Fungi Foray Report

On Sunday May 9th we held a fungi foray starting at Bulga Park. The conditions were favourable and we had a great turn out with 30 people signed up and ready to go at 9.30am. After an introductory presentation we set off for a very slow loop down to the suspension bridge, returning via the Fern Gully and Link Tracks. Understandably some families with small children and others with Mother’s day lunch commitments dropped out along the way, but even on a short walk they would have experienced a wide variety of fungi displaying their spore bodies.

It has been a big job documenting the finds, between my daugher and I we have added over 170 sightings to iNaturalist for the day https://www.inaturalist.org/projects/tarra-bulga-national-park This includes sightings from the Tarra Valley (I couldn’t resist checking out what fungi could be seen there as I was going past on my way home). Overall the total species recorded to date is 68! I wonder if anyone that attended has got photos of species that we missed? Anyway enjoy the gallery below which contains some examples of the variety of fungi seen on the day.

Bioblitz – Sunday February 14th

For anyone that is interested, Friends of Tarra-Bulga National Park are going to hold a Bioblitz on Sunday February 14th. The day is intended to be a fun and casual way to start off our activities for the year. We will aim to use cameras to record anything of interest we find. The results can then potentially be added to Citizen Science apps such as the Tarra Bulga National Park project on iNaturalist https://www.inaturalist.org/projects/tarra-bulga-national-park . If the weather conditions are suitable, we will also run a light sheet to attract moths and other insects on the Sunday evening. 

Anyone is welcome to attend, no prior experience or knowledge is necessary. The official start time is 10am at the Visitors Centre but you could potentially join in at any time on the day. Just bring along any food or drinks you need for the day as well as any cameras, phones, binoculars etc you may have lying around. For more information or to register your interest in attending you can contact 0488 035 314 or email: friendsoftarrabulga@gmail.com You can also register via ParkConnect https://bit.ly/39VtMRV

Kara Healey’s – Collection of Mosses and Liverworts

One of the stunning features of Tarra-Bulga National Park’s cool temperate rainforest gullies is the amazing array of mosses and liverworts. These delicate plants are often tiny and identifying them can be a significant challenge. Kara Healey was a renowned caretaker(Ranger) in the Tarra Valley in the 1950’s. She dedicated a lot of her time to collecting specimens of a wide range of lifeforms in within the park and sending them off to herbariums and other institutions to be identified and catalogued. Her efforts resulted in the Tarra Valley having one of the most comprehensive lists of its flora and fauna out of any park in the state. We have recently obtained some scans of collections she made way back in the 1950’s. It is incredible that they are so well preserved after all this time. Enjoy! and for anyone who is into studying mosses and liverworts out there – this might be a very useful resource.

2019 Lyrebird Survey Results

Conditions were fortunately very good after a wild week of strong winds, rain and even a dusting of snow on the Wednesday. As a result  of the snow many fern fronds have been crushed down and were providing an obstacle along the walking tracks. The temperature was relatively mild and although you could hear the wind in the tree-tops it was not that strong. First Light was predicted at 6:52 am and the official sunrise time was 7:21.

We had 38 volunteers which was more the enough to cover all 16 monitoring locations. After meeting at 6.15 am everyone was briefed and out into the field by 6:40. Kookaburras were the first birds to start calling and were very active and noisy for quite a while. It seemed like quite a long wait until we heard our first Lyrebird at 6:58 am. Most volunteers had vacated their sites by around 7:15 am and people started filing into the Guest House for breakfast by about 7:25.

The results were collated this year during Google Earth.  The bottom of Lyrebird Ridge seemed to be quite active as well as the points around the suspension bridge and the Bulga Carpark. other sites were much quieter with only one or two calls heard.

Using our call triangulation method there ended up being a couple of anomalies with the results that made the certainty of the existence of a couple of birds 100% certain. (e.g  2 monitoring sites heard it calling but a closer one did not). Overall though we came up with a total of 9 birds calling for 2019 (which is one more than last year).

Working Bees Switching to Sundays

This year we are switching to hold most of our on-ground activities on Sundays. The first one is coming up this Sunday morning (March 31st). We will be meeting at the Tarra Valley Carpark at 9.30am and then heading down to our project site a bit further down the road where we will spend a couple of hours hand weeding sycamore maple, ivy and tutsan.
BYO, gloves etc but please let us know via friendsoftarrabulga@gmail.com or phone 0488 035 314  if you intend to come along in case any plans need to change on the day.

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%.

Percentage of Cats0.7%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. (For a summary of sightings of others species download this Percentage of sightings per year for commonly detected species captured in remote camera photos )

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.
