There is a broad range of [[Fire issues in California's Central Coast Region|resources at risk]] after wildfires.

Of Concern in the Carmel Valley is the possibility that the fire may lead to a sizable influx of sediment behind the Los Padres dam.  This is the only effective storage facility for flood control and dry season conservation releases on the Carmel River.
+
 
+
Steelhead are of particular concern due to their threatened status.  The fire is expected to result in an increased load of fine sediments and debris in the years immediately following.  This will likely reduce spawning habitat in the short term, but periodic influxes of large woody debris are considered beneficial in the long run because they help maintain structural habitat diversity in streams. The likely net impact on the struggling local steelhead populations is unknown. <ref name="BAER report">[http://www.fs.fed.us/r5/lospadres/fire/baer/gallery/basin-rehab.pdf Basin-Indians Fire BAER Report]</ref>

Assessment of the burned area fell under the jurisdiction of the [[United States Forest Service (USFS)|US Forest Service]] and [[California Forestry and Fire Protection (CAL FIRE)| California Forestry and Fire Protection (CalFire)]]. CalFire was the lead agency for the assessment. The policies of both agencies are to provide rapid assessments of the burned areas and suggest best management practices to avoid further damage from erosion and [[Landslides and Debris Flows in the California Central Coast Region|debris flows]].
There are two pieces of legislation that dominate national policy regarding wildfire management. The National Forest Plan was a federal policy responding to the growing concern of dangerous levels of fuels in national forests. The main focuses of the plan are firefighting, rehabilitation, hazardous fuel removal, community assistance and accountability.  The original plan released $108 million for fuels removal in 2000; this number increased to $401 million by 2005.

+
To identify where funds were most necessary, a Ten Year Comprehensive Strategy directed the collaborations of local, tribal, state, and federal land mangers along with scientific and regulatory agencies. The four goals of the plan are improved information sharing, monitoring of accomplishments and forest conditions to improve transparency, a long-term commitment to maintaining the essential resources for implementation, a landscape-level vision for restoration of fire adapted ecosystems, and an emphasis on the importance of using fire as a management tool (Ten Year Comprehensive Strategy 2006).

A watershed-related issue examined by the ENVS 560/L Watershed Systems class at CSUMB.

Basin Complex burn area, 2008[1]

Summary

In the summer of 2008, the Indians and Basin Complex fires started separately and then merged into one fire. The Indians fire, started by a campfire, burned 81,378 acres of the south eastern Santa Lucia mountains of Central California between June 8th and July 10th. The Basin Complex Fire, started by lightning, burned 162,818 acres of the northern Santa Lucia mountains between June 21st and July 28th[1]. After a wildfire there is major concern about the possibility of flooding, debris flows and other large scale erosion in the years following the fires[2]. These events potentially endanger the Big Sur and Carmel Valleys, Salinas farm land, steelhead habitat, Highway 1 and numerous federal and state recreation areas. There has been work aimed at understanding the effects of fire on soils, debris flows and erosion. There is little understanding of the effects of post-fire erosion and debris flows on river habitat, and specifically steelhead habitat.

Location

The Basin Complex-Indians Fire burned approximately 240,000 acres in the northern Santa Lucia Mountains. The fire burned parts of the Upper Carmel River, Arroyo Seco, San Antonia, Rat Creek, Big Sur and Little Sur watersheds. and portions of Fort Hunter Liggett. Much of the land burned is within the National Forest System lands on the Monterey District of Los Padres National Forest[1].

Resource/s at Stake

There is a broad range of resources at risk after wildfires. Risks related to the Basin Complex Fire included: Big Sur and Carmel Valley communities, Salinas Valley farm land, Highway 1, numerous state parks and camp grounds, private residents and essential steelhead salmon habitat.

Stakeholders

Jurisdiction

Assessment of the burned area fell under the jurisdiction of the US Forest Service and California Forestry and Fire Protection (CalFire). CalFire was the lead agency for the assessment. The policies of both agencies are to provide rapid assessments of the burned areas and suggest best management practices to avoid further damage from erosion and debris flows.

Future Research

Future work should seek to understand the impacts of rain on the burned area. The greatest hazards to the communities of Big Sur is flooding and debris flows. The in stream habitats of threatened steelhead will also be effected by erosion and debris flows. There is little understanding of the direct effects of post-fire erosion on steelhead habitat.
