challenges with regenerating chipper debris pads: evaluating seedling performance nine years after planting
abstract
debris from in-bush portable chain flail chippers can alter the abiotic
environment factors within the mineral soil. thus, chipper debris can create an
unsuitable seedbed for seedling growth and survival. in this thesis, jack pine and white
spruce will be planted on fresh chip pads (age=2) and chip pads that had time to
decompose (age=9). previous research has shown that chipper debris can insulate the
soil, repel or maintain moisture based on the age of debris, and leach toxic material
based on the age of debris. ensuring that chipper debris pads are regenerating with
merchantable species is important for forest managers to maintain productivity on crown
land.
