Among the many threats to the continued existence of the remaining native forests and other native ecosystems of the Hawaiian Islands, the most severe and the most difficult to control are the invasion and replacement by induced species of plants. Because conventional methods of plant management have faild to control this invasion, a multiagency, state and federal program was initiated in 1980 to attempt control through the use of classical biological control: the inutroductian, release, and establishment of the natural enemies of the weeds, including both insects and pathogens. Currently....

An integrated biotic inventory of mangrove areas of Pohnpei, Federated States of Micronesia, was undertaken to determine priority areas for preservation and sustained-yield management. Criteria for the designation of reserve areas included: the presence of threatened or endangered species; rare species or particularly rich biota; undisturbed old-growth communities; the need to maintain intact mangrove to protect biotic resources from excessive wave action or sedimentation; or similarly, to protect cultural and economic resources; areas of high fisheries or forestry productivity; timber...

Natural regeneration is one mechanism by which native mixed-species forests become reestablished on abandoned pasture. This study was done to determine patterns of and requirement for natural regeneration of native species in an open woodland after removal of cattle. Ten 50- by 50-m quadrats were randomly selected within a 16-ha exclosure located at 1,700-m elevation inside the Hakalau Forest National Wildlife Refuge on the island of Hawaii. In 1989 and 1991, data were collected for all regeneration in the quadrats, including species, height, and seedbed type. More than 2,000 individuals...

The 17 papers in the Proceedings of the Session on Tropical Forestry for People of the Pacific cover the topics of the USDA Forest Service's tropical forestry research, forestry research in Asia and the Pacific, management of tropical forests for products and energy; forest and wildlife management, the South Pacific Forestry Development Programme, tropical rainforests of northern Australia, forest resources in New Guinea, management factors affecting forests, forests of East Kalimantan, forest biological diversity, hydrologic effects on forest management, fire management in Central...

The educational poster session provided a way of increasing the ordinarily limited time available for discussion of papers, while simultaneously making it easier to communicate visual materials not well suited to oral presentations. Poster presenters were available for 3 hours to discuss their displays. Poster presentations were divided into two categories: minority issues and management issues. These poster presentations are summarized below. This symposium session was moderated by Tracie Welton, USDA Forest Service, and George Welton, California State University at Northridge.

This study presents preliminary result interviews with people of color working in environmental education and interpretation throughout the United States. The three primary questions asked were these? (1) What path led each individual to a career in environmental education; (2) How does each individual define environmentalism? and (3) What are the primary issues this field must address? Identifying the common life experiences that pulled these individuals toward environmentalism may assist in attracting more people of color to the environmental professions, and may facilitate drawing...

The round table session was designed for interaction between the presenters and other round table participants. Twelve round tables, each capable of holding 10 participants were set up in one room. Presenters for the sessions were encouraged to lead discussions on one of many topics in these areas: a research idea that the presenter was just formulating; an unpublished, preliminary result from a recently completed or in-process study; or the latest management techniques used in a resource area. This session was moderated by Arthur W. Magill, Pacific South-west Research Station, USDA Forest...

Blacks, Whites, Hispanics, and Asians in Illinois attach a high level of significance to outdoor recreation. However, there are important differences in the outdoor recreation participation patterns of these four groups, including the activities participated in and where they participate, that have important implications for recreation resource planning and research.

The Coachella Valley is situated in eastern Riverside County, California, approximately 100 miles east of Los Angeles. During the 1980s it was one of the fastest growing areas in the nation with an annual growth rate of 8.3 percent. As open space diminished, many governing jurisdictions, and environmental and educational organizations began looking for a commitment to open space for future generations. The Santa Rosa Mountains have become the focus of this intense effort by a multiorganizational partnership.

A variety of formal and informal "partnerships" have evolved in the course of planning for the first two of several large-scale, multi-million dollar private sector tourism development projects proposed for the small town of Canmore, adjacent to Banff National Park, Canada. This paper briefly identifies the major impetuses for and the nature of these partnerships which have involved Canmore planners, area residents, environmental groups, developers, and a variety of local and provincial government departments. Drawing on social dilemma theory concepts, the paper notes that both structural...
