United Kingdom butterfly population trends for 59 species, calculated from the UK Butterfly Monitoring Scheme. Linear regression statistics (slope, standard error, P-value), trend classes, and percentage changes are provided for the full series (1976-2018), the last 20 years, and the last decade. The dataset is organized by Butterfly Conservation, the Centre for Ecology & Hydrology, the British Trust for Ornithology, and the Joint Nature Conservation Committee.
Use Cases
- Assessing long-term population decline or recovery based on linear trends over 1976-2018
- Identifying recent conservation successes or failures based on trends for the last decade
- Comparing short-term (10-year) and medium-term (20-year) trends for individual species
- Prioritizing conservation funding based on trend classes and percentage change values
Strengths
- Provides trends for 59 UK butterfly species
- Includes statistical outputs from linear regression (slope, standard error, P-value)
- Offers trend analysis across three distinct time periods: full series, last 20 years, last decade
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
