Scotch Broom Distribution in Garry Oak Ecosystems from Sentinel-2 Imagery

Spatial predictors and model outputs for investigating the distribution of Scotch broom (Cytisus scoparius) within Garry Oak ecosystems in British Columbia, Canada. The dataset was derived from Sentinel-2 multispectral imagery and includes raw spectral bands, derived vegetation indices, and Random Forest classification outputs. It was authored by Willa Pepin and last updated on May 2, 2026.

Use Cases

• Mapping invasive species presence and absence based on Random Forest classification outputs.
• Analyzing seasonal vegetation changes based on temporal metrics for NDVI, ciRED, and TREI indices.
• Conducting accuracy assessments for land cover classification using provided confusion matrices and accuracy metrics.
• Studying spectral signatures of specific plant communities using surface reflectance bands B01–B12 and Tasseled Cap Transformations.

Strengths

• Includes multiple predictor types: 12 surface reflectance bands, Tasseled Cap Transformations, and temporal change metrics for three vegetation indices.
• Model outputs are provided as both continuous probability surfaces and binary classification maps generated via thresholding approaches.
• Accuracy assessment was conducted using validation data, with performance evaluated through confusion matrices and class-specific accuracies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific study region in British Columbia.
