100 years ago the most degraded part of a pastoral property near Yunta (SA) was fenced off to study the recovery of vegetation once stock had been removed. The idea of fencing out stock and monitoring ecological change was a science innovation of the time.
Recovery of many species was slow until a vigilant campaign eradicated rabbits about 50 years ago which, coupled with good seasons, enabled a rapid regeneration of previously rare plants.
The centenary is being celebrated on Oct 11-12 at Yunta and Koonamore. See here for more information on the event.
