Maturity Class Code Class Definition 1 Regeneration The renewal of a forest crop by natural or artificial means. Also the new crop so obtained (5). The new crop is generally less than 1.3 m in height (1). In this context it is the new crop, not the act of renewal, that is being described. CanFI data may include volume of trees that survived disturbances such as fire or harvesting. 2 Immature In even-aged management, those trees or stands that have grown past the regeneration stage but are not yet mature. 3 Mature In even-aged management, those trees or stands that are significantly developed to be harvestable and that are at or near rotation age (includes overmature trees and stands if an overmature class has not been recognized) (1). 4 Overmature In even-aged management, those trees or stands past the mature stage (1). 5 Uneven-aged A forest, stand, or forest type in which relatively small differences exist between individual trees(1). To be classified as even-aged, the maximum difference in age permitted it is usually 10 to 20 years; if the stand will not be harvested until it is 100 to 200 years old, larger differences of up to 25 percent of the rotation age may be allowed. -8 Missing value No information available -9 Not applicable For records that are not stocked forest land Forest Type Code Class Definition 1 Softwood Stocked forest land where 76 to 100% of the canopy is coniferous 2 Mixedwood Stocked forest land where 26 to 75% of the canopy is coniferous 3 Hardwood Stocked forest land where 0 to 25% of the canopy is coniferous -8 Missing value No information available -9 Not applicable For records that are not stocked forest land Predominant Genus Code Class Definition 1 Spruce Most abundant tree genus is Picea 2 Pine Most abundant tree genus is Pinus 3 Fir Most abundant tree genus is Abies 4 Hemlock Most abundant tree genus is Tsuga 5 Douglas-fir Most abundant tree genus is Pseudotsuga 6 Larch Most abundant genus is Larix 7 Cedar and other conifers Most abundant genus is one of Thuja, Juniperus, Taxus, or Chamaecyparis 8 Unspecified conifers Most abundant genus identified as conifer only 9 Poplar Most abundant tree genus is Populus 10 Birch Most abundant tree genus is Betula 11 Maple Most abundant tree genus is Acer 12 Other broadleaved species Most abundant genus is one of Carya, Juglans, Alnus, Ostrya, Carpinus, Fagus, Quercus, Ulmus, Morus, Liriodendron, Magnolia, Sassafras, Platanus, Prunus, Gleditsia, Robinia, Tilia, Nyssa, Cornus, Arbutus, Fraxinus, Salix, Gymnocladus, Celtis, Amelanchier, Corylus, Crataegus, Ilex, Malus, Nemopanthus, Rhus, or Sorbus 13 Unspecified broadleaved species Most abundant genus identified as broadleaved only -8 Missing value No information available -9 Not applicable For records that are not stocked forest land 118
