PREDATOR CONTROL

Small, non-native vertebrate predators threaten native Hawaiian species and ecosystems by eating native plants, birds, snails, and insects. Predators include mice, rats, mongoose, feral cats, game birds and barn owls. 

The control of any of these species is regulated by state and federal laws that address non-target concerns and animal welfare. In addition to the technical information necessary for adopting any of these tools, it is crucial to be familiar with the regulations informing the legality of their use.

IACUC Guidelines

IACUC (Institutional Animal Care and Use Committee) policies were designed for ethical treatment of animals in research settings. Many conservation operations in Hawaii are funded and administered through the University of Hawaii, which must comply with these policies. Here's an overview of IACUC policies. [In the future can include "what to do about IACUC"]
