lush vegetation, warm temperatures and high humidity not only
welcome human visitors but indiscriminately provide a tropical
paradise for the more than 1,000 alien plants, vertebrates,
and invertebrates that have been accidentally introduced from
all corners of the world over the past 65 years. Some have
become established at the expense of native species, competing
for habitat and nutrient sources.
One species that has garnered much attention recently is the
coqui frog, Eleutherdactylus coqui. Its ability to
quickly adapt to Hawai'i from its native Puerto Rico and reach
unprecedented numbers, the absence of predators, and its noisy
mating behavior have made the coqui frog the target of government
and community eradication and control efforts.
The purpose of this Web site is to provide a comprehensive
resource for biological and control aspects of the coqui frog
invasion in Hawai'i. Here you will find original research
summaries, tips for homeowners, photos, and links to other
Web sites and articles.
