Figure 25.3 Locations <strong>of</strong> five maremmas (highlighted in pink) when a wild dog foraged in their<br />

sheep paddock<br />

Interbreeding<br />

DNA analysis <strong>of</strong> blood samples taken<br />

from wild dogs showed no evidence <strong>of</strong><br />

interbreeding between maremmas and<br />

wild dogs on Dunluce Station. However,<br />

all working maremmas on Dunluce<br />

Station are desexed or treated to prevent<br />

interbreeding.<br />

Biodiversity impacts<br />

The activity <strong>of</strong> rodents and birds (likely<br />

prey for feral cats and foxes) was similar<br />

for both sheep and cattle paddocks and<br />

was independent <strong>of</strong> the activity <strong>of</strong> foxes,<br />

maremmas and wild dogs. Fox and wild<br />

dog activity fluctuated between surveys,<br />

but these animals were mostly detected<br />

in the sheep–maremma paddocks rather<br />

than the cattle paddocks. No wild dogs<br />

were detected during the July survey<br />

(at whelping), yet tracking showed they<br />

were still making incursions into the<br />

area at this time.<br />

In April 2011, we captured and collared<br />

eight wild dogs and six maremmas<br />

on Stratford Station. We will conduct<br />

wildlife surveys and DNA analysis <strong>of</strong><br />

wild dogs similar to those on Dunluce<br />

Station.<br />
