Hi Ralph
Sarah Tassell (University of Tasmania) is currently conducting her Ph.D on
Superb Lyrebirds in Tasmania:
Sarah Tassell - The impact of the superb lyrebird (Menura novaehollandiae)
on Tasmanian forests ecosystems (Doctorate)
The superb lyrebird was introduced to Tasmania in the 1930s and 40s in order
to save the bird from the perceived threat of foxes and habitat loss on the
mainland. However, there is growing concern that lyrebirds may pose a threat
to Tasmanian forest ecosystems.
Lyrebirds feed on invertebrates by scratching over large amounts of leaf
litter and soil. Their roles as a predator and as a bioturbating ecosystem
engineer mean that lyrebirds are probably a keystone species in the forests
they inhabit. Since there is no native equivalent to lyrebirds, Tasmanian
flora and fauna may significantly affected by their activities.
General project aims:
1. To examine the impact that lyrebirds have on leaf litter and soil
invertebrate communities both directly through predation and indirectly
through changes to habitat brought about by foraging.
2. To determine whether bioturbation and damage to individual plants caused
by foraging affects vegetation communities.
3. To establish the impact that foraging activity has on soil and leaf
litter structure and function.

Hi all,
The Wikipedia entry reported by Stephen Ambrose says that the Superb
Lyrebird was successfully introduced into Tasmania.
Has anyone recorded any recent (i.e. last 5 years) Tasmanian sightings?
Also, was it introduced or re-introduced?
Regards
Ralph Reid
