Southern Cassowary, Casuarius casuarius johnsonii
Problem:
Clearing of tropical
rainforest has divided the Southern Cassowary population into several small,
fragile remnants. In these patches of forests, cassowaries are susceptible to a
range of threats (starvation, dog attack, shooting, and road accident) that are
normally not as big a problem in larger areas of suitable habitat.
Background Information:
The Southern Cassowary
is Australia's second largest bird, and probably its most spectacular. It is
being killed off by land clearing and habitat fragmentation, predation by dogs,
road accidents and accidental capture in pig traps.
Research:
CSIRO, Joan
Bentrupperbaumer and the Consultative Committee on Cassowary Conservation (CCCC)
have researched the reasons for decline in cassowary numbers and have
recommended rescue measures. They have highlighted the cassowary's role in
spreading the seeds of over 100 types of rainforest trees. Rainforest plant
diversity and homogeneity may depend on the presence of cassowaries.
Solution:
Retain core habitat
that already exists. Re-establish interconnection between habitat fragments.
Rehabilitate degraded habitat. Develop strategies to deal with road deaths,
agricultural expansion, pigs and dogs.
