The island of New Guinea has a high diversity of species and a high level of endemism, containing more than 5 percent of earth’s biodiversity in just over one half of a percent of the land on the earth. New Guinea supports the largest area of mature tropical moist forest in the Asia/Pacific region. Papua New Guinea consists of the eastern part of the island of New Guinea, plus the islands of the Bismarck Archipelago, Buka, and Bougainville. There are between fifteen thousand and twenty thousand species of vascular plants in Papua New Guinea, with at least two thousand species of trees. The most important challenge for Papua New Guinea is the protection of biological diversity against the pressures resulting from global climate change, inappropriate destructive conversion of natural communities, unsustainable exploitation of forests, national economic development and societal demands, including a fair sharing of the nation’s wealth, and law and order issues. There are very few resources available to natural resource managers, environmental scientists, nongovernment agencies, and various extractive industries, most importantly, the timber industry that will assist in the identification of major tree species within Papua New Guinea. It is hoped that the publication of these three volumes will enable those who are responsible for natural resource management to improve their knowledge of the trees in these forests so that they can fully appreciate the richness of these biologically diverse forests. The forests of Papua New Guinea need to be managed sensitively and sustainably based on advanced evidence-based knowledge. The Trees of Papua New Guinea publication provides a comprehensive treatment of 668 species of trees (Volume 1: 257 species; Vol. 2: 246 species; Vol. 3: 165 species) that will assist in the identification of the trees of Papua New Guinea.

Traditional medicine, including the knowledge, skills and practices of holistic health care, exists in all cultures. It is based on indigenous theories, beliefs and experiences, and is widely accepted for its role in health maintenance and the treatment of disease. Medicinal plants are the main ingredients of local medicines, but rapid urbanization is leading to the loss of many important plants and knowledge of their use. To help preserve this knowledge and recognize the importance of medicinal plants to health care systems, the WHO Regional Office for the Western Pacific has published a series of books on medicinal plants in China, the Republic of Korea, Viet Nam and the South Pacific. Medicinal Plants in Papua New Guineais the fifth in this series. This book covers only a small proportion of the immense knowledge on traditional medicine, the plant species from which they are derived, the diseases they can treat and the parts of the plants to be used. The diverse cultures, languages and traditional practices of Papua New Guinea made this a particularly challenging project. But we believe the information and accompanying references can provide useful information for scientists, doctors and other users.

This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.
