North American Beaver Occurrence Records in Russia, 1992-2018

L. А. Khlyap from the Severtsov Institute of Ecology and Evolution compiled 26 occurrence records of the invasive North American beaver (Castor canadensis) in Russia. The dataset includes 25 species-level records and one genus-level record, covering the European northwest and the Asian Far East and Kamchatka regions. Records span from 1992 to 2018 and combine visual observations from protected areas with literature sources.

Use Cases

• Mapping invasive species distribution based on described geographic coverage in European and Asian Russia.
• Studying temporal trends of species introduction based on the 1992-2018 observation period.
• Analyzing source pathways of biological invasions based on described migration from Finland and intentional introductions in the Far East.

Strengths

• Contains 26 specific occurrence records with clear species identification for 25 of them.
• Covers a 26-year temporal range from 1992 to 2018.
• Combines data from multiple sources, including field observations and published literature.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
