Specifications include, but are not limited to: Approximately 30,000 lb excavator or similar size wheeled/tracked machine equipped with masticator, chipper or equivalent processor capable of thinning advanced regeneration and rearranging vegetative fuels.
Minimum Tree Height to masticate – 2 feet
Maximum Tree Diameter (at DBH) to masticate – 7” DBH
75% of debris/chips from masticating must be <3’ in length, 25% of debris/chips from masticating may be >3’ in length. All debris/chips must be < 1’ in height/depth
All mastication debris shall be kept within the PCT treatment units or adjacent commercial harvest units. Debris must be kept off roadways.
Pre-Commercial Thinning Specifications:
Reduce densely stocked PCT units to stocking levels equivalent to a 20’-25’ spacing between leave trees. It is acceptable to leave closely spaced doubles/triples to create a more natural looking stand so long as selected leave trees are of good form, vigor and species preference. Target stocking post-treatment should be approximately 70-110 trees per acre.
