Kauai Bird Surveys from 1981 to 2012 (12 species)

Bird surveys were conducted in 1981, 1989, 1994, 2000, 2005, 2007, 2008, and 2012. From these data we calculated species-specific density and abundance estimates. We conducted separate trends assessments for the Interior (long [1981-2012] and short [2000-2012]) and the Exterior (surveyed 2000-2012) portions of the Alakai Plateau, and using abundance estimates for native species from 2000-2012, we fit a linear and exponential growth model to the population numbers of each species to evaluate time to extinction.
