Crazy Ant Strike Team (C.A.S.T.)

The current Crazy Ant Strike Team biological crew of four volunteer technicians and one crew leader are living on uninhabited Johnston Atoll.

We are currently searching for CAST 18!

For more information please visit the position description

Previously, millions of Yellow Crazy Ants had completely displaced ground nesting bird populations and were impacting the largest nesting red-tailed tropic bird colony in the world. Building upon the eradication efforts of CAST crews before them, this crew carries forward a goal of complete eradication of Yellow Crazy Ants that have been reduced, over back-to-back strike team efforts, by over 90%.

Although the remote location and isolation of Johnston Atoll and other Pacific island refuges make it virtually impossible for the general public to visit, the U.S. Fish and Wildlife Service is hoping that advances in technology can one day bring to you the sites and sounds of this unique wildlife recovery site through internet based services.

Support your National Wildlife Refuges by joining organizations such as the National Wildlife Refuge Association that actively supports and advocates for the National Wildlife Refuge System.  Within the remote areas of the Pacific, Friends of Midway Atoll National Wildlife Refuge and Friends of Hawaiian Islands National Wildlife Refuge are non-profit organizations that help support millions of transitory wildlife and restoration projects on both islands and the ocean habitats in the Northwestern Hawaiian Islands.


Restricted access to the refuge is managed through the issuance of a Special Use Permit when the activity is deemed appropriate with the current research and resource management needs of the refuge.
