Approved Conservation Advice for Baloskion Longipes This conservation advice was approved by the Minister / Delegate of the Minister on: 26/3/2008 A statement for the purposes of approved conservation advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Baloskion longipes This Conservation Advice has been developed based on the best available information at the time this conservation advice was approved. Description Baloskion longipes, Family Restionaceae, previously listed as Restio longipes, is a perennial, grass-like erect sedge with culms (flowering stems) to 150 cm long arising from a compact rhizome (underground stem) (Meney & Pate, 1999; DECC, 2005). This dioecious taxon (male and female flowers on different plants) flowers in summer with seed maturation taking a further 6–8 months (Meney & Pate, 1999). The species is known to resprout after fire (Meney & Pate, 1999). Conservation Status Baloskion longipes 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, Restio longipes was listed as vulnerable under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). The species is also listed as vulnerable under the Threatened Species Conservation Act 1995 (NSW). Distribution and Habitat Baloskion longipes is known from the Kanangra–Boyd area in the Southern Tablelands (NSW) (DECC, 2005). Populations have been recorded in the Blue Mountains National Park (NP), Kanangra–Boyd NP, Penrose State Forest (in Hanging Rock Swamp), Morton NP (The Vines), the Clyde Mountain area and Ballalaba (south of Braidwood) (DECC, 2005). This species occurs within the Hawkesbury–Nepean, Hunter–Central Rivers, Lachlan and Southern Rivers (NSW) Natural Resource Management Regions (DECC, 2005). All known populations of the species are small (DECC, 2005). The species grows in seasonally inundated peat, sandy wetland swamps (Meney & Pate, 1999) or depressions in sandy alluvium (Harden, 1993), sometimes growing with Sphagnum Moss (DECC, 2005). It also occurs in swales within tall forest and in Eucalyptus aggregata Woodland (DECC, 2005). The distribution of this species overlaps with the ‘Temperate Highland Peat Swamps on Sandstone’ EPBC Act-listed threatened ecological community. Threats The main identified threats to B. longipes include road works and weed spraying (particularly in the Clyde Mountain and Ballalaba populations due to their close proximity to roads); and feral pigs (Sus scrofa) rooting for food, directly damaging the species and surrounding habitat (DECC, 2005). The main potential threats to B. longipes are changes to hydrology; animal predation or competition; fragmentation and loss of habitat (ANRA, 2007). Research Priorities Research priorities that would inform future regional and local priority actions include: • Design and implementation of a monitoring program, and Baloskion longipes Conservation Advice - Page 1 of 4 This conservation advice was approved by the Minister / Delegate of the Minister on: 26/3/2008 • Undertake survey work in suitable habitat and potential habitat to locate any additional populations/occurrences/remnants. Regional Priority Actions The following regional priority recovery and threat abatement actions can be done to support the recovery of Baloskion longipes. Habitat Loss, Disturbance and Modification • Identify populations of high conservation priority. • Manage threats to areas of vegetation that contain populations/occurrences/remnants of Baloskion longipes. • Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact on Baloskian longipes. • Ensure road widening and maintenance activities (or other infrastructure or development activities as appropriate) in areas where B. longipes occurs do not adversely impact on known populations (particularly for the Clyde Mountain and Ballalaba populations). • Manage any changes to hydrology that may result in changes to the water table levels, increased run-off, sedimentation or pollution. • Investigate formal conservation arrangements such as the use of covenants, conservation agreements or inclusion in reserve tenure. Animal Predation or Competition • Develop and implement a management plan for the control or eradication of feral pigs in the local region. Fire • Develop and implement a suitable fire management strategy for Baloskion longipes. • Identify appropriate intensity and interval of fire to promote seed germination. • 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 B. longipes within the local community. • Erect signs to alert management staff to the presence of this species (DECC, 2005). Enable Recovery of Additional Sites and/or Populations • 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. • Undertake appropriate seed collection and storage. • Undertake seed germination trials to determine the requirements for successful establishment. Local Priority Actions The following local priority recovery and threat abatement actions can be done to support the recovery of Baloskion longipes. 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. • Control access routes to suitably constrain public access to known sites on public land. • Suitably control and manage access on private land. • Minimise adverse impacts from land use at known sites. Baloskion longipes Conservation Advice - Page 2 of 4 This conservation advice was approved by the Minister / Delegate of the Minister on: 26/3/2008 • Manage any disruptions to water flows. • Protect populations through the development of conservation agreements and/or covenants. • Protect Ballalaba and Clyde Mountain populations from disturbance with bollards and signage (DECC, 2005). Invasive Weeds • Identify and remove weeds in the local area, which could become a threat to B. longipes, using appropriate methods (herbicide spraying near B. longipes should be avoided). • Manage sites to prevent introduction of invasive weeds, which could become a threat to B. longipes, using appropriate methods. Trampling, Browsing or Grazing • Prevent grazing pressure at known sites through exclusion fencing or other barriers. Animal Predation or Competition • Manage threats at known sites in reserve areas and on private property to control introduced pests such as feral pigs. • Continue baiting to control population numbers of introduced pests, particularly feral pigs. Fire • Implement an appropriate fire management regime for local populations. • Inform the Rural Fire Service about populations adjoining roads and tracks to ensure that plants are considered when fire suppression activities are planned (DECC, 2005). This list does not necessarily encompass all actions that may be of benefit to B. longipes, but highlights those that are considered to be of highest priority at the time of preparing the conservation advice.

  • Vicariance, Climate Change, Anatomy and Phylogeny of Restionaceae
    Botanical Journal of the Linnean Society (2000), 134: 159–177. With 12 figures doi:10.1006/bojl.2000.0368, available online at http://www.idealibrary.com on Under the microscope: plant anatomy and systematics. Edited by P. J. Rudall and P. Gasson Vicariance, climate change, anatomy and phylogeny of Restionaceae H. P. LINDER FLS Bolus Herbarium, University of Cape Town, Rondebosch 7701, South Africa Cutler suggested almost 30 years ago that there was convergent evolution between African and Australian Restionaceae in the distinctive culm anatomical features of Restionaceae. This was based on his interpretation of the homologies of the anatomical features, and these are here tested against a ‘supertree’ phylogeny, based on three separate phylogenies. The first is based on morphology and includes all genera; the other two are based on molecular sequences from the chloroplast genome; one covers the African genera, and the other the Australian genera. This analysis corroborates Cutler’s interpretation of convergent evolution between African and Australian Restionaceae. However, it indicates that for the Australian genera, the evolutionary pathway of the culm anatomy is much more complex than originally thought. In the most likely scenario, the ancestral Restionaceae have protective cells derived from the chlorenchyma. These persist in African Restionaceae, but are soon lost in Australian Restionaceae. Pillar cells and sclerenchyma ribs evolve early in the diversification of Australian Restionaceae, but are secondarily lost numerous times. In some of the reduction cases, the result is a very simple culm anatomy, which Cutler had interpreted as a primitively simple culm type, while in other cases it appears as if the functions of the ribs and pillars may have been taken over by a new structure, protective cells developed from epidermal, rather than chlorenchyma, cells.

  • New Combinations Arising from a New Classification of Non-African
    21 New combinations arising from a new classification of non-African Restionaceae Barbara G. Briggs and L.A.S. Johnson† Abstract Briggs, Barbara G. and Johnson, L.A.S. (Royal Botanic Gardens, Mrs Macquaries Road, Sydney, NSW 2000, Australia) 1998. New combinations arising from a new classification of non-African Restionaceae. Telopea 8(1): 21–33. New combinations are made in accord with a new, broadly based classification of extra- African Restionaceae. These involve 39 Australian species, of which two extend to New Guinea and the Aru Islands, and one species in each of south-east Asia, New Zealand and Chile. The name Baloskion Raf. is adopted for eight eastern Australian species excluded from Restio Rottb. and Desmocladus Nees is adopted for a group of Western Australian species mostly transferred from Loxocarya R. Br. The previously monotypic genera Meeboldina Suesseng. and Sporadanthus F. Muell. are enlarged. Most other changes involve newly described genera. Four combinations replace illegitimate epithets, two new combinations are made at subspecific rank, and lectotypes are selected for 18 taxa. Introduction A new classification of the genera and species of Australian Restionaceae has been developed through study of exomorphology, anatomy, pollen, seed ornamentation, and flavonoids, with associated DNA sequence studies in progress. The classification is outlined by Briggs and Johnson (1999) and Linder, Briggs and Johnson (1998). It has led to the recognition of 16 new genera (Briggs & Johnson 1998) and has shown that the species hitherto included in some of the genera are unnatural assemblages of taxa. The largest group of inappropriately placed species have until now been referred to Restio Rottb.

A fire response trait that allows plants to cope with frequent fire by either reseeding or resprouting could differentially affect rates of species diversification. However, little is known about the generality of the effects of differing fire response on species evolution. We study this question in the Restionaceae, a family that radiated in Southern Africa and Australia. These radiations occurred independently and represent evolutionary replicates. We apply Bayesian approaches to estimate trait-specific diversification rates and patterns of climatic niche evolution. We also compare the climatic heterogeneity of South Africa and Australia. Reseeders diversify faster than resprouters in South Africa, but not in Australia.

  • Nuclear Genes, Matk and the Phylogeny of the Poales
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2018 Nuclear genes, matK and the phylogeny of the Poales Hochbach, Anne ; Linder, H Peter ; Röser, Martin Abstract: Phylogenetic relationships within the monocot order Poales have been well studied, but sev- eral unrelated questions remain. These include the relationships among the basal families in the order, family delimitations within the restiid clade, and the search for nuclear single-copy gene loci to test the relationships based on chloroplast loci. To this end two nuclear loci (PhyB, Topo6) were explored both at the ordinal level, and within the Bromeliaceae and the restiid clade. First, a plastid reference tree was inferred based on matK, using 140 taxa covering all APG IV families of Poales, and analyzed using parsimony, maximum likelihood and Bayesian methods. The trees inferred from matK closely approach the published phylogeny based on whole-plastome sequencing. Of the two nuclear loci, Topo6 supported a congruent, but much less resolved phylogeny. By contrast, PhyB indicated different phylo- genetic relationships, with, inter alia, Mayacaceae and Typhaceae sister to Poaceae, and Flagellariaceae in a basally branching position within the Poales. Within the restiid clade the differences between the three markers appear less serious. The Anarthria clade is first diverging in all analyses, followed by Restionoideae, Sporadanthoideae, Centrolepidoideae and Leptocarpoideae in the matK and Topo6 data, but in the PhyB data Centrolepidoideae diverges next, followed by a paraphyletic Restionoideae with a clade consisting of the monophyletic Sporadanthoideae and Leptocarpoideae nested within them. The Bromeliaceae phylogeny obtained from Topo6 is insufficiently sampled to make reliable statements, but indicates a good starting point for further investigations.

  • New Genera and Species of Australian Restionaceae (Poales)
    345 New genera and species of Australian Restionaceae (Poales) Barbara G. Briggs and L.A.S. Johnson† Abstract Briggs, Barbara G. and Johnson, L.A.S. (Royal Botanic Gardens, Mrs Macquaries Road, Sydney, NSW 2000, Australia) 1998. New genera and species of Australian Restionaceae (Poales). Telopea 7(4): 345–373. Sixteen new genera and five new species of Australian Restionaceae are described and combinations made for a further eleven species. Newly described genera are Catacolea, Kulinia, Guringalia, Acion, Saropsis, Chordifex, Eurychorda, Platychorda, Tremulina, Melanostachya, Taraxis, Tyrbastes, Cytogonidium, Stenotalis, Dapsilanthus, Apodasmia. Newly described type species are: Catacolea enodis, Kulinia eludens, Chordifex stenandrus, Taraxis grossa, Tyrbastes glaucescens. New combinations are made for the type species of the remaining genera: Guringalia dimorpha, Acion monocephalum, Saropsis fastigiata, Eurychorda complanata, Platychorda applanata, Tremulina tremula, Melanostachya ustulata, Cytogonidium leptocarpoides, Stenotalis ramosissima, Dapsilanthus elatior, Apodasmia brownii. Lectotypes are selected for several species. Brief comment is included on culm anatomy, flavonoids, seed ornamentation and DNA findings, in addition to exomorphological features. Keys are provided to distinguish the new genera from other members of the Desmocladus, Loxocarya and Leptocarpus groups. All the new genera occur in Australia but Apodasmia also includes species in New Zealand and Chile while Dapsilanthus is represented also in New Guinea, Aru Islands and Southeast Asia. Introduction The last comprehensive systematic account of Australian Restionaceae was by Bentham (1878), building especially on the notable work of Brown (1810) and Mueller (1872–4). Subsequently 12 relevant new genera have been described, but two of these, Desmocladus Nees and Baloskion Raf., were never adopted by botanists in Australia and one, Sporadanthus F.

  • Restionaceae (Poales) in the Footsteps of Robert Brown
    499 Restionaceae (Poales) in the footsteps of Robert Brown Barbara G. Briggs Abstract Barbara G. Briggs (National Herbarium of New South Wales, Mrs Macquaries Road, Sydney 2000, Australia; [email protected].) 2004. Restionaceae (Poales) in the footsteps of Robert Brown. Telopea 10(2): 499–503. Brown visited major centres of restiad diversity in Africa at the Cape of Good Hope and in Western Australia at King Georges Sound and Lucky Bay; other taxa were collected in northern and eastern Australia, including Tasmania. He described five genera and 36 species now included in Restionaceae, and four genera and 35 species since excluded from that family. His observation, enlightened by fieldwork, was remarkable and some species he named are now recognised again after decades in confusion or synonymy. Mostly he correctly matched dioecious males and females, but for one species these were placed in different genera. Restionaceae has been much cut down in size since Brown’s time. In the Prodromus, Restiaceae included what are now Anarthriaceae, Centrolepidaceae, Eriocaulaceae and Xyridaceae, as well as Lyginiaceae if this and Hopkinsiaceae are recognised as separate from Anarthriaceae sens. strict. Currently 145 Australian Restionaceae species are recognised, in 31 genera. The 24 species that Brown included in Restio (22 of them then newly described) are now distributed among 11 genera, the majority in Chordifex, Baloskion and Hypolaena, while Restio is restricted to African and Madagascan species. Anatomy, palynology and especially DNA sequencing have clarified relationships within Restionaceae and between families of Poales. Molecular data indicate that Centrolepidaceae forms the sister-group to Restionaceae, unless it is embedded in the latter.

Griffith1, C. Bale1, P. Adam2 and R. Wilson3 1Centre for Ecology, Evolution and Systematics, University of New England, Armidale, NSW, AUSTRALIA 2351, 2School of Biological, Earth and Environmental Sciences, University of New South Wales, Sydney, NSW, AUSTRALIA 2052, 315/137 Jabanungga Avenue, Ngunnawal, ACT, AUSTRALIA 2913. Abstract: Wallum is the regionally distinct vegetation on coastal dunefields, beach ridge plains and sandy backbarrier flats in subtropical northern NSW and southern Queensland (22°S to 33°S). This study examined floristic patterns in the wallum and allied vegetation along 400 km of coastline in north-eastern NSW. Floristic and environmental data were compiled for 494 quadrats allocated on the basis of air photo pattern and latitude. A phytosociological classification displayed strong congruence with an initial classification based upon photo pattern, especially for single stratum vegetation, thereby suggesting that API (air photo interpretation) is a valuable technique for the recognition of floristic assemblages. The utility of API for depicting the spatial distribution of tallest stratum species in multi-stratum vegetation was also confirmed. Nonetheless, photo signatures of the tallest stratum are less satisfactory as surrogates for identifying noda for the full complement of species in multi-stratum vegetation. Ordination supported the numerical classification, and reinforced the value of API for capturing meaningful biological and environmental data. Plant – environment relationships were examined for a range of variables. The consistent trend to emerge was a comparatively strong correlation between floristic composition and topographic position, and in some instances also between floristic composition and geology.
