Rapid Wildfire Rehabilitation

The unspoiled landscape of Idaho draws—and awes—hundreds of thousands of visitors each year. From its snow-capped mountains to its steep gorges, the Gem State truly sparkles in the Northwest.

But regular bouts of dryness and wildfires make Idaho, with its picturesque rough terrain and shrubby steppes, especially vulnerable to wildfires. The 2015 wildfire season was a record for the U.S. as a whole, and in Idaho, which suffered its worst fire season in nearly 90 years, the Soda Fire was one of the largest.

The Soda Fire was ignited by a lightning strike on Aug. 10, 2015, and burned across the rugged landscape of southwest Idaho and eastern Oregon. Feeding on sagebrush, cheatgrass, and mountain mahogany, the fire expanded quickly, from 78,000 acres (316 km2) on the morning of Aug. 12, to 120,000 acres (486 km2) by that afternoon.

When Keith Weber, director of the Idaho State University (ISU) GIS Training and Research Center, heard about the fire’s quick growth, he knew what lay ahead. His team’s partnership with the U.S. Department of the Interior’s Bureau of Land Management’s (BLM) Boise District had helped facilitate the use of satellite data for post-fire rehabilitation during active firefighting efforts. “The fire was an unusual one,” Weber remarked. “One of those rapidly moving mega-fires that can be very problematic.”

As the fire quickly expanded, BLM needed immediate access to near-real-time data on the fire’s extent and recent impacts, so its Emergency Stabilization and Rehabilitation team could quickly assess fire damage and identify areas for rapid treatment and restoration. That information came from a mapping system called the Rehabilitation Capability Convergence for Ecosystem Recovery, or RECOVER.

“The land management agencies were doing all the work to fight the fire,” said Weber, who helped develop RECOVER. “What we were doing was supporting them so they could make good decisions quickly about how to fight the fire and, later, how to manage the land after the fire.”

ISU, BLM, and NASA built RECOVER to provide information for rapid remediation during and after wildfires using already-existing satellite data. It does this by creating a single tool that automatically integrates a multitude of data and imagery layers, including current and archived satellite land and infrared image data. The RECOVER system assembles and superimposes the information on top of imagery of burned and burning areas to produce near-real-time updates in an easy-to-use interface, accessible on a standard web browser.

RECOVER gathers up to 20 different datasets—including wildlife habitat and local topography—into one system that helps BLM rehabilitation crews assess the situation more completely and quickly. Before this, remediation crews would have to wait for the fire to be contained and then complete an assessment before submitting a rehabilitation plan. The assessment would include surveying multiple websites for information on soil layers, plant species composition, burn severity mapping, and other data, according to Gregory Mann, a fire ecologist with BLM.

“RECOVER supported our early rapid assessment for rehabbing after the fire even while firefighters were still on the ground.”

That process of collecting information was typically challenging and time-consuming—often taking several days to more than a week to complete. “When we’re dealing with large fires, it’s extremely difficult,” Mann added.

The massive Soda Fire ultimately burned more than 283,000 acres (1,145 km2) across Idaho and Oregon. Crews using RECOVER were able to automatically generate and refresh data while the fire was still actively burning—something that wasn’t possible before.

In fact, by the time the wildfire was contained, rehabilitation crews already had a complete and ready-to-use customized analysis of the Soda Fire. With that data at their fingertips in a matter of minutes, the teams could promptly determine where to target their rehabilitation efforts.

“RECOVER supported our early rapid assessment for rehabbing after the fire even while firefighters were still on the ground,” Karen Miranda, information officer for the Emergency Stabilization and Rehabilitation team said. “Pre-planning before the fire is fully contained helps our work move forward as quickly as possible.”
