BAER Team Begins Post-Fire Assessment of Bolt Creek Fire near Skykomish, and Boulder Lake, Lake Toketie and Suiattle River Fires near Darrington

A Forest Service Burned Area Emergency Response (BAER) team has been established by the Mt. Baker-Snoqualmie National Forest (MBSNF) to begin post-fire burned area assessments of the Bolt Creek Fire and other wildfires near Darrington that have recently burned on Forest Service federal lands, and private lands. The BAER team leader is Joe Blanchard, Forest Service Watershed Program Manager. Forest Service BAER team assessments typically take approximately two weeks to complete.

BAER teams coordinate with tribal nations, the Washington Department of Natural Resources (DNR), National Weather Service (NWS), US Geological Survey (USGS), 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 to prepare the burned area for winter storms. The team focus is on potential emergency impacts to life and safety on federal land. They also model hydrologic response throughout the burned area and share the team’s findings with the affected downstream agencies.

BAER teams may consist of scientists and specialists including hydrologists, geologists, soil scientists, engineers, botanists, biologists, archeologists, recreation specialists, and geographic information specialists. BAER teams collect field 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 produce post-fire erosion and stream flow models. 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 and sometimes include 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 lands.

BAER reports are shared with interagency cooperators and counties 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/.

BAER SAFETY MESSAGEEveryone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains and increased water runoff. Flash flooding may occur quickly during heavy rain events – be prepared to act. Current weather and emergency notifications can be found at the National Weather Service website: www.weather.gov/sew/.

Soil Burn Severity Maps are now available for the fires. See here for Bolt Creek https://inciweb.nwcg.gov/incident/article/8429/72412/ and here for the Darrington area https://inciweb.nwcg.gov/incident/article/8429/72416/


What is Soil Burn Severity?

We often think of wildfire burn severity in terms of the visual impacts above the ground. Yet, the post-fire landscape response (erosion, flooding, and mass movement) is more strongly correlated to soil burn severity. The BAER team starts by looking at the vegetation to understand conditions and characterize soil burn severity. Then, the team’s watershed specialists (soil scientists, hydrologists, and geologists) ground-truth different vegetation burn intensities to tease out patterns of how fire affected and changed soil properties. Pre-fire ground cover, forest type, fire behavior, slope, aspect, and other factors all influence soil burn severity. After collecting field observations, the team adjusts the vegetation severity map to create the soil burn severity (SBS) map, using four classes: unburned (green), low severity (blue), moderate severity (yellow), and high severity (red).
 

What do these classifications mean?

LOW severity areas generally have intact and recognizable litter layers (organic material on the forest floor, such as pine needles and twigs). These litter layers may be charred, but are not consumed. Underlying topsoil is intact and near-surface fine roots are unburned. These soils have enough cover to protect them from erosion during rain events because their natural porosity and structure allow rain to soak into the soil instead of running off, while fine roots provide stability. In low severity areas, burns may have been patchy—islands of green vegetation and intact canopies may be present. 

MODERATE severity areas generally have more—up to 80% of their pre-fire surface litter layers consumed by fire.  Black or gray ash may be present on the soil surface. Fine roots near the surface may be scorched and killed. Topsoil layers are generally intact with minimal impacts to the soil’s ability to absorb moisture. Soils with moderate severity are more susceptible to erosion in post-fire rain events because they have lost protective surface cover and may have less surface stability because of root mortality.

HIGH severity areas generally have had all their pre-fire surface litter layers consumed by fire. White or gray ash may be present on the soil surface. Fine roots are often fully burned/consumed within several inches of the soil surface, and even large tree roots may have burned deep into the soil. Soil may be powdery or grainy and loose, unable to bind together and retain water. These soils are very susceptible to erosion and often have high surface run-off during rainstorms.

What does the BAER team do with the SBS map?

The BAER team uses the SBS map to predict how the landscape may respond after fires. Soil scientists consider where soil productivity may be degraded due to erosion losses and where sediment may move into stream channels. Hydrologists predict watershed response—surface runoff from high SBS areas in rainstorms can produce more “flashy” behavior in stream systems. Geologists predict debris flow or other mass movement potential based on reduced soil stability in steep drainages.

These predictions help federal land managers implement focused emergency responses to stabilize burned areas that could impact critical infrastructure or other values located within or immediately downstream of moderate and high soil burn severity areas.


Burned Area Emergency Response Limitations

Related Incident: Mt. Baker-Snoqualmie Post-Fire BAER
Publication Type: News

 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.

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.

BAER SAFETY MESSAGEEveryone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains and increased water runoff. Flash flooding may occur quickly during heavy rain events-be prepared to act. Current weather and emergency notifications can be found at the National Weather Service websites: www.weather.gov/sew/.

Key Elements of BAER Assessment

 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.

BAER SAFETY MESSAGEEveryone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains and increased water runoff. Flash flooding may occur quickly during heavy rain events-be prepared to act. Current weather and emergency notifications can be found at the National Weather Service websites: www.weather.gov/sew/.

Three Phases of Wildfire Recovery

Related Incident: Mt. Baker-Snoqualmie Post-Fire BAER
Publication Type: News

THREE PHASES OF WILDFIRE RECOVERY

There are three phases of recovery following wildfires on federal lands:

-       Fire Suppression Repair

-       Emergency Stabilization-Burned Area Emergency Response (BAER)

-       Long-Term Recovery and Restoration

Fire Suppression Repair is a series of immediate post-fire actions taken to repair damages and minimize potential soil erosion and impacts resulting from fire suppression activities and usually begins before the fire is contained, and before the demobilization of an Incident Management Team. This work repairs the hand and dozer fire lines, roads, trails, staging areas, safety zones, and drop points used during fire suppression efforts.

Emergency Stabilization-Burned Area Emergency Response (BAER) is a rapid assessment of burned watersheds by a BAER team to identify imminent post-wildfire threats to human life and safety, property, and critical natural or cultural resources on National Forest System lands and take immediate actions to implement emergency stabilization measures before the first post-fire damaging events. Fires result in loss of vegetation, exposure of soil to erosion, and increased water runoff that may lead to flooding, increased sediment, debris flows, and damage to critical natural and cultural resources. BAER actions such as: mulching, seeding, installation of erosion and water run-off control structures, temporary barriers to protect recovering areas, and installation of warning signs may be implemented. BAER work may also replace safety related facilities; remove safety hazards; prevent permanent loss of habitat for threatened and endangered species; prevent the spread of noxious weeds and protect critical cultural resources.

Long-Term Recovery and Restoration utilizes non-emergency actions to improve fire-damaged lands that are unlikely to recover naturally and to repair or replace facilities damaged by the fire that are not critical to life and safety. This phase may include restoring burned habitat, reforestation, other planting or seeding, monitoring fire effects, replacing burned fences, interpreting cultural sites, treating noxious weed infestations, and installing interpretive signs.

BAER SAFETY MESSAGEEveryone near and downstream from the burned areas should remain alert and stay updated on weather conditions that may result in heavy rains and increased water runoff. Flash flooding may occur quickly during heavy rain events be prepared to act. Current weather and emergency notifications can be found at the National Weather Service website: www.weather.gov/sew/.
