Excursion to Southern Forests lyrebird habitat, August 2000
|
Lyrebirds were introduced into Tasmania in the 1930s and 1940s because of fears for their extinction from fox predation on mainland Australia. Since then their range and population size has expanded dramatically, now extending close to an 80 km diameter. Their impact on invertebrates and other food sources (as in this display mound) is currently being investigated by a student at the University of Tasmania, but from the soil disturbance it would be impossible not to think that a major impact is occurring. |
