Forest Basal Area Estimates for Canada's Forested Ecosystems, 1985–2011

Natural Resources Canada provides a 30-meter resolution geospatial dataset of forest basal area across Canada's forested ecosystems. The data, covering approximately 650 million hectares, was generated for the period 1985–2011 by combining lidar plot data with Landsat pixel composites using a nearest neighbour imputation approach. This product is part of the National Terrestrial Ecosystem Monitoring System and is intended for strategic-level forest monitoring.

Use Cases

• Modeling forest biomass and carbon stocks based on the derived basal area metric.
• Analyzing long-term trends in forest structure across Canada based on the 1985–2011 time series.
• Calibrating or validating other remote sensing products using the peer-reviewed, lidar-informed methodology.
• Strategic-level forest monitoring and reporting as indicated by the dataset's intended purpose.

Strengths

• Covers approximately 650 million hectares of Canada's forested ecosystems.
• Based on peer-reviewed science and a documented methodology combining lidar and Landsat data.
• Provides a consistent 30-meter spatial resolution for analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is not intended for operational-level forest management, limiting its use for fine-scale planning.
• Row count is unknown, which may limit suitability assessment.
