Vegetation Recovery Classification from Landsat Imagery in Alberta PBR Pilot Area

Six distinct land cover classes, including shrub land, grassland, and forest types, were classified to assess vegetation recovery from energy exploration disturbances. The Alberta Energy Regulator produced this dataset using Landsat multispectral imagery from 2008 and 2009 and derived Land Use and Land Cover data. It covers a specific pilot area for Play-Based Regulation, extending from Township 52 to 70 in Alberta.

Use Cases

• Quantify vegetation recovery rates by analyzing changes in the six land cover classes between 2008 and 2009 imagery.
• Monitor anthropogenic disturbance footprints from oil and gas infrastructure by identifying areas of vegetation loss and subsequent recovery.
• Assess the effectiveness of regional regulatory frameworks by correlating recovery class data with the spatial boundaries of the Play-Based Regulation pilot area.
• Model forest type transitions (e.g., coniferous to mixed forest) using the classified shrub land, grassland, and forest categories.

Strengths

• Derived from Landsat satellite imagery, providing standardized, wall-to-wall spatial coverage.
• Classifies vegetation into six specific, ecologically relevant categories for detailed analysis.
• Focuses on a defined regulatory pilot area spanning 18 townships, enabling targeted study.

Limitations

• Data is temporally limited to a two-year snapshot (2008-2009), preventing analysis of long-term trends.
• The classification accuracy is dependent on the source Land Use and Land Cover data, which may contain errors.
• Sample size (number of image pixels) and ground truth validation details are not provided.
