Back in 1995, the California Department of Fish and Game released a report on burrowing owls that described how to survey for them and steps that could be taken to mitigate loss of habitat. Yet, the numbers of burrowing owls in California have continued to decline.
A new, 36-page report goes into more detail and incorporates research that has been done since the 1995 report. It includes suggested survey protocols, and buffers for various times of the year.
