30 March 2007 (Started February 1997)
Re-start in progress:
Trees were cut 10 January 2007 (as shown in this photo).
Plot was later disked 14 June, 5 September, and 19 December 2007.
This photograph was made with a 50mm lens. The later ones were made with a 35mm lens. |

29 January 2008 (Re-started December 2007)
The partially burned logs at the right edge of the Plot D picture were removed a few days after the picture was made.
This is the first 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.)

(Re-started December 2007) By late fall, Plot D was almost a pure stand of 6 to 7-foor tall ragweed. The dead stalks of these plants now dominate the plot.
