>> quijano: more than two dozen large fires are burning out of control in the west. that's in addition to nearly a hundred smaller fires. in central washington a fire that broke out this weekend is threatening homes and officials have ordered evacuations. each year wildfires seem to get worse despite the heroic efforts of firefighters. carter evans visited a lab where they are studying a new approach.

conditions fires thin out forests but by constantly putting them out, more unburned brush is left for the next fire. finny says firefighters should be intentionally setting more so called prescribed fires to burn off excess vegetation or simply let some natural fires burn. in a statement to cbs news, the forest service says it agreed that managed and prescribed fires are important tools but our capacity to complete this work is restricted by the budget, which is allocated by the agency also says there are liability issues with state and local governments as more developers push to build homes closer to fire-prone areas. >> reporter: fire is inevitable. if we convince ourselves that it is not, essentially we have a repeat every year of the same situation. >> reporter: for now scientists hope that by setting these controlled fires in the lab, they'll better understand how to manage them in the forest. carter evans, cbs news,
