Area Control Framework — Annual Harvest Scheduling by Stand Type
The Timberland Investor
Area control basics
- What is area control?
- Area control regulates harvest by acreage rather than volume. If you want a 60-year rotation, you can sustainably harvest 1/60th of your forest each year — ensuring the first areas cut will be ready again by the time you complete a full cycle.
- Why not volume control?
- Volume control tries to match annual harvest to annual growth, but both are difficult to measure accurately, making error more likely. Area control is simpler and more reliable for long-term sustainability.
- Harvest interval
- How often you plan to enter a stand for harvest. A 10-year interval means each block of acres gets cut every 10 years. Shorter intervals suit intensive management; longer suits low-impact or wildlife objectives.
Setting up stand types
- Stand type
- Group your forest by species composition, age class, or management objective. Classifications can be as broad or specific as your needs require.
- Target age
- The age at which you plan final harvest. Choose based on your goals — maximum volume production, wildlife habitat, or financial return.
- Volume per acre
- Expected yield at target age. Use your own inventory data or the Forest Growth Tool to estimate. Works in Cords, Tons, or MBF — stay consistent within a stand type.
- Even-aged vs. uneven-aged
- Even-aged: Regeneration harvest removes most trees; stand re-establishes from scratch. Add intermediate thinnings at specific years if planned.
Uneven-aged: Selection system — a percentage of standing volume is removed each entry, maintaining continuous canopy cover.
Reading the outputs
- Acres per harvest
- Total acres divided by rotation periods (target age ÷ interval). This is how many acres you can sustainably cut each entry while maintaining your desired age structure.
- Annual equivalents
- Per-harvest figures divided by the interval length. Useful for comparing stands on a common annual basis and planning contractor capacity.
- Timeline
- Shows harvest events at their computed years across a 30-year window. Stands are staggered to avoid concentrating all logging in the same year. Hover a cell for details.
- Small parcels
- Area control is less effective on smaller properties. If acres-per-harvest falls below practical logging minimums (~5 ac), consider adjusting your harvest interval to match logistical realities.
