The James Reserve was used intensively during 1971-72, with 13,362 man-hours of use recorded. Dr. Rodoipho Ruibal, Professor of Zoology, UCR, used this Reserve as the site for his graduate field class, Biology 272 (Field Course in Evolutionary Biology). Weekly measurements were made on the Reserve throughout the Spring Quarter. A combined report, a copy of which has been sent to the President's office, was completed at the end of the quarter. Timothy W. Robertson, an undergraduate 11CR student, completed a plant survey of the James Reserve under the direction of Dr. Frank C. Vasek, Professor of Botany at UCR. A copy of this report also has been sent to the President's office. Dr. Timothy Prout, Professor of Zoology at UCR, and his graduate students began, and are continuing on a long-term basis, a study of the population genetics and ecology of the fruit fly Drosophila pseudoobscura at this Reserve.

The number of applications to use the James Reserve has increased during the past year. The number of man-days the reserve was used, and the organizations or institutions involved, are given in Table 1. Researchers, teachers or students from 6 University of California campuses, 14 other California organizations or institutions, 4 other states, and 5 foreign countries participated in activities at the reserve. David Hagstrom completed his investigation of spiders this year, and is preparing the data for his Ph.D. dissertation. The long term studies of Dr. Jean Pierre Simon on grasses and Dr. Charles Fleschner on pine insects are continuing. No new long term investigations were initiated this year.
