Purpose

Species management, particularly the conservation of rare species, is costly requiring funding, personnel and time that are increasingly limited. Moreover, management of rare species requires precise measures of population abundance and trend to assess the effectiveness of management actions and species conservation. This dataset was collected to assess population status and evaluate the trend of Hawaii Akepa, and forest birds in general, within the Hakalau Forest National Wildlife Refuge.
