"Controlling the coqui"

Featured Update
 
coqui frog 
 

 

The coqui frog, Eleutherodactylus coqui, threatens the stability of
Hawaii's native forest ecosystems. High densities of the coqui frog have become a serious noise nuisance in residential and tourist areas and are also decreasing property values. 

 

Vendor and public concern over purchasing infested nursery material is impacting the floriculture and nursery products industry as coqui are accidentally transported.

Hans Sin has worked as the coqui Frog Coordinator for the Department of Land and Natural Resources on the Big Island since October 16, 2006. He earned his MS degree in Wildlife Biology at Utah State University by working on the ecosystem effects of coqui frogs in lowland rain forests on the Big Island. In addition to coordinating control efforts for DLNR, working to provide a multi-agency coqui database to track progress and provide assistance and technical support, Hans helps keep the statewide coqui plan updated. 

Aloha!
 

For the second edition of the Hawaii Invasive Species Council eNews, the coqui frog is our featured creature. Current estimates indicate there are more than 8,000 coqui-infested acres on the Big Island with much smaller and, fortunately, eradicable populations on Maui, Oahu and Kauai. The work done by residents, agencies and researchers to control this species alone will cost over $4,000,000 this year. Multiple coqui Frog Working Groups and neighborhood Frog Squads work to limit the spread and impacts of this invasive species. To get a picture of these efforts, please take a look at "Hawaii's coqui Frog Research, Management and Education Plan."
