“…In addition, the scale of a particular change relative to a particular catchment or river basin will strongly influence the likely impact; the cumulative effects of multiple interventions are also difficult to assess (e.g., Golden & Hoghooghi, 2018). When ecohydrological impacts are a primary component of a restoration scheme, a range of research tools is available allowing interdisciplinary teams of specialists to make qualitative and quantitative assessments with appropriate consideration of uncertainty and risk (e.g., Wohl et al, 2015Wohl et al, , 2023Smith et al, 2021;Luo et al, 2024). Surprisingly, when the focus of restoration is more ecological or species-focused, and carried out by land-or rivermanagement agencies lacking appropriate specialist expertise, ecohydrological assessment may be only cursory and expert evaluation is often lacking.…”
