Australia's Endangered Keystone Species by michelle https://padlet.com/mgralike/vjbc6tr7rw4m We need to care! en-us 2017-01-30 00:13:32 UTC 2025-09-24 04:01:53 UTC hello@padlet.com Tasmanian Devil https://padlet.com/mgralike/vjbc6tr7rw4m/wish/150129731 - Suffers from devil facial tumour disease
-The species survives in the wild only on the Apple Isle
- Tasmanian Devils have lost over 60% on their population since the mid 1990's.
-The 1944 estimate said there was nearly 150,000 healthy animals, now only 20,000-50,000
- Devil Facial Tumour Disease can spread through simple altercations such as a bite or a scratch also genetic make up. Being hit by cars and killed by people for being a pest also contributes to the decline in their population. 
- Vaccine studies are now being implemented to help prevent the decline in the species numbers.

Threats: clearing of Mt Gardener threatens the availability of food
-foxes and feral cats hunt the potoroo

Their consumption helps to maintain balance in their respective ecosystems. 

However, they are threatened by feral cats and bushfires

Its distribution has declined dramatically, especially in the more arid parts of its range, with populations declining rapidly after the arrival of the cane toad.
Quolls become sexually mature at one year of age. During the mating season (around June to August), males expend considerable energy fighting other males, and do not survive to breed a second year

Threats: agricultural expansion that creates distance between colonies]]> 2017-01-30 00:20:41 UTC https://padlet.com/mgralike/vjbc6tr7rw4m/wish/150129750 Great White Shark https://padlet.com/mgralike/vjbc6tr7rw4m/wish/150129792 -predatory marine animal ranging from 1.5-3m in size.
-largest specimen have been known to grow up to 6m
- eats seals and sea lions.
- currently protected under the state legislation
- frequently caught in nets and fishing lines.
- population during 1950s was 10 000 and average number of sharks caught in nets decreased 70

Was legally hunted for its leather in the 19th century which severely reduced the sharks concentration]]> 2017-01-30 00:21:37 UTC https://padlet.com/mgralike/vjbc6tr7rw4m/wish/150129801 Red-tailed black cockatoo https://padlet.com/mgralike/vjbc6tr7rw4m/wish/150129803 Importance:  They are pollinators 

Other Information:  Found screeching around the South Australian and Victorian skies is yet another endangered Australian bird. Population estimates are vague, but have been in decline since 1989 when it has been suggested there were 500-1000 adults.

Threats: Because of encroaching desert boundaries they have become isolated. Pressured further by expanding agriculture, their food sources and nesting areas are being cleared, leaving these birds without nutrition or the opportunity for repro
duction.

- They were hunted until the 1920's and their population never recovered.
Food
- They feed on small marine animals:
- mollusces
- crustaceans
- cephalopods
- fish
Population
Their population is now between 9000-12000
Key threats and issues
- slow reproduction of 18 months
- 40-50% of pups die in their first year due to threats such as lobster traps, fishing nets and other larger marine animals

lay on average 4 eggs per nest, however only one on average survives to adulthood

due to expanding farms there isn't enough space for the Cassowary.

- They prey on small marsupials and mammals, most snake, lizards, fish and cats, the eagle is another top-order predator that keeps the balance of the ecosystem in check.
- Its primary threat is its fragile nesting behaviour, in which slight disruptions can scare a female away from her fertilised eggs. This occurs most frequently with human contact. 
-Chickens, geese and small or sick animals are sometimes seen as food options for the eagle, occasionally bringing them into contact with farmers.
