  • Botanical Name. Acacia
    Botanical name Acacia colletioides Benth., London J. Bot. 1: 336 (1842) The botanical name is derived from Colletia (a genus in the family Rhamnaceae) and the Greek suffix -oides (like). Some species referred to Colletia have a resemblance to the spiny, rigid foliage of this Acacia. Common names Wait-a-while, Pin-bush, Spine Bush. Characteristic features Large, prickly, much-branched shrubs. Phyllodes +/- terete, sessile, rigid, straight to shallowly curved, widely spreading, finely 8-nerved (with a distinct inter-nerve space between each nerve), narrowed to needle-like points. Heads sub-globular on short peduncles. Pods strongly curved to openly coiled or twisted. Seeds black and 2/3 sheathed by a conspicuous, orange or yellow aril. Description Habit. Harsh, rigid, prickly, much-branched, dense, rounded, usually multi-stemmed shrubs (0.5)1-3 m tall and about the same across, maturing to single-stemmed small trees 3-4 m tall with a dense canopy occupying 50% of the total plant height, in open sites (e.g. roadverges) it grows as a domed plant with the canopy extending to ground level, in dense vegetation it can grow as a small, erect plant with spindly stems and non-spreading crowns (however, these forms are not common in the Kalannie region). Branchlets. Glabrous or sparsely hairy, scarred where phyllodes have fallen. Phyllodes. More or less terete, sessile, inserted on distinct, yellow stem projections, 1.5-3(-4) cm long, 1-1.5 mm in diameter, rigid, widely spreading, straight to shallowly curved, green, glabrous; longitudinal nerves 8, widely spaced and distinct; apices narrowed to rigid, needle-like points.

Background Bellevue Gold Ltd (Bellevue Gold) is currently undertaking an exploration drilling program within mining tenement M3625 for the Bellevue Gold Project (the Project). The Project is located in the north-eastern Goldfields; approximately 40 km north of the township of Leinster in the Shire of Leonora. The Project is situated on and surrounded by pastoral lands and is located on Yakabindie cattle station. RPS was commissioned by Bellevue Gold to undertake a detailed flora and vegetation assessment over M3625 and part of M3624 to encompass the area where exploration drilling is currently underway and including the potential mining and associated infrastructure footprint (the proposed development area). The survey area, the proposed development area and the PoW 79431 area are shown in Figure A. RPS understands that the Department of Mines, Industry Regulation and Safety (DMIRS) and the Department of Biodiversity Conservation and Attractions (DBCA) have requested additional information regarding the natural values of the PoW area, where in-fill drilling is proposed, in order to adequately assess the PoW application.

  • Consultation Document on Listing Eligibility and Conservation Actions Atriplex Sp. Yeelirrie Station
    Consultation Document on Listing Eligibility and Conservation Actions Atriplex sp. Yeelirrie Station You are invited to provide evidence about: 1) the eligibility of Atriplex sp. Yeelirrie Station (L. Trotter & A. Douglas LCH 25025) for inclusion on the EPBC Act threatened species list; and 2) the necessary conservation actions for the above species. Evidence from experts, stakeholders and the general public are welcome. Responses can be provided by any interested person. Anyone may nominate a native species, ecological community or threatening process for listing under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) or for a transfer of an item already on the list to a new listing category. The Threatened Species Scientific Committee (the Committee) undertakes the assessment of species to determine eligibility for inclusion in the list of threatened species and provides its recommendation to the Australian Government Minister for the Environment. Draft information for your consideration of the species eligibility for listing in the Vulnerable category (criterion 1) or Critically Endangered category (criterion 2) starts at page 3 and information associated with potential conservation actions for this species starts at page 8. To assist with the Committee’s assessment, the Committee has identified a series of specific questions on which it seeks your guidance at page 9.

The relative timing between the origin of an insect lineage and the plant clade they eat or reproduce on is important for understanding how host-range expansion can lead to resource specialisation and speciation. Path and stepping-stone sampling are used in a Bayesian approach to test divergence timing between the origin of Acacia and colonisation by thrips. The evolution of host-plant conservatism and ecological specialisation is discussed. Results: Results indicated very strong support for a model describing the origin of the common ancestor of Acacia thrips subsequent to that of Acacia. A current estimate puts the origin of Acacia at approximately 6 million years before the common ancestor of Acacia thrips, and 15 million years before the origin of a gall-inducing clade. The evolution of host conservatism and resource specialisation resulted in a phylogenetically under-dispersed pattern of host-use by several thrips lineages. Conclusions: Thrips colonised a diversity of Acacia species over a protracted period as Australia experienced aridification. Host conservatism evolved on phenotypically and environmentally suitable host lineages. Ecological specialisation resulted from habitat selection and selection on thrips behavior that promoted primary and secondary host associations. These findings suggest that delayed and repeated colonisation is characterised by cycles of oligo- or poly-phagy.
