Feral Goats (Capra hircus)

Not Wanted!Status: Goats are considered to be domestic stock in Tasmania and ownership needs to be determined before any action is taken to destroy animals. Unauthorised shooting of goats could result in legal action and has potential to undermine eradication efforts.

Male goats (billy goats) are generally larger than females (nanny goats), with both being 1-1.5 metres in length. The coat can be shaggy or short; and varies in colour from white, brown or black or a combination. Both sexes have permanent horns.


History

Goats first arrived in the Australian landscape with the first fleet in 1788. They were small and easy to transport, hardy and ate a range of plants - as well as providing milk and meat for the early years of a growing colony.

During the 19th century sailors released goats onto islands to provide for emergency food supplies. More recently, goats have been used to keep plantation forests and inland pastoral land free of weeds. Feral herds developed as these domestic goats escaped, were abandoned or were deliberately released. There are now estimated to be at least 2.6 million feral goats across the Australia.

In Tasmania, many feral goat populations probably built up in the 1980s from the offspring of haphazard escapes and releases: crossbred varieties are common.


 

Distribution

In Tasmania, more than 160 herds of feral goats have been identified by DPIPWE since 1991. Feral goats have been recorded in various habitats, including rainforest and within the boundaries of the Tasmanian Wilderness World Heritage Area (TWWHA).

Environmental Impacts

Feral goats invade bush and browse a wide variety of native plants including blackwood, drooping she-oak, native cherry, coffee berry, round-leaf riceflower, rough dogwood and forest germander. No plant species are immune from goat damage. Goats can climb trees and break off limbs up to 3m off the ground! Locally, trampling by goats may lead to soil erosion. In areas where there is useful stock feed or plantation, browsing by feral goats may be economically significant. Feral goat herds also act as reservoirs for sheep parasites and diseases.

 

Reproduction

Feral goats can breed twice a year, with twins and triplets being common.

 

Control Measures

Domestic goat keeping is the source of new feral populations in Tasmania, and there is always the risk of reinfestation by feral goats through escapes from domestic herds. Overcoming the problem of feral goats in Tasmania depends on owners of domestic goats keeping their stock inside fences, and disposing of unwanted animals responsibly. Keep them inside the fence and stop the spread! In Tasmania's rugged terrain, shooting by trained professionals is the best option for humanely eradicating feral goat populations.

Did you know?

Goats are sociable animals and 'Judas goats' (goats with radio-collars attached) can be used to locate hard to find goat herds.
