This is the second set of old-field photographs made with a 35mm lens rather than a 50mm one. (A 35mm lens on a digital camera produces approximately the same field of view as a 50mm lens on a film camera.)
Plot D was first dominated by white sweet clover with patches of wild radish. By May white sweet clover was mostly gone and ragweed was dominant. By mid June patches of lamb's-quarters were taller than the ragweed, but by the time these pictures were taken the ragweed had equaled or overtopped the lamb's-quarters and the plot looked like a nearly pure stand of ragweed.
In Plot A, the saltbush saplings that were prominant in the foreground of the June 2007 photograph are absent because the scattered saltbush in the northern two-thirds of the plot was cut, whereas the thick stand of saltbush in the southern one-third was left in tact. [This management was approved by NAAC as appropriate for a 40-year plot judged to owe its abundant saltbush to the spoil from the SEEP basin that was spread on it.]
