This weekend camp was on a reserve owned and managed by Bush Heritage
Australia located 12 km north west of Wedderburn. Results were partially
successful in so far that a single Southern Freetail Bat Mormopterus species 4 (undescribed) was captured, but otherwise
disappointing regarding terrestrial and arboreal mammals. This bat was one of
three mammal species Jeroen van Veen, Bush Heritage's Field Officer at Nardoo
Hills Reserves, was hoping for us to find on the reserve; the other two not
found being Fat-tailed Dunnart and Sugar Glider.
In addition to the Southern Freetail bat, 10 Little
Forest Bats Vespadelus vulturnus and
5 Lesser Long-eared Bats Nyctophilus
geoffroyi were captured after 10 Harp Trap nights over three nights, 16
bats in all. No mammals or any other
fauna were recorded by eleven MSGV remote sensing cameras deployed over three
nights for a total of 24 camera nights. All 49 nest boxes installed by MSGV in
2006 were empty. No cage or Elliot traps were set.
Spotlighting revealed 6 Ringtail Possums, 15 Brushtail Possums and a
single Eastern Grey Kangaroo on two surveys; one over a short distance near our
camp site and the other along a two kilometre section of Mt Kerang road in
Wychitella Nature Conservation Reserve immediately east of Nardoo Hills. Of these, only 2 Brushtail Possums were
spotted within Nardoo Hills Reserves, the remainder were in Wychitella
NCR. An interesting aspect to this, as
explained by Jeroen has a lot to do with past land use. In the case of the three blocks that make up
Nardoo Hills, all were previously grazing properties resulting in significant
loss of ground cover vegetation and shrub layer. In the case of Wychitella NCR the area was
selectively logged in the past without deliberate removal of shrubs and ground
cover. It appears from this spotlight survey that past logging has had much
less impact compared to grazing in this area regarding arboreal mammals.
Other mammals seen or heard over the long weekend include
a small number of Eastern and Western Grey Kangaroos (about 10 of each) and 2
Black Wallabies. Of the 55 species of birds recorded White-browed and Masked
Woodswallows were the highlight. All the other species recorded are what would
be expected to occur in this reserve.
Reptiles seen include two skinks, Morethia
boulengeri and a Jacky Lizard.
