| Variable | Description |
|---|---|
| Plot IDz | Unique identifier |
| Plot addressy | |
| Date and crew | |
| Photo number | Used to help identify plot |
| Measurement unitsz | Units for all measurement in the plot; metric (m/cm) or English (ft/in) |
| Reference objectsy | At least two objects that will assist in locating plot center for future plot remeasurements |
| Distance to reference objecty | Distance from plot center to each reference object (ft or m) |
| Direction to objecty | Direction from plot center to each reference object (degrees) |
| Tree measurement point (TMP)y | If plot center falls on a building or other surface (such as a highway) where plot center cannot be accessed, the plot is not moved; all distances and directions to trees are measured and recorded from a recorded fixed point (e.g., building corner) referred to as the TMP |

| Land usez | As determined by crew in the field from a standard list of land uses |
| Percent inz | Proportion of the plot in each land use to nearest 1% |
| Tree coverz | Percent of plot area covered by tree canopies estimated to nearest 5% |
| Shrub coverz | Percent of plot area covered by shrub canopies estimated to nearest 5% |
| Plantable space | Percent of plot area that is plantable for trees (i.e., plantable soils space not filled with tree canopies) and tree planting would not be restricted as a result of land use (footpath, baseball field, and so on); to nearest 5% |
