eDNA sampling reveals no negative effects of beaver recolonisation on the catchment-scale distribution of migratory fish

Key Points

• Assess the impact of beaver recolonisation on the distribution of migratory fish using eDNA sampling.
• Conducted eDNA sampling in beaver recolonised areas
• Analyzed catchment-scale distribution of migratory fish
• Utilized scripts and raw data to ensure accuracy
• No negative effects on migratory fish distribution were observed
• Beaver recolonisation did not alter the ecological balance for fish populations
