Hamster Burrow Census in Alsace for 2003 Population Status

2003 census of large hamster burrows occupied in Alsace, conducted in winter cereal and alfalfa plots. The number of burrows identified serves as an index of abundance, using a semi-exhaustive protocol validated in 2000 by the ONCFS. The dataset was last updated on the platform in March 2019.

Use Cases

• Estimate population abundance of hamsters based on the burrow count index.
• Analyze habitat preference by comparing burrow densities between winter cereal and alfalfa plots.
• Model the impact of agricultural practices on wildlife based on census data from specific plot types.
• Assess long-term population trends by comparing this 2003 index with data from other years.

Strengths

• Data collection follows a specific, validated protocol from 2000, suggesting methodological consistency.
• Covers two distinct agricultural environments (winter cereal and alfalfa) with defined sampling distances.
• Provides a temporal snapshot for a specific year (2003) in a defined region (Alsace).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2019 -03-22 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
