In the 2017 mountain -wide survey, no palila were detected along the southeast and eastern slopes of <br />Mauna Kea, where they have been detected historically. There were two detections on the north slope <br />of Mauna Kea where wild birds were translocated (1997-1998, 2004-2006) and captive -reared birds <br />were released (2003-2005, 2009; Banko and Farmer 2014). This area is adjacent to and upslope of the <br />Pu'u Mali mitigation area where former pasture land has been taken out of grazing and reforestation of <br />native trees has begun. There were also pallia detected below the core area on the southwest slope <br />(lower stations on transects 124 and 125), another area where former pasture lands are subject to a re- <br />forestation project. Despite these hopeful signs that reforestation has begun to rehabilitate former <br />pasture land into palila habitat, palila range has been relatively constant across the annual surveys and is <br />only about 5% of its historical extent (Figure 1 inset; Banko et al. 2013). <br />ACKNOWLEDGEMENTS <br />Funding for annual paliia surveys since 1998 was provided by Federal Highway Administration, U.S. Army <br />Garrison Hawai'i, Hawaii Division of Forestry and Wildlife, U.S. Fish and Wildlife Service, American Bird <br />Conservancy, and the U.S. Geological Survey Wildlife Program. Funding for analyses of the data since <br />2012 was provided by the Hawaii Division of Forestry and Wildlife. We are grateful to the many agency <br />staff and volunteers who helped collect survey data and to C. Farmer and S. Hess for reviews of an early <br />draft. Editorial assistance was provided by 1.
