Koonamore Cassia Corner: Plant Abundance and Life Stage Data, 1940-2014

26 survey instances from 1940 to 2014 track the abundance of Cassia (Senna artemesioides) in a 7150 m2 area of the TGB Osborn Vegetation Reserve. The dataset includes counts of individuals and their life stage (adult or juvenile). This version 2.1 release is managed by the Terrestrial Ecosystem Research Network, with data originally digitized from field sheets.

Use Cases

• Modeling long-term population trends of Cassia based on 74 years of intermittent survey data.
• Analyzing the ratio of adult to juvenile plants over time to infer recruitment success.
• Studying vegetation reserve management outcomes based on species abundance records.

Strengths

• Covers a long temporal span of 74 years (1940-2014).
• Includes life stage classification (adult/juvenile) for each recorded individual.
• Data is standardized to FAIR and TERN vocabulary standards as of the 2026 version.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data collection is intermittent across 26 instances over 74 years, not continuous.
