How We Harvest

A.   Equipment

The Harvester will fall, de-limb the trees and stack trees, while the Skidder pulls bunches to the roadside or landing. A self-loading truck will load logs, transport and unload in larger decks. A knife chipper will process logs into usable product. The harvester is a Hitachi ZX200 with Waratah 622 processor head seen on the right (Figure 1).

A highly efficient machine capable of effectively falling trees between 4″ and 22″ diameter. A John Deere 748G skidder with front blade and grapple will be able to assist in field transportation, limited route clearing a potentially be configured to perform necessary scarification measures (Figure 2).

A recently acquired self-loading truck will introduce several functions of that increase efficiency, such as organized loading and unloading, create taller deck stacks, maneuver and transport material for processing (Figure 3).

Capable of hauling 20+ ton load.the rig can accommodate logs 20-40 in length. the Bandit knife chipper can process a maximum of 14″ diameter logs with a small feed-grapple and extended rear-delivery chute    (Figure 4).

A lease or contractor agreement will be developed for other necessary equipment or harvest functions, like constructing access routes. A dozer will be used for sheering stumps, leaving soil, and positioning, smoothing or compacting accumulated snow. An excavator may be required for trails that need transect areas consisting of larger diameter stumps and deeper root systems.

C.    Harvest Practices

Best Management Practices (BMPs) will need to mitigate ecological impacts of
harvest, apply appropriate reforestation activities and attempt to enhance conditions for a variety of forest values. SEGA intends to implement positive-impact logging strategies that will compliment disciplined monitoring and adherence to recognized protocols and regulations (i.e., the Alaska Forest Resources & Practices Act 2013 with 2015 amendments). These actions revolve around five critical functions, including; a) reduce physical effects of logging equipment, b) mitigate effects on residual trees, c) establish procedures that eliminate environmental impacts of pollution, d) avoid creating conditions that promote the unpredictable impacts of invasive species and e) carefully consider areas of harvest, in order to decrease the potential effects of fragmentation.

All extraction activities will take place during the winter, in order to protect ground vegetation and reduce exposure of mineral soil. Entrance to harvest units will begin when soil frost depth meets or exceeds 6″ or when snow accumulation provides adequate load bearing capacity (8-12″). The wide-footprint and tracked-wheels of the harvester, accompanied by wide tires the skidder, reduce ground pressure and soil compaction.



D.     Harvest Operations

SEGA has obtained permission to cross State Department of Transportation Airport property, in order to access GYL lands. With minor widening completed, these routes will serve as future entry and exit points.through discusstion and consideration of initial harvest locations have led to the decision that the training session and extraction of two years biomass be performed in the southwestern portion of this sale area.

Approximately 25 acres of poplar stands are dispersed in narrow swaths 1.4 acres in size. one mile of winter road will need to be constructed to access these units. An additional mile and a half may need  to be placed. pending the results of scheduled hround truth timber cruises of the remaining volume needed. An areial and map reconnaissance suggests sufficient volume in the 170 acre parcel further north, which could bring the total forest route distance to two and a half miles for the initial harvest season. Under this scenario, the furthest transport distance is approximately 4 miles.
