Experimental Vegetation Plots on Three Yukon Mine Tailings Sites

Revegetation experiments were established on three abandoned toxic mine tailings sites in Yukon between 2003 and 2006, with a follow-up assessment in 2009. The study tested treatments including seeding of tufted hair grass and soapberry, transplants, and soil amendments like compost, fertilizer, and lime. Performance, flowering success, and chemical analytical data are presented.

Use Cases

• Compare revegetation performance and flowering success data across the Mount Skukum, United Keno, and Wellgreen sites.
• Analyze the impact of soil amendment treatments, such as compost, fertilizer, manure, peat, and lime addition, on plant survival.
• Assess chemical analytical data from the tailings sites to understand soil conditions affecting revegetation success.
• Evaluate the long-term survival of plots established in 2003, which persisted for six years, as a nucleus for effective revegetation.

Strengths

• Data covers three distinct experimental sites (Mount Skukum, United Keno, Wellgreen) for comparative analysis.
• Includes results from experiments spanning a 6-year period from initial setup (2003-2006) to reassessment (2009).
• Documents multiple treatment variables including seeding, transplanting, and several soil amendment types.

Limitations

• Data is presented in HTML format with figures and tables, not in a structured, machine-readable tabular format.
• Sample size is limited to three specific mine sites, limiting generalizability to other environments.
• The 2009 reassessment represents a single snapshot; no continuous time-series data is provided.
