Book Description
Ohia forest decline-its severity and rate of spread-was studied by aerial photographic techniques on a 197,000-acre (80,000-ha) portion of the island of Hawaii. In 1954, only 300 acres (121 ha) showed signs of severe decline; by 1972, the acreage of severely affected forest had increased to 85,200 acres (34,480 ha). Rate of decline and current severity were related to mean annual precipitation and to elevation. The epidemic is continuing. Some forests on other Hawaiian islands also display decline symptoms.

Book Description
Hawaii’s forest bird community is the most insular and most endangered in the world and serves as a case study for threatened species globally. Ten have disappeared in the past thirty years, nine are critically endangered, and even common species are currently in decline. Thane K. Pratt, his coeditors, and collaborators, all leaders in their field, describe the research and conservation efforts over the past thirty years to save Hawaii’s forest birds. They also offer the most comprehensive look at the reasons for these extinctions and attempts to overcome them in the future. Among the topics covered in this book are trends in bird populations, environmental and genetic factors limiting population size, avian diseases, predators, and competing alien bird species. Color plates by award-winning local photographer Jack Jeffrey illustrate all living species discussed or described.
