Senna Seedling Survival Under Grazing Pressure in Koonamore Reserve

Three fenced populations and one control group of Senna seedlings were monitored to study the effects of sheep and rabbit grazing outside a South Australian vegetation reserve. The dataset was digitized and maintained by researchers including Russell Sinclair, Alison Specht, and Miranda Fittock, with updates spanning from 2008 to 2026. It tracks the original cohort's fate, with version 2.1 released in February 2026.

Use Cases

• Analyze seedling survival rates by comparing fenced (sheep-net, rabbit-net) and unfenced population groups.
• Model the impact of grazing pressure using treatment variables like fence type and location (inside/outside reserve).
• Track cohort fate over time using longitudinal observation dates recorded in ISO format (YYYY-MM-DD).
• Assess the effectiveness of reserve boundaries by comparing the protected internal population to external control groups.

Strengths

• Data spans nearly two decades of monitoring, with records from 2008 through 2026.
• Structured according to FAIR principles and aligned with TERN vocabulary standards.
• Includes multiple treatment groups (sheep netting, rabbit netting, unprotected, reserve-protected) for controlled comparison.

Limitations

• Unknown sample size (row count) for statistical power assessment.
• Geographic scope is limited to a single reserve site (Koonamore) in Australia.
• Initial data collection methods prior to 2008 digitization are not detailed.
