Pike & San Isabel National Forests Cimarron & Comanche National Grasslands Proposed Stand Exam FSVEG Update

Solicitation Number AG-82BH-S-16-0042 Amendment Number 0001 dated August 26, 2016

Field 22,23,25: Damage. The presence or absence of Dwarf Mistletoe will be checked on all trees. Always record if present regardless of what other damages have been recorded. For all other damages record only those significant damages that are most affecting tree growth and/or longevity. For all trees, a maximum of 3 damages will be recorded. If a tree has no significant damage, record no damages for that tree.

Field 27: User defined. We need to know the density of Old trees in each stand. Contractor shall classify every tree for old tree characteristics as defined in the report RMRS-GTR-110.

The classes will be OLD, MOD(erate), and Y(oung). The general age ranges (at dbh) for these classes are: <140y = Y; 140-190 = MOD; >190 = OLD.

Any tree species can be given an OLD identity. For this Contract an example is ponderosa pine: flattened, misshapen, sparse crown; few but large branches; columnar shaped trunk; pale orange or grey bark, smooth, with small scales; fire scars, dead tops, broken branches, lightning scars, rot, burls, exposed roots; generally remnants are larger in diameter and height than surrounding trees but some may have broken tops. Remnant lodgepole pine can resemble remnant ponderosa pine in crown condition, and bark color and texture. Identifying OLD Douglas-fir is more subtle, yet they can have many of these characteristics and the bark may be thickly furrowed. Old limber pines often have young-looking tops, but the old characteristics show up as large middle and lower branches and/or large dead branches. In this area old fire butt scars almost always indicate OLD, or at least transitional (MODerate) age.

The following items, except as noted, are required to be collected by Contractor for each tree on the plot, for the specified exam level. Detailed information and lists of valid codes for each data field are found in the Common Stand Exam User Guide and Appendices (see Government Furnished Property). Contractor shall be responsible for collecting and filling out the Tree Data Form for all data items that are set to “YES” in the required column.
