Insect Conservation and Diversity, Volume 17, Issue 5, Page 758-787, September 2024.Monitoring invertebrates in cereal fields in southern England over 50 years (1970–2019) showed an overall decline in abundance. For taxa at the order/family level, 47% declined in abundance, 16% increased and 37% showed no change. Most functional groups declined, expect for pollinators—whose abundance did not change overall.
