Scars as an Indicator of Fire Frequency in the San Bernardino Mountains, California
Abstract:Fire frequencies in the ponderosa and Jeffrey pine types prior to and after 1905, the year of initiation of fire control programs in the San Bernardino Mountains, California, were determined from ring counts between scars on wood sections removed firm living trees. Ponderosa pine showed a frequency of 10 years prior to 1905, when organized protection began, and 22 years thereafter. The respective figures for Jeffrey pine were 12 and 29 years. Differences in the intervals between ponderosa and Jeffrey pine may be due to climatic variation. The method used to remove the wood sections has several advantages that may favor application elsewhere.
