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…)

Treatment of Planthopper on Pandanus

Over 8–11 June, members of the Lower Mary River Land and Catchment Care Group, Don Bradley, Lesley Bradley and Janet Price, treated 160 Pandanus plants at Kingfisher Bay Resort and Beach Front against infestation by Jamella australiae (Pandanus Planthopper). An effort was made to locate all plants at the resort.

In addition to the 160 plants treated, 25 plants were found to be infected with Jamella, including three in very poor condition; a further three dead plants were found. Treatment was with 50% Confidor, and involved injecting trunks and low braches, or in the case of smaller plants, spraying leaves and squirting the crowns. Size of tree and type of branching determined the number of injections per tree: trees head high received one injection; taller, single trunk trees received two injections; trees branching up high received three injections; and large trees branching received two injections per branch where branches could be reached. Infected trees were marked with blue paint.

Funding for this project was supplied by a BMRG-Chemical grant, and thanks go to QPWS for supplying the Sidewinder tool and training for the injections, and to Kingfisher Bay Resort for providing barge passes and accommodation.

Using Bufo Toxin to Control Cane Toads

An innovative scientific trial using cane toads’ own defense mechanism (bufo toxin) against their own spawn could bring about the eradication of these pests from Fraser Island. (more…)

In search of “Broad-leaf Pepper”

By Vanessa Elwell-Gavins

As a complete newcomer to Hervey Bay and Queensland (from Tasmania), this trip to Round Island (a follow-up to a weed working bee six weeks earlier) was my first exposure to the task of managing environmental weeds in a sub-tropical environment.  (more…)
