Abstract: A silvicultural tillage method and apparatus defines access corridors, infiltration zones, and debris filter zones to reduce the environmental insult to a forestry site during tillage and subsequent treatment of a crop tree stand. An articulating blade coupled to a prime mover clears ground debris from a forestry site to define the access corridors and debris filter zones. A tillage gang, incorporating a plurality of star shaped tillage blades is drawn by the prime mover and provides an infiltration zone in which to plant and cultivate the crop trees. The infiltration zone absorbs rain water runoff and particles suspended therein, and providing a water storage reservoir. The access corridors permit narrow band application of fertilizers and herbicides to the infiltration zones, while the preservation of natural vegetative cover within a portion of access corridor and the debris filter zones preserves the natural erosion preventive characteristics of the site.
