GRAYLING FOREST MANAGEMENT UNIT COMPARTMENT REVIEW RESENTATION
COMPARTMENT # 18 ENTRY YEAR: 2010
GIS Compartment Acreage: 2070 County: Oscoda
Revision Date: September 12, 2008 Stand Examiner: Joan Charlebois Legal Description: T28N R2E Sections 16, 17, 18, 19, 20, 21 & 29 Elmer Township – North Part Management Goals: To maintain forest health, productivity, sustainability, species diversification, and structural diversity throughout the compartment while providing for multiple use and visual management. Soils and Topography: The terrain is flat to gently-rolling, except for in the southeast portion where ice-contact kettle holes - some of them very steep and hitting the water table - can be found. Soils are primarily Grayling, Graycalm, Roselawn & Rubicon Sands. Ownership Patterns, Development, and Land Use in and Around the Compartment: The compartment encompasses state land spread across seven sections, with a significant amount of private property interface. The compartment's south half has the most fractionalized ownership, in 40 to 120-acre blocks. Three forties have no legal access. Adjacent property development is largely seasonal/recreational, although there are some year-round residences. Unique, Natural Features: Ice-contact kettle holes provide unique micro-climates in this largely flat, outwash plain area. Archeological, Historical, and Cultural Features: Old railroad grades cross through the compartment and large, turn-of-the century logging era pine stumps are common. Special Management Designations or Considerations: If access across private property for management purposes cannot be obtained, consider for disposal the SENE of section 19 and the W1/2SW of section 20. To provide more direct access to state land in the W1/2SW section 29, consider pursuing for acquisition the narrow strip of private property separating that block of state land from Farrington Road. Watershed and Fisheries Considerations: Remnants of LaBelle Lake (stands 99 & 100) occur within stand 1. Wildlife Habitat Considerations: The compartment’s jack pine, aspen, oak, upland brush and grass cover types provide potential habitat for a variety of game and non-game wildlife species, including deer, grouse and opening-dependent songbirds. Mineral Resource and Development Concerns and/or Restrictions: Surface sediments consist of glacial outwash sand and gravel and postglacial alluvium. The glacial drift thickness varies between 600 and 800
feet. Beneath the glacial drift is the Coldwater Shale. There is not a current economic use for the Coldwater Shale. Gravel pits are located two miles to the east and potential appears to be good. The entire compartment is leased and Sections 16 - 21 have been developed for the Antrim Shale. Sixteen well sites, associated flow lines and a pump station occur within the compartment. Vehicle Access: Most of the compartment is accessible by county roads, including Town Line, Pennsylvania Crossing, Oak Lake, and Farrington Roads, and also by a network of two-tracks and gas well access roads. The W1/2SW of section 29 is not directly accessible off Farrington Road (there is a narrow strip of intervening private) but the block can be reached through compartment 19 to the west. Two blocks should be considered for disposal (SENE section 19 and W1/2SW section 20) because the State has no legal access to them. Survey Needs: Much of the area had been surveyed by the State in the last thirty years, and nearly all of the corners were located despite the deep snow. Additional corners needed for establishing private lines are likely to be identified during timber sale field work when the ground is not snow-covered. Recreational Facilities and Opportunities: No designated trails or facilities occur within the compartment, but the habitat types provide good opportunity for deer and grouse hunting. Fire Protection: The compartment has relatively large stands of jack pine, ranging from young plantations to mature poletimber. Gas wells and buried pipelines occur within the compartment, although none were identified as hydrogen sulfide hazards. Several nearby water sources (Oak, Perry, Rudd & Indian Lakes) are all surrounded by private property. LOTS Compartment Acreage:___2034______

GRAYLING FOREST MGT UNIT Compartment: 18Proposed Treatments With NO Limiting Factors
Entry Year: 2010
4 J6 26 60 47 mature final harvest 1 natural regenerationoak
Variable size/density JP pole stand with very overmature JP saw, small inclusions of TA and BTA (also variable in age/size, with some very overmature stems). Nice oak seedlings and saps O1-O2. Some scattered NPO and RP. Final harvest the JP (1-stick and up) and aspen (2" and up). Retention: leave all oak and RP (`6% of BA). Goal is a mix of natural regeneration: oak, aspen and pine. Used previous SI.
Fmd :comnts
6 O8 26 90 52 sparse final harvest 2 natural regenerationoak
NPO stand, progressively breaking up. Popular with fuelwood cutters. Contains <10BA each of JP saw & younger poles, TA, BTA & RM. Nice oak regen in pockets, but not enough to average out to O1. Some WP seeding in. Final harvest the oak, JP and aspen, marking to leave ~5 BA scattered or in clumps of the healthier oak for retention, and leaving all other pine. Goal is a mix of natural regen, including oak, aspen and pine. Used previous SI.
Fmd :comnts
7 J6 27 45 58 mature removal 1 natural regenerationoak
7 & 107: Mature JP poles with a component of very overmature JP saw. Pockets of recent mortality and windthrow. Minor component of NPO saw. Aspen inclusions with mature-to-overmature stems. Nice advanced oak regen, 01-03. Harvest the JP & aspen. Leave the oak and any other pine (`15% retention). Goal is to release the existing oak regen and also regenerate the aspen. Stand 107 is that part south of Oak Lake Road. Included along stand 107's southeast boundary is a strip of overmature TA. Used previous SI.
Fmd :comnts
12 J6 117 55 47 two aged removal 1 natural regenerationoak
Variable age/size/stocking JP in 3 classes: mature JP poles, young poles, overmature JP saw. Small inclusions of U/G and very overmature TA. O0-O3 in seedlings and saps. Half a dozen ground blinds. Averaged age & SI with previous. Harvest the merchantable JP & aspen in order to release the established oak regen and to regenerate the aspen. Retention: exclude from sale boundary the ~ 4-acre penisula that extends into stand 16, and create a 1-acre island east of stand 14 (~4% of total area).
Fmd :comnts
15 R6 9 44 61 immature thinning 1red pine
Stand 15 & 115: RP plantation. Variable stocking & areas of stunted trees where planted around a lot of residual NPO, TA & JP (primarily N of P. C. Road). ~10% of stems have moved into the saw class. Stand 115 is that part S of P.C. Rd. Third row thin. Dated plantation based on old records.
Fmd :comnts
16 A8 19 52 57 sparse final harvest 3 natural regenerationaspen (upland)
Small sparse mixed stand of overmature TA (more to N) and NPO, both recruiting into the CWD layer. JP mixed in along the boundary with stand 12. A strip of oak had been cut along the NW edge: there now are nice large oak stump sprouts. Both the aspen and oak are equally poorly represented in terms of BA; was typed as an aspen stand based on plot occurrence frequency by species. Harvest the merchantable JP, aspen and oak. Due to small stand size, do not leave retention other than the sub-merchantable stems. The goal is to regenerate the aspen & oak before it completely breaks up, and release the existing oak regen. Used previous SI.
Fmd :comnts
17 R6 3 44 62 immature thinning 1red pine
Planted in '64 (per old records). RP with ~1/3 of stems just crossed over into the saw class. Was planted around JP, NPO and old pine stumps. More oak residual to the north. JP saw limby, cull. Stunted RP around the residual. Some weevil damage and doubles, but generally decent quality RP. Third-row thin the RP, remove all JP, and cut only that oak needed to get through the rows. Stand 117 is that part south of P.C. Rd.
Fmd :comnts
27 O8 163 88 52 sparse final harvest 2 natural regenerationoak
Varying mixture of NPO saw (low-density, declining, a lot on the ground) and aspen (mostly TA, ranging from poles to overmature saw). Old notes indicate that the oak was cut during 1967 to 1971 and mast trees were left. The stand has areas of nice oak regen (large stump sprouts and single saps) up to O3, but it averages only to O1. U inclusions are common. Two narrow bands of JP that were prescribed but not cut last YOE are also included within the stand. Cut all oak greater than 6" DBH, and all merchantable JP, aspen and RM. Leave the few RP & WP (<5BA). The goal is to salvage the mature-overmature trees, release the advanced oak regen and maintain aspen as a component within the stand. Retention: in additon to the residual oak and pine, create four 1-acre islands (three on an E-W line through the stand's S1/2 and one in the stand's N1/2, avoiding areas with good advanced oak regen. Used the previous SI. See locked comments.
Fmd :comnts
64 O9 52 99 55 mature shelterwood-seed 2 natural regenerationoak
Decent-quality RO saw with ~10 BA each of WO saw, RO poles, BTA, and NPO. The stand's perimeter on the flats has lower-quality and lower-BA oak, while the central higher ground has the denser, nicer oak. All RM, PB, TA and pine were cut in '90-'91 under #013-90-1, all oak were left. The harvest area -- except ~13 acres south of the E-W two-track -- was Rx burned in '99 under FTP C72-412 and in 2000 under FTP C72-429, both with the goal of reducing the RM competition. The understory within the burn area is much more open, averaging Mr1 versus the unburned area's Mr3+. The stand area was heavily worked-over by deer digging through the snow down to the leaf litter. The stand should have a regen cut applied before the benefits of the Rx burning are lost. Per August 21, 2008 field review, additional prescribed burning is not needed; apply a shelterwood cut, aiming for 50% crown closure, and create two 90-foot diameter regen gaps per acre. Used previous SI.

GRAYLING FOREST MGT UNIT Compartment: 18Proposed TreatmentsWith Limiting Factors
Entry Year: 2010
57 R6 16 44 57 immature thinning 2red pine
TREATMENT LIMITING FACTORS:
Old notes indicate planted in '64. ~1/3 of stems just moved into the saw class. Some defect (porky, weevil, doubles) but nowhere near stand 61's level. Decent-quality overall, with poorer stocking where planted around residual RM, TA & JP (more to E1/2). Third-row thin. Was prescribed last YOE but not treated due to access issues - - is in a block of state land surrounded by private. If access for managing the W1/2SW of section 20 cannot be obtained, recommend disposal of the parcel.

59 R6 2 44 57 immature thinning 2red pine
TREATMENT LIMITING FACTORS:
Old notes indicate was planted in '64. ~1/5 of stems moved into the saw class. Doubles common. Third-row thin. Access will be an issue - - is in a block of state land surrounded by private. If access for managing the W1/2SW of section 20 cannot be obtained, recommend disposal of the parcel.
Fmd :comnts
Adjacent landowner denies access
61 R9 20 37 64 low quality final harvest 2grass
TREATMENT LIMITING FACTORS:
RP plantation with atypical configuration: One and a half chain wide strips were planted (10 rows with ~10' wide spacing between rows), alternating with half-chain wide strips of grass. Old notes indicate that this was an experimental planting or, more specifically, an "Erbe Special" established in 1971. The inherent site quality itself is okay (64), but the lower planting density and tremendous amount of edge resulted in poor height growth, high taper, heavy persistent lower branches, and high weevil incidence. This lower stocking allowed stems to progress more quickly into the saw class, but the quality is very poor; easily 1 in 4 trees have defect (doubles, forked, crook, etc.). Stocking is poorer to the east. Plots were taken within the planted strips; BA there averaged 130. Overall stand BA, taking into consideration that 25% of the area was unplanted, is 100 BA. If access can be gained across private, final harvest the stand and allow it to revert to grass. The G-type to the east that grades into this stand has big and little blue stem and is contiguous with another larger opening with similar cover on the adjacent private. Retention: create three 1/3-acre island's, one each in the stand's W, NE & SE. This is in an area with large, old, heavily-burned pine stumps and old railroad grades. If access for managing the SENE of section 19 cannot be obtained, recommend disposal of the parcel.

Adjacent landowner denies access
63 A9 19 86 47 high risk final harvest 3 natural regenerationaspen (upland)
TREATMENT LIMITING FACTORS:
Highly variable stand. Common thread is mature-overmature aspen (TA & BTA) with the older component of large cull stems moving into the snag class. Mixed in is a little bit of everything else: a few massive oak to the NW, sugar maple, ironwood, RM & paper birch to the SW, and small clumps of RP & WP saw and poles (species other than aspen totalling 35 BA). The stand was not cut in '86 when stand 58 was cut, even though permission to cross private was obtained and the haul access went through this stand. If access is granted, harvest the aspen and RM, but leave the other species. Used previous SI. See locked comments. If access for managing the SENE of section 19 cannot be obtained, recommend disposal of the parcel.

DEDICATED CONSERVATION AREA DETAILS
Conservation Area SCA = Special Conservation Area
HCVA = High Conservation Value AreaERA = Ecological Reference Area
An aquatic or terrestrial area of the State that contains physical remains of human occupation. These are sites of cultural and historical significance that may occur upon terrestrial areas and Great Lakes bottomlands. They include thousands of Native American settlements and burial sites, as well as French and British outposts, nineteenth century logging camps, mines and homesteads. Beneath the waters of the Great Lakes, there are shipwrecks and other remains documenting the maritime trade. Such sites may be identified by Natural heritage data from the State Historic Preservation Office. Proposed treatments in this compartment will be implemented in such a manner as to maintain the integrity of these sites. Due to the sensitive nature of this information, no further detail about location is available.
