STUDIES IN THE LIFE HISTORY OF THE 'ALALA IN CAPTIVITY* Barbara Lee Division of Fish and Game State Department of Land & Natural Resources Honolulu, Hawaii This illustrated report describes observations on behavior of hand-reared 'Alala (Corvus tropicus) maintained as captive breeding stock at the State of Hawaii's Endangered Species Project, Pohakuloa, Hawai' i. The development of husbandry techniques and the problems and experiences related to establishing and maintaining a breeding population of 'Alala in captivity will be briefly discussed as well as the objective study of social, instinctive, and reproductive activities of the only six 'Alala in captivity. * Abstract
HUMAN PERCEPTION OF THE HAWAIIAN ENDANGERED SPECIES: A PRELIMINARY REPORT ON A THREE-YEAR RANDOM SURVEY Mark David Merlin Department of General Science University of Hawaii at Manoa Honolulu, Hawaii 96822 INTRODUCTION The rare and endangered species of Hawai'i represent one of the major problems facing those interested in preserving the exceptional natural heritage of the Hawaiian archipelago. It is well known that the Hawaiian Islands have a diverse and unique native biota. Most regretfully, a relatively large number of endemic species have already become extinct within historic times and several more are on the verge of disappearing forever. There are a number of reasons for the extraordinary demise of so many of the native Hawaiian species. Exploitative land use, the impact of large feral herbivore populations, the introduction of aggressive weed species, fires, predatory and patho- genic organisms, and general habitat destruction have all taken their toll on the unique and vulnerable endemic species of Hawai'i. The impact of these problems has become increasingly acute in recent years. OBJECTIVES The basic assumption underlying the research discussed below is that a general consensus regarding the importance of the rare and endangered species is lacking. In order to determine citizen attitudes relevant to this issue, an ongoing research effort was initiated in 1976 to survey human perception of the problem. The goal of this project has been two-fold in nature: on one hand, there has been an attempt to quantify perception of the real or potential economic, scientific, aesthetic, ecological, and biological value of the rare and endangered species; on the other hand, it has also been the aim of this research to stimulate more study into the problem so that an objective measurement of the public's attitudes can become known. In other words, this is basically a pioneering effort to monitor popular feelings about an issue of growing concern and urgency. Furthermore, it has been hoped that the survey process will in some way elevate public awareness of the problems so that educated decisions af- fecting the future of the native Hawaiian plants, animals, and habitats can be made.
