TGB Osborn (Koonamore) Vegetation Reserve, Senna Population Data
<p>In 1997, many very young <em>Senna</em> 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. </p>
<p>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. </p>
<p>This is version 2.0 of the Koonamore Senna Population data release.</p>

- Purpose
- In the mid-1920's Professor Theodore George Bentley Osborn, Professor of Botany in the University of Adelaide, put forward strong scientific arguments concerning the lack of knowledge of the ecology of arid zone vegetation, and the effect of grazing on it. In 1925, a parcel of land of around 390 ha was identified in Koonamore Station in South Australia and fenced to exclude rabbits and other stock, and Mr Wilcox, one of the directors, had a three-roomed house erected to serve as a field laboratory. The area was originally referred to as the Arid Region Flora Reserve but later was named the TGB Osborn Vegetation Reserve after its founder. For simplicity it is commonly referred to as the Koonamore Vegetation Reserve. There have been some unwanted animal incursions over the years, but these have been rare. In 1931, for example, rabbits were able to enter due to fence damage. Kangaroos and emus are not fully excluded. As is clear from the objectives stated by TGB Osborn, the reserve was to provide the basis for systematic measurements of the now-protected vegetation. Osborn and his team (including Prof. J.G. Wood and Mr Terry Paltridge) set up a series of quadrats (square plots) and photopoints within the reserve. A series of transects was later added. All of the foregoing were permanently marked, and observations on species occurrence (presence and abundance) and physical measurements of the plants were made repeatedly, but at varying intervals. <br></br>
