Spring forth diversity: Specialist species contribute to the conservation value of headwater springs and streams at the landscape scale

River Research and Applications, Volume 40, Issue 5, Page 863-874, June 2024.
Abstract Headwater springs and streams often occur in relatively remote areas, reducing their exposure to human influences and thus increasing their collective capacity to support high biodiversity. Their aquatic macroinvertebrate communities can include species of conservation interest, some of which are specialists associated with groundwater inputs,
