Methods/Experimental Design: Photographs were taken of 12 rectangular frames (dimensions 1.67 x 1.25) designated for repeated sampling within the window of a minirhizotron boxes. These photographic images were digitally analyzed to determine the length of root segments growing within these frames against the window.
Sampling Frequency: Approximately bimonthly
Data Columns: Year - Year
Month - Month
Day - Day
Site - Site number (see Locations, Described above, and Davis et al 2004 below)
Box - Box number
Frame - Frame number
Root_ID - Root identification number
Type - Coded value; (1, 2 - White, 3 - Brown, 4 - Missing, 5 - Unknown, 6 - Placeholder for dates prior to first observation)
RL - Root length; Meter of fine roots per square meter (m/m^2)
