Monitoring Effort Update-HY2014
• Tern Island: Loss of nesting seabirds and infrastructure on Tern Island due to extreme weather event in December 2012. Field station still closed for the foreseeable future.
• Laysan Island: Nest count and demographic plots not conducted due to medical evacuation of crew from the island in October 2012. Field camp still closed due to budget constraints until the foreseeable future.
• Midway Atoll: Full nest count conducted and demographic plots monitored in HY 2014.
