One area of the park that the Friends of Tarra Bulga are monitoring carefully is an area that has been set back by the occurrence of the Black Saturday bush-fires. The site is on a north-west facing slope and is an area of about 10 ha.It was added to the National Park in 1986 which was part of the process of the merging of the Bulga Park and Tarra Valley reserves. At that time it was in very poor condition, having being abandoned after being cleared for farming. It was reportedly covered in blackberries, introduced grasses and native colonisers such as Fireweed Groundsel and Bracken Fern.
The Friends of Tarra Bulga planting day last Saturday was a great event, which will hopefully result in the return of some towering wet forest in years to come. It will also greatly assist efforts to prevent the re-infestation of Sycamore Maple trees into this area of the National Park.
Volunteers managed to plant 600 Mountain Ash (Eucalyptus regnans) species across the site, which was no mean feat given that each plant needed to be carefully placed in a position where they will be guarded from browsing by hungry Swamp Wallabies. This involved scrambling over steep areas thick with fallen branches, while trying to avoid human hazards such as stinging nettles and leeches. While this may sound arduous there were no complaints from the willing and enthusiastic volunteers happy to be out making a difference to the park and enjoying the scenic (but muddy in spots) walk into this secluded planting site.
The group will now carefully monitor this site over the coming years to check that the newly planted trees are growing successfully and retreat any Sycamore Maple regrowth that sprouts from the treated stumps and pull out any new seedlings that pop up. Funding for this project has been supplied by the Victorian Government’s “Communities for Nature” Program.
Friends of Tarra Bulga have a big new project and we are looking for some enthusiastic helpers to get things off to a great start. A couple of years back a huge infestation of Sycamore Maple trees, which can grow up to 30m tall, was discovered in the park. These trees produce winged seeds which can spread in the wind, so the plant has the potential to invade further into the surrounding Mountain Ash forests.
Contractors were used to cut down the Maples and poison the stumps, and the result so far has been a big success. The canopy has opened up and native understorey plants are taking advantage of the light and space and popping up everywhere. To be a complete success however and to help prevent re-growth of the Maple, canopy species such as Mountain Ash need to be re-established. The friends group has secured funding from the Victorian Government’s, Communities for Nature Grants to do this and are holding a planting day on Saturday August the 11th.
The friends are keen for as many helpers are possible on the day but please note the task is a bit of a challenge. Access to the site is 2.5km along a walking track from the nearest road. The planting site itself is covered in logs and branches of what remains of the dead Sycamore Maple trees. While these branches are an obstacle we also plan to use them to our advantage, by planting amongst them we hope they will act as natural tree guards, keeping the new seedlings out of reach of hungry Swamp Wallabies that are notorious for eating newly planted trees. So if you are ready willing and able please come along. The meeting spot will be at the Tarra Bulga Visitors Centre Carpark at 9am on Saturday August the 11th.
