Volunteer Positions on the
9th Crazy Ant Strike Team Expedition
Johnston Atoll National Wildlife Refuge

The U.S. Fish and Wildlife Service is seeking 4 volunteers beginning early 
November 2014 for up to 8 months to join the 9th Crazy Ant Strike Team (CAST 
IX) Expedition to Johnston Atoll National Wildlife Refuge (NWR).  Johnston 
Atoll is located in the central Pacific Ocean, 717 nautical miles west-
southwest of Honolulu.  The refuge is managed for 14 species of breeding 
seabirds and 5 species of wintering shorebirds in addition to its diverse 
coral reef and marine organism assemblages, including the threatened green 
sea turtle.  The atoll contains four small islands (696 acres), which 
constitute the only land area in over 750,000 square miles of ocean.  The 
emergent land associated with this refuge provides critical, rat-free 
habitat for central Pacific seabird populations and its coral reef ecosystem 
is an important marine resource.  The refuge is uninhabited except for the 5 
member crew. Volunteers will have the opportunity to live in this remote 
setting surrounded by birds and sea life.  

In January 2010, an infestation of Yellow Crazy Ants (YCA), Anoplolepis 
gracilipes, was found affecting approximately 130 acres of the 630-acre 
Johnston Island.  Yellow Crazy Ants, named because of their manic behavior 
when disturbed, have wreaked havoc on ecosystems and bird habitats in other 
parts of the world; therefore the presence of this infestation is cause for 
great concern.  Local impacts to wildlife already observed on Johnston 
Island include the apparent desertion of the entire affected area by ground 
nesting birds (Red-tailed Tropicbird and Wedge-tailed Shearwater) that 
previously occupied those areas and a possible reduction in density and 
numbers of tree-nesting bird species (Red-footed Booby and White Tern) 
inside the area colonized by YCA.  The potential for even greater impacts to 
the terrestrial ecosystem at Johnston Atoll is substantial if the 
infestation of YCA is left unchecked.   

Efforts have been ongoing since August 2010; YCA numbers have been reduced 
by 99% and the seabirds have begun to return. Duties performed by CAST IX  
will include: 1) in Honolulu, Hawai’i, packing and preparing gear, food, and 
all items necessary for the camp; and 2) on Johnston Island, applying 
pesticides, biological monitoring of ants, coral reef, and bird communities, 
and camp maintenance.  CAST IX will consist of 4 volunteers and a crew 
leader. 

Volunteers will be expected to work at least 48 hours/week, 6 days/week.  
However, this does not necessarily mean 8-5 M-F as some projects will 
necessitate working evenings or consecutive days.  Primary responsibilities 
will include: 
•       Ant bait application and monitoring
•       Entomological surveys/ bioassays
•       Seabird, shorebird, and sea turtle surveys
•       Data collection and management 
•       Weekly and summary reporting
•       Camp establishment/disestablishment
•       Camp maintenance and chores 

It is imperative that candidates consider that Johnston is a remote site 
where all but emergency access is by ship, which takes 3-5 days to transit 
from Honolulu.  No re-supply or ship visits during the 6-month camp are 
anticipated.   On the island, transportation will primarily be by foot or 
bicycle with 1-mile daily commutes to the work site.  Living conditions are 
primitive and consist of 12’ x 14’ x 6’ personal sleeping tents while a 
bunker is used for communal/food storage/kitchen and office areas.  Weather 
conditions can be harsh with strong winds, tropical storms, and hot sun.  
Bathing and washing is done in the ocean.  Communication with the island has 
proven to be reliable but is limited to slow internet access.  However, this 
internet access cannot be guaranteed and team members must be prepared in 
case communications become limited to text only e-mail with no internet 
browsing capability. Direct medical attention is at minimum 1-3 days away.  
Safety in this remote setting is of primary concern and all individuals are 
expected to work together as a team to maintain good communication at all 
times.
 
Requirements:  Must be willing and able to work 48 hours per week.  Must be 
physically fit and able to walk 10 miles a day, lift and carry 70 lbs, ride 
a bicycle, swim, and be able to perform repetitive stooping and bending 
motions.  Must be able to perform all duties in various weather conditions 
including high heat and humidity, strong winds, and rain. Qualified 
applicants must possess a valid passport that will not expire before August 
2015.  All CAST members must follow all pesticide and safety protocols.  

Prior experience in the following is preferred: camping, invasive species 
control, shorebird and seabird identification and monitoring, entomological 
surveying, familiarity with GIS tools and software, data management, 
pesticide application and possession of a valid U.S. driver’s license. 

The U.S. Fish and Wildlife Service will provide: airfare to and from 
Honolulu, housing and a modest food stipend while in Honolulu, 
transportation between Honolulu and Johnston, island quarantine clothes, and 
food and housing on Johnston.  The Honolulu stipend will not be paid up 
front so volunteers will need to have sufficient finances to provide for 
their own food for the preparation period in Honolulu.

Applications will be evaluated as they arrive. Interviews will begin mid-
September 2014.
