Lichen Ammonia Avoidance Data with Acidofile Indication Values, 1991-1998

Acidofile Indication Values (AIW) for ammonia-avoiding lichens, measuring environmental change per hour loft. A decrease in the AIW indicates environmental deterioration. The dataset was published by the Dutch Ministry of the Interior and Kingdom Relations under a CC-PDM-1.0 license.

Use Cases

• Tracking environmental deterioration over time based on the Acidofile Indication Value (AIW) metric.
• Analyzing trends in ammonia pollution using lichen as a bioindicator.
• Correlating changes in lichen communities with atmospheric conditions per hour loft.

Strengths

• Focuses on a specific, measurable bioindicator (Acidofile Indication Value) for environmental assessment.
• Covers a defined multi-year period (1991-1998) for trend analysis.

Limitations

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