Biological surveys and Monitoring
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
- 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.
