About this file
This document provides marking instructions and cruise design details for multiple timber sales on the Ottawa National Forest in Michigan. The sales involve a variety of treatment units including hardwood selection, aspen clearcuts, commercial thinning, shelterwood cuts, and right-of-way clearings. Product types encompass various pulpwood and sawtimber grades of aspen, mixed hardwoods, red pine, white pine, and other species. Cruise design sample groups are defined by species, diameter ranges, and sampling intervals. Minimum tree and piece specifications are also outlined. Contractors will be responsible for marking designated trees according to instructions for each payment unit, and cruising the marked trees to determine volumes. The solitation is for marking and cruising services on multiple timber sales with a combined estimated value of over $1.4 million. The response due date and award information are not provided.

Instructions
Payment Unit 2-9 & 12– Hardwood Selection/Sample Tree Cruising (STR) – ALL merchantable trees to be removed from this Payment Unit require two paint marks at DBH on opposite sides of the tree AND a corresponding stump mark (see specific Marking Instructions for this Payment Unit). Cruise marked trees using the Sample Groups and Sample Intervals below.
Payment Units 10 & 11- Aspen Clearcut/Sample Tree Cruising (STR)
ALL merchantable trees within these Payment Units are designated for removal EXCEPT hemlock, cedar, white and red pine (which are designated leave tree species) AND Leave Trees (LTs).
Merchantable trees (except hemlock, cedar, white and red pine) to be removed from these Payment Units only require a paint mark at DBH to verify the tree has been counted; a stump mark is not required. Designated leave species (hemlock, cedar, white and red pine) require a paint mark at DBH AND at the stump only when chosen for removal (operability, disease/insect, or other conditions that may be described in the Marking Guides). Any and all LT’s will be marked by USFS. LT’s are to be marked with a single orange band at DBH, and a corresponding orange stump mark. As stated in the “REMARKS” and “MARKING GUIDE” section, no lone Elm or Oak are too be left. LT’s will need to be marked around the lone oak or elm, if not a designated leave species. LT’s may also include healthy groups of hardwoods as stated in the Marking Guides. All banded LT’s are to be counted and recorded by species and by payment unit during the cruise, preferably with provided Leave Tree Form and turned in with Tally Cards for each payment unit. (see specific Marking Instructions for these Payment Units) Cruise marked trees using the Sample Groups and Sample Intervals below.

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)

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.

Payment Units 8 & 9- Aspen Clearcut/Sample Tree Cruising (STR)
ALL merchantable trees within these Payment Units are designated for removal EXCEPT hemlock, cedar, white and red pine (which are designated leave tree species) AND Leave Trees (LTs).
Merchantable trees (except hemlock, cedar, white and red pine) to be removed from these Payment Units only require a paint mark at DBH to verify the tree has been counted; a stump mark is not required. Designated leave species (hemlock, cedar, white and red pine) require a paint mark at DBH AND at the stump only when chosen for removal (operability, disease/insect, or other conditions that may be described in the Marking Guides). Contractor will mark Leave Trees in PU 8 & 9 at the rate of 2-3 healthy trees per acre of either paper birch and/or northern red oak, depending on availability. LT’s are to be marked with a single orange band at DBH, and a corresponding orange stump mark. As stated in the “REMARKS” and “MARKING GUIDE” section, no lone Elm or Oak are too be left. LT’s will need to be marked around the lone oak or elm, if not a designated leave species.
LT’s may also include healthy groups of hardwoods as stated in the Marking Guides. All banded LT’s are to be counted and recorded by species and by payment unit during the cruise, preferably with provided Leave Tree Form and turned in with Tally Cards for each payment unit. (see specific Marking Instructions for these Payment Units) Cruise marked trees using the Sample Groups and Sample Intervals below.
Payment Units 10 : Red Pine Thinning/Sample Tree Cruising (STR) ALL merchantable trees to be removed from this Payment Unit require two paint marks at DBH on opposite sides of the tree AND a corresponding stump mark (see specific Marking Instructions for this Payment Unit).

Any and all LT’s will be marked by USFS. LT’s are to be marked with a single orange band at DBH, and a corresponding orange stump mark. LT’s may also include healthy groups of hardwoods as stated in the Marking Guides. All banded LT’s are to be counted and recorded by species and by payment unit during the cruise, preferably with provided Leave Tree Form and turned in with Tally Cards for each payment unit.
