Peters RF, Lusk EE, California Department of Public Health. 1968. To: Boyer RH. Re: Summary of 1967 Plague Surveillance Activities Lassen Volcanic National Park
To the Superintendent of Lassen National Park, from Cal Dept of Health and Welfare Bureau of Vector Control Senior Vector Control Specialist. During the survey period of March to October, 1967, there were a total of 882 trap nights and 138 specimens caught. Visual observations of the park indicate that there was a population decline most likely caused by a die-off following the 1966 survey. Ectoparasite pools were negative. The primary species involved with the plague epizootic was suspected to be the woodrat, later involving the chipmunk and the golden-mantled ground squirrel.
