Monitoring

We currently have a number of ongoing monitoring programs which are important to our knowledge and the health of our wonderful National Park and we are keen for more FoBR members to get involved.

All the fauna monitoring activities are done to improve our awareness of the biodiversity in the Brisbane Ranges. The program gives members a unique opportunity to become involved, improve their own skills and knowledge and enable them to teach others about the natural values in the Brisbane Ranges.

Our mammal monitoring activities have been approved by the Animal Ethics Committee and we have DSE Research Permits for these.

In 2010, only 2 Agile Antechinus were monitored at one location. In 2012, 16 Agile Antechinus and 6 House Mouse were found across 3 locations.

Remote Cameras

In May 2012 the Friends group purchased 3 infrared cameras for fauna monitoring. The cameras are usually positioned on a tree with a bait station located just in front. The bait is a mixture of peanut butter, oats and golden syrup. Fish oil is sometimes used as well. Animals have no access to the bait and are lured by odour only. Cameras are left in position for 2-3 weeks.

Sightings include kangaroos, wallabies, deer, Brush Tailed Possums, rats, mice, foxes, wombat, birds and Brush-tailed Phascogales.

One camera is located inside a box designed to only permit the entry of small mammals. However, the short length of the box meant that the focus was poor and positive identification of the smaller animals was difficult. Close range focus has been improved by placing a lens from a pair of reading glasses in front of the camera lens.

Reptile Survey

Reptile monitoring data for the Brisbane Ranges National Park is extremely sparse and old, with most records dating from 1960-1980. We are planning to set up and monitor reptile survey grids using roof tiles in the Park. Several grids will be set up and monitored over several years, in order to determine the occurrence and distribution of reptiles and possibly amphibians.

Bird call monitoring

Colin has been plugging away at a project to use digital sound recorders to record bird calls, then using SongScope call recognition software to process the field recordings and identify birds of interest. I’ve processed known calls to build call recognition files for 93 of the 188 birds found in the Brisbane Ranges. Over the next few months we’ll get some field recordings and hopefully start to monitor some of the more cryptic bird species. The system can also be used for frog and animal calls, so we may get some useful data on these fauna too.
