"The dry conditions in Melbourne, and the fact that we do not water our
gardens any more, may well be the reason that Song Thrush numbers have
dropped in Melbourne."
Other factor would be urban infill/higher urban density, and resultant loss
or shrinking of house block gardens. While sadly this is not great for urban
wildlife, I support it as it helps control urban sprawl.
The current massive growth around Melbourne in the Werribee, Hume and Epping
corridors, often in previous Green Wedge areas, is horrendous. Large areas
of very rare and significant remnant vegetation is being destroyed, in
particular Western Basalt Plains Grassland and Red Gum Grassy Woodland.
Habitat to many rare and endangered animals and plants. Infrastructure
development to support this sprawl further exacerbates the habitat loss not
to mention the other adverse environmental contributions (e.g. more roads -
greenhouse)
