now being managed by firefighters and allowed to burn. A Type 3 Incident Management Team was assigned to the fire with approximately 90 firefighters involved.

A fire on Mars Hill near Flagstaff was believed to be human-caused and another fire, near Mountainaire was, found to be caused by an abandoned campfire, one of 77 abandoned campfire reported by Coconino National Forest officials over the Memorial Day weekend.

As temperatures rose into the 80s, and dry and windy conditions with low humidity persisted, Kaibab National Forest fire managers issued their first Red Flag Warning of the season May 25, advising forest users to refrain from having campfires until the warning was lifted that evening.

At the lower elevations, forest officials implemented Stage 1 campfire and smoking restrictions on Prescott National Forest and most of the Red Rock Ranger District of Coconino National Forest June 1 because of dry conditions and high temperatures.

“The dry condition of vegetation across much of the Central Highlands of Yavapai County, including the Prescott National Forest, is climbing steadily above average, trending toward very high or extreme conditions,” said Pete Gordon, Fuels, Fire, & Aviation staff officer for the Prescott National Forest in a news release.

Under Stage 1 restrictions, fires, campfires, charcoal, coal and wood stoves are only allowed in specific developed recreation sites. No campfires are allowed in undeveloped areas. The restrictions also limit smoking to within enclosed vehicles or buildings or in listed developed recreation sites.

As always, fireworks are prohibited on all national forests.

Gordon said the winter and spring precipitation brought much needed relief from the drought, but also brought an abundance of grasses.

“These grasses are now tall and curing, making them quickly available for fast moving wildfires,” he said.

Gordon said the decision to implement Stage 1 restrictions was made in partnership with nearby agencies such as the Bureau of Land Management, Arizona Department of Forestry and Yavapai County Emergency Services,

“Just as we collaborate in training together; responding to wildfires together; and treating the hazardous fuels together; we also communicate frequently this time of year specifically to understand the conditions and coordinate the need for fire restrictions,” he said.

On Coconino National Forest, Stage 1 restrictions apply only to specific areas of the Red Rock Ranger District, including the national forest land in the Verde Valley on the east side of the Verde River, Oak Creek Canyon, lower Sycamore Canyon, lower West Clear Creek, Fossil Creek and Bullpen. The area southeast of Interstate 17, east of Forest Road 618 and north of Forest Road 214 is not included.

“Spring weather provided for a larger grass crop and fine fuels growth this year. With the current lack of moisture and rising temperatures, the potential for wildfire in these lower elevations has increased, which is why we’re going into restrictions,” said Red Rock District Ranger Nicole Branton in a May 31 media release.

Developed recreation sites on the Red Rock Ranger District where campfires, woodstove and charcoal fires will still be allowed include Cave Springs, Clear Creek, Manzanita, Pine Flat and Chavez Group Site Campgrounds, and Crescent Moon Cabin and Grasshopper Point Day-Use Site.

Fire restrictions typically remain in effect until the forests receive significant precipitation, at which time they will be rescinded.

Forest officials would also like to remind forest users that building and maintaining a campfire on the National Forest while under fire restrictions is a violation that carries a mandatory appearance in federal court. Violations are punishable by a fine of not more than $5,000, imprisonment of not more than six months, or both.

2016 Kaibab fire season

Kaibab National Forest received 21.3 inches of precipitation in 2016, which was 136 percent above the average of 15.64 inches. The majority of precipitation came as rain.

Forest managers reported 101 wildfires in 2016, which was nearly the same as the 102 reported in 2015. The 10-year average is 120 starts.

There were 22 human-caused fires in 2016 as compared to 12 in 2015. This is in line with the 10-year average of 22.4 per year.

Lightning-caused starts were down with 79 in 2016 compared with 90 in 2015. This is 18 percent below the 10-year average of 97 lightning-caused starts per year.

The Kaibab had 101 fire starts, which was almost the same as 2015 with 102 starts. This is down by 16 percent from the 10-year average of 119.8 starts.

The 101 fire starts burned a total of 20,622 acres. Managers took suppression action on 94 of the starts, which burned a total of 1,573 acres.

15,316 acres were treated with prescribed fire in 2016. This was the second largest amount of acres ever accomplished and was 84 percent above the 10-year average of 8,331 acres.

Summer fire outlook

On May 1, the Predictive Services section at the National Interagency Fire Center (NIFC) issued their Wildland Fire Potential Outlook for May through August.

According to the NIFC graphical outlooks for May through August, the Drought Monitor, and NOAA’s temperature and precipitation forecasts, Arizona will see an increase in fire activity in June as the region enters the heart of the fire season.

Heavy growth of fine fuels across southern Arizona have led to above normal fire potential along the Mexican border that should persist through June until the monsoonal rains arrive.

As the fire season progresses into July, there are concerns with the seasonal shift west and north into California, and the Great Basin. Exceptional winter and early spring precipitation is leading to the development of a substantial crop of fine fuels in the lower and middle elevations. The heavy loading of fine fuels could become problematic when they cure out in July.

In the higher elevations, the mountain snowpack continues to melt at a normal to slower than normal rate. This should produce a delay in the onset of significant fire activity in the high elevations.
