Combines the Caribou and Targhee National Forests’ supplements to
reflect the consolidation of the two forests. No direction changes were
made; only the forest name is updated.

CHAPTER 8 – REFORESTATION SUPERVISION, INSPECTION, EXAMINATION, AND
CERTIFICATION
8.35 - Types of Reforestation Stand Examinations.
Caribou-Targhee Reforestation Stocking Survey Objectives and Standards (Proposed). Type 2
stocking examination will be used to determine stocking of both artificially and naturally
regenerated trees in plantations. A fixed plot (variable sized) grid system (variable grid size) will
be used in all third, fourth, and fifth year stocking examinations. Exceptions will be very rare.
The exceptions would include those uniformly regenerated areas that obviously have highly
visible stocking (5,000 trees/ac., three feet in height +). The purpose of these supplemental
objectives and standards is to make these examinations accurate, cost effective and to predict
next treatment (stocking survey, replant, etc.). Objectives and standards for Type 2 exams can
be separated into two categories.
I. Third Year Stocking Examinations. These will include third year exams for natural
regeneration. Timing of examination will occur during the last half of the third full field season
following year of scarification for natural regeneration or immediately following overstory
removal. If low survival from staked rows for planted trees is detected by Type 3 exams and the
examiner suspects the staked results are not indicative of actual stocking, a Type 2 exam should
be conducted.
A. Objectives
1. Determine percent stocking of regenerated area (total satisfactorily stocked plots
divide total plots taken).
2. Determine location of stocked, nonstocked, and unstockable areas.
3. Determine stocking of area in terms of estimated number of trees per acre by tree
species.
B. Standards
1. Show locations of plot centers on map of unit.
2. In naturally regenerated areas, record estimated number of trees on plot. Do not
record any tree characteristics other than species.
3. In planted areas, record planted trees by species and height. For other trees on plot,
estimate number of trees by species and height class.
4. Determine number of plots per acre and plot size based on the following criteria:

CHAPTER 8 – REFORESTATION SUPERVISION, INSPECTION, EXAMINATION, AND
CERTIFICATION
a. Naturally Regenerated Area. Implement a grid size of 2.6 chains (170 feet) using
a 1/100 acre plot size (radius of 11.8 feet).
b. Artificially Regenerated Area (Planted). Implement a grid size of 2.6 chains (170
feet) using a 1/100 acre plot size (radius of 11.8 feet).
II. Fourth and Fifth Year Stocking Examination. These will include surveys of both
artificial and naturally regenerated plantations. On the Caribou-Targhee, these will be the
primary examinations for certifying reforested areas. Fourth year exams will be for naturally
regenerated areas where successful reforestation is highly probable and third year exams were
not done. This exam is to be done in the last half of the fourth growing season following
scarification for naturals. Only one exam is done in this situation to be more cost effective. Fifth
year exams are conducted in the fourth season following planting and the last half of the fifth
growing season following scarification for naturals.
A. Objectives
1. Determine percent stocking of regenerated area (total satisfactorily stocked plots
divide total plots taken).
2. Determine location of stocked, nonstocked, and unstockable areas.
3. Determine crop tree stocking of area in terms of tree species, tree height, planted trees
and natural regenerated trees per acre within a 20 percent samplings error for number of trees per
acre.
B. Standards
1. Show location of plot centers on map of unit.
2. On units where third year stocking exams have been conducted, calculate the
coefficient of variation (CV) based on nonstocked versus stocked plots. Use this calculated (CV)
and a sampling error of 20 percent to calculate needed plots. Implement plot sizes described for
condition below and adjust grid size accordingly. In no situation will a grid size larger that 5.5
chains x 5.5 chains (1 plot/3 acres) be used.
3. Pace off a baseline across the long axis of the stand to estimate stand uniformity.
a. Uniform stocking. (More that 70% of unit stocked.)
(1) Naturally regenerated stands - use a 1/200 acre sized plot on a 4.0 chain grid.
Record species and tree height for up to two crop trees per plot and ocular
estimate excess trees by species and height classes.

(2) Planted stands - use 1/100 acre plots on a 4.0 chain grid. Record tree species
and tree height for all planted trees. Record tree species and tree height for
naturally regenerated trees up to a maximum of three crop trees per plot. Record
individual tree records for no more than all planted trees or three natural
regenerated trees per plot. Ocular estimate species and tree height for all
additional trees per plot.
b. Stocking not uniform. (Less that 70% unit stocked.)
(1) Naturally regenerated stands - Same as 3a.(1), except use 1/200 acre plot size
on a 3.0 chain grid.
(2) Plated stands - Same as 3a.(2), except use 1/100 acre plot size on a 3.0 chain
grid.
