Status summary

The WBS trend shows that Dipper populations have fluctuated over the last thirty years, but shown little overall trend. The species is a good indicator of acidity and other water pollution (Ormerod & Tyler 1989, 1990), so warrants careful monitoring. Breeding performance has improved strongly over time, and laying dates have become earlier, perhaps because of climate change (Crick & Sparks 1999). Broods now average larger, and there has been substantial reduction in failure rates of nests at the egg stage.
