Study Plan for A Field Evaluation of the Primary Hazards to Granivorus Birds from the Use of Zinc Phosphide Ground Squirrel Bait and Baiting Techniques, n.d.

Series II includes three boxes of records related to research conducted by staff at the Fresno Field Station. Much of the research in this collection was carried out at the San Joaquin Experimental Range north of Fresno. Records in Series II include work plans, progress reports, correspondence, bioassay data, and research records pertaining to studies on the potential hazards of field-use rodenticides such as zinc phosphide, strychnine, and compound 1080 to non-target wildlife on rangeland. Also included is research on the economic impact of native rodents on crop and rangeland production in California, including damage to vegetation and irrigation structures. Research on the San Joaquin Kit Fox is included in Series II as well.
