TGB Osborn Senna Populations: Grazing Impact Study in Koonamore Reserve

A long-term study initiated in 1997 tracks the fate of Senna plant seedlings under different grazing protections near the TGB Osborn Vegetation Reserve in Koonamore. The dataset, maintained by the Terrestrial Ecosystem Research Network (TERN), includes observations from four populations, with three subjected to controlled grazing treatments. This is version 2.1, last updated in 2026, and supersedes previous releases.

Use Cases

• Modeling seedling survival rates based on grazing protection treatments described in the study.
• Analyzing long-term population trends for Senna plants based on the cohort tracking mentioned.
• Comparing plant growth and mortality inside a protected reserve versus outside grazing zones.

Strengths

• Data is explicitly versioned and maintained, with a change log showing updates to version 2.1 in 2026.
• The study design is clearly described, involving four distinct populations with controlled grazing treatments.
• Data has been curated to comply with FAIR and TERN ecosystem standards as noted in the version log.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The exact temporal coverage beyond the 1997 start date is not specified in the provided metadata.
• Row count and dataset scale are unknown, which may limit suitability assessment.
