The Telegraph Fire burned over portions of the Arizona Trail.

Fire can destabilize rocks and other debris on hill slopes above the trail, which may pose a hazard to trail users.

Where the trail follows dry washes, increased post-fire run-off is expected.

Users should be aware of the weather, and avoid dry washes during periods of high-intensity rainfall."

         

TELEGRAPH-MESCAL SOIL BURN SEVERITY MAP RELEASED

Interagency Burned Area Emergency Response (BAER) specialists recently completed their data gathering and analysis for the Telegraph and Mescal burned areas to produce a soil burned severity map.  This map and data display categories of unburned/low, moderate, and high. Approximately 81% of the 263,619 acres (185,102 acres for the Telegraph Fire and 78,517 acres for the Mescal Fire) are either unburned and/or low soil burn severity, while 18% sustained a moderate soil burn severity, and only about 1% identified as high soil burn severity.

The low category of soil burn severity indicate that there was only partial consumption of fine fuels and litter coverage still remains, to some extent, on the soil surface.  Residence time at the soil surface in low areas was short, leaving root systems and structure intact.  Recovery time in the low category will vary based on ecological community but is expected to be relatively short.

A moderate category of soil burn severity indicates consumption of litter and fine fuels at the soil surface.  In forested communities, the heat from moderate severity fire will result in water repellant conditions at the mineral soil surface.  The canopy in the moderate forested system is browning and it is expected that trees in this area will drop needles and leaves that can provide some litter cover at the soil surface.  In these systems, recovery can take longer for tree species to reestablish.

The moderate soil burn severity category in lower elevation communities indicates complete consumption of shrub cover that can but does not necessarily result in water repellant conditions at the soil surface.  Several shrub species in the lower elevation communities do root crown after fire and recovery time will be variable. Moderate soil burn severity category in the lower elevation shrub communities that did not express water repellant behavior can still result in a runoff potential category of high as a result of the soils inherent qualities and the removal of effective vegetative cover.

A high soil burn severity category is the result of higher intensity fire behavior or longer residence time at the soil surface.  This category is found in forested or dense Woodland communities and the litter and fuels, including an overstory canopy, was consumed.  The soil structure is weakened, roots are charred, and water repellant soil conditions persist through the upper horizon of mineral soil.  Recovery time in the conifer systems can be significant.

The Telegraph and Mescal BAER assessment teams used initial remote sensing imagery with their field validated soils data, to develop and produce a map showing soil burn severity levels for the burned areas within both wildfires.  The BAER teams and the US Geological Survey (USGS) both utilized the soil burn severity map as an analysis tool to estimate post fire flows and debris flow probability. 

The BAER team relied on their refined soil burn severity map to produce data which they are using in their subsequent modeling and determination of post fire runoff and sedimentation. In specific areas that experienced moderate to high burn severity, there could be increased runoff from steep hillslopes and resultant increases in post-fire soil erosion and potential debris flows.

The Telegraph-Mescal soil burn severity map can be downloaded at the interagency “Telegraph Post-Fire BAER” and “Mescal Post-Fire BAER” InciWeb sites (https://inciweb.nwcg.gov/incident/7560/ and https://inciweb.nwcg.gov/incident/7573/) as a JPEG or PDF version under the “Maps” tab.

SPECIAL NOTE: Everyone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains over the burn scars. Flash flooding may occur quickly during heavy rain events be prepared to take action.

First two photos are of BAER Engineer Ernesto and BAER Hydrologist Kelly checking culverts on the Pioneer Pass Road–we do this to see if the culverts have sufficient capacity to pass post-fire flows–in particular we look to see if they are clogged or collapsed. 
The next photo is BAER Engineer Ernesto measuring the clearance of the bridge on Pinto Creek to make sure there is adequate clearance for post-fire debris flows. 
The last photo is BAER Hydrologist Kelly checking soil burn severity–in particular testing for if the soil is hydrophobic – aka repels water. This is important because the amount of hydrophobicity is an important component to determining how much increased runoff we can expect after a fire.

    

INTERAGENCY BAER TEAMS BEGIN

POST-FIRE ASSESSMENTS

Three Burned Area Emergency Response (BAER) teams have been established by the Tonto National Forest (NF), the Bureau of Land Management (BLM), and the Bureau of Indian Affairs (BIA) to begin burned area assessments of the Telegraph and Mescal wildfires that recently burned on state, private, tribal, and federal lands.  The Tonto NF BAER team leader is Mike Martinez, who is its Forest’s Ecosystems Staff Officer, Chris Holbeck, a biologist with the National Park Service leads the Department of Interior BAER team, while Fish & Wildlife Service Wildlife Biologist Ken Griggs is the team leader for the BIA BAER assessment team. 

In addition to working and coordinating with each other, the teams also coordinate with the San Carlos Apache Tribe, USDA Natural Resources Conservation Service (NRCS), National Weather Service (NWS), US Geological Survey (USGFS), Arizona Geological Survey (AZGS), and other federal, state and local agencies as they assess potential post-fire impacts to the burned watersheds.

BAER surveys are rapid assessments that evaluate the burned area to identify watersheds having increased potential for post-fire flooding, sediment flows and rockslides, and assist land managers prepare the burned area for the upcoming monsoon rains.  The team will focus on potential emergency impacts to life, and safety on federal and tribal land and share the team’s findings with the responsible downstream agencies.

BAER teams may consist of scientists and specialists including hydrologists, geologists, soil scientists, road engineers, botanists, biologists, archeologists, and geographic information specialists.  BAER teams collect data during their burned area surveys to analyze through GIS and computer models and present their findings along with recommended BAER emergency stabilization treatments in a BAER assessment report.

BAER teams utilize satellite imagery and specialist data to analyze and produce a runoff map that shows the levels of hydrological potential flows during rain events.  This is the first step in assessing potential watershed impacts from wildfires to any federal values that may be at-risk from potential increased flooding, sedimentation, debris flows, and rockslides.  BAER teams produce a report that describes ​potential threats associated with the burned area’s post-fire conditions sometimes including recommended emergency stabilization measures and actions.  BAER emergency response efforts are focused on the protection of human life, safety and property, as well as critical cultural and natural resource values such as the water quality of streams and wetlands on federal and tribal lands.

Rainstorm run-off is sometimes, but not always increased on burn scars. BAER reports are shared with interagency cooperators who work with downstream private home and landowners to prepare for potential post-fire flooding and debris flow impacts.  Homes or businesses that could be impacted by flooding from federal land that resulted from wildfires may be eligible for flood insurance coverage from the National Flood Insurance Program (NFIP).  Information about NFIP is available through FEMA at www.fema.gov/national-flood-insurance-program, or www.floodsmart.gov/wildfires. Other flood preparedness information is available at www.ready.gov/floods at www.floodsmart.gov/.

SPECIAL NOTE: Everyone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains over the burn scars. Flash flooding may occur quickly during heavy rain events be prepared to take action. Current weather and emergency notifications can be found at the National Weather Service website: https://www.weather.gov/psr/.

Burned Area Emergency Response (BAER) Limitations

While many wildfires cause minimal damage to the land and pose few threats to the land or people downstream, some fires result in damage that requires special efforts to reduce impacts afterwards. Loss of vegetation exposes soil to erosion; water run-off may increase and cause flooding, soil and rock may move downstream and damage property or fill reservoirs putting community water supplies and endangered species at-risk.

The Burned Area Emergency Response (BAER) program is designed to identify and manage potential risks to resources on National Forest System lands and reduce these threats through appropriate emergency measures to protect human life and safety, property, and critical natural or cultural resources. BAER is an emergency program for stabilization work that involves time-critical activities to be completed before the first damaging storm event to meet program objectives.

BAER Objectives:

• Determine whether imminent post-wildfire threats to human life and safety, property, and critical natural or cultural resources on National Forest System lands exist and take immediate actions, as appropriate, to manage the unacceptable risks.
• If emergency conditions are identified, mitigate significant threats to human life and safety, Forest Service property and other critical natural and cultural resource values.
• Prescribe emergency response actions to stabilize and prevent unacceptable degradation to natural and cultural resources, to minimize threats to life or property resulting from the effects of a fire, or to repair/replace/construct physical improvements necessary to prevent degradation of land or resources.
• Implement emergency response actions to help stabilize soil; control water, sediment and debris movement and potentially reduce threats to the BAER critical values identified above when an analysis shows that planned actions are likely to reduce risks substantially within the first year following containment of the fire.
• Monitor the implementation and effectiveness of emergency treatments that were applied on National Forest System lands.

BAER Interagency Coordination:

Post-fire emergency response is a shared responsibility. There are several Federal, State and local agencies that have emergency response responsibilities or authorities in the post-fire environment. The BAER team coordinates with these agencies to look at the full scope and scale of the situation to reduce the potential threats to human life and property. It is important that BAER efforts are communicated with all affected and interested cooperating agencies and organizations regarding other post-fire recovery and restoration efforts.

BAER treatments cannot prevent all of the potential flooding or soil erosion impacts, especially after a wildfire-changed landscape. It is important for the public to stay informed and prepared for potentially dramatic increased run-off events.

One of the most effective BAER strategies is interagency coordination to provide post-fire threat information to local cooperators who can assist affected businesses, homes, and landowners to prepare for rain events. For example, the Natural Resources Conservation Service (NRCS) has the Emergency Watershed Protection (EWP) program for post-emergency assistance on private and tribal land, the National Weather Service (NWS) has responsibility for flood warning alerts, the Federal Emergency Management Agency (FEMA) has flood insurance and other responsibilities if the area is a Presidentially-declared emergency, Resource Conservation Districts (RCD) and counties, as well as State and local-highway and emergency services departments, Flood Control authorities, etc. It is important that landowners work directly with NRCS and other agencies to determine appropriate actions needed to protect private structures and other assets.

BAER Process:

BAER assessment teams are staffed by specially trained professionals that may include: hydrologists, soil scientists, engineers, biologists, botanists, archeologists, and others who evaluate the burned area and prescribe temporary emergency stabilization actions on National Forest System lands to protect the land quickly and effectively. BAER assessments usually begin before a wildfire has been fully contained.

A BAER assessment team conducts field surveys and uses science-based models to rapidly evaluate and assess the burned area and prescribe emergency stabilization measures. The team generates a “Soil Burn Severity” map by using satellite imagery which is then validated and adjusted by BAER team field surveys to assess watershed conditions and model potential watershed response from the wildfire. The map identifies areas of soil burn severity by categories of very low/unburned, low, moderate, and high which may correspond to a projected increase in watershed response. The higher the burn severity, the less the soil will be able to absorb water when it rains. Without absorption, there will be increased run-off with the potential of flooding.

The BAER team presents these findings in an assessment report that identifies immediate and emergency actions needed to address post-fire risks to human life and safety, property, cultural and critical natural resources. This includes early detection and rapid response (EDRR) treatments to prevent the spread of noxious weeds into native plant communities. The BAER report describes watershed pre- and post-fire watershed response information, areas of concern for life and property, and recommended short-term emergency stabilization measures for Forest Service lands that burned.

In most cases, only a portion of the burned area is actually treated. Severely burned areas steep slopes, and places where water run-off will be excessive and may impact important resources, are focus areas and described in the BAER assessment report if they affect critical values. Response action timing is essential to ensure the emergency stabilization measures are effective.

There are a variety of emergency stabilization actions that the BAER team can recommend for Forest Service land such as mulching with agricultural straw or chipped wood to protect soil productivity, increasing road drainage to keep roads and bridges from washing-out during post-fire floods, and early detection rapid response invasive plant treatments to prevent spread of weeds into native plant communities. BAER treatments are preventative in nature but cannot prevent all damage, especially debris torrents in areas that are prone to sliding and have lost critical root structure from plants.

The Cans and Cannots of BAER:

What BAER Can Do:

• Install water or erosion control devices
• Seed or mulch for erosion control or stability reasons
• Install erosion control measures at critical cultural sites
• Install temporary barriers to protect treated or recovering areas
• Install warning signs
• Replace minor safety related facilities, like burned guard rails
• Install appropriate-sized drainage features on roads, trails
• Remove critical safety hazards
• Prevent permanent loss of T&E habitat
• Monitor BAER treatments
• Implement EDRR treatments to minimize the spread of noxious weeds into native plant communities

What BAER Cannot Do:

• Prevent all flooding and debris flows
• Replant commercial forests or grass for forage
• Excavate and interpret cultural sites
• Replace burned pasture fences
• Install interpretive signs
• Replace burned buildings, bridges, corrals, etc.
• Repair roads damaged by floods after fire
• Remove all hazard trees
• Replace burned habitat
• Monitor fire effects
• Treat pre-existing noxious weeds

BAER Funding:

Special Emergency Wildfire Suppression funds are authorized for BAER activities and the amount of these expenses varies with the severity of the fire season. Some years see little BAER activity while other years are extremely busy.

Because of the emergency nature of BAER, initial requests for funding of proposed BAER treatments are supposed to be submitted by the Forest Supervisor to the Regional Office within7 days of total containment of the fire. The Regional Forester’s approval authority for individual BAER projects is limited. Approval for BAER projects exceeding this limit is forwarded onto the Washington Office.

 KEY ELEMENTS OF A BAER ASSESSMENT 

                              
Forest Service BAER assessment teams are established by Forest Supervisors before wildfires are fully contained. The teams coordinate and work with the USDA Natural Resources Conservation Service (NRCS), Bureau of Land Management (BLM), Fish & Wildlife Service (FWS), National Weather Service (NWS), local counties, State Department of Transportation, and other federal, state, and local agencies to strategically assess potential post-fire impacts to the watersheds burned from wildland fires.

·       The BAER assessment teams are evaluating watershed conditions to determine the level of potential risks to human life, safety, property, critical natural and cultural-heritage resources, and determine if there are appropriate and effective emergency stabilization measures that can be implemented on federal lands in a timely manner to reduce unacceptable risks from potential flooding and debris flow threats.

·       The BAER assessment team conducts field surveys and uses science-based models to rapidly evaluate and assess the burned area.

·       BAER assessment teams are staffed by specially trained professionals that may include: hydrologists, soil scientists, engineers, geologists, biologists, botanists, archeologists, geographic information system mapping specialists, recreation and trails specialists, and others who evaluate the burned area and prescribe emergency response actions to protect the land quickly and effectively.

·       BAER assessments usually begin before a wildfire has been fully contained.

·       The BAER assessment team generates a “Soil Burn Severity” map by using satellite imagery which is then validated and adjusted by BAER team field surveys to assess watershed conditions and watershed response to the wildfire. The map identifies areas of soil burn severity by categories of low/unburned, moderate, and high which corresponds to a projected increase in watershed response.

·       The BAER team presents these findings and treatment recommendations to the Forest Supervisor in an assessment report that identifies immediate and emergency stabilization actions needed to address potential post-fire risks to human life and safety, property, cultural-heritage and critical natural resources on National Forest System lands.

·       The BAER report describes watershed pre- and post-fire response information, areas of concern for human life, safety and property, and recommended short-term emergency stabilization actions for federal lands that burned.

·       In most cases, only a portion of the burned area is actually treated.

·       If the BAER assessment team determines there may be potential emergency situations, the short-term goal is to have flood and erosion control protection measures completed before the first large, damaging rain events occur.

·       Timely implementation is critical if BAER emergency response actions are to be effective.

·       The BAER assessment team coordinates with other federal and local agencies, and counties that assist private landowners in preparing for increased run-off and potential flooding.

·       Federal assistance to private landowners regarding post-fire potential impacts is the primary responsibility of the NRCS through the Emergency Watershed Protection (EWP) program (www.nrcs.usda.gov/wps/portal/nrcs/main/national/programs/landscape/ewpp/).

·       NRCS in coordination with additional state, local and federal agencies conduct damage survey reports for the private land adjacent to and downstream from the burned areas. NRCS uses these reports, along with the BAER team’s assessment report, to develop recommended emergency measures for businesses and private home and landowners to reduce the impacts to their property from potential increased water and debris flows.

SPECIAL NOTE: Everyone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains over the burn scars. Flash flooding may occur quickly during heavy rain events-be prepared to take action. Current weather and emergency notifications can be found at the National Weather Service website: www.weather.gov/sgx/.

FOREST SERVICE BAER PROGRAM OVERVIEW
