Bastrop County Complex Fire

The Bastrop County Complex fire was a conflagration that engulfed parts of Bastrop County, Texas, in September and October 2011. The wildfire was the costliest and most destructive wildfire in Texas history and among the costliest in U.S. history, destroying 1,696 structures and causing an estimated $350 million in insured property damage. An exceptional drought, accompanied by record-high temperatures, affected Texas for much of 2011. Vegetation consequently became severely parched throughout the state, and over the year an unprecedented amount of land in the state was burned by numerous wildfires. In early September 2011, the presence of Tropical Storm Lee to the east produced strong northerly winds over the state, exacerbating the preexisting dry weather to produce critical fire conditions. On the afternoon of September 4, 2011, three separate fires ignited in the wildland–urban interface east of Bastrop, Texas, after strong winds caused by the nearby tropical storm snapped trees onto power lines. Within 48 hours, the fires merged into one blaze that quickly consumed parts of Bastrop State Park and parts of the Lost Pines Forest, as well as homes in nearby subdivisions. Most of the conflagration's spread and destruction occurred within a week of ignition, as the forward advance of the wildfire mostly stopped after September 7. The wildfire was largely contained in September, though the firebreak was briefly breached in early October. On October 10, the Bastrop County Complex was declared controlled, and the fire was declared extinguished on October 29 after 55 days of burning within the fire perimeter.

Two people were killed by the wildfire, and another twelve people were injured. The fire perimeter encircled an area spanning at least 32,000 acres (12,950 hectares). Homes were destroyed in ten subdivisions, of which Circle-D County Acres and Tahitian Village sustained the most significant property damage. The wildfire destroyed more homes than any single fire in Texas history by nearly a factor of ten. Around 96 percent of Bastrop State Park was scorched by the wildfire. Roughly 1.5 million trees across 16,200 acres (6,600 hectares) of forest were either killed directly by the fire or fatally damaged. Despite the severe habitat loss, populations of local herpetofauna were not significantly affected by the fire, though extensive soil erosion was enabled by the loss of groundcover.
