Without any advanced statistical scrutiny strong trends include:Our remote camera monitoring has now reached four solid years of records. Although not a flawless scientifically planned project there are still be some interesting developments. The table above shows the total sightings of each species combined across all of the camera sites. There are many variables in these results, the main one being that cameras have been moved around different habitats at different times, so have not constantly been in the one place.

  • A massive rise in the number of Brush Bronzewings every year.
  • A rise in the number of other ground dwelling bird species including Bassian Thrushes, Pilotbirds, Eastern Whipbirds and Common Blackbirds.
  • An increase in the number of Long-nosed Bandicoots (although this may be explained by moving cameras to areas where habitat is more suitable).
  • Crimson Rosellas had a huge spike in numbers in 2014 (maybe because there was a lot of wattle seed on the ground?)
  • An upward trend in Echidna and Feral Cat numbers.
  • A drop in Fox numbers in 2015.
  • 2014 had double the amount of Lyrebird sightings than other years.

Several cameras have been left in the same spot for several years and it is possible to compare the results of these sites with the overall figures.

Site: Tarra Bulga – North East

Comments: The open nature of this site means it is less suited to small mammals. Popular site for Swamp Wallabies to congregate. Openness also suits many ground feeding birds scratching around or eating fallen seeds. Foxes and cats often pass through. Has been a Koala habitually passing the camera every few days between its favourite trees.

 

Site: Balook Area

Habitat: Open forest with regenerating Mountain Ash, Ferny understorey with some thick scrubby patches near by.

Comment: Good site for a diversity of species, some scrubby ground-cover in the area makes it a good spot for Bandicoots, with a high proportion of our Bandicoots sightings recorded here. Also good for introduced Common Blackbirds and Rabbits that like to hide in cover. Like other sites had a big spike in Crimson Rosella numbers in 2014. Interestingly large drop in Fox numbers.

Lyrebird

Lyrebird Numbers Up, Brush Bronze-wing Population Explodes!

Friends of Tarra-Bulga have now been using remote cameras within the park to monitor wildlife for over three years. The table below shows results adjusted for the number of days cameras have been active in the field. We currently have eight cameras that are moved around to different sites on a regular basis. As of January 2015 the cameras had spent a combined total of over 5000 days in the field and were triggered by animal movements over 10,000 times.

Feral Cat with a Sugar Glider
Feral Cat numbers have risen

The results show a number of interesting trends. For mammals most species have not varied much in the frequency of sightings over the 3 years with a few exceptions. There was a large jump in Koala sightings in 2014 most were at one site where a Koala developed a routine of passing by every couple of days. Feral Cat numbers have risen each year and Ring-tailed Possum sightings seem to have declined. (the figures for Ring-tails have been influenced heavily by one popular site).

Lyrebird
Lyrebirds captures by our cameras doubled each year.

There has been a massive jump in the numbers of birds that the cameras are detecting. The number Lyrebirds passing cameras have doubled each year. Bassian Thrush (Zoothera lunulata) sightings increased around 600% in 2014 and Brush Bronze-wing numbers skyrocketed from only 15 sightings in 2013 up to 404. Crimson Rosellas, Eastern Whipbirds, Pilotbirds and *Common Blackbirds all had a significant rise in detection. Two smaller species the White-browed Scrubwren and the Superb Fairy Wren were also ‘captured’ more often.

Brush Bronzewing
We have had massive increase in the number of Brush Bronzewings recorded.

A reason for the jump in bird numbers may be due to camera placement. One site used in 2014 was very popular for ground dwelling bird, however this does not fully explain the rise, other camera sites were used in both years and showed a big increase ground dwelling birds from 2013. Fox control efforts in recent years may also be a factor helping the birds numbers increase. Our results have picked up a small rise in Fox numbers over the last few years. As our monitoring continues, time will tell if this greater abundance of bird sightings will be maintained.

Camera Site Greatly Exceeds Expectations

In February we placed a camera in a new site along the Grand Ridge Rd, in vegetation that was not typical old growth Mountain Ash forest, but rather sad looking regrowth scrub. As a result we didn’t have high expectations as to what fauna we’d find in this habitat. Surprisingly though it’s a very popular spot, especially with ground dwelling birds (must be lots of food) and we obtained some fantastic images. All up the camera was triggered on 165 separate occasions, see the table below for more details)
