Data was collected on the Yukon Kuskokwim Delta, Alaska, USA from 1991-2016. Data was collected with aerial photography and videography along transects. Photos captured approximately 69m squared of ground space and were spaced at least 200m from one another. 10x10 (1991-1999) or 12x15 (1993-2016) overlaid photographs and the number of points on the grid primarily occupied by various habitat types was recorded. In program R, data was cleaned to identify the number of points per grid occupied by Carex subspathacea grazing lawns. Column Headers: SIZE is the number of points overlaid as a grid on a photo; SUB is the number of points in a grid occupied primarily by Carex subspathacea; YEAR is the year the sample was taken.
