Pre- and Post-Wildfire Soil Metrics from Oregon's South Fork McKenzie River

Soil data from the South Fork McKenzie River in Oregon, USA quantifies the impact of the 2020 Holiday Farm wildfire. Measurements include sample depth, moisture content, texture percentages, and nitrate/nitrite/carbon metrics, collected in July 2020, February 2021, and June 2021. The study by the University of Nottingham and US Forest Service partners compares soil response in restored versus unrestored river reaches.

Use Cases

• Analyze changes in moisture content and nitrate levels across three sampling dates to assess post-wildfire soil recovery.
• Compare sand/silt/clay percentages and texture classifications between restored and unrestored river reaches.
• Model carbon metric variations using sample depth and collection timing as predictors of wildfire impact.

Strengths

• Data captures a specific wildfire event with samples collected at three distinct time points: July 2020, February 2021, and June 2021.
• Includes multiple soil property measurements such as texture percentages and nutrient metrics for comparative analysis.
• Designed to quantify differences between restored and unrestored environmental conditions following a disturbance.

Limitations

• Sample size and spatial extent are limited to one river system, reducing generalizability.
• Temporal coverage is limited to three sampling campaigns over approximately one year.
• Lack of column-level metadata and sample data hinders immediate assessment of data structure and completeness.
