Biological surveys, Monitoring, and Management
Pacific Rim Conservation undertakes a variety of biological surveys and monitoring for a wide range of clients throughout Hawaii and the Pacific region. We use scientifically recognized methods to measure presence, abundance, and status of bird, bat, plant, and pest populations. Techniques include transects, point counts, and other distance-based methods, mist-netting and banding, mark-recapture analysis, spot-mapping, nest searching and monitoring, geolocation, and GIS. Use of recognized monitoring procedures helps ensure accuracy and consistency and facilitates comparison among projects. When possible, results from biological surveys are submitted for publication in peer-reviewed scientific journals with clients as co-authors.
Survey and monitoring projects
- For the last three years, Pacific Rim Conservation has joined forces with the U.S. Navy and the U.S. Fish and Wildlife Service to help find foster parents for Laysan Albatross eggs that would otherwise be destroyed. Approximately 75 albatross pairs attempt to breed each year at the Pacific Missile Range Facility (PMRF) on Kauai, but because this creates a collision hazard for military aircraft (flying albatrosses can ground planes), the eggs are removed. The eggs are placed in an incubator, and in mid-December, albatross nests at Kilauea Point National Wildlife Refuge and nearby private lands are visited to determine if their eggs are fertile. If albatross on the refuge are incubating inviable eggs, they are given a 'foster egg' from PMRF so that those birds still have a chance at survival.

- Pacific Rim Conservation is collaborating with the US Air Force and Chugach Support Services to conduct monitoring of seabirds, shorebirds, waterbirds, alien rats, and invasive plants on Wake Atoll. We are hopeful that this monitoring will help serve as baseline data for comparison after rats are eradicated.

- Island-wide surveys and long-term monitoring of
Oahu Elepaio populations to evaluate effects of predator control and mosquito-borne diseases, including estimation of annual survival, nest monitoring, and calculating population growth, in collaboration with the Hawaii Division of Forestry and Wildlife, the U.S. Army, and the Nature Conservancy of Hawaii.
