Pacific Rim Conservation conducts and manages several predator control projects in Hawaii, and has successfully conducted several predator eradications in Hawaii both on offshore islets and from within fenced areas. On most islands throughout the Pacific region, alien terrestrial mammals (rodents, mongoose, mustelids, cats, dogs, and ungulates) pose a serious threat to native biota that did not evolve with mammalian predators and lack natural defenses against these animals. We work with State and Federal agencies and other pest control organizations to ensure that animal welfare guidelines are followed and that the most current, effective, and humane techniques are employed. Methods include live trapping, snap trapping, and poison bait stations. Our staff are certified restricted pesticide applicators.
Predator control to protect the Oahu Elepaio
For 20 years, we have conducted control of alien rodents to reduce nest predation and improve survival of Oahu Elepaio, and monitoring efficacy of the rodent control program, in collaboration with the Hawaii Division of Forestry and Wildlife, the U.S. Army, and the Nature Conservancy of Hawaii. When rats are trapped, twice as many Elepaio pairs successfully raise a chick and fewer females are eaten. For more information on this project and on the Oahu Elepaio, visit www.elepaio.org. For published results of this work, see Report #22
Predator control to protect Red-tailed Tropicbirds
For 11 years, we have conducted control of alien rodents and mongoose to reduce nest predation and improve survival of a small Red-tailed Tropicbird colony on Oahu, and monitoring efficacy of the control program. Results have been highly positive with both the reproductive success and colony growth rate increasing as a result of the work. For published results of this work, see Report #95.
