Example Cruise Plan 2
1. Marking Guidelines A. The following marking guidelines are for all Hardwood Clearcut w/Reserves units:
• Target Basal Area (outside of reserve trees/groups)= 0 ft2 /acre
• 7-10% of stand will be left in reserve trees/groups Determination of Reserve Trees/Groups
1. Reserve trees should be composed primarily of the largest, long-lived species on site (Pine, White
Oak, Post oak, Hickory, Black gum and if necessary, black &/scarlet oak).
2. Reserve trees should be grouped or retained around larger snags, large live trees, cavity or den trees, and within intermittent drainages.
3. Reserve trees should be left in groups of at least five or more trees wherever possible.
4. Space reserve trees/groups to mimic natural community structure and composition.
5. Retain some fruit-bearing trees when possible.
B. The following marking guidelines are for all Hardwood Shelterwood w/Reserves units:
• Target Basal Area (outside of reserve trees/groups) — 20-30 ft2 /acre Determination of shelter (leave) trees:
1. Healthiest white oak, red oak, post oak, black oak and hickory
2. Over mature trees (generally 24”+ dbh) should be considered for removal if not a wildlife tree
3. Correct spacing
• 7-10% of stand will be left in reserve trees/groups Determination of Reserve Trees/Groups
1. Reserve trees should be composed primarily of the largest, long-lived species on site (Pine, White
Oak, Post oak, Hickory, Black gum and if necessary, black &/scarlet oak).
2. Reserve trees should be grouped or retained around larger snags, large live trees, cavity or den trees, and within intermittent drainages.
3. Reserve trees should be left in groups of at least five or more trees wherever possible.
5. Retain some fruit-bearing trees when possible.
C. The following Marking guidelines are for all Hardwood Open Woodland Thinning units:
• Target Basal Area – 30-50 ft2 /acre Determination of leave trees
1. Healthiest mast producing trees
2. Key on removing stressed, suppressed, diseased, & bug infested trees
D. The following Marking guidelines are for all Hardwood Thinning units:
• Target Basal Area —50-80 ft2 /acre
• Target Spacing — Approx. 20-50 feet, but optimum/average spacing between trees depends on avg. stand DBH- look at spacing guidelines on last page of this Cruise Plan Determination of leave trees
1. Trees of more desirable species (oaks, ash, cherry, walnut, hickory)
2. Trees of best form and crown development
3. Correct spacing
E. The following Marking guidelines are for all Hardwood Salvage units:
• Mark all commercial Red Oak/Black Oak trees that have symptoms of oak decline, do not mark any other tree species.
F. The following marking guidelines are for all Pine Clearcut w/Reserves units:
• Target Basal Area (outside of reserve trees/groups)= 0 ft2 /acre
• 7-10% of stand will be left in reserve trees/groups Determination of Reserve Trees/Groups
1. Reserve trees should be composed primarily of the largest, long-lived species on site (Pine, White
Oak, Post oak, Hickory, Black gum and if necessary, black &/scarlet oak).
2. Reserve trees should be grouped or retained around larger snags, large live trees, cavity or den trees, and within intermittent drainages.
3. Reserve trees should be left in groups of at least five or more trees wherever possible.
4. Space reserve trees/groups to mimic natural community structure and composition.
5. Retain some fruit-bearing trees when possible.
6.
G. The following marking guidelines are for all Pine Seedtree w/Reserves units:
• Target Basal Area (outside of reserve trees/groups)= 10-20 ft2 /Ac Determination of seed (leave) trees:
1. Shortleaf pine that are vigorous, cone bearing, well developed, and straight boled
2. Over mature trees (generally 24”+ dbh) should be considered for removal if not a wildlife tree
3. Correct spacing
4. Remove all hardwood from stand except where needed for wildlife or to meet minimum BA
• 7-10% of stand will be left in reserve trees/groups Determination of Reserve Trees/Groups
1. Reserve trees should be composed primarily of the largest, long-lived species on site (Pine, White Oak, Post oak, Hickory, Black gum and if necessary, black &/scarlet oak).
2. Reserve trees should be grouped or retained around larger snags, large live trees, cavity or den trees, and within intermittent drainages.
3. Reserve trees should be left in groups of at least five or more trees wherever possible.
H. The following marking guidelines are for the Pine Open Woodland Thinning units:
• Target Total Basal Area —30-50 ft2/Acre
• Target Pine Spacing —optimum/average depends on avg. stand DBH- look at spacing guidelines on last page of this prescription.
Determination of pine leave trees
1. Trees of more desirable species (shortleaf, white oak, post oak)
I. The following marking guidelines are for all Pine Thinning units:
• Target Total Basal Area — 60 to 80 ft2/acre
• Target Pine Spacing —Optimum/average depends on avg. stand DBH- look at spacing guidelines on last page of this prescription.
Determination of pine leave trees
1. Trees of more desirable species (shortleaf, oaks, hickory)

1/ A minimum tree must include atleast one piece that meets minimum specs. As one can see from above specs, there is an overlap of specs for Posts andPulpwood/Fuelwood. Pine and Hardwood trees 9.0" - 10.99" DBH may be sold as posts or as pulpwood depending on local markets.
2/ Plus trim allowance
3/ 90% applies to rot, voids, and char. Mechanical type defects such as sweep, crook, spider heart, and ring shake shall not be considered as deductions for soundness.
4/ Reasonably straight is when the true center line of a minimum length piece does not deviate more than one-half the inside diamter of the small end, plus one inch from a straight line drawn between the centers of the ends of the piece.
