In 1997, many very young Senna seedlings were noticed in the Cassia corner and outside the northern boundary fence. To study the effects of grazing on these seedlings outside the reserve, three populations were identified and measured to the north of the fence, and a fourth population just south of the fence in the Reserve, not otherwise enclosed.

Two of the outside populations were enclosed in triangular fences, one with sheep netting to protect from grazing by sheep, the other with both sheep and rabbit netting to protect against both sheep and rabbits. A third population was left unprotected. The population inside the Reserve was assumed to be protected from all grazing by the Reserve fence. The aim was to follow the fates of the original cohort.

This is version 2.1 of the Koonamore Senna Population data release.

Change log for the Senna seedling observations

  • V2.1, 2026-02-16; Specht, Miranda Fittock and Arun Singh Ramesh; Ensured dates recorded were in ISO format YYYY-MM-DD. The dataset was edited for accuracy, additions made to data set to comply with TERN standards.
  • V2, 2025-04-29; Alison Specht; Digitised and organised data files to comply with FAIR standards, aligning vocabularies with the TERN vocabularies and created comprehensive metadata.
  • V1, 2008-2014; Russell Sinclair; digitised field data sheets to be delivered to the AEKOS TERN portal. added required V1 metadata in the AEKOS portal
