SECTION C – DESCRIPTION/SPECIFICATION/WORK STATEMENT

C.1 Scope of Contract This contract is for Payment Units (1-7) in the Explorer Timber Sale. It involves timber marking and volume estimation of approximately 181 acres in Northern Hardwoods, red Pine and Aspen mix forest types, broken down by the following descriptions:

NOTE: Layout has NOT been completed in these units. Unit boundaries will be marked with three orange slashes above DBH, facing into the unit, and stump marks made with orange paint;

except for the common (shared) unit boundaries which will be marked with two slash mark on both sides of the tree above DBH and stump marks. The Forest Service will traverse all units with GPS equipment prior to 6/30/2020, and modifications to estimated acreages will be made at that time. NOTE: Please contact James Pelkola at 906-852-3500 ext8524032 for clarification.

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

Payment Units 7: approximately 11 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.

(2) PINE AND SPRUCE THINNING (even-age) (Marking & Cruising)

Payment Units 1, 2, & 6: approximately 94 acres

These stands are second and third entries, and generally are heavier to sawtimber-sized trees.

The objectives are to remove high risk trees and thin the remainder of the stand to the desired residual basal area and spacing specifications. Skid trails are generally in place from previous harvest. When applicable and at the discretion of the COR, marking objectives include establishing skid trails prior to thinning to the desired residual basal area and spacing guidelines between trails.

(3) CLEARCUT/REMOVAL CUT (Marking & Cruising - where all trees are counted)

Payment Units 3-5: approximately 76 acres

Generally in a clearcut or removal cut, where all LIVE and/or DEAD trees that meet minimum specifications for size or species are designated for removal EXCEPT for trees marked as RESERVE TREES, LEAVE TREES or trees within PROTECTED

AREAS.

Explorer Timber Sale (#51152) – Prickett VMP 05/05/2020

In Payment Units where designated Species are too variable for Area Estimate Cruising methods, trees designated for removal will be marked with a paint spot at eye level to verify the tree was counted – a stump mark is not generally required.

(4) SAMPLE TREE CRUISING METHOD

Payment Units 1-7: approximately 181 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 (8) 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 plantations of red pine and eastern white pine established in approximately 1936. They are composed primarily of red pine and eastern white pine, with scattered northern red oak, paper birch, red maple, and aspen. There are a few small inclusions of mature eastern hemlock. These stands are overstocked, with stand densities frequently greater than 200 ft2/acre BA. The diameter range for pine is 8” to 20”, with an average DBH of ~14”. These stands have been thinned at least once before.

The eastern half of PU1 is mostly eastern white pine, while the western half is heavier to red pine. In the east of both PU1 and PU2, small inclusions of paper birch, aspen, red maple, hemlock, and oak occurs.

Soils are sandy and well-drained to excessively drained.

DESIRED CONDITION

The desired condition for these stands are to be healthy, mature stands of red pine and eastern white pine with the current species diversity maintained or enhanced. The eastern white pine should be managed in conjunction with the red pine in these stands, both receiving the same thinning treatment. All high-risk trees should be removed. Aspen inclusions within these stands should be regenerated.

SHORT AND LONG TERM OBJECTIVES

The short term objectives are to thin the red pine and white pine to alleviate the overstocked conditions and redistribute growing space, light, and nutrients to the residual stand. Other objectives are to harvest all high-risk material in the stand and regenerate the aspen inclusions.

The long-term objective is to maintain healthy stands of mature red pine and white pine with some diversity in species and structure into the future.

REMARKS

These units occur on the ridgeline above Prickett Lake. Located along FR-2270.

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 - Commercial Thinning

Residual BA/Ac: 90-100

Acres - see cover sheet

Thin the red pine/white pine down by about 40% to a basal area no lower than 90-100 ft2 per acre. Where the residual DBH will be closer to 12”, leave a slightly lower BA of around 90 sq.ft. Where the residual DBH is closer to 16”, leave the BA a little higher. Thin from below by removing trees from suppressed, intermediate, and some co-dominant crown classes as needed to improve the quality of the stand and achieve BA target. Thin the white pine and red pine in the same manner. Remove all high-risk jack pine and over-mature aspen. Mark enough trees for removal to allow for harvest operability. In more open areas where the current BA is already less than 90-100 ft2., leave a majority of trees and only mark poor formed, high risk individuals for removal. All high risk aspen, maple, fir, pine, and spruce should be selected for removal throughout all three units. Retain healthy northern red oak and release from overstory competition if possible.

Inclusions of mature aspen should be treated as a clearcut to regenerate the aspen. Mark all trees for removal in this area except healthy paper birch, northern red oak, eastern white pine, and red pine. Treat all aspen inclusions within these stands in a similar manner.

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.

These stands are composed of varying amounts of northern red oak, quaking aspen, bigtooth aspen, red pine, eastern white pine, and paper birch. There is a small amount of poor-quality red maple and sugar maple scattered throughout the stands. There may also be an occasional mature jack pine. The amount of aspen varies throughout these stands, with some areas having at least 40 ft2/acre BA of aspen, and other areas having no mature aspen at all. Patches of aspen sprouts can be found throughout the understory. There is a consistently good amount of advanced oak regeneration throughout these stands, but much of it is heavily browsed by deer.

These stands, especially PU3, contain some small areas that are heavier to red pine/white pine. Densities are fairly variable within these stands, but generally range between 90 – 140 ft2/acre BA. PU4 is the least dense and most open unit. Diameters range between 6” and 16” with an average DBH for aspen of ~12”.

PU4 is heavier to oak than the other units, and contains less aspen. Soils are sandy and well-drained to excessively drained.

Portions of these stands should be regenerated to dense, young aspen seedlings averaging ~>3200 trees per acre, with other areas of the stand remaining relatively intact. Existing oak regeneration should be released and left in a free-to-grow position. Healthy oak, red pine, and eastern white pine should be retained in the overstory to provide a seed source and structural diversity to the stand. This will in effect create a new age class of aspen and birch with sections of pine and oak regeneration, underneath a low density canopy of mature northern red oak, white pine, and red pine.

The short term objective is harvest all the high-risk aspen and paper birch to regenerate aspen/paper birch, while retaining healthy overstory oak, red pine, and eastern white pine. All high risk and unhealthy trees should be removed from the site. Existing advance oak regeneration that is healthy and possesses a good crown should be released from overstory competition.

The long-term objective is to maintain a diverse stand of northern red oak, aspen, red pine, eastern white pine, and other native species that is diverse in structure.

These units occur on the ridgeline above Prickett Lake. Units are located along FR-2270. PU5 occurs in three pieces.

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

Name of Treatment – Stand Clearcut (w/leave trees)

Residual BA/Ac: 50-60 ft2/acre

Acres- see cover sheet

Mark all mature aspen and paper birch for removal to regenerate the aspen/birch component. Mark all high-risk and poor-quality hardwoods for removal to create more room for aspen/birch regeneration. Mark all high-risk jack pine for removal.

Retain healthy northern red oak, eastern white pine, and red pine. Retain other hardwoods, such as sugar maple, when they possess good form and are not likely to be inhibitive to aspen regeneration. Try not to leave lone oaks by marking all the surrounding aspen. Retain a few trees around the oak in this situation to protect the microsite.

Red pine, white pine, and northern red oak with poor form and/or poor health should be removed. Existing advanced oak and white pine regeneration in the understory with good crowns should be released from overstory competition if possible. Because of the patchy-nature of the aspen, there are sections of the stands where very few trees will be harvested this entry, especially in PU4.

The target BA for this stand is 50-60 ft2/acre. This represents a likely residual BA after removing all the aspen, paper birch, and other high-risk trees as described above. This treatment is intended to be a clearcut to regenerate the aspen/birch component while retaining a significant amount of healthy leave trees. There may be areas that need to be left at a higher or lower residual BA than the prescribed target.

Areas that are heavier to red pine and white pine should be thinned by approximately 40% to a BA of approximately 90-100 ft2 per acre.

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.

PU6 is a mature red pine plantation with scattered eastern white pine, northern red oak, and red maple. An occasional white spruce occurs. There is a fair amount of regeneration of oak, red maple, white spruce, and balsam fir in the understory. This stand is overstocked with a stand density of approximately 180 ft2/acre BA. Pine diameters range between 10” and 18”, with an average DBH of ~14”. This stand has been thinned at least once before.

Soils are sandy and well-drained to excessively-drained.

The desired condition for this stand is to be a healthy, mature red pine plantation with the current species diversity maintained or enhanced. All high-risk trees should be removed. Aspen inclusions within these stands should be regenerated.

Following the harvest, this stand should receive a low-intensity prescribed burn. The desired result of the burn would be to leave the understory of this stand free of understory hardwood competition and excess slash left over from the harvest operation.

The short term objectives are to thin the red pine to alleviate the overstocked conditions and redistribute growing space, light, and nutrients to the residual stand. Other objectives are to harvest all high-risk material in the stand and regenerate any aspen inclusions.

Following the harvest, this stand should receive a low-intensity prescribed burn to control understory vegetation, eliminate hazardous fuel load build-up (leftover from the harvest operation), and recycle mineral nutrients back into the soil.

The long-term objective is to maintain a healthy stand of mature red pine with some diversity in species and structure into the future.

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

This stand is slated for a prescribed burn following completion of the timber sale.

This stand is a mature, uneven-aged northern hardwood stand with a good amount of species and size class diversity. Species composition is a mix of red maple, sugar maple, yellow birch, eastern hemlock, and basswood.

Occasional white ash and northern red oak may occur. Scattered hemlock-dominated patches also occur across the area. There may be occasional quaking aspen. Stand density averages around 140 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 a few spots where the trees are more pole-sized.

Soils are sandy loams, and range from moderately well-drained to somewhat poorly drained.

The desired condition is an uneven-aged northern hardwood stand with the current species diversity maintained or enhanced. The future stand should feature species other than red maple and sugar maple. Yellow birch should be promoted. Regenerating a new age class that contains mid-tolerant species, as well as maple, and is free-to-grow from browse pressure is also desired. Hemlock inclusions are generally kept intact.

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 red maple and 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.

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.

PU7 occurs in two separate pieces along FR-2276H.

Name of Treatment - Selection Harvest

Residual BA/Ac: 70-80 ft2/acre

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. There is a good mix of size classes in most stands, with a heavy concentration in the 10”-16” range. 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. 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 yellow birch, oak, black cherry, white ash, basswood, paper birch, and eastern hemlock for retention. Always manage for the best tree in a location. The target residual basal area for this stand is 70-80 ft2/acre. In areas that are heavier to hemlock, leave the residual BA a little higher.

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.

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.

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.
