The 1994 debut project of PCS was the Biib Environmental Awareness Project, an intensive campaign supported by the RARE Center for Tropical Conservation. The one-year campaign focused on the Biib, Palau’s endemic fruit dove and candidate for national bird. Using puppet shows, posters, billboards, music videos, and other media, the campaign highlighted the values of the biib and the environment on which the bird depends. The campaign touched virtually every schoolchild in Palau and measurably increased the public’s awareness of environmental issues and values.

In 1997, with support from the South Pacific Regional Environment Programme and the British government, PCS undertook a similar and successful campaign focused on the endangered dugong.

In collaboration with the University of Guam and the government of Palau with support from the Japan Fund for Global Environment, PCS coordinated the Coral Reef Monitoring Project with the purpose of documenting baseline levels of sedimentation on Palau’s reefs so that future impacts of physical development can be detected and mitigated. The Nature Conservancy and the Forum Fisheries Agency supported the Grouper Aggregation Monitoring Project led by PCS collaborator Dr. Robert Johannes. Under contract from the government of Palau, PCS collaborated with scientists from UCLA and the Australian Institute of Marine Science to conduct a Study of Water Circulation in Malakal Harbor in order to assess the fate and effects of sewage effluent entering Palau’s main harbor.

The Inshore Sportfishing Development Project, supported by the U.S. government, was a collaborative project between PCS, The Nature Conservancy, and the Palau government. The aim of the project was to conserve and make the best use of the diversity and abundance of Palau’s reef fishes by developing a community-based sportfishing industry.

With support from the Keidanren Nature Conservation Fund of Japan and the South Pacific Regional Environment Programme, PCS has assisted Koror and Peleliu States in the management of their marine resources in the world-renowned Rock Islands. Projects included preparation of a plan for the Management of Ngerumekaol, an important fish spawning aggregation site, and preparation of the Peleliu State Conservation Strategy.

PCS undertook the Ngemelis Tourism Management Project, with the aim of improving management of Palau’s diving industry. Assistance from the Wallis Foundation made it possible for PCS to also examine the impacts of the booming Taiwanese tourism and produced the Palau’s Taiwanese Tourism Industry: Assessment of Issues and Suggestions for the Future Report. With support from the World Resources Institute and in collaboration with research partners in Indonesia, the Philippines, and Japan, PCS undertook a Benefits Analysis of Palau’s Tuna Fisheries. The aim was to provide the information necessary to make decisions about alternative uses of Palau’s valuable offshore fisheries resources.

PCS was instrumental in the development of the famous Jellyfish Lake as a tourist destination. Working in partnership with Koror State and RARE Center for Tropical Conservation, PCS installed a nature trail with educational signboards, floating docks both inside and outside the lake, and provided composting toilets. Jellyfish Lake has since become one of Palau’s most popular tourist destinations.

Funding from the Packard Foundation enabled PCS to assist several of Palau’s state governments in the establishment and management of conservation areas in key marine and terrestrial areas, including remote Ngeruangel atoll in Kayangel, Ngemelis Island in Koror, Ngemai reef in Ngiwal, and Ngardok Lake and watershed in Melekeok. The Packard Foundation also funded PCS’ assessment of Palau’s reef fish fishery. With support of the MacArthur Foundation, PCS began assisting several communities with conservation area management and land use planning.

All of PCS’ education, research, and management activities have the ultimate goal of contributing towards sustainable development policies at the national and state levels. The timely provision of relevant information on the state of Palau’s natural resources to Palau’s local and national leaders has always been a priority.
