This report is a summary of the results of the 'An Assessment of Best Management Practices for Water Temperature Control in the Former Morice Forest District'. The project involved water temperature monitoring at small streams within the former Morice Forest District. An assessment of the effectiveness of Best Management riparian buffer trials indicates that riparian buffers that maintain canopy densities above 70% were generally successful at minimizing stream thermal regime impacts. Sites that had demonstrated thermal regime impacts were associated with treatments that resulted in canopy densities below 70%. As well, the most significant thermal regime impacts were found at sites with strong hydro-riparian coupling of lateral wet ecosystem types. Future work in the area of variable source area analysis and riparian ecosystem classification is proposed to identify sites with similarly high levels of potential thermal regime impact. Sites with significantly modified channel morphology (ditchlines and disturbed channels) were also associated with a high degree of thermal regime impact.
