Forest Reproductive Material Sites in Great Britain with National Register Attributes

The dataset contains polygons representing approved basic material sites for forest reproduction in Great Britain, regulated under the Forest Reproductive Material (Great Britain) Regulations 2002. Each entry includes a National Register Identification Number, grid reference, material category, and land area. The Forestry Commission maintains the register as the Official Body for England, Scotland, and Wales.

Use Cases

• Mapping the distribution of approved seed stands and orchards based on the geospatial polygon data.
• Analyzing the composition of basic material categories (e.g., seed sources, clones) for forest management planning.
• Verifying regulatory compliance for marketed forest reproductive material based on register reference linkages.
• Studying the provenance and genetic origin of planting stock using the region and seed zone attributes referenced in the National Register.

Strengths

• Data is linked to a formal National Register with unique identifiers for traceability.
• Covers 46 controlled tree species and the genus Populus as defined by regulation.
• Attributes include a national grid reference and land area in hectares for spatial analysis.
• Distinguishes six types of basic material, including seed stands, orchards, and clones.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
