About this file
This is a timber marking prescription document from the Michigan Department of Natural Resources (DNR) for forest management activities at the Gaylord State Forest. The document provides detailed prescriptions for eleven distinct forest treatment units employing various silvicultural methods including single tree selection, crown thinning, seed tree with retention, and clearcut patch creation. The prescriptions target basal areas ranging from 5-10 BA to 80 BA across different units, with treatment areas varying in size and complexity. Key management objectives include maintaining natural regeneration of desirable hardwood species (particularly sugar maple), protecting underrepresented species such as yellow birch, elm, hemlock, and black cherry, and preserving specific ecological features including aspen clones and snag material for wildlife habitat.
The prescriptions incorporate substantial environmental protections and access management across the treatment units. Specifications mandate maintenance of Natural Rivers Buffers ranging from 150 to 300 feet along stream corridors including the Jordan River, Section 13 Creek, and Racket Creek. All units require protection of North Country National Scenic Trail pathways through marking restrictions, equipment crossing limitations, warning signage, and trail hardening specifications. Additional protections address steep terrain operability constraints, with prescriptions limiting marking to one-third to one-half slope distance on steep grades and 10-15 feet into downward-facing slopes on accessible ridge tops. The document emphasizes retention of wind-firm seed sources in clumped distributions, retention of larger beech and aspen for future snag material, and avoidance of marking higher-quality pole and sapling sugar maple stems across all treatment units.

C 58 HDWD Marking Prescriptions
2) Single Tree Selection. Target 80BA.
• 'Maintain for Regen' site condition identified in north. This area of desirable sugar maple regen might expand/contract during prep.
• Steep along northern and southern boundary. Run red line at the bottom of slopes in northern and southern boundary locations and give equipment room to work/turn.
• On steep slopes that equipment is unlikely to reach the top of, only mark 1/3 to 1/2 way Up the slope. On accessible ridge tops, only mark 10-15ft into downward facing slopes. When slopes appear completely operable, go ahead and mark. Expect some 'zero' plots during timber cruise.
• Create clearcut patches (100ft minimum) around some of the scattered aspen clones and in areas of poorer quality timber. Use 2" spec inside patches.
• AVOID marking pole/sap sugar maple stems of better form/quality
• Retain underrepresented species (y.birch, elm, hemlock, b.cherry, xlog beech, wolf/den trees, etc.)
6) Crown Thin to release crop trees & pole stems. Target 80BA.
• 'Too steep' and Natural Rivers buffer already identified in south. 'Too steep' in south might expand/contract during prep. N.C.Path is present within Nat.Riv buffer.
• Steep along north, east, and west boundary, as well as interior locations. Run red line at the bottom of slopes in northern and eastern boundary locations and give equipment room to work/turn. Where appropriate, do the same for western boundary.
• On steep slopes that equipment is unlikely to reach the top of, only mark 1/3 to 1/2 way Up the slope. On accessible ridge tops, only mark 10-15ft into downward facing slopes. When slopes appear completely operable, go ahead and mark. Expect some 'zero' plots during timber cruise.
• Retain underrepresented species (y.birch, elm, hemlock, b.cherry, xlog beech, wolf/den trees, etc.)
9) Single Tree Selection. Target 70BA.
• Maintain a 150ft Natural Rivers Buffer on the Rx’s west boundary, along Section 13 Creek. Rx layer reflects this buffer.
• NCPathway along west boundary too. Nat.Riv Buff will exclude most of path. Where path isn't excluded: protect trail marker trees, limit areas where equip can cross, post warning signs prior to harvest, and protect the path in specs.
• Create clearcut patches around some of the scattered aspen clones. Use 2" spec inside patches.
• Retain underrepresented species (y.birch, elm, hemlock, b.cherry, xlog beech, wolf/den trees, etc.)
11) Seed Tree w/Retention. Residual avg. is flexible, aim for ~5-10BA.
• Maintain a 300ft Natural Rivers Buffer along the treatment’s southern boundary near the Jordan River. Rx layer accounts for this buffer. NCPathway is present within buffer, sign & protect in specs.
• Do Not run the east boundary right up to or downslope to the perennial stream. Boundary excluded retention and 'Water quality/BMP' site conditions already identified in east. Use additional retention to capture sensitive/unique features if observed.
• Leave a scattered seed source of desirable hardwood species. Wind firm individuals are present and/or leave in clumps. Residual BA can vary/doesn't have to be consistent throughout. Continued on next page.
• Mark to leave some larger beech & aspen to become future snag material
• Do not cut incidental species, including but not limited to: elm, y.birch, conifer, etc.
20A) Seed Tree w/Retention. Residual avg. is flexible, aim for ~5-10BA.
• Maintain a 300ft Natural Rivers Buffer along the treatment’s S.W. boundary near Section 13 Creek. Rx layer accounts for this buffer.
• Do Not run the north boundary right up to or downslope to Racket Creek in north.
• NCPathway travels along southern boundary. Use the pathway as the southern boundary, protect trail marker trees, only allow equip to cross the path in one location, use some retention near the path, post warning signs prior to harvest, and protect the path in specs.
• Use island/boundary excluded retention to capture sensitive features, desirable regen, etc. Some sugar maple regen already captured, see S.C. 5E-25.
• Leave a scattered seed source of desirable hardwood species. Wind firm individuals are present and/or leave in clumps. Residual BA can vary/doesn't have to be consistent throughout.
• Mark to leave some larger beech & aspen to become future snag material
• Do not cut incidental species, including but not limited to: elm, y.birch, conifer, etc.
20B) Crown Thinning. Target 80BA.
• Prep with Stand 21's crown thin
• Loosely use NCPathway as the boundary. This will negate incursions into adjacent water features. Back off the path as needed based upon topography. Protect trail marker trees, place warning signs prior to harvest, and protect path in specs.
• Retain underrepresented species (y.birch, elm, hemlock, b.cherry, xlog beech, wolf/den trees, etc.)
21) Crown Thin TSI to release crop trees & pole/sap stems. Target 80BA.
• 'Too steep' areas already excluded from Rx layer (S.C.2F-21). These might expand/contract during prep.
• Do Not run boundary right up to or downslope to Racket Creek
• Two stick nests observed in Rx area (see Arc/Comp map). Not sure if active. Protect/exclude as needed.
• NCPathway in Rx area. Protect trail marker trees, limit areas where equip can cross, post warning signs prior to harvest, and protect the path in specs.
• Retain underrepresented species (y.birch, elm, hemlock, b.cherry, xlog beech, wolf/den trees, etc.)
