152. In a piling area, a forest operations zone having an area less than 4 ha or in any portion in a single block of 4 ha or more included in a forest operations zone, the volume of usable ligneous matter left on the ground or not harvested that exceeds 3.5 m3/ha in the case of a total cutting or that exceeds 1 m3/ha in the case of a partial cutting must be recovered on each of those areas before 1 September following the harvest year.
Where the sylvicultural prescription associated to the treatment to be carried out provides for a recovery standard different from that provided for in the first paragraph for the purposes of maintaining biodiversity, the threshold above which the volume of usable ligneous matter left on the ground or not harvested must be recovered is that provided for in the sylvicultural prescription.
For the purposes of this section, the volumes of commercial species that may be left on the cutting area according to the Minister’s directions and deadwood and rejected wood are excluded from the volume of usable ligneous matter.
Deadwood is quality M wood.
Rejected wood is a log or part of a log of a merchantable size that contains such a quantity of defects that it no longer has any value for the forest product industry, except for the development of forest biomass. Logs or parts of logs that meet the criteria provided for in Schedule 13 are deemed to have no value.
