Koonamore Myoporum Assessment: Individual Tree Growth Over Decades

TGB Osborn (Koonamore) Vegetation Reserve hosts a long-term monitoring dataset tracking individual Myoporum plants from 1955. Measurements include species ID, height, crown diameters, basal circumference, health comments, and geolocation for each tagged plant, with records primarily spanning 1975 to 2011. The dataset has been cleaned and standardized to FAIR principles by the Terrestrial Ecosystem Research Network (TERN), with version 2.1 released in February 2026.

Use Cases

• Analyzing individual tree growth rates over time based on repeated height and circumference measurements.
• Studying crown development and canopy architecture using recorded N-S and E-W diameter data.
• Assessing plant health and mortality trends from the comments on tree health field.
• Modeling population dynamics and spatial distribution using unique plant IDs and geolocation data.

Strengths

• Provides a long-term time series with a maximum of 21 measurements per plant over a 36-year period (1975–2011).
• Data is individually tracked with metal tags and unique IDs, enabling longitudinal analysis at the organism level.
• Dataset has been cleaned and standardized to comply with FAIR and TERN vocabulary standards, as per the version 2.1 change log.

Limitations

• Key metadata such as exact row count, column names, file size, license, and author are not provided in the available sources.
• The primary temporal coverage ends in 2011, with no indication of more recent measurements.
• Conflicting 'last updated' dates (2026-04-17 and 2026-04-07) across platform entries create uncertainty about the most current version.
