In 2011, fires in Bastrop County, Texas, were the most destructive 

wildfires in Texas history.  

The fire spread through the Loblolly pine trees and scorched 

nearly 5,700 acresof Bastrop State Park.  

The majority of the Houston Toad’s habitat was lost, and 

the Lost Pines Forest was heavily affected.  

A food web of the Bastrop State Park environment is shown below.

The loss of habitat for the Houston Toad most likely affected 

the food web by -

• causing a decrease in the number 

  of wildflowers

• causing an increase in the number 

  of insects

• causing a decrease in the number 

  of armadillos

• causing an increase in the number 

  of opossums
