Hamster Burrow Census in Alsace for 2004 Population Status

2004 census of large hamster burrows occupied in Alsace, conducted in winter cereal and alfalfa plots. The number of burrows identified via a semi-exhaustive protocol validated in 2000 by the ONCFS serves as an index of abundance. The dataset was last updated on the platform in March 2019.

Use Cases

• Modeling population abundance indices based on burrow counts.
• Analyzing habitat preference by comparing burrow density between winter cereal and alfalfa plots.
• Assessing the impact of agricultural practices on hamster populations based on census data.
• Creating geospatial distribution maps of hamster burrows for conservation planning.

Strengths

• Census data is from a specific year (2004), providing a temporal snapshot.
• The survey protocol (semi-exhaustive, validated in 2000) is explicitly mentioned.
• Spatial coverage is clearly defined as the Alsace region.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2019-03-22 00:00:00; freshness should be verified.
• Row count and file format are unknown, which may limit suitability assessment.
