Alder Shrub Cover and Soil Properties in Alaska, 2019

ABoVE: Alder Shrub Cover and Soil Properties, Alaska, 2019, V2 holds field measurements of vegetative cover and soil characteristics from sites along the James W. Dalton Highway in interior Alaska. The data were collected by the National Aeronautics and Space Administration during August 2018 and 2019. It includes vegetation cover percentages, alder biomass and age structure, soil metrics like carbon content, and NDVI trends from 2000 to 2020.

Use Cases

• Modeling alder biomass expansion based on field-measured allometric relationships.
• Analyzing correlations between shrub cover and soil properties like carbon and nitrogen content.
• Studying long-term vegetation trends using the provided NDVI data from 2000-2020.
• Mapping tundra ecosystem changes along a specific transect in interior Alaska.

Strengths

• Includes multi-year field data from 2018 and 2019, providing temporal context.
• Combines detailed vegetation metrics (percent cover, biomass, age structure) with soil laboratory analysis.
• Integrates field observations with a 20-year satellite-derived NDVI trend (2000-2020).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Spatial coverage is limited to transects along a single highway in interior Alaska.
