The 2002-2003 John Day Fossil Beds National Monument vertebrate inventory developed species lists and additional information on birds, mammals, and herpetofauna in the John Day Fossil Beds of eastern Oregon. Fish were not included in the vertebrate inventory. Information on this vertebrate class was assembled from recent state survey data. The primary goal of the inventory was to confirm 90% of the species expected to occur in the monument. Additional goals included developing baseline data for monitoring as well as providing the National Park Service and the research community-at-large with new and important information on the biodiversity of the region. Expected species lists were developed from available historic sources and expert opinion. A set of four criteria was used to determine the likelihood of detection in the park. Inventory fieldwork utilized a variety of methods to achieve the primary objective, including visual encounter surveys, point counts, and trapping. Species documentation included the collection of voucher photographs, specimens, digital bat call recordings, and field observation records. Inventory fieldwork included several brief visits to the monument in 2001 and extensive fieldwork was conducted in 2002 and 2003. Information from the 2001-2003 Antone Christmas Bird Counts was included as well as information from the NMBS Wheeler County fall migration counts. Results from a separate University of Idaho bat radio telemetry project conducted in the monument in 2003 are included. Recent vertebrate sightings from monument staff also contributed to the inventory results. The 2002-2003 inventory was productive and brought species confirmation totals to 97% for birds, 90% for mammals, and 89% for amphibians and reptiles.
