Hematologic values for 99 tule elk (Cervus elaphus nannodes) from California (USA) are presented. These were obtained from individuals from three captures at Tomales Point (Point Reyes National Seashore, California) from 1997-98. Differences between capture groups were assessed. Greatest differences were detected between yearling bulls and cows in December 1998 which may be a reflection of age and reproductive status.
