The Persistence of Abrus
One of FIDO’s many inspiring volunteers has been Peter Dorney, a nurseryman from Boreen Point. Pete was appalled by the extent and aggressiveness of the rampant Abrus he encountered during a Happy Valley working bee in March 2016. He wondered how persistent the seed might be because this is critical to how long the vigilant treatment of Abrus needs to be maintained once no more seeds are set. (more…)
Fraser Island Pandanus Rescue
Joel Fostin has launched Fraser Island’s first ever crowd-sourcing campaign. Can you help?
Fraser Island (K’Gari) has suffered catastrophic losses. Up to 50% of the east coast’s Pandanus have perished (approximately 50,000 plants). A further 20% are likely perish without intervention within the next two months. Preserving the remaining Pandanus is crucial for successful natural regeneration, and vital for the many species of wildlife that rely on them for food and habitat. The Pandanus on Fraser Island (K’Gari) need help right now. (more…)
Round Island Weeding Update
Round Island is managed by Fraser Coast Regional Council. Because of the island’s close proximity to the mainland, it is frequently visited by both locals and tourists.
Two trips (26 July & 23 September 2016) have been made to Round Island this year, the first by two council officers, twelve Lower Mary River Landcare (LMRL) members and community volunteers and a group of twelve from Conservation Volunteers Australia. The second trip included council officers and volunteers with chemical spray certificates (AC/DC) as the trip targeted weeds that required chemical treatment.
These one-day weeding efforts, conducted over the last 4 years, have resulted in a highly significant benefit to this very small, coral sand island of dunal system environment. With the assistance of Juliet Musgrave, her skills and knowledge, the identification of some of the native plants (e.g. Octopus Bush) on Round Island demonstrates that this area is the overlap of vegetation zones on the coast between sub-tropical and tropical. To date, more than 30 native plants have been identified and registered, and the list grows each visit the group makes. (more…)
Happy Valley Weeding Update
This trip the focus was again on the invasive weed Abrus precatorius subspecies Africanus (Common name – crab’s eye). The control program began in March 2014, with four trips a year since then. The population was extensively established on the Northern, Western and Southern sides of the village, as well as throughout the village area. It has not been detected East of the village. The plant is a creeper/climber, and in many areas, had occupied up to 70% to 80% ground cover and extended into the canopies of trees. It seeds in all areas where it grows, and profusely when it gets high levels of sunlight exposure, such as on the dingo fence and especially where it extends into the canopy of trees.
After trialling physical removal, including attempts to dig the roots out, and cut and paste with roundup, it became very clear these methods were ineffective and, given the extent of the infestation, were completely impractical. Foliage spray was trialled with glyphosphate and starane. Both chemicals resulted in good knock down of foliage, but with starane, plants regrew from the roots. Glyphosphate (1.5% Roundup) applied with a wetting agent and a dye is the mix we now use. It is extremely effective. (more…)
New Biosecurity Act
As of 1 July, a new Biosecurity Act now encompasses the previous Land Protection Act. Focused on risk-based management and on the likelihood and consequences of the risk of spread, this broader Act will continue the management of invasive plants and animals throughout Queensland. All Queenslanders, individuals and organisations have a general biosecurity obligation to take reasonable steps to report and ensure they do not spread a pest, disease or contaminants. (more…)
National Standards for Ecological Restoration
The National Standards for the Practice of Ecological Restoration in Australia have just been released by the Society for Ecological Restoration in Australia (SERA) board’s Principles and Standards Reference group in close collaboration with partners and advisors.

Fighting Triffids
Peter Shooter continues to lead his teams of FIDO volunteers in their never-ending war against the very aggressive and invasive African subspecies of Abrus prectorius.

Green Army Battles for K’Gari’s Natural Integrity
Work is underway in Fraser Island World Heritage area by the first 9-person Green Army team, which includes three young Butchulla men. Despite encountering hold-ups in gaining approval for overnight residence on the island, as well as delays in beginning training, the Green Army team is being kept busy with the important tasks of removing rubbish, lantana, groundsel and other weeds from the main entry road near the Wanggoolba ferry landing, and lantana control in Dundubara creek.
As they return each week as part of their six-month program, every member of the team is gaining a greater familiarity with Fraser Island (K’gari) and personally benefitting from the training and experience they are receiving. As part of their work, the Green Army team has received training in safe chemical use, as well as fencing construction and deconstruction. They have been using these new skills to contribute to K’gari’s natural integrity.
It is hoped that as the program progresses, the productivity of future teams will benefit from overcoming the challenges that any new partnership arrangement must face (especially for an area as significant as the Fraser Island World Heritage Area). In this way, we hope that the CVA Green Army teams will be an ongoing presence on Fraser Island and will be able to make an even greater contribution to weed and erosion control in some very critical areas of K’Gari.
Work Continues on George Haddock Track
Track clearing was done manually, with little assistance other than from battery-operated chainsaws to deal with larger tree-falls across the track
Over the 2016 Easter weekend, 16 volunteers helped to honour FIDO’s obligation to maintain the George Haddock Track. The team cleared 17 km of track of fallen timber and major regrowth. During 2014, FIDO and National Parks Association of Queensland volunteers cleared 22.7 km of walking tracks along former logging tracks and roads in nine different sections of the 52 km George Haddock Track, supported by a Friends of Parks grant. No maintenance had been done since October 2013, except for a little clearing between Lake Coomboo and Hidden Lake.
During these latest clearing efforts, the swathe of cleared ground around the Harold Charles Barracks was greatly extended by stripping away regrowth and accumulated fallen debris. This will provide critical infrastructure with a greater safety margin from potential fires. It also created a larger flat area for campers participating in future working bees.

Call for Volunteers to work on K’gari, Second Half 2016
FIDO has been conducting week-long working bees to tackle the urban weeds of Fraser Island for more than a decade. With support of other organizations aiming to improve the natural integrity, FIDO is determined to bring the urban weeds in the townships of Eurong and Happy Valley under control. (more…)
