Approved Conservation Advice for Homoranthus Prolixus This conservation advice was approved by the Minister / Delegate of the Minister on 3 July 2008 Approved conservation advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Homoranthus prolixus This Conservation Advice has been developed based on the best available information at the time this conservation advice was approved. Description Homoranthus prolixus, Family Myrtaceae, also known as Granite Homoranthus, is a prostrate spreading shrub that grows 0.3–0.8 m high. Leaves are 3–6 mm long, 0.5–1 mm wide with a tapered tip and dull blue-green colouring. Flowers are yellow to red and occur in groups of 1–6 at the upper part of the branches. There are multi-cellular hairs between the ribs on the flowers’ outer surface (Craven & Jones, 1991; Harden, 2002; DECC, 2005a). Conservation Status Homoranthus prolixus is listed as vulnerable. This species is eligible for listing as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as, prior to the commencement of the EPBC Act, it was listed as vulnerable under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). Homoranthus prolixus is also listed as vulnerable under Schedule 2 of the Threatened Species Conservation Act 1995 (NSW). Distribution and Habitat Granite Homoranthus occurs in northern NSW in six populations between Inverell and Bendemeer, and is conserved in The Basin Nature Reserve and Goonoowigall Bushland Reserve (Craven & Jones, 1991; NSW NPWS, 2004; Copeland et al., 2007). This species has a localised distribution and the population abundance ranges from frequent to locally abundant. A site north east of Bendemeer has about 300 healthy plants across two rocky outcrops, however other sites have fewer than 30 individuals (DECC, 2005a). Granite Homoranthus grows in heath on skeletal soil among crevices in granite outcrops (Craven & Jones, 1991). Associated vegetation includes Acacia neriifolia, A. granitica, Olearia elliptica, Cryptandra amara, Callitris endlicheri, and Eucalyptus dealbata (DECC, 2005a). This species occurs within the Border Rivers–Gwydir and Namoi (NSW) Natural Resource Management Regions. The distribution of this species overlaps with the “White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland and Derived Native Grassland” EPBC Act-listed threatened ecological community. Threats The main identified threats to Granite Homoranthus are clearing and fragmentation of habitat; browsing and trampling by feral goats (Carpa hircus) and pigs (Sus scrofa); trampling by bushwalkers; road construction and maintenance; frequent fires; weed invasion; and localised extinction due to small populations with scattered distribution (DECC, 2005a). Research Priorities Research priorities that would inform future regional and local priority actions include: • Design and implement a monitoring program. Homoranthus prolixus Conservation Advice - Page 1 of 3 This conservation advice was approved by the Minister / Delegate of the Minister on 3 July 2008 • More precisely assess population size, distribution, ecological requirements and the relative impacts of threatening processes. • Undertake survey work in suitable habitat and potential habitat to locate any additional populations and notify DECC of any new records (DECC, 2005a). Regional Priority Actions The following regional priority recovery and threat abatement actions can be done to support the recovery of Granite Homoranthus. Habitat Loss, Disturbance and Modification • Monitor known populations to identify key threats. • Monitor the progress of recovery, including the effectiveness of management actions and the need to adapt them if necessary. • Identify populations of high conservation priority. • Ensure road widening and maintenance activities (and other infrastructure or development activities) involving substrate or vegetation disturbance in areas where Granite Homoranthus occurs do not adversely impact on known populations (DECC, 2005a). • Investigate further formal conservation arrangements, management agreements and covenants on private land, and for crown and private land investigate inclusion in reserve tenure if possible. Invasive Weeds • Develop and implement a management plan for the control of Coolatai Grass (Hyparrhenia hirta) in Goonoowigal CCA Zone 3 State Conservation Area (DPI NSW, 2002; DECC, 2005b). • Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact Granite Homoranthus. Fire • Develop and implement an appropriate fire management strategy to protect Granite Homoranthus from frequent fires (DECC, 2005a). • Identify appropriate intensity and interval of fire to promote seed germination and/or vegetation regeneration. • Provide maps of known occurrences to local and state Rural Fire Services and seek inclusion of mitigative measures in bush fire risk management plans, risk register and/or operation maps. Conservation Information • Raise awareness of Granite Homoranthus within the local community and support local Landcare groups to help conserve the species (DECC, 2005a). Enable Recovery of Additional Sites and/or Populations • Undertake appropriate seed collection and storage. • Investigate options for linking, enhancing or establishing additional populations. • Implement national translocation protocols (Vallee et al., 2004) if establishing additional populations is considered necessary and feasible. Local Priority Actions The following local priority recovery and threat abatement actions can be done to support the recovery of Granite Homoranthus. Habitat Loss, Disturbance and Modification • Control access routes to suitably constrain public access to known sites on public land. • Minimise adverse impacts from land use at known sites. Homoranthus prolixus Conservation Advice - Page 2 of 3 This conservation advice was approved by the Minister / Delegate of the Minister on 3 July 2008 Trampling, Browsing or Grazing • Prevent grazing and trampling pressure at known sites through exclusion fencing or other barriers. • Control introduced pests such as pigs and goats (DECC, 2005a) to manage threats at known sites in reserve areas. Invasive Weeds • Identify and remove weeds in the local area, which could become a threat to Granite Homoranthus, using appropriate methods. • Manage sites to prevent introduction of invasive weeds, which could become a threat to Granite Homoranthus, using appropriate methods. This list does not necessarily encompass all actions that may be of benefit to Homoranthus prolixus, but highlights those that are considered to be of highest priority at the time of preparing the conservation advice. Existing Plans/Management Prescriptions that are Relevant to the Species • NSW Priority Action Statement for Homoranthus prolixus (DECC, 2005b), • The Basin Nature Reserve – Plan of Management (NSW NPWS, 2004), • Threat Abatement Plan for Predation, Habitat Degradation, Competition and Disease Transmission by Feral Pigs (DEH, 2005), and • Threat Abatement Plan for Competition and Land Degradation by Feral Goats (EA, 1999).

Nuytsia 20: 309–318 (2010). Verticordia mitchelliana subsp. implexior A.S.George & M.D.Barrett and Verticordia setacea A.S.George are described and discussed. Verticordia setacea belongs with V. gracilis A.S.George in section Platandra, previously a monotypic section. Introduction The genus Verticordia DC. (Myrtaceae: tribe Chamelaucieae) is a charismatic group of shrubs found mainly in south-western Australia, with several species in adjacent arid regions and three in tropical Australia (George 1991; George & Pieroni 2002). Verticordia is currently defined solely on the possession of divided calyx lobes, but the limits between Verticordia and the related genera Homoranthus A.Cunn. ex Schauer, Chamelaucium Desf. and Darwinia Rudge are difficult to define conclusively, and other characteristics such as anther morphology suggest conflicting relationships (Bentham 1867; Craven & Jones 1991; George 1991). A recent analysis using a single chloroplast gene, with limited sampling of Verticordia taxa (Ma et al. 2002), suggests that Verticordia may be polyphyletic.

  • Variation in Seed Production and Germination in 22 Rare and Threatened Western Australian Verticordia (Myrtaceae)
    Journal of the Royal Society of Western Australia, 84:103-110, 2001 Variation in seed production and germination in 22 rare and threatened Western Australian Verticordia (Myrtaceae) A Cochrane1, K Brown2, S Cunneen3 & A Kelly4 1Threatened Flora Seed Centre, Department of Conservation and Land Management, Locked Bag 104, Bentley Delivery Centre, Perth WA 6983 2Environmental Weeds Action Network, 108 Adelaide Terrace, East Perth WA 6000 3CSIRO Centre for Mediterranean Agricultural Research, Floreat WA 6014 424 Carnarvon St, East Victoria Park WA 6100 email: [email protected] Manuscript received August 2000, accepted March 2001 Abstract This study investigates the reproductive potential of 22 rare and threatened Western Australian taxa in the genus Verticordia (Myrtaceae) over a 5-year period. Considerable inter- and intra-specific variation in both seed production and germinability was demonstrated for the majority of taxa. The seed to flower ratio, or “seed set”, ranged from 0% to 68% with an overall mean of 21% in 82 accessions representing seed from 48 populations of the 22 taxa. Percentage germination ranged from 7% to 100% with an average of 49% for 68 accessions. The precariously low annual reproductive capacity of some of the more restricted and critically endangered taxa threatens their survival and unexpected disturbance events may result in population decline or even localised extinction. Mitigation measures such as the reintroduction of plant material into new sites and the enhancement of existing populations through additional plantings may be warranted for many of Western Australia’s rare and threatened Verticordia. Keywords: Verticordia, seed production, germination Introduction prominently displayed feathery flowers are borne singly but appear as heads or spikes and are generally brightly Verticordia (family Myrtaceae, sub-family coloured, ranging from yellow to red to purple.

  • Conservation Advice: Homoranthus Bebo L.M. Copel (Myrtaceae)
    Homoranthus bebo L.M. Copel (Myrtaceae) Distribution: Endemic to NSW Current EPBC Act Status: Under consideration for listing as Critically Endangered Current NSW TSC Act Status: Not Listed Proposed change for alignment: List as Critically Endangered on EPBC Act Conservation Advice: Homoranthus bebo Summary of Conservation Assessment Homoranthus bebo was found to be eligible for listing as Critically Endangered under Criterion B1ab(iii, v) + 2ab(iii, v). The main reasons for this species being eligible are i) that it has a highly restricted geographic distribution with both an extent of occurrence (EOO), estimated by calculating the area within the smallest possible polygon containing all known records as per IUCN Guidelines (2016), and an area of occupancy (AOO), estimated using 2 x 2 km grids as per IUCN Guidelines (2016), of 4 km2; ii) the species is known from a single location in Dthinna Dthinnawan Nature Reserve in the far North of NSW; iii) there is a projected continuing decline inferred in area, extent and/or quality of habitat and number of mature individuals as the species appears extremely sensitive to fire and observations suggest very slow rates of recruitment and recolonization of burnt patches, hampering the species ability to recover following disturbance events. The size and extent of the population is such that the entire species could be lost during a single fire event of moderate severity if it is assumed that all adult plants are killed by fire and there is no seedling recovery post- fire (as has been observed in response to a recent fire). Description and Taxonomy Homoranthus bebo was first described by L.

  • Notes on Myrtace (Continued)
    MR. 0. DENTIIhM 05 M\PPRTILCEIE. 129 HOMORANTHUS,A. Cixnn., is a single species which has scarcely even the claims of Actinodium to be excluded from Darwinia, dif- fering from the latter genus only in the subulate calyx-lobes. Its retention may, however, be justified as facilitating the distinction between Darwinia and Perticordia. VERTICORDTA,DC., contains at present 37 species, showing considerable diversity in the structure of the anthers as well as in the ovule?, and connected together by the single character of the dissected or plumose calyx-lobesj but this character gives so peculiar an aspect that it is justly allowed to supersede all others, and the genus is universally acknowledged in its integrity. The only separation proposed was Lindley's CltrysorrhoC, in the original species of. which a very singular form of anther was observed to be connected with the bright-yellow flower. Subsequent researches, however, have shown in other species a gradual passage from these singular-shaped anthers to one of the two normal types of the genus, and that they do not correspond at all with the colour of the flower; and Chrysorrhol was very soon given up even as a section. The division of Verticordia into two artificial sections, by the same characters which mpply the more natural separa- tion of Darwinia from Chamcelaucium, has been already alluded to; and further details on the arrangement of the species are now superseded by the ' Flora Aushraliensis.' PILEANTHUS,Labill., is an old genus of two or three species, characterized, again, chiefly by the calyx, in which accessory lobes are produced from the sinus precisely resembling the primary ones, the whole ten being broad, petal-like, and spreading, giving the calyx a shuttlecock-aspect, accompanied alao by a conversion of the staminodia into stamens, thus doubling the number of perfect stamens as well as of calyx-lobes.

  • Customer Service Advice from Foxtel
    CUSTOMER SERVICE ADVICE FROM FOXTEL Extreme Weather events impact service in the Northern Tablelands District and parts of the Northern Rivers, Mid North Coast, North West Slopes and Plains Districts of New South Wales and part of the Darling Downs and Granite Belt District of Queensland. As previously notified by Foxtel on Friday 20 January 2017, Foxtel’s normal operations in the Northern Tablelands District and parts of the Northern Rivers, Mid North Coast, North West Slopes and Plains Districts of New South Wales and part of the Darling Downs and Granite Belt District of Queensland were affected by a series of extreme weather events on or about Thursday 12 January 2017 through to Sunday 15 January 2017. The network used to deliver Foxtel’s services in these areas has experienced high levels of damage that resulted in delays to installation and repair activities on a significant number of Foxtel services. Due to the extent of damage to the network used to deliver Foxtel’s telecommunications services, the impact in the effected region has been greater than initially estimated, and as a consequence of the continued weather effects, the expected recovery date has now been extended to 2 April 2017. Foxtel has identified that the effect of these circumstances applies to approximately 465 services. This number may increase as Foxtel assesses the full effect of the severe weather conditions. Based on current information, the resumption date of normal service operations is expected to be 2 April 2017. This date is indicative only, and Foxtel customers should anticipate that some further delays may occur.

  • Darwinia Hortiorum (Myrtaceae: Chamelaucieae), a New Species from the Darling Range, Western Australia
    K.R.Nuytsia Thiele, 20: 277–281 Darwinia (2010) hortiorum (Myrtaceae: Chamelaucieae), a new species 277 Darwinia hortiorum (Myrtaceae: Chamelaucieae), a new species from the Darling Range, Western Australia Kevin R. Thiele Western Australian Herbarium, Department of Environment and Conservation, Locked Bag 104, Bentley Delivery Centre, Western Australia 6983 Email: [email protected] Abstract Thiele, K.R. Darwinia hortiorum (Myrtaceae: Chamelaucieae), a new species from the Darling Range, Western Australia. Nuytsia 20: 277–281 (2010). The distinctive, new, rare species Darwinia hortiorum is described, illustrated and discussed. Uniquely in the genus it has strongly curved- zygomorphic flowers with the sigmoid styles arranged so that they group towards the centre of the head-like inflorescences. Introduction Darwinia Rudge comprises c. 90 species, mostly from the south-west of Western Australia with c. 15 species in New South Wales, Victoria and South Australia. Phylogenetic analyses (M. Barrett, unpublished) have shown that the genus is polyphyletic, with distinct eastern and western Australian clades. Along with the related genera Actinodium Schauer, Chamelaucium Desf., Homoranthus A.Cunn. ex Schauer and Pileanthus Labill., the Darwinia clades are nested in a paraphyletic Verticordia DC. Many undescribed species of Darwinia are known in Western Australia, and these are being progressively described (Rye 1983; Marchant & Keighery 1980; Marchant 1984; Keighery & Marchant 2002; Keighery 2009). A significant number of taxa in the genus are narrowly endemic or rare and are of high conservation significance. Although taxonomic reassignment of the Western Australian species of Darwinia may be required in the future, resolving the status of these undescribed species and describing them under their current genus helps provide information for conservation assessments and survey.

Terms such as lignotuber, xylopodium and sobole, all referring to belowground bud-bearing structures, are used inconsistently in the literature. Key words: bud bank, fire-prone ecosystems, Because soil efficiently insulates meristems from the heat of fire, concealing buds below ground lignotuber, resprouting, rhizome, xylopodium. provides fitness benefits in fire-prone ecosystems. Thus, in these ecosystems, there is a remarkable diversity of bud-bearing structures.

  • Listing Advice Page 1 of 4
    The Minister deleted this species from the vulnerable category, effective from 14 December 2013 Advice to the Minister for the Environment from the Threatened Species Scientific Committee (the Committee) on Amendment to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Reason for Conservation Assessment by the Committee This advice follows assessment of new information provided on: Bothriochloa biloba (lobed blue-grass) 2. Summary of Species Details Taxonomy Conventionally accepted as Bothriochloa biloba S.T.Blake State Listing Status Previously listed as vulnerable in both New South Wales and Queensland, but has been de-listed in both states. Description An erect or decumbent grass growing to 1 m high (Harden, 1993). It can easily be distinguished from other Bothriochloa species by its lobed upper lemma (bract enclosing the flower) which remains attached to the base of the awn when the awn is pulled out of the spikelet (Quinn et al., 1995). Flowering occurs from November to June (Creamer, 1999; Sharp and Simon, 2001). This species occurs within the EPBC listed ecological community ‘Natural grasslands on basalt and fine-textured alluvial plains of northern New South Wales and southern Queensland’. Distribution Restricted to northern New South Wales and southern Queensland. It extends from the Darling Downs district in Queensland, south along the western slopes of the Great Dividing Range to near North Star, Warialda, Bingara and Merriwa in New South Wales (NSW SC, 2003; Quinn et al., 1995). Relevant A recent study conducted on this species (Yu et al., 2003) Biology/Ecology indicates that it has a complex reproductive system involving sexual and asexual (apomictic) mechanisms.

Rye Western Australian Herbarium, Department of Parks and Wildlife, Locked Bag 104, Bentley Delivery Centre, Western Australia 6983 Abstract Rye, B.L. An expanded circumscription and new infrageneric classification of Rinzia (Myrtaceae: Chamelaucieae). Nuytsia 28: 39–93 (2017). The circumscription of Rinzia Schauer (Myrtaceae tribe Chamelaucieae DC.) is enlarged to encompass species with varied stamen arrangement, filament width and seed morphology. This revision of Rinzia s. lat. is based on both morphological and molecular evidence, and establishes five sections within the genus,Discolora Rye, Mesostemon Rye, Polyandra Rye, Semasperma Rye and the typical section. All sections occur in Western Australia, with three of them endemic to the south-west, while sect. Polyandra also occurs in central Australia and sect. Semasperma also occurs in south-eastern Australia. Three new combinations are made for species previously included within Baeckea L., and the new name R. orientalis Rye is published for B. crassifolia Lindl. Baeckea crassifolia var. icosandra F.Muell. ex Benth. is raised to species rank as R. icosandra (F.Muell. ex Benth.) Rye. The other new combinations are R. ericaea (F.Muell. ex Benth.) Rye and R. polystemonea (F.Muell.) Rye. Four new Western Australian species are described as R. fimbriolata Rye & Trudgen, R. medifila Rye, R. torquata Rye & Trudgen and R. triplex Rye & Trudgen, and a new subspecies from Kangaroo Island, South Australia, as R.

B. poiciloptilus is a large, stocky, thick-necked heron-like bird with camouflage-like plumage growing up to 66-76 cm with a wingspan of 1050-1180 cm and feeds on freshwater crustacean, fish, insects, snakes, leaves and fruit. N. oxleyana is light brown to olive coloured freshwater fish with mottling and three to four patchy, dark brown bars extending from head to tail and a whitish belly growing up to 35-60 mm. This is a mobile species that is often observed individually or in pairs and sometimes in small groups but does not form schools and feed on aquatic insects and their larvae (Allen, 1989; McDowall, 1996). E. leuraensis is an insectivorous, medium-sized lizard growing to approximately 20 cm in length. This species has a relatively dark brown/black body when compared to other Eulamprus spp. Also has narrow yellow/bronze to white stripes along its length to beginning of the tail and continuing along the tail as a series of spots (LeBreton, 1996; Cogger, 2000).

  • New South Wales Summer 2018-19 Particle Episode Newsletter
    Particle episodes in Summer 2018–19 PM10 (particles less than or equal to 10 microns in diameter) – The network recorded 34 days with daily PM10 concentrations above the national benchmark of 50 micrograms per cubic metre (µg/m3), which is higher than the previous four summers. This was attributed to drought conditions in New South Wales, which led to a significant number of widespread or localised dust events. PM2.5 (particles less than or equal to 2.5 microns in diameter) – Two days were above the daily 3 PM2.5 benchmark of 25 µg/m , one due to widespread dust and one due to a local grass fire. Comparison to previous summers – For regional NSW, the number of days above the PM10 benchmark in summer 2018–19 was not unprecedented, with five previous summers since 2002 recording a comparable number of days. These previous seasons were due to a combination of dust and bushfire events, while the 2018-19 summer was affected primarily by dust events. Climate conditions – This summer was the warmest on record for New South Wales. A significant drought-affected 99.9% of the State, with inland regions most severely impacted. Additional information1 – The NSW air quality monitoring network recorded generally good air quality between 1 December 2018 to 28 February 2019. Across the network, the air quality index (AQI) due to particles was fair or better for 71% of days in the South West Slopes, 91% in the Central Tablelands and North West Slopes, 92% in the Illawarra, 93% in the Upper Hunter, 97% in Sydney, 99% in the Lower Hunter and 100% in the Central Coast.
