Interceptor Timber Sale (#51158) – Prickett VMP 05/05/2020

SECTION C – DESCRIPTION/SPECIFICATION/WORK STATEMENT

C.1 Scope of Contract This contract is for Payment Units (1-3) in the Interceptor Timber Sale. It involves timber marking and volume estimation of approximately 73 acres in Northern Hardwoods forest types, broken down by the following descriptions:

(1) HARDWOOD SELECTION, IMPROVEMENT, THINNING (Marking & Cruising)

Payment Units 1-3: approximately 73 acres

Uneven aged stands or even-aged stands with uneven-aged or even-aged objectives consisting of a mixture of Northern Hardwood types of various size classes. These stands contain both pulpwood and sawtimber Species/Product/Unit mixes. Marking objectives are to remove trees considered high risk, defective, poor form, or mature and to maintain or develop size class structure with optimum growing stock, per the specific marking instructions.

(8) SAMPLE TREE CRUISING METHOD

Payment Units 1-3: approximately 73 acres

The Sample Tree cruising method (STR) involves measuring a specified proportion (Sample Interval) of trees in the defined sub-population. The remaining trees included for removal are tallied as count trees. With this cruising method, every tree included for removal must be visited and marked.

NOTE: USFS has not marked the Road ROW unit (4) yet for this sale. This will be done by USFS at a later date. For units that have a road running through them, contractor should still mark/cruise trees up to the edge of the existing road clearing.

NOTE: Government furnished tree marking paint (TMP) will be issued, or returned, by appointment only at the ONTONAGON RANGER DISTRICT OFFICE. The primary point of contact for all TMP transactions will be the paint custodian. This person will be identified at the pre-work meeting. BLUE paint has been designated for this sale.

NOTE: USFS will mark any and all Leave Trees.

STAND DESCRIPTION

These stands are mature, uneven-aged northern hardwood stands with a good amount of species and size class diversity. They are composed primarily of sugar maple with scattered red maple, eastern hemlock, basswood, and yellow birch. Occasional white ash and northern red oak occur in the stands. Many of the oak are large sawtimber-size. Scattered hemlock-dominated patches also occur across the area. There may be occasional quaking aspen. Stand densities are fairly similar across the stands, averaging around 140ft2 to 200 ft2 BA. There are more heavily-stocked, denser areas and areas that are more open. Amongst the hardwoods, all size classes are fairly well-represented with diameters ranging from <6” to 24”. Average DBH is ~14”.

There are several spots of established sugar maple advance regeneration (1”-2” DBH), especially in PU3.

Soils are moderately well-drained, coarse loams. These stands occur on generally productive hardwood growing sites.

DESIRED CONDITION

The desired conditions are uneven-aged northern hardwood stands with the current species diversity maintained or enhanced. The future stand should feature species other than sugar maple, including northern red oak, basswood, white ash, and black cherry. Regenerating a new age class that contains these mid-tolerant species, as well as sugar maple, and is free-to-grow from browse pressure is also desired. Hemlock inclusions are generally kept intact.

SHORT AND LONG TERM OBJECTIVES

The short term objective is to regenerate of a new age class to perpetuate the uneven-aged structure by creating canopy gaps from the removal of individual or groups of trees. Another objective is to release any existing regeneration of mid-tolerant species in the sub-canopy from overstory competition. The current species diversity should be maintained or increased by favoring species other than sugar maple. With these stands containing high amounts of mid-tolerants like white ash and northern red oak, large canopy gaps to promote their regeneration should be created.

The long term objective is maintain a healthy uneven-aged northern hardwood stand that is diverse in both species composition and structure.

REMARKS

There may be scattered, small, poorly drained pockets, seeps, steep slopes, perched water tables, or shallow bedrock areas; do not designate any trees for removal in these areas.

This prescription was written to allow flexibility to the timber marker on the ground for achieving the objective with the variety in the area. Always manage for the best tree in place. If you have questions, please contact the Kenton RD Silviculturist.

MARKING GUIDE:

Name of Treatment - Selection Harvest

Residual BA/Ac 70-80 ft2

Acres - see cover sheet

Canopy gaps should be created by removing large trees or groups of smaller trees to create favorable conditions for the regeneration of northern hardwoods and mixed upland hardwoods. Canopy gaps should generally be approximately 70’-100’ in diameter. Try to maintain the diversity in size classes while focusing on removing high risk trees. Trees with poor form or poor health should be marked for removal. Most trees over 24” should be marked for removal unless it is cull or has wildlife value. Where large trees are selected for removal, mark enough smaller trees to create drop zones for the large trees. In hemlock-heavy areas, it may be necessary to select some hemlock for removal to create drop zones. Select against sugar maple and red maple to increase diversity within the stand where opportunities exist. Focus on leaving good quality crop trees with good form and improving their growing conditions, especially in the pole-heavy sections of the stand. Favor healthy oak, white ash, basswood, yellow birch, black cherry, paper birch, and eastern hemlock for retention. Always manage for the best tree in a location. Try to create larger canopy openings adjacent to desirable mid-tolerant overstory trees, like oak and white ash, to promote their natural regeneration. The target residual basal area for these stands is 70-80 ft2/acre. In areas that are heavier to hemlock, leave the residual BA a little higher. Try to release groups of established desirable saplings in the understory from overstory competition.

If any mature aspen clones are encountered in the stand, favor the regeneration of the aspen clone over the hardwoods by removing all the overstory (clearcut) in that area. Young, healthy clones of aspen can be left intact and released from overstory competition.

DESIGN CRITERIA AND MITIGATION MEASURES

Highlighted Design Criteria, see NEPA for all of the criteria Cull trees should be left for wildlife, do not remove trees with little or no value unless they pose an insect or disease threat to the stand (A2). If cull trees need to be marked the silviculturist should be notified to look at the risk.

Treat aspen inclusions in other forest type to favor aspen.

Remove all merchantable ironwood Remove all white spruce 10 inches and greater

1/ In Timber Sale Contracts, all hardwood sawlogs will use 50% minimum net scale in gross %, due to limitations in TIM. Cruising will use 95% minimum net scale for small diameter logs (9.6 – 11.5 DIB).

2/ Seventy percent applies to rot, voids, and char. Mechanical type defects such as sweep, crook, spider heart, and ring shake will not be considered.

Reasonably straight - When the true line of a minimum length piece does not deviate more than ½ the inside diameter of the small and plus two inches from a straight line drawn between the centers of the ends of a piece.

The maximum deflection allowed is what will fit in a 20-inch cylinder.

A minimum tree must include at least one piece that meets minimum specifications.

** Product heights are now measured to the nearest foot. All heights are measured in feet from the ground on the high side of the stump.

1. Conifers – measure total height (to the tip) in feet and the cruise program will calculate the 4” cut-off.

2. Hardwoods (includes Aspen) – measure the height in feet to the 4” top.

3. Sawtimber – cut-off point or “stoppers” will follow our regular practices. Measure sawtimber height in feet. Secondary product height will be measured as described in item 1 or 2 depending on the species.

4. Default dib’s are already built into the equations;

Pulpwood = 4.0” Sawtimber = 9.6” (hardwood) = 7.6” (mixed conifers, pine)

5. On trees with a broken, dead, or deformed top, record the height to the point where the 4” top or the tip would have been if the tree were still growing normally, then record defect to account for the missing volume.
