Belt transects along 2 consecutively-placed, 25m transect lines were surveyed as part of Rapid Ecological Assessments conducted at 3 sites at Laysan Island in the Northwestern Hawaiian Islands in September, 2004 from the NOAA vessel Hi'ialakai (HII04-01). Raw survey data included species presence and relative abundance, colony counts and size classes, and visual estimation of percent cover. Either 0.5m or 1m on each side of the transect lines were included in the belt (for a total of 50m2 or 100m2 per site), depending on colony density.
