We had a fantastic turnout of volunteers, which meant that all 16 sites could be covered with at least 2 volunteers at each site. (This is the first time we have covered all 16 sites since at least 2010).
Weather conditions were ideal (2nd year running) with little or no wind to muffle the sound of calls and it was not really all that cold!
Everyone got out to their respective positions in time; the earliest call was heard at 6.49am and by 6.55am every monitoring station had Lyrebirds calling.
The official sunrise time for Saturday Jun 3rd at Balook was 7.23am and first light was scheduled to appear at 6.53am. So, it seems Lyrebirds are fairly well tuned to begin calling at first light.
From our results, we detected 11 male birds calling, (not sure if it would be possibly with our method to detect two birds calling in close proximity to each other, but a couple of stations noted the possibility that they could possibly hear multiple birds calling from around the same direction.
Note: we only count birds that are detected by at least 2 monitoring stations.
This is our second highest number of birds recorded since at least 2010.
Thanks to AGL who helped to pay for the breakfast.
Don’t miss your chance to be involved with Friends of Tarra-Bulga National Park Annual Lyrebird Survey. This year it will be held on Saturday, June the 3rd. The meeting point for all volunteers is the park visitors centre at 6.15 am. The Survey takes only 30 minutes from the time the sun rises and the birds start calling, Straight after the count a free breakfast for all volunteers will be provided at the Lyrebird Cafe. To secure your place please email firstname.lastname@example.org or call David on 0488035314 by Wednesday 31/5/2017
The Friends of Tarra-Bulga National Park are holding a working bee on this coming Saturday April 29th and are would welcome new or existing volunteers to come along.
The worksite is in a remote part of the park and getting there will involve a scenic 3km walk through beautiful tree-fern filled Mountain Ash forest. The work will involve removing tree-guards from previous plantings and re-using them to plant more over-storey trees.
The meeting point will be the park visitors’ centre at 9am. BYO snacks, drink, gloves. For planning purposes please RSVP to David on 0488 035 314 or email email@example.com
Volunteer help is needed again on the first of our hands on work days for 2017. Environmental weeds are a menace and without extra help from passionate people they can quickly degrade precious habitats. On Saturday March 18th we will be continuing our ongoing efforts to keep Tutsan, Sycamore Maple, Blackberries and Ivy under control at a vulnerable site in the picturesque Tarra Valley.
No experience or prior knowledge necessary (help with weed id provided).
Meet at the Tarra Valley Picnic Area Car Park at 9.30am (finish at 12.30pm)
Tools provided (but you might like to bring along your own gloves.
For further details or to let us know you intend to come along contact us at firstname.lastname@example.org or phone David on 0488 035 314.
This coming Saturday August 27th Friends of Tarra-Bulga National Park will be doing some tree planting. Members of the public are welcome to come along and lend a hand. Meeting point 9.30am at the visitors centre Car Park. For inquiries contact 0488 035 314 or email email@example.com
Renowned for its stunning cool-temperate rainforest, luxuriant tree-ferns and towering Mountain Ash trees, Tarra-Bulga National Park is cherished by Gippslanders and enjoyed by visitors from all over the world. The original separate small, but significant, Bulga and Tarra Valley Parks were reserved just over a century ago while the giant forests surrounding them were being laboriously hand cleared by selectors to turn into farms. Clearing this land turned out to be folly, the terrain, cold winters, bushfires, weeds and rabbits all contributed to the farmers giving up and walking away, leaving scrub and noxious weeds in their wake. Forestry and sawmilling in the area for timber and pulpwood also led to the loss of more of the original giant trees.
In recent years Tarra-Bulga National Park has expanded. New areas including abandoned farmland have been added with the goal of physically linking Tarra Valley and Bulga Parks as well as to reduce visitor pressure on significant sites, provide greater recreational opportunities and protect additional vegetation communities representative of the Strzelecki Ranges. It is recognised that Tarra-Bulga National Park has the potential to become even more spectacular and significant as cleared land is successfully regenerated.
To this end the Friends of Tarra-Bulga National Park are seeking volunteers interested in helping with the regeneration process. The group holds occasional work days on weekends, undertaking activities such as planting over-storey trees and controlling noxious weeds. The next activity is scheduled for Saturday July the 23rd 30th and will focus on removing tree guards from successful new plantings. The meeting point will be at 9.30am at the Visitors Centre Car Park. For further details or to register your interest in helping out Friends of Tarra-Bulga with any of their activities email firstname.lastname@example.org or phone 0488 035 314.
In the pre-dawn darkness on Saturday the 18th of June, twenty-five volunteers and one Park Ranger were greeted with perfectly calm conditions for Tarra-Bulga National Park’s Annual Lyrebird Survey. Overnight showers had passed by leaving moist dripping foliage in their wake.
The survey is designed to monitor the density of Lyrebirds living in 60ha comprising of wet sclerophyll and cool temperate rainforest immediately to the east of the Tarra-Bulga National Park Visitors Centre. There are sixteen monitoring points strategically placed throughout the site and volunteers move to each site before adult male Lyrebirds start their morning calls at dawn. Volunteers then use a compass to record the direction and proximity of the Lyrebird calls. This year we had enough volunteers to cover all but one of the monitoring points.
Following the survey, lines representing the direction of the calls are plotted onto a map, and triangulation is used to establish the spots where birds were calling from. This year the results indicate we had at least nine (male) Lyrebirds calling in our 60ha zone. This corresponds to a density of one adult male Lyrebird per 6.7 ha. You can also assume that there will be female lyrebirds and immature males or non-calling males within our target area. To account for this to get our overall population of Lyrebirds we multiply the number of calling males by a factor of 2.5. It is believed that male Lyrebirds do not begin to breed until they are around 6 or 7 years old.
