The Red Fox (Vulpes vulpes) is a medium-sized carnivore native to North America, most of Asia, and parts of North Africa. It is the largest of the true fox species and has the widest natural range of any terrestrial carnivore. It was deliberately introduced in Victoria to provide sport for hunters in the 1860s, and spread rapidly, reaching Southwest Western Australia by 1917.
The greater Adelaide area was inhabited by nine species of bats before European settlement, and all nine still exist today, albeit in smaller numbers. Bats are still considered common in South Australia but because they are active at night and make sounds beyond the range of human hearing, we sometimes overlook them.
Butterflies of South Australia
South Australia is home to a unique array of butterflies.
The insect order Lepidoptera refers to butterflies and
moths. It is believed that prior to European settlement
54 permanent species inhabited South Australia.

A striking, colourful bird, the Rainbow Bee-eater is medium sized, with a long slim curved bill and a long tail with distinctive tail-streamers. It has a golden crown and a red eye set in a wide black stripe from the base of the bill to the ears, which is edged with a thin blue line. The throat is orange-yellow, with a broad black band separating it from a green breast. The upperparts are green, with the flight feathers coppery and black tipped. The underwings are bright orange, with a black edge. The lower abdomen is blue. The tail is black, including the long tail streamers, with a blue tinge. Females have shorter, thicker tail streamers than males, but are otherwise similar. Young birds are duller and greener, lacking the black band on the chest and the long tail streamers.

Landcare is an international movement of citizens, landowners, and professional land managers, including conservation biologists, who are working together to take care of the land in a way that produces a broad range of improved economic, social, and environmental conditions (the triple bottom line). As such, landcare contributes to the science and practice of conservation biology and links biodiversity goals to positive economic and community development objectives.
The “landcare” movement began in 1986 in Australia where there are now approximately 5000 community landcare groups. Forty percent of farmers and land managers across Australia are members of these landcare groups.
Riparian lands and their vegetation provide important habitat for land-based plants and animals. Riparian land often contains a high diversity of living organisms, and plays a crucial role as a corridor for the movement of plants and animals. Even though riparian lands may occupy only a small percentage of the catchment landscape, they are vital to its long-term health and sustainable land management.
