UK Moth Population Trends from National Light-Trap Network (1968-2016)

432 species of moths, mostly macro-moths, have their national population trends modeled from 1968 to 2016. Trends are calculated using a Generalised Abundance Index (GAI) model and presented as year coefficients, Annual Growth Rates (AGR), and total percentage changes with confidence intervals. A related subset of trends was produced specifically for the Atlas of Britain & Ireland’s Larger Moths, using data from Great Britain between 1970 and 2016.

Use Cases

• Assessing long-term population changes for specific moth species based on Annual Growth Rates (AGR) and total percentage change metrics.
• Analyzing year-to-year population fluctuations using the statistical model's year coefficients.
• Evaluating the statistical certainty of trend estimates for conservation prioritization using the provided 95% and 90% confidence intervals.
• Comparing national UK trends with trends specific to Great Britain as presented in the Atlas subset.

Strengths

• Covers a large taxonomic scope with trends for 432 moth species.
• Provides multiple statistical metrics (year coefficients, AGR, percentage change) with confidence intervals for each trend.
• Based on long-term, standardized monitoring data collected over a 48-year period (1968-2016).

Limitations

• Dataset is marked as withdrawn on all listed platforms, indicating it may no longer be available for download or use.
• Column names and detailed structure are unknown, limiting understanding of the data's precise organization.
• Critical metadata such as license, author, and exact row count is missing from all sources.
