Fire damaged re-vegetation.
Project Site in 2010, previous re-vegetation efforts were destroyed in the Black Saturday fires.

 

This Saturday July 28th, we are inviting people to join us

New Seedling

Meeting point is the Tarra-Bulga Visitors centre at 10am and the activity will finish around 1pm. Please let us know if you intend to come along in case there are any change of plans. Phone 0488 035 314 or email: friendsoftarrabulga@gmail.com

Lyrebird Mound in the Tarra Valley

Thanks to group members Martin and Bernadette for letting us use this great camera footage they captured from a very busy Lyrebird mound just near the park in the Tarra Valley. The video catches a male Lyrebird at the peak of the breeding season, strutting his stuff in a full display.

Cats in Tarra-Bulga National Park

Although they are not often seen by visitors, feral and domestic cats are established predators at Tarra-Bulga National Park and our remote camera results suggest they are becoming more common.

The table below shows results from five years of remote camera monitoring carried out by the Friends of Tarra-Bulga Park. Cat numbers as a percentage of total species recorded rose dramatically from 0.7 to 3.9%.

Year 2012 2013 2014 2015 2016 2017
No. of Cats Records 16 33 64 59 41 64
Total Records 2208 2898 4827 3804 1352 1638
Percentage of Cats 0.7% 1.1% 1.3% 1.6% 3.0% 3.9%

The impact these cats are having on the birds, small mammals and reptiles is a real concern. Although there are many variables in the ways we set up our cameras, the general trend in the last few years is for them to be detecting greater numbers of cats and less small native mammals (e.g. Antechinus and Bush Rats). Sadly we have also been detecting less of the smaller birds such as Pilotbirds and White-browed Scrubwrens.

The gallery below shows that cats in Tarra-Bulga range from large ferals and panther look-alikes to small (some might say cute) looking kittens, some even have collars. What is undeniable though, is that their presence has a major impact on the ecology of Tarra-Bulga National Park.

 

Ennominae

Ennominae are a sub-family of Geometridae. They include tribes Nacophorini (Satin Moths) and Boarmiini (Bark Moths) as well as a number of other smaller tribes.

 

Geometrinae Moths – Emeralds

The common name (Emeralds) for this Sub-family of moths derives from the fact that many of them are Blue-green in colour.

 

Larentiinae – Carpet Moths

Larentiinae moths are a sub-family of Geometridae. They are commonly known as Carpet Moths. 28 separate species of Larentiinae have been recorded in Tarra-Bulga National Park.

 

Hepialidae (Ghost Moths)

To date we have 5 different species of moths in the family Hepialidae recorded in Tarra-Bulga National Park.
