Arctic Tundra Vegetation Plots in Burned and Unburned Sites

Vegetation and environmental plot data document post-fire succession in Arctic Alaska tundra. The dataset contains complete species lists and cover abundance for plots in fire scars and adjacent unburned areas on the Seward Peninsula and Brooks Range foothills. Data was collected by ORNL_CLOUD during field surveys in late June and July of 2011 and 2012.

Use Cases

• Analyzing differences in species composition and cover abundance between burned and unburned tundra plots.
• Modeling post-fire vegetation successional trajectories using the established chronosequence of sites with varying times since fire.
• Studying baseline environmental factors, including vegetation, soils, and site descriptors, for upland tundra settings.

Strengths

• Provides a chronosequence design with sites varying in time since last fire to study succession.
• Includes complete species lists and cover abundance data for both burned and unburned areas across two study regions.
• Data collection spans two field seasons in 2011 and 2012, capturing seasonal conditions.

Limitations

• No soil samples were collected, limiting soil-specific analyses.
• Conflicting last updated dates exist between platforms (2012-07-30 and 2026-03-13).
• Specific row counts, column names, and dataset size are unknown across all sources.
