Appendix I - Data Dictionary for CoverType

CoverType. The CoverType feature class is updated for new stands created through timber sales as well as naturally occurring landslides, windthrow, and so forth. Units identified in the sale administrator’s monthly report as having been yarded are updated on this layer. Reserve (deferred) areas that fall on the boundary are not mapped as individual polygons with unique stand numbers and on this layer. CoverType displays the “net” treated area within the harvest unit.

RESERVE-AMOUNT * amount reserves left in the unit will be determined by unit of measure to

0-999 valid codes; 1-100 (percent) if using B as UOM; 1-500 (trees/acre) if using T as UOM;

use 999 only if reserves are present in an unknown amount

RESERVE-UOM * Reserve amount Unit of Measure

T B

Trees/acre or % Basal area

*The same unit of measure is used for all sub-units within the harvest area. In order to calculate the percentage reserved within the unit as a whole, the original basal area or trees per acre must be known from stand examination and or timber cruise information. These fields should not be used to determine if TLMP Revision standards and guidelines for goshawk, marten, and so forth, are being achieved. Each polygon sub-unit will have a different reserve amount if reserves vary by sub-unit.
