Follow up Basal Area Cruise of Four Compartments Treated with Uneven-aged Management Group
Openings and Thinning Between Groups
Name: Mike Keeley
Job title: Resource Forester
Conservation Area: Apple Creek and Seventy Six Conservation Areas
Region / County: Southeast Region / Cape Girardeau and Perry Counties
Date of Observation: 12/2008
Community Type: Dry, Dry-mesic, and mesic oak and mixed hardwood forest hills in the OZ12w and
Management practices: UAM commercial timber harvest and follow up slashing of group openings and
timber stand improvement between groups.
Objective: Create group openings where advanced oak regeneration was present by harvesting mature
and undesirable saw timber. Leave areas without desirable regeneration and saw timber health could
make it at least another rotation. Create a mosaic of differing stand structures balancing forest health,
establish oak regeneration and aesthetics with whitetail deer, turkey, and squirrel habitat.
Apple Creek Compartment 2
East and west facing slopes with various micro-aspects. Site class 3 – 4. Dry Mesic Limestone Forest
mixed oak hickory – mixed hardwood. Generally a two-aged stands with saw timber of 90-110 years old
and pole small saw timber class of 50 years old. Data was collected on random cruise plots.
Stand # 58 Pre harvest basal area – 92 BA, Reduce to a desired level of 61 BA.
Present basal area range is 60 – 90 BA. Average for the stand is 77 BA following
Stand # 57 Pre harvest basal area – 108. Reduce to a desired level of 72 BA.
Present basal area range is 50 – 100 BA. Average for the stand is 71 BA following
Stand # 59 Pre harvest basal area range – 117 BA. 60 – 110 BA. Reduce to a desired level of 78 BA.
Present basal area range is 60 to 110 BA. Average for the stand is 90 BA following
Over all the average basal area for the compartment is 79 BA following treatments.
Apple Creek Compartment 3
South facing hillside with east/west micro aspects. Site Class 3. Dry – Dry Mesic Limestone Mixed oak-
hickory, Mixed hardwoods. Generally mature stand with trees from 100 to 150 years has not been
disturbed in the recent past.
Stand 11 Pre harvest basal area – 108 BA to be reduced to a desired level of 72 BA following
Present basal area range is 40 BA to 70 BA with an average of 58 BA following
treatments. Note: Basal area reduction is lower in compartment 3 because of the
condition of the over story that is composed of large diameter, declining black oaks.
Seventy-Six Compartment 5
West facing slope with some northwest/southwest micro aspects. Site Class 3. Dry Mesic Limestone.
Mixed oak-hickory, Mixed hardwoods. Generally undisturbed oak-hickory saw timber with sugar maple
Stand 1 Pre harvest basal area - 126 BA with a desired level of 84 BA following treatments.
Present basal area range is 80 BA to 140 BA with an average of 104 BA following
Seventy-Six Compartment 3
This is a Northeast facing slope of loess soil supporting mesic mixed hardwoods that is a good example
of a Site Class 4 forest community. Uneven age treatment was completed 20 years prior. The stand
consists of a mix of retained mature and immature oak 100-150 year old saw timber and large pole-
small saw timber size yellow poplar, sugar maple, hickory, and ash. The older white oaks are scattered
through the stand of yellow poplar.
Stand 1 Pre harvest basal area was 80 BA to be thinned to a desired level of 57 BA.
Present basal area range is 40 BA to 90 BA with an average basal area of 67 BA following
Stand 3 Pre harvest basal area was 94 BA to be thinned to a desired level of 69 BA.
Present basal area range is 60 BA to 100 BA with an average of 78 BA following
Overall Structure and condition of multiple age classes seemed acceptable given the condition of the
preexisting stand and reentry timing. Except for Seventy-Six CA Compartment 5 too much pole sapling
sugar maple is in the understory for oak recruitment. The follow up TSI needs to be heavier. Also oak
regeneration issues were noted on high site classes of 76 Comp 3 during the inventory cruise and is
related to the presence of paw-paw and spice bush sapling layer of shade that does not get represented
in the prism cruise and is difficult to treat in our standard TSI practices. Consideration should be given
to thin-line or mist spray of herbicide as budgets and time allow.
