[See History of NURE HSSR Program for a summary of the entire program.]
The Oak Ridge Gaseous Diffusion Plant occasionally collected samples of plants during orientation phases of the NURE HSSR program. These samples consisted of various species of deciduous trees, coniferous trees, bushes, mosses, and algae. Although these samples were often not discussed in the various reports of studies, the records containing site descriptions and analytical data were included in the accompanying digital data files. Plant records were found associated with the following studies.
At the time of this Open-File release (v. 1.41), the ORGDP plant data have been compiled into a single file and partially reformatted. The current ORGDP Plant Data Format is explained below.
The compiled and partially reformatted data file for ORGDP Plant Studies is available by request from Steven M. Smith (smsmith@usgs.gov).
Explanations are included here only for fields or field values unique to ORGDP Plant Studies. For the explanation of common fields consult the On-Line Manual for USGS-Reformatted NURE HSSR Data Files. After each field name is a format code. A format code of (A1) means that the field is formatted as an Alphanumeric (A) field 1 character wide and a code of (N) means that the field is formatted as a Numeric field.
The number of plants sampled or, in the case of mosses, the number of grabs.

The diameter, in meters, of the tree trunk (1 meter above the ground) from which the botanical sample was taken.
The average height, in meters, of the plants from which the botanical samples were taken.
Analytical methods used to determine element concentrations listed in a record. Data added during the reformatting process based on published reports. Method codes and summary of analytical methods derived from Grimes (1984) and special studies documentation. Only those methods applicable to plant studies are include here. See the On-Line Manual for USGS-Reformatted NURE HSSR Data Files for a list of other methods.
