Quebec Precarious Plant Species Distribution Areas

6,700 occurrences for 506 plant species in precarious situations in Quebec. The dataset provides generalized geographic ranges, each with up to three zones defined by viability ratings and occurrence precision. It is produced by the Quebec Natural Heritage Data Center for conservation planning.

Use Cases

• Map 'presence', 'historical', and 'possible presence' zones for a species to guide field inventory planning.
• Analyze the spatial distribution of the 506 precarious species across ecological districts.
• Use viability ratings and occurrence precision levels to model habitat suitability for conservation projects.

Strengths

• Contains data for 506 distinct plant species in precarious situations.
• Based on a source system of over 6,700 verified species occurrences.
• Provides standardized, reproducible ranges with up to three defined geographic zones per species.

Limitations

• Ranges are generalized areas and do not model specific habitat requirements.
• The automated creation method may simplify complex natural distributions.
• Sample data and specific column definitions are unavailable for review.
