Quebec Precarious Species Occurrence Records

Generalized occurrence data for flora and fauna in precarious situations across Quebec, published by the Quebec Natural Heritage Data Center (CDPNQ). The dataset is updated via field surveys conducted by provincial and federal governments, partners, and citizen contributions to support conservation and land-use planning.

Use Cases

• Analyze generalized occurrence territories to identify priority areas for conservation recommendations under the Act Respecting Threatened or Vulnerable Species.
• Use generalized occurrence data to assess threats and inform the preparation of recovery plans for species in precarious situations.
• Incorporate occurrence territories into environmental impact studies and ministerial authorization requests for land development projects.
• Support sustainable planning for forestry, agriculture, and municipal development by mapping territories where the CDPNQ holds species data.

Strengths

• Data is actively updated through field surveys by multiple government levels and partners.
• Includes generalized occurrences designed to protect sensitive species while indicating data presence.
• Published to improve accessibility for scientific, conservation, and land management purposes.

Limitations

• Occurrence data is generalized, hiding precise location information to protect species, limiting spatial analysis precision.
• Absence of recorded occurrences does not confirm species absence, potentially leading to false negatives in analysis.
• Specific quantitative metrics like row count, column count, and sample size are unavailable for assessing dataset scale.
