(2025). Annual abundance indices and trends for moths in Britain and Ireland from the Rothamsted Insect Survey light-trap network, 1968-2021, including country-level results for England, Scotland and Wales. NERC EDS Environmental Information Data Centre 10.5285/75161449-1382-42a4-bb91-58835740cc75 The dataset contains annual abundance indices and trends in abundance for 477 species of moths (mostly macro-moths) estimated using the data collected by Rothamsted Insect Survey (RIS) from their light-trap network between the years 1968 and 2021. The abundance indices are trends calculated using Generalized Abundance Index (GAI) models. The trends are presented as Annual Growth Rates (AGR), and the total percentage changes over the time series for each species are also provided. The indices and trends include 95% confidence limits estimated via bootstrapping. Abundance indices and trends are presented for the entire network of traps across Britain, Ireland, and the Channel Islands, as well as country level analyses for England, Scotland, and Wales.

The Rothamsted moth count data was used to produce abundance indices and associated trends using Generalised Abundance Index GAI models. The analysis results were reviewed to exclude results for species showing pronounced issues, i.e. where the indices across a significant proportion of the time series had exceptionally wide confidence intervals and or were based on very sparse data.
