Annual bird surveys of the internal control plots of the Silvicultural Systems Trial, 1998-2015

Dataset contains 5-minute point-counts of bird species seen or heard at sample stations on fixed routes through the two internal control plots of the Silvicultural Systems Trial (WR008J and WR008K). Prior to 2006 surveys were limited to WR008J on two occasions (1998-9 and 2004-5) from 2006-7 onwards annual surveys were done in both control plots. Each annual survey comprises 5-8 spring-summer visits. See Lefore and Grove (2009) Forest Ecology and Management, 258: 460-471 for details.
