Forest investigation:
Dynamics of forest animals in the hinterland of Seal Rocks, NSW, Australia
Changes over time in the number of
Australian brush turkeys & Superb lyrebirds
in relation to the abundance of Dingoes:

Note the vertical yellow bars are the summer months (blue boxes = winter months).
Key findings (Dec'16):
Australian brush turkeys:
​
​
​
​
-
Brush turkey numbers peaked in any season and varied greatly between years.
-
There appeared to be no clear relationship between peaks in turkey numbers and peaks in dingo abundance.
-
Turkey numbers were at a record low just before the major pulse in dingo abundance within and about the 2014-15 summer. Turkey numbers then steadily increased suggesting little influence arising from this record pulse in dingo abundance.
-
Accordingly, there is little evidence that pulses in the abundance of dingoes negatively affect brush turkey numbers.
Superb lyrebirds:
​
​
​
​
-
Lyrebird numbers peaked in any season and varied greatly between years.
-
After the major pulse in dingo abundance within and about the 2014-15 summer, lyrebird numbers appeared little affected. However, there is a suggestion that their numbers actually increased and reached a higher more stable level.
-
Accordingly, there is little evidence that pulses in the abundance of dingoes negatively affect lyrebird numbers.
