Authorship of the quotation appearing at the bottom of page 5 of the February AIBS Bulletin was incorrectly stated. The statement should have been attributed to Dr. Daniel Mazia, Department of Zoology, University of California, Berkeley. Dr. C. P. Swanson, author of the article “Conservation and Renewable Natural Resources” which appeared in the February Bulletin, was a consultant to the NAS-NRC Division of Biology and Agriculture. He is not chairman of the NAS-NRC “Conservation Committee.” Such a committee does not exist.
