Mulgara - Habitat
Mulgara
inhabit the hot, arid, sandy regions of Australia from southern
Queensland through the Northern Territory to Central Western Australia.
(see distribution)
Spinifex is the main vegetation in this area, specifically Triodia basedowii,
which provides refuge from the heat and cover for the entrance to their
burrows.
These burrows are usually in the flat areas between sand dunes or on the
low sides of the dunes. They can often be close to other Mulgara
burrows. They can vary in complexity from burrows with single entrance
holes and minimal tunnels to multi entrance holes with many and deeper
tunnels and branches. These tunnels will also often have numerous pop
holes depending on location.
Mulgara
are predominantly nocturnal and so will retreat into their burrows to
escape the heat of the day particularly in summer, although they have
been observed to be taking in the warmth of the sun during cold winter
days.
Mulgara tend to maintain a permanent home rather than migrating to
follow food sources, so a permanent cover of Spinifex is important not
only in providing refuge and homes, but also habitat for prey species
and the ability to move around to hunt those species. Therefore the
burning of the Spinifex, whether through natural or man-made fire, poses
a real threat to the Mulgara.
Even
when rainfall is low, Mulgara tend to stay put and regulate their
population to take the lack of water and thus food sources into account.
