Harvest planning is typically done in two distinct steps, namely strategic harvest planning and operational harvest planning. Strategic harvest planning is performed over large areas (whole property) and long time periods (10 years plus). The purpose of a strategic harvest plan is to specify all management activities (including harvest scheduling), in order to reach pre-defined volume, revenue, operational area or investment targets for the whole property. At FSI we have developed various Linear Programming models in the GAMS environment that allow us too quickly and accurately perform this type of planning.
The second step in harvest planning is operational planning. This type of planning is much more focused, and typically deals with the operational activities associated with a specific stand of trees within a planning period (one year). The purpose of this type of planning is to anticipate and mitigate all the operational obstacles that could be encountered during the harvest process, and to maximize the efficiency of the overall operation. Factors considered during operational harvest planning include terrain, slope, erosion, harvest system, harvest equipment, extraction distance, tree size, stand density, road requirements and infield processing. The product of such a planning exercise is typically a written harvest plan, including maps that illustrate the layout of the harvesting operation given the site constraints and considerations. Our knowledge of operational harvest planning comes from the local, national and international levels. Our employees have experience from Asia and the Pacific.
The combination of specialized harvesting equipment allowing for the harvesting process, from stump to mill, is known as a harvesting system. The following are some of the harvesting systems we have experience with here at Forest Solutions, Inc.
• Cut-to-Length system
• Combination of a Harvester, forwarder, loader, and hauling
• Mechanized ground-based system
• Combination of a mechanical harvesting machine, skidder, loader, and hauling
• Manual ground-based system
• Combination of chainsaw, skidder, loader, and hauling
• In-woods chipping system
• Farm tractor harvesting systems
• Cable logging systems
• Helicopter logging
During the harvest planning stage we review potential harvesting systems in-order to meet the site-specific and wood market demands of the forest. For example, we evaluate whether wheeled or tracked machines are best. We will find the best system that is efficient, reduces costs, and maximizes log value recovery.
Harvest Road Planning
Our goal is to ensure roads, water crossings, and any related infrastructure are fit for purpose and meet the highest environmental standards. Road building comes at a very high cost to landowners, so we implement the most cost-effective planning tools and infrastructure available. We use ArcMap GIS software to aid in choosing the best location of infrastructure and combine computer software and field survey’s to complete road design. Our experience includes building road infrastructure in both plantation and natural forest settings here in Hawaii and abroad.
