Canadian primary forest dataset is a satellite-based forest age map for
2019 across Canada's forested ecozones at a 30-m spatial resolution.
Remotely-sensed data from Landsat (disturbances, surface
reflectance composites, forest structure) and MODIS (Gross Primary
Production) are utilized to determine age.
Forest age can be determined where disturbance can be identified directly
(disturbance approach) or inferred using spectral information (recovery
approach) or using inverted allometric equations to model age where there
is no evidence of disturbance (allometric approach). The disturbance
approach is based upon satellite data and mapped changes and is the most
accurate. The recovery approach also relies upon satellite data plus logic
regarding forest succession, with an accuracy that is greater than pure
modeling.
Given the lack of widespread recent disturbance over Canada's forests, the
allometric approach is required over the greatest area (86.6%). Using
information regarding realized heights and growth and yield modeling, ages
are estimated where none are otherwise possible. Trees of all ages are
mapped, with trees >150 years old combined in an "old tree" category.
