Eremophila alternifolia browsed by rabbits

A young 45-cm high narrow-leaved fuschia-bush (Eremophila alternifolia) in the Vulkathunha-Gammon Ranges National Park, South Australia, showing the distinctive diagonal chisel-like cuts made by rabbits. Rabbits have eaten all the accessible young leafy shoots, leaving only two shoots in well-protected recesses of the plant and a few mature leaves. This particular specimen is heavily browsed […]

Feral Goat habitat, South Australia

This series of images shows typical feral goat habitat in South Australia: 1. Feral goat habitat on Arkaroola in the North Flinders Ranges, South Australia. With limited road access, goat control is very difficult in terrain like this. Most control is by shooting from helicopters or by hunters on foot. 2&3. Inaccessible feral goat habitat, […]

Feral goats herding

Image shows mustering 1600 feral goats in the North Flinders Ranges, South Australia. Photo taken 1979 by R. Henzell. The goats were forced out of rugged, inaccessible terrain with a light aircraft, and then transferred to a ground crew in more open terrain. The photo was taken after the transfer. The ground crew, on motorbikes […]

Bounceback – Flinders Ranges

Bounceback is a major ecological restoration program operating in the semi-arid Flinders and Olary bioregion of South Australia with the following broad aims: * Link efforts to conserve and enhance biodiversity across the region * Restore the natural ecological processes across the region, with particular focus on core areas of the Flinders Ranges National Park […]

Impact of rabbit haemorrhagic disease on introduced predators in the Flinders Ranges, South Australia

The impact of rabbit haemorrhagic disease (RHD) on the population dynamics and diet of foxes and feral cats was studied in the Flinders Ranges, South Australia. Populations of both foxes and cats decreased substantially some 6–10 months after the advent of RHD, when rabbit numbers were reduced by 85%. The diet of foxes changed as […]

The effect of rabbit control and RHD on vegetation condition and grazing patterns of other herbivores in the semi-arid pastoral zone.

An experiment was begun during 1992 in the central Flinders Ranges to determine how the specific nature of rabbit grazing affected vegetation communities, what compensatory grazing occurred by sheep and kangaroos when rabbits were removed and whether pasture condition could improve without any additional controls on total grazing pressure. In late 1995, RHD reduced rabbit […]

Rabbits, goats and the growth and regeneration of arid zone perennial vegetation.

Compared with short-lived plants, trees and shrubs contribute disproportionately to landscape and ecosystem stability in the arid zone because of their perennial nature and drought resistance. The introduction of exotic herbivores however, has led to the suppression of the regeneration of many trees and shrubs, threatening their long term survival. The herbivores responsible for this […]
