Titre : 90 years of monitoring change in arid zone

A 400 hectare piece of land in South Australia’s outback, 400 kilometres north-east of Adelaide, is providing important data to help researchers and land and environmental managers understand arid zone ecology and the impacts of grazing by sheep and pests.

Présentation
The Koonamore Vegetation Reserve, located in the centre of Koonamore Station, is one of the world’s oldest continuously monitored scientific sites.

Since it was established by Professor TGB Osborn in 1926, the Koonamore Vegetation Reserve has provided generations of scientists, students and volunteers the opportunity to help preserve and study the unique ecology.

Fencing the reserve has meant records contain a long history of vegetation without grazing over many years. Change over time is monitored by recording vegetation changes (species, canopy size and density) within permanent quadrats and with photos taken at 68 photopoints, usually every year.
