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.
