CONSERVATION

Conservation
Tasmania Zoo acts as home to a number of threatened, endangered and critically endangered species, recognised on both an international and national level. The International Union for the Conservation of Nature and Natural Resources (IUCN) Red List provides a comprehensive, objective global approach for evaluating the conservation status of plant and animal species, whilst the Environment Protection and Biodiversity Conservation Act 1999 (the EPBC Act) provides the Federal framework to protect and manage Australia’s flora, fauna and ecological communities.

Tasmania Zoo is dedicated to continuous contribution to wildlife conservation and to the education of the community at large. As a member of the Zoo and Aquarium Association, we work closely with all Australasian zoos, and are involved in various species management programs.


DEVIL’S HEAVEN

Devil’s Heaven is a dedicated conservation breeding program, situated within Tasmania Zoo’s precinct. Featuring advanced bio-secure breeding pens, Devil’s Heaven has been home to a successful breeding population of Eastern Province Devils for over 10 years.

Devil’s Heaven has received much support from local organisations wanting to do their part to save this iconic species. In return, Devil’s Heaven supplies healthy, disease-free devils for display within Tasmania Zoo. Feeding and interpretation is conducted daily for tourists, locals and school groups to assist with the conservation of the species.

DEVIL FACIAL TUMOUR DISEASE (DFTD)

The Tasmanian devil has suffered a dramatic population decline in recent years due to devil facial tumour disease (DFTD), an infectious cancer transmitted through biting. The low genetic diversity in Tasmanian devils has compounded the problem, and the recent discovery that the tumour itself is rapidly evolving has amplified concerns for the medium-term survival of this unique and iconic Australian species.

DFTD is one of the only cancers known to spread as a contagious disease. The cancer is spread from devil to devil primarily through biting. Transmitted tumour cells are not rejected by the recipient animal’s immune system. Due to the extremely close genetic kinship within the entire population, infected devils are veritable ‘universal organ donors’ to one another, passing on tumour cells during fights associated with feeding, territoriality and mating, which are then able to establish themselves in the opponent.

Once a devil is infected, signs of the disease appear in the mouth within a few short months, usually in the form of small lesions or pimple-like lumps. These small blemishes quickly develop into large tumours that grossly distort the face and neck (and sometimes other parts of the body). The devils soon find it difficult to eat and drink, leading to death from starvation, dehydration and the breakdown of body functions, usually within three months of the initial appearance of tumours. In the later stages of the illness, the cancer typically metastasizes to vital organs, including the lungs and brain.

Infectious DFTD cells first derived from the body cells of a healthy Tasmanian devil in 1996 or perhaps a year or two earlier. As such, the tumour cells can only survive within Tasmanian devils. No other species, not even the devil’s closest kin – the quolls and other Dasyuridae species (marsupial predators) are capable of ‘hosting’ Tasmanian devil cells of any type, because their own immune system would immediately recognise the tumour cells as ‘non-self’ and destroy them.
Proyecto Tití is a multi-disciplinary on-site conservation program that combines field research, education initiatives and community programs to make the conservation of natural resources economically feasible for local communities in Colombia. The program is designed to provide useful information to assist in the long-term preservation of the cotton-top tamarin and to develop local community advocates to promote conservation efforts in Colombia.

Rainforest Rescue has initiated the Save the Cassowary campaign in collaboration with Australian partner zoos, government departments, local councils, Aboriginal Corporations and business partners to urgently highlight the future of the endangered ‘Rainforest Gardener’, the Southern Cassowary. Rapid development has eliminated 85% of its habitat and current estimates fear fewer than 1,000 birds are left in the wild.
