NEWBERRY FOREST MANAGEMENT UNIT COMPARTMENT REVIEW PRESENTATION
COMPARTMENT # 10 ENTRY YEAR: 2011 Y.O.E.
Compartment Acreage: 2210 Acres (GIS Calculated) County: Luce
Revision Date: 9/16/2009 Stand Examiner: Keith Magnusson Legal Description: T48N R11W Sec. 7, 16-20, 28-30, 32, 33 T48N R12W Sec. 10, 11, 14, 15 RMU (if applicable): Management Goals: Wildlife, timber, and recreation are the main uses of this area. The goal is to manage for all of these simultaneously and to provide, enhance and perpetuate their uses through proper management. Forest treatments prescribed will help ensure the sustainability of the forest resource and continue to enhance the quality of the wildlife habitat. Soil and Topography: Topography is variable throughout the compartment with a complex of uplands and lowlands. The soils are mostly complexes as well due to the upland and lowland nature of the landscape. Most of the uplands are dominated by beech-maple-hemlock, white pine-hemlock forest types where the topography is level to rolling with steep ridges mixed throughout and the major soil types are Wallace, Paquin, Rubicon and AuGres. The lowland areas are relatively level and dominated by mixed conifer swamp and shrub/emergent marsh cover types. They mostly consist of soil complexes such as Tawas/Spot/Finch, Carbondale/Lupton/Tawas and Dawson/Greenwood/Loxely. Ownership Patterns, Development, and Land Use in and Around the Compartment: The compartment lies to the west of Pine Stump Junction. The West Branch of the Two Hearted River is the northern boundary and the South Branch of the Two Hearted River is the east boundary of the compartment. This compartment is made up of broken State ownership surrounded mainly by Nature Conservancy Lands as well as some Heartwood Forestland property. There is some individually owned private land scattered throughout the compartment as well. The compartment is within the Two Hearted River Watershed. Predominate land use in the area is mostly involves timber production and recreation such as hunting, fishing, dispersed camping, ORV and snowmobile riding, dog sledding and wildlife/nature viewing. Unique, Natural Features (include only non-site specific and non-sensitive information): Unique features of the compartment would be the watershed of the Two Hearted River and its corridors as well as the Two Hearted Lakes Complex. Michigan Natural Features Inventory (MNFI) identified the compartment as containing natural communities of hardwood-conifer swamp and muskeg. Within these communities MNFI lists the potential for red-shouldered hawk, goshawk, merlin, great blue heron rookery, black-backed woodpecker, spruce grouse, eagle, and osprey. Potential for moose and wolf. Potential for incurvate emerald, frigga fritillary, freija fritillary, and ebony boghaunter in boggy areas. Potential for wood turtle. Potential for loon in lakes. They also list the potential for sweet coltsfoot, Wiegand's sedge, northern prostrate clubmoss, fir clubmoss, English sundew, meadow beauty, round-leaved orchis, black crowberry,
yellow pitcher plant, and panicled screwstem in bogs and open wetlands. Potential for calypso orchis, lapland buttercup, ram's head lady's slipper, round-leaved orchid and limestone oak fern in cedar swamps. Archeological, Historical, and Cultural Features (include only non-site specific and non-sensitive information): The Bureau of History does not list any historical features. Special Management Designations or Considerations: The hemlock and white pine ridges that run between the Two-Hearted Lakes are a very unique feature in this compartment. Also, follow guidelines described in the Two-Hearted River Natural River Plan while prescribing management activities near the natural river zone. Watershed and Fisheries Considerations: Fisheries Values Excellent. The S. Br. Two-Hearted River, FQCW, flows north through the eastern side of this compartment, providing excellent native brook trout fishing. Jack Creek is also classified FQCW, while Dairy Creek is SQCW, both supporting good populations of native brook trout. In addition, Dairy, Jack, Whorl and Little Whorl Lakes all contain native brook trout as well. Wildlife Habitat Considerations: Compartment 10 lies in northwestern Luce County and is in the Seney Sand Lake Plain ecological sub-subsection. The west branch of the Two-Hearted River makes up portions of the northern boundary of the compartment and the Little Two-Hearted Lakes are within the compartment. The compartment is intermixed with large portions of Nature Conservancy ownership and is a mix of mature hardwood, lowland conifer types, and bogs and marshes. Wildlife objectives for this compartment will be met by maintaining species diversity in harvested stands including retaining conifers in thinned hardwood stands. Soft mast species will be retained as will some good quality potential raptor nest trees. Interspersion of harvested stands will ensure that travel corridors for wildlife will remain intact. Marshes will be buffered and low ground leatherleaf areas will be avoided during harvest to preserve wetland wildlife values and habitats. White-tailed deer, black bear, moose, marten, grouse and otter and mink are species expected to inhabit this compartment. Mineral Resource and Development Concerns and/or Restrictions: Sections 16 – 20 & 28 - 33, T48N-R11W & Sections 10 - 15, T48N-R12W, Luce County Surface sediments consist of lacustrine (lake) sand and gravel and peat and muck. There is insufficient data to determine the glacial drift thickness. The Ordovician Black River and Prairie du Chien (PdC) Groups and Cambrian Trempealeau Formation subcrop below the glacial drift. The Black River is quarried for dolostone in the UP and the PdC and Trempealeau could be used for stone. Gravel pits are not located in the area, but there may be some potential. There is no economic oil and gas production in the UP. Vehicle Access: The main access to the compartment via the CCI Road. There are several unnamed two tracks that lead into various parts of the compartment. Most if not all of the roads in this compartment were created by past logging activities on both State and private land. Currently some of these roads are only passable by 4-wheel drive vehicle and many of them are not well traveled. Because of this some roads have become abandoned and overgrown with trees making areas of the compartment relatively remote and difficult to access by vehicle. Survey Needs: Need additional survey corners in Sections 16, 17 and 18 pertaining to the treatments prescribed (see compartment map). Recreational Facilities and Opportunities: The CCI Road serves as a DNR designated snowmobile trail during the winter months. Other recreational opportunities in and near this compartment would be hunting, fishing, trapping, ORV riding and wildlife viewing. In the fall this area is typically hunted heavily for bear.
Fire Protection: The compartment is partially in the Two Hearted Zone Dispatch area. Large fire runs are not likely but possible because of the scattered lowland area and cover types not typical of large fire runs. Fire suppression will be difficult in some areas because of poor heavy wheeled equipment access and remoteness. Private properties risk would be moderate to low. Additional Compartment Information:

NEWBERRY FOREST MGT UNIT Compartment: 10Proposed Treatments With NO Limiting Factors
Entry Year: 2001
4 M9 56 55 unevenaged delayed removal 3northern hardwood
Stand was treated in 1965 T.Sale#050-64. It is now large hardwood trees overtopping abundant sapling sized hardwood reproduction. Some hemlock and white pine present. The beech in here has been severely impacrted by beech bark disease, many dead standing snags and dying trees. Quality of the standing timber is not that great because the trees are overmature and defective. If scheduled, remove some of the overstory to release the existing regen. A portion of this stand falls within the Two Hearted Natural river zone, follow plan if stand is treated. Access across TNC land would be needed if stand is treated.

* This is a list of Dedicated Biodiversity Areas for this compartment along with a 1/4 mile buffer surrounding the compartment. Refer to Dedicated Conservation Area Map for areas that the below listed Conservation Areas are located.
DEDICATED CONSERVATION AREA DETAILS
Conservation Area SCA = Special Conservation Area
HCVA = High Conservation Value AreaERA = Ecological Reference Area
Ecological Reference Areas (ERAs) are high quality examples of natural communities that have been identified as Element Occurrences (EOs) by the Michigan Natural Features Inventory (MNFI) within the context of their natural community classification system. Element Occurrences with viability ranks of A (Excellent) or B (Good) and a Global (G) or State (S) element (rarity) ranking of endangered (1), threatened (2), or rare (3) serve as an initial base of ERAs. They may be located upon any ownership in the State. The system is comprised of individual or associations of natural community types that are managed for restoration and maintenance of natural ecological processes and values. The public may submit recommendations for lands as ERAs using the DNR Conservation Area Recommendation Form.
Ecological Reference Areas
ERA
There are two Natural Rivers datasets which are derived from spatial buffers set from an established and approved distance from the river centerlines. The Natural Rivers Zoning District is a 400 foot buffer for most Natural Rivers. The Vegetative Buffer ranges from 25 to 100 feet. To view specific Zoning Districts and Vegetative Buffers for each Natural River see the table located on the I:\Documentation\GDSE data folder.
Natural RiversHCVA
A coldwater lake has temperature and dissolved oxygen conditions that allow naturally-reproduced or stocked trout populations and those of other coldwater fish species to persist from year to year. Suitable conditions for coldwater fishes may occur in Michigan lakes if they are relatively deep, have substantial groundwater inflows, or are located in colder (northern) areas of the state. Such lakes are established by Director's action and designated as trout resources by Fisheries Order 200.
Cold Water LakeSCA
A coldwater stream has temperature and dissolved oxygen conditions that allow naturally-reproduced or stocked trout populations and those of other coldwater fish species (e.g., slimy sculpin) to persist from year to year. Coldwater streams in Michigan typically provide these conditions due to substantial contributions of groundwater to their stream flows. Such streams are established by Director's action and designated as trout resources by Fisheries Order 210.

SCA
This category contains stands were identified for a broad range of reasons and were coded in the OI database as stand condition 8 as potential old growth (POG). Approximately 310,000 acres have been identified through the Operations Inventory (OI)/Compartment Review process. For stands in Year of Entry 2008 and forward, potential old growth is managed for the identified objective until it is: 1) vetted through the Biodiversity Conservation Planning Process (BCPP) and given a specific designation and objective (as an ERA, HCVA, or other type of SCA) and is released from the potential old growth designation; or 2) it is released from the potential old growth designation via the Compartment Review process.
