Permanent 1 m^2 vegetation plots were established near each of the
88 Saddle grid stakes in 1989 by Marilyn Walker, who led the
sampling effort until 1997. To estimate plant canopy cover, point
quadrat measurements have been made at irregular intervals from 1989
to the present (1989, 1990, 1995, 1997, 2006, 2008 and yearly from
2010 onward). The point-quadrat technique used for sampling was
described in Spasojevic et al. (2013) and Auerbach (1992). Auerbach, N. 1992. Effects of road and dust disturbance in
minerotrophic and acidic tundra ecosystems, northern Alaska.
