What you will learn
- What a harvest plan must balance: volume, access, environment and demand
- How stands are sequenced over months and years
- How roads, landings and haul routes constrain the plan
- How environmental limits are built into planning, not added afterwards
- Where harvest planning ends and harvesting operations begin
What this project is
Harvesting is not just cutting trees. A plan must choose which stands to harvest, in what sequence, so that mills receive the right species and volumes at the right times, while roads and landings can handle the traffic, and environmental limits, such as buffers along streams, nesting seasons and soil protection, are respected. A planning system holds the inventory, the road network, the environmental constraints and mill demand together, and builds a plan that balances them.
Sequencing matters. Harvesting one stand may open access to the next, or may block it. Cutting a stand in wet season may damage soil that a dry-season harvest would not. A plan that ignores those interactions creates problems that field crews must solve under pressure. The system should let planners test sequences, see the volume and road implications of each, and adjust before the plan reaches the field.
Core features
- Stand selection and sequencing against inventory, age and readiness
- Road and landing planning, with haul routes and access constraints
- Environmental constraint mapping: buffers, protected areas, seasonal restrictions
- Volume and species forecasting against mill demand by period
- Plan versions and comparisons, so a revised plan can be measured against the original
- Field outputs: harvest maps and coupe plans for crews and contractors
How it is built
- Start with inventory, roads and constraints, because the plan is only as good as those inputs
- Build stand sequencing and volume forecasting, then road and landing planning
- Add environmental constraints as hard limits in the planner, not as notes
- Add plan versioning and field outputs, then test a plan with field crews before full adoption
- Pilot on one forest block for one season, comparing planned versus actual volumes and road use
Technology considerations
Constraint handling is the technical core. Environmental buffers, seasonal restrictions and road capacities are not suggestions; the planner should treat them as constraints that a plan cannot violate without an explicit, recorded exception. That requires spatial data that is accurate: a buffer drawn in the wrong place protects the wrong stream. Road planning needs the same accuracy: a haul route that looks fine on a map may be impassable in wet weather, and the system should record road condition and seasonal access, not just road existence.
Volume forecasting needs to be honest about inventory uncertainty. If stand volumes are estimates, the plan's volumes are estimates too, and the system should show the basis for each figure. Integration with mill demand matters: a plan that produces the wrong species mix, however efficiently, fails its purpose. Demand should be entered by period and species, and the plan should show shortfalls plainly.
For the first version, plan one forest block for one season: stand sequence, volumes against mill demand, road use and environmental constraints as hard limits. Harvest managers judge the plan on whether field crews can execute it without discovering blocked access or breached buffers. A plan that works for one block, with versions recorded, earns the confidence to plan the whole forest the same way.
Challenges to plan for
- A plan that produces the right total volume but the wrong species mix for the mills
- Roads that cannot carry the planned traffic in wet conditions
- Environmental constraints discovered in the field, after the plan is issued
- Stands sequenced in an order that blocks access to the next stand
Who it is for, and its limits
This suits a forestry company, a forest manager or a harvesting contractor planning at scale. It fits forests where several stands, roads and mills must be coordinated. It does not fit a single-stand harvest where the plan is obvious, and it is not a harvesting machine control system: it plans the harvest, it does not operate the machines.
A harvest plan does not cut trees. It makes the cutting order, road use and environmental compliance planned rather than improvised. Costs vary with forest size and constraint complexity, so confirm with a quote after the inventory and roads are mapped.
Frequently asked questions
How are stands chosen for harvest?
By readiness from the inventory, mill demand for their species and volume, road access, and environmental constraints. The planner weighs those together, rather than picking the nearest or easiest stand.
What are environmental constraints in planning?
Buffers along waterways, protected areas, nesting or breeding seasons, and soil protection rules. They are built into the planner as limits, so a plan that violates them is flagged before it reaches the field.
How are roads planned?
From the road network, landing locations and haul routes, with seasonal access and capacity recorded. A plan that needs a road that cannot carry the traffic is revised before crews arrive.
Can a plan change mid-season?
Yes, with versioning. A revised plan is recorded as a new version, so field crews always know which plan is current and past decisions can be traced.
Does the system control harvesting machines?
No. It produces maps and coupe plans for crews and contractors. Machine guidance, where used, is a separate system that reads the plan.
