Timber management cutting and harvesting specifications

Timber management cutting and harvesting specifications. (1) Permit. (a) Permit issuance. No person may cut or harvest timber within the riverway without a permit issued by the riverway board. (b) Permit conditions. The riverway board shall place conditions in permits necessary to assure timber harvest or cutting is conducted in compliance with this chapter. Additional conditions, as applicable, shall be included but not be limited to: 1. Cutting specifications to insure that trees of desirable species and form be retained on the site after cutting. 2. Roads constructed for the purpose of harvesting timber shall be visually inconspicuous from the river during the time when the leaves are on the deciduous trees. 3. Timber cutting or harvesting is limited to those times when the ground is frozen or dry and the leaves are off the deciduous trees. 4. Erosion bars or culverts will be installed as necessary to prevent erosion. 5. Harvesting practices shall conform with the “Silvicultural and Forest Aesthetics Handbook” and the department publication “Forest aesthetics.” 6. Timber harvesting restrictions necessary to minimize the impact on any known populations of federally or state designated threatened and endangered species. (c) Maps or diagrams. Landowners desiring to conduct any timber cutting or harvesting, including road construction shall submit a map or diagram of the proposed timber harvest area identifying the property boundaries, harvest boundaries, road locations and other information requested by the riverway board or county. (2) Bluff zone, riverview zone and river edge zone. In addition to other restrictions established on timber cutting and harvest within the bluff zone, riverview zone and river edge zone, the following conditions shall be included but not be limited to: (a) No timber cutting or harvest may be conducted at any time other than when the ground is frozen or dry and the leaves are off the deciduous trees. (b) Road construction for the purpose of harvesting or cutting timber on slopes facing the river shall comply with the following: 1. The permit authorizing the timber harvest and road construction. 2. The average grade may not exceed a 10% slope. 3. Grades up to but not exceeding 15% for no longer than 75 feet horizontal distance are authorized; however, grades with a slope of 10% to 15% may not constitute more than 20% of the road length. 4. Road width may not exceed 12 feet. 5. Switchbacks are not permitted on slopes facing the river. However, a variance may be granted allowing switchbacks or grades in excess of the limits established in subds. 2. and 3. in areas that would otherwise be inaccessible subject to the visually inconspicuous requirement of sub. (1) (b) 2. and the erosion protection requirement of sub. (1) (b) 4. 6. Roads, upon completion of the timber cutting and harvest operation, shall be seeded to establish sod or other vegetative cover. (4) Bluff zone and river edge zone. No person may cut, harvest or remove timber within the bluff zone and river edge zone except by selection cutting. After cutting, the residual stand shall be at least 60 square feet basal area. (5) Riverview zone. No person may cut, harvest or remove timber within the riverview zone except as follows: (a) By small regeneration cuts with boundaries designed to harmonize with naturally occurring shapes consistent with the “Silvicultural and Forest Aesthetic Handbook” and the publication “Forest aesthetics;” (b) By shelterwood cuts not to exceed the size, shape, spacing or timing of regeneration cuts; (c) By selection cutting leaving a residual timber stand of at least 60 square feet basal area. (6) Resource management zone. Persons in the resource management zone are encouraged to conduct timber cutting, harvest or removal operations consistent with these rules and subch. IV of ch. 30 , Stats. The harvest and harvest method should consider integration of all resource capabilities, including: (a) Cutting boundaries should be designed to harmonize with the natural occurring shapes in the area.
