Ragwort blooms spectacularly in Bridport this summer
- Ragwort has bloomed spectacularly this summer, with its bright yellow flowers appearing in various locations.
- The plant is toxic to livestock, causing liver damage if ingested, and poses a greater risk when dried in hay.
- This year's unusual weather has led to a significant decline in insect populations that typically rely on ragwort for food.
This summer has seen an impressive bloom of ragwort, characterized by its tall, flat-topped clusters of bright yellow flowers. However, this plant is controversial due to its toxicity, particularly to livestock such as horses and cattle, where ingestion can lead to severe liver damage. The plant's strong odor serves as a deterrent to herbivores, but it poses a greater risk when dried and included in hay, as its scent diminishes, making it less detectable to animals. Despite its dangers, ragwort is crucial for biodiversity, providing food for over 80 invertebrate species, including the cinnabar moth and red soldier beetles. The moth's larvae feed voraciously on the plant, while the beetles are often seen in pairs during warm weather. However, this year has been notably different, with a significant decline in insect populations observed in areas where ragwort typically flourishes. The unusual weather patterns this year, including the wettest spring since 1986 followed by a cool summer, have contributed to the stress on insect populations already affected by habitat loss. Observations indicate that many areas that would normally be bustling with insect life have been eerily quiet, with few sightings of the expected species. As autumn approaches, ragwort is beginning to shed its seeds, which can remain dormant for years yet still be viable. This cycle of growth and decline highlights the complex relationship between this plant, its ecosystem, and the ongoing challenges faced by insect populations in changing environmental conditions.
