Sample Silvicultural Prescription
Unit #407 (45 acres) Thin for Hazardous Fuels Reduction
Treatment Method Preference: #1– Leave an average of 200 TPA (min 150 TPA, max 250 TPA) with a combination of trees >7” DBH (>6” for LP), trees 4”-6.9” at DBH (5.9 at DBH for LP), and trees >2’ tall and <4” DBH. Target spacing is 15’ with a 50% variance, spacing may vary between 7’ and 21’ (= avg. 200 TPA). Consider species preference, size, and best tree in this order when selecting leave trees.
Species Preference = WL, DF, LP, S, GF and AF. Leave all WP, PP, hardwood species:
these trees will not be counted in TPA/spacing requirements.
Preference of Size = largest to smallest.
Best Tree = Good crown form, live crown ratio >40%, good leader growth, straight bole, without significant defect or damage and insect/disease free.
Trees >7” DBH (>6” for LP) – The only trees meeting these specifications allowed for cutting will be identified by and approved by an authorized inspector in skid trails or landings. These identified trees will be left whole in the unit as down logs for nutrient recycling and wildlife habitat.
Trees 4”-6.9” at DBH (5.9 at DBH for LP) All cut trees in this size class will be whole tree yarded to landings, de-limbed and decked in a way that makes the decks accessible to self loading log trucks.
Treatment Method Preference: #2 Masticate all trees within the unit necessary to meet the same requirements as treatment method preference #1(above). Exception: Trees will not be yarded to landings, de-limbed and decked.
Slash Treatment Trees >2’ tall and <4” DBH + all activity fuel All piling will be done with an excavator.
Treatment Method Preference: #1 Remove to landings all activity generated slash in excess of 10 Tons/acre, with a depth of no more than 1’. Excavator pile landings. Retain all existing down logs for nutrient recycling and wildlife habitat.
Treatment Method Preference: #2 Masticate within the unit while retaining all existing down logs for nutrient recycling and wildlife habitat.
Amendment No. 01, dated 04/21/2014 Attachments, Page 26 of 40
Treatment Method Preference: #3 Excavator pile within unit; pile all activity generated slash in excess of 10 tons/acre, with a depth of no more than 1’ while retaining all existing down logs for nutrient recycling and wildlife habitat. Locate piles 100’ from road edge and PVT boundary and in opening to minimize damage to leave trees and snags during burning.
All Other Considerations - (1) Minimize soil scarification and detrimental soil impacts to less than 15% of unit area; including landings. (2) Minimize damage to the leave tree boles. (3) Any tree designated for retention that poses a safety hazard may be felled by the contractor without prior approval of the Forest Service. All such hazard trees felled to provide for safe work conditions will remain adjacent to the stump and will require inspector approval prior to skidding or yarding. Leave all snags standing unless they create a hazard. Snags will not be counted toward TPA/spacing requirements. (4) Maximum stump height 6” with no lower live limbs left on the stumps and tree completely severed from the stump. (5) Trees <2’ in height will not be counted toward TPA/spacing requirements. (6) Slash approximately 30% of the maple, willow and serviceberry in areas where they are dense and decadent. (7) Leave a 15’ wide strip of seedling/saplings along drivable road edges for wildlife cover. (8) There is one timing option for this unit; log in summer when the soils are dry by the “hand feel” method (usually after July 15th). Skid trail must be 100 feet apart when summer conditions exist. (9) Prior to project implementation any equipment used must be weed washed and inspected. (10) No timber products may be hauled from contract area. (11) Leave trees shall not be left directly under over-story leave trees. (12) All excavator piles must be free of soil, reasonably compact, and no less than 6 ft. in height. (13) Protect all survey monuments. (14) 75% of chips from masticating must be <3’ in length, 25% of chips from masticating may be >3’ in length for material <5” diameter, however must be no more than 1’ in height. Material >5” in diameter will have no length limit, however must be no more than 1’ in height. (15) Hand treatment may be required on portions of the unit that exceed 35% slope or were excessive leave tree damage would occur due to tight over story spacing.
TPA = Trees per acre > = Greater than < = Less than > = Greater than or equal to “ = Inches unit of measure ‘ = Feet unit of measure DBH = Diameter of tree at breast height (4 ½ feet from the ground, on the uphill side) WL = Western Larch DF = Douglas Fir LP = Lodge Pole Pine S = Spruce GF = Grand Fir AF = Alpine Fir WP = White Pine PP = Ponderosa Pine Hardwood species = Birch & Mountain Maple.

DETAIled InstructionS
TREE EVALUATION CODES
Codes Explanation
Satisfactory Leave Trees The totals of S1 and S2 trees are used in the thinning quality calculation.
S1 or check mark
Acceptable tree; tree was left that met the leave tree specifications.
S2 Tree was left that exceeds the maximum d.b.h. to cut, and the prescription/contract specified this tree counts in the acceptable trees per plot calculation when no tree within the thinning range exists.
S3 Tree was left that exceeds the maximum d.b.h. to cut but is considered a surplus tree and is not included in the acceptable trees per plot. This value is important to record in order to calculate total trees per acre in the post treated stands. Refer to the prescription, which will specify if these larger trees are considered surplus in all cases, or only when there are sufficient trees within the thinning range to meet the allowable density.
S4
Tree was left that was of the species or condition that was to be ignored; it is considered a surplus tree and not included in the acceptable trees per plot. This value is important to record as it is needed to calculate total trees per acre in the post treated stands. (WP & PP)
Non-Stocked Areas The totals of non-stocked areas are used in the thinning quality calculation.
N1 An opening exists on the plot where no tree exists. Recording this on the plot form justifies fewer than minimum trees on a plot.
N2 An opening that was created by cutting a tree due to poor form, insect and disease or other conditions as required by the contract or prescription (skid trail or landing). Recording this gives credit for cutting a tree that should be cut even if it lowers the stocking below minimum levels.
Improperly Cut trees – Category A deficiencies These deficiencies are uncorrectable and influence the thinning quality calculation. Regardless of the thinning quality, rework cannot be done to correct these problems.
A1 Tree was cut that should not have been; it that met all leave tree specifications, and did not exceed the maximum trees per plot.
A2 Tree was cut that should not have been because it exceeded maximum d.b.h. to cut. This could instead be coded A1 but is more specific using this code.
A3 Satisfactory leave tree was damaged in the thinning operations; may have been damaged during cutting, slash treatment or any aspect of the operations.
A4 Wrong leave tree was left. It was the wrong species, a better tree existed in the spacing or competitive area, or similar reasons. Do not also code the tree that was incorrectly cut as a deficiency
Attachments, Page 33 of 40
Excess Trees remain – Category B deficiencies These deficiencies are correctable and influence the thinning quality calculation. Reworking the area and cutting more trees can correct these errors.
B1 Tree met tree specifications but should have been cut to meet the allowable stocking density, or it was too close to a leave tree.
B2 Tree should have been cut because of damage, insect and disease or poor form or otherwise indicated as a tree that is to be cut regardless of other trees on the plot. Refer to prescription for unacceptable levels of insect, disease or damage or the characteristics of other trees to be cut.
B3 When girdling is required, this code indicates that a tree was not girdled or not adequately girdled that should have been. The prescription/contract must specify if this will be considered a B or C deficiency. As a B deficiency, there is less tolerance and will affect the quality calculation.
B4 When pruning is required, this code indicates that a tree was not pruned or not adequately pruned that should have been. The prescription/contract must specify if this will be considered a B or C deficiency. As a B deficiency, there is less tolerance and will affect the quality calculation.
Other deficiencies – Category C deficiencies These include a variety of other discrepancies that generally can be corrected. The contract/prescription must specify the maximum C deficiencies that are allowed, after which rework is required. In general a greater number of these deficiencies can be allowed before it affects the overall results of the thinning activity, therefore there is some tolerance to a small number of these, particularly if there is a cost savings.
Refer to contract for maximum Cat C deficiencies allowed. Recording the C deficiencies with a tally by type (i.e. C1, C2, etc) is desirable.
C1 Tree was not completely severed from the stump.
C2 Tree was hung up in another tree or other debris.
C3 The stump was higher than the maximum allowed.
C4 A “small tree" was left. Small trees are defined by the contract/prescription and reflect those trees that are required to be cut but do not pose a strong competition to the larger trees.
C5 When girdling is required, tree should have been girdled or was girdled improperly. The prescription/contract must specify if this will be considered a C or B deficiency. As a C deficiency, there is tolerance for errors within the stand.
C6 When pruning is required, tree should have been pruned or was pruned improperly. The prescription/contract must specify if this will be considered a C or B deficiency. As a C deficiency, there is more tolerance for errors within the stand.
OTHER DEFICIENCIES – CATEGORY D DEFICIENCIES
These include a variety of other discrepancies that generally can be corrected. Category D deficiencies will be monitored from plot center; however will include entire area visible from plot center. Record the D deficiencies with a tally by type (i.e. D1, D2, etc) in the remarks section of plot form.
D1 Excessive soil disturbance; refer to contract F-2 Performance Period, Soils.
D2 Excessive slash depth; slash and activity generated fuel greater than 1ft in depth or 10 tons/ac.
D3 Piles unacceptable; piles must be greater than 6’ in height reasonably compact and free of soil.
D4 Excessive leave tree damage.
Less than 10 Category C deficiencies per acre will be considered acceptable. Greater than 10 Category C deficiencies per acre will require rework.
Category D deficiencies greater than 10% of the unit will require rework.
Category D equation: sum of D x 0.25 / # of plots x 100 = % quality

Contract Specifications- this is only a highlight of some of the requirements of the project; refer to the prescription and contract requirements for the additional information.
m Acceptable stocking density in trees per acre provided in the prescription. An average, minimum, and maximum are provided.
n Acceptable trees per plot is calculated from the acceptable trees per acre based on plot size.
Calculate the minimum, maximum, and average. The minimum and maximum are required for evaluating trees on the plot.
Trees /ac x plot size = trees/plot Example: 250 trees/ac x 1/50th ac plot = 5 trees/plot o Spacing when spacing method is used for leave tree selection. Refer to prescription.
Example: 10 x 10 foot average spacing.
p Plot size is either specified in the contract or determined by inspector. The same plot size must be used on the entire unit; it should yield a minimum of 4-6 trees per plot (fully stocked plots). Utilize larger plot when variability in the stand density exists and it is desired to maintain that variability.
q Minimum cut height is stated in the prescription/contract and reflects the shortest tree that is required to be cut, represented in inches of height from ground level.
r Maximum cut d.b.h. is stated in the prescription and reflects the maximum d.b.h. for trees to be cut. Cutting trees larger is a violation.
s Maximum Cat C is the maximum allowable Category C deficiencies allowed before rework is required. The maximum is stated in the prescription or contract.

Plot Inspection Header Information Block
Explanation t (bottom of page) Thinning Quality calculation: ratio of Category A and B deficiencies to total satisfactory leave trees and credit for non-stocked points.
Quality % = 1.00 - Totals of col. 6 + col. 7+ col. 8 + col. 9 X 100 Col 3 + Col. 5 Note: if there are a high number of deficiencies relative to allowable trees, the quality may be a negative number. This would indicate a need for re-work or other action to achieve acceptable work.
Category C deficiency calculation after Cat C deficiencies are totaled on the unit Cat C trees per acre = Total col. 10 x reciprocal of plot size = tpa No. of plots
Bottom of page Contractor inspector must sign, date and certify that all information is correct and accurate before providing the records to the Government.
Inspection Sheet Column
Instructions/explanations
1 Locate and mark plot center on the ground. Record the plot number in column 1.
2 Locate and examine each tree on the plot selected for leave, and trees that have been cut.
Record the Evaluation Code on the upper row of blocks for each tree on the plot, any tree that should have been left on the plot, and non-stocked points. Utilize the Tree Evaluation Codes on the back of the form. Do not include trees with a C deficiency (see column 10).
If required by the contract, record the species of each tree in the lower block. Record the species of a tree that was cut that should not have been with a diagonal line through it.
If required by the contract, estimate and record the average diameter and height of the trees after thinning the plot. These are estimates that can be used for the post-thinning stand condition.
In the remarks area, provide comments on tree condition, plot conditions, or other information useful to understand the inspection results.
3 Based on the results of column 2, tally the satisfactory S1 and S2 leave trees on each plot and record in column 3. This number cannot exceed the maximum trees per plot (block n) and would only be less than the minimum when there are non-stocked points (N1, N2) or Category A deficiencies recorded on the plot. If this number is not within the max/min range, then the codes in column 2 need to be re-evaluated. When it exceeds the maximum, there are trees coded satisfactory that should be surplus (S3 or S4) or excess (Cat B). If it is below the minimum, and there are no points that satisfy the definition for non-stocked points (N1, N2), then an acceptable tree was cut (Cat A). The appropriate tree(s) should be re-coded.
If an entire plot consists of trees which exceed the max. d.b.h., or in combination with Satisfactory (S1) trees, the maximum satisfactory leave trees in column 3 is the maximum trees/plot (block n).
4 Based on the results of column 2, tally the number of acceptable trees left because they exceeded the maximum d.b.h. (S3); or were trees that were ignored during the thinning (S4).
These trees are surplus to those on the plot used in the acceptable trees per plot calculation based on 1) the prescription or 2) because these are in addition to the maximum acceptable trees per plot. This column is not used in the quality calculation however is useful in evaluating total trees remaining on the unit of all size classes.
5 Tally the non-stocked points on the plot (N1, N2). If the entire plot is an opening, the maximum number of N1 credit is the minimum acceptable trees/plot from block (n).
6 Tally the total of trees cut that should not have been cut (A1, A2).
Attachments, Page 36 of 40
Column Instructions/explanations
7 Tally the total trees that should have been left but were damaged during the operation (A3) or an error in selecting the correct leave tree (A4), hence the best or correct tree was cut.
8 Tally of excess trees which are trees that should have been cut (B1, B2) and cause there to be more trees per acre than acceptable, trees that are spaced too close to a satisfactory leave tree, or trees that should have been cut to meet contract specifications. Poor thinning quality can be improved by reworking areas with excess trees.
9 Tally of trees that should have been girdled or pruned or were done so incorrectly (B3 and B4). Poor quality can be improved by reworking areas with excess trees. Note that excess girdled or pruned trees could instead be a Category C deficiency. The FS must determine this prior to start work; specify on back of inspection form.
10 Tally other types of deficiencies on the plot. Tally by type of error utilizing the space below column 10. A maximum number of C deficiencies must be identified prior to start work (refer to prescription or contract). Areas that exceed this level must be re-worked. Refer to explanation for block s. Category C deficiencies are not included in the quality calculation.
After all plots are taken, total the columns. Calculate thinning quality and determine if the Category C deficiencies are within the contract allowance. .
Thinning Quality (see block t) Quality % = 1.00 - Totals of Column 6 + column 7 + Column 8_+ Column 9 X 100 Column 3 + Column 5 Note: if the numerator exceeds the denominator, a negative thinning quality will result.
Category C trees per acre = Total of Column 10 X reciprocal of plot size No. of plots Compare results with block s.
Additional calculations that may be conducted by the Government to determine if thinning met the prescription goals.
Average number of satisfactory leave trees (S1 and S2 only) per plot:
Sum of Column 3 = avg. trees /plot No. of plots
Average number of satisfactory trees (S1, S2 only) per acre:
Sum of Column 3 X reciprocal of plot size = trees per acre No. of plots
Average trees per acre in the diameter range being thinned ( S1, S2, A3, A4, B1, B2 trees):
[Sum of Columns 3 + 7+8 ] X reciprocal of plot size = trees per acre No. of plots
Average trees per plot in the diameter range being thinned:
[Sum of Columns 3 +7+8 ] = avg. trees /plot No. of plots
Average Total trees per acre (all trees larger than “small trees” and min. cut tree height):
[Sum of Columns 3 + 4 + 6 + 7 + 8 ] X reciprocal of plot size = trees per acre No. of plots
