From 2001 to 2007, point count surveys using distance sampling were conducted on a series of minigrids in the northeastern region of Denali National Park and Preserve, Alaska. The minigrid is the sampling frame and each minigrid consists of 25 sampling points spaced 500-meters apart. Each minigrid is either 10- or 20-km apart. The goals of the quantitative analysis project would be to: (1) analyze the data collected between 2001 and 2007 and provide estimates of densities of songbirds at the local (sampling plot) and ecological (habitat type) scales; (2) assess the precision of the current sampling methodology; and, (3) provide guidance for conducting future point count surveys for assessing the spatial and temporal variation in abundance and distribution of songbirds in the Central Alaska Network (CAKN).
