Country‐wide analysis of large wood as a driver of fish abundance in Swedish streams: Which species benefit and where?
Abstract Rivers are heavily affected by human impacts that threaten many fish species. Among restoration measures, the addition of large wood (LW) in streams has been shown to increase fish abundance, yet which species benefit from LW, to what extent relative to other drivers, and which factors infl...
