Arctic Vegetation Plot Data from Umiat, Alaska, 1951

Vegetation cover and environmental plot data were collected from 51 homogeneous stands in the Umiat region of Alaska during July and August 1951. The dataset includes species composition, percent cover classes, soil moisture, and topographic features like slope and aspect. It is provided by the National Aeronautics and Space Administration.

Use Cases

• Analyzing historical plant species composition and percent cover across 51 stands.
• Investigating correlations between soil moisture levels and vegetation types.
• Studying the influence of topographic position, slope, and aspect on Arctic plant communities.
• Establishing a 1951 baseline for vegetation change studies in the Alaskan Arctic foothills.

Strengths

• Data is spatially explicit, covering 51 distinct vegetation stands in a defined Arctic region.
• Includes multiple measured environmental variables: species cover, soil moisture, and topography.
• Provides a focused temporal snapshot from a specific growing season (July-August 1951).

Limitations

• Key facts like row count, file size, and specific column names are unavailable from all sources.
• There is a conflict on the 'last updated' date: one source states 2026-03 13, while another states 1951-08-31.
• The license is vaguely specified as 'other-license-specified', requiring further investigation.
