The weed assessment was required to identify the extent of environmental and noxious weed species, identify measures for control and outline mitigation measures to be implemented during each phase of the project. This investigation will also assist VicRoads to ensure that the project is undertaken in a manner consistent with the principles of Ecologically Sustainable Development, and meets relevant Commonwealth and State environmental legislation requirements. Study Area The study area consists primarily of road reserve and private properties on either side of the Western Highway, between Beaufort and Ararat, situated approximately 170 kilometres west of Melbourne, Victoria.

  • Flerårig Steppegræs (Ehrharta Calycina)
    Flerårig steppegræs (Ehrharta calycina) Beskrivelse Videnskabeligt navn: Ehrharta calycina Sm. Synonymer: De hyppigst anvendte synonymer er Aira capensis L.f. Ehrharta ascendens Schrad. Ehrharta auriculata Steud. Ehrharta geniculate (Thunb.) Thunb. Melica festucoides Licht. Ex Trin. Trochera calycina Sm. P. Beauv. Kaldenavn: flerårig steppegræs Beskrivelse Flerårig steppegræs er en tuedannende 30-75 cm høj, som det danske navn siger, flerårig græs med grønne til grønviolette 2-7 mm brede blade1,2. Hver tue har typisk mange skud. Blomsterstanden er en åben 10-15 cm lang top med mange siddende eller kortstilkede småaks, der er 5-8 mm lange. I hvert småaks er der tre blomster, hvoraf kun den øverste er fertil. Yderavnerne er af længde som småakset og violette. Planten har en meget lang blomstringsperiode, der varer op til et halvt år2. Flerårig steppegræs er vindbestøvet og producerer mange frø, der naturligt primært spredes via vinden, men planten har også dyrespredning og spredes med vand. Frøene ligger sædvanligvis på jordoverfladen, hvor de spirer efter regn. Arten har dog også en frøbank, der kan opnå meget høje tætheder (75.000 frø pr. m2)2,3. Efter brand spirer sædvanligvis kun omkring halvdelen af frøbanken, således er der en reserve til senere måske mere gunstige tidpunkter for spiring og etablering3. Planten danner sjældent udløbere1. Vegetativ spredning ses hyppigst, hvor arten vokser i fugtige habitater2. Ved stængelbasis har planten hvileknopper, der skyder efter forstyrrelser2. Dette er især væsentligt i områder, hvor der forekommer brand; da frøene ligger på jordoverfladen er de meget udsatte ved brand hvorimod tuerne bedre tåler branden og spiring fra hvileknopperne fremmes ved brand3.

  • Unassisted Invasions: Understanding and Responding to Australia's High
    CSIRO PUBLISHING Australian Journal of Botany, 2017, 65, 678–690 Turner Review No. 21 https://doi.org/10.1071/BT17152 Unassisted invasions: understanding and responding to Australia’s high-impact environmental grass weeds Rieks D. van Klinken A,C and Margaret H. Friedel B ACSIRO, EcoSciences Precinct, PO Box 2583, Brisbane, Qld 4001, Australia. BCSIRO, PO Box 2114, Alice Springs, NT 0871, Australia. CCorresponding author. Email: [email protected] Abstract. Alien grass species have been intentionally introduced into Australia since European settlement over 200 years ago, with many subsequently becoming weeds of natural environments. We have identified the subset of these weeds that have invaded and become dominant in environmentally important areas in the absence of modern anthropogenic disturbance, calling them ‘high-impact species’. We also examined why these high-impact species were successful, and what that might mean for management. Seventeen high-impact species were identified through literature review and expert advice; all had arrived by 1945, and all except one were imported intentionally, 16 of the 17 were perennial and four of the 17 were aquatic. They had become dominant in diverse habitats and climates, although some environments still remain largely uninvaded despite apparently ample opportunities. Why these species succeeded remains largely untested, but evidence suggests a combination of ecological novelty (both intended at time of introduction and unanticipated), propagule pressure (through high reproductive rate and dominance in nearby anthropogenically-disturbed habitats) and an ability to respond to, and even alter, natural disturbance regimes (especially fire and inundation). Serious knowledge gaps remain for these species, but indications are that resources could be better focused on understanding and managing this limited group of high-impact species.

  • Species Groups in the Genus Ehrharta (Poaceae) in Southern Africa
    Bothalia 17,1:51-65(1987) Species groups in the genus Ehrharta (Poaceae) in southern Africa G. E. GIBBS RUSSELL* AND R. P. ELLIS* Keywords: anatomy, Ehrharta, morphology, Poaceae, southern Africa, taxonomy ABSTRACT Ehrharta Thunb. is a genus of Gondwanaland distribution with its centre of diversity in the winter rainfall Fynbos Biome of southern Africa. In recent subfamily treatments Ehrharta has proved difficult to place satisfactorily, and during the past five years it has been moved between Bambusoideae and Arundinoideae. However, most previous systematic studies using cryptic characters have covered only four taxa out of about 35. The present study includes all African taxa, and demarcates seven species groups on the basis of both spikelet morphology and leaf blade anatomy. Parallelism and/or convergence in vegetative macromorphology within and between the species groups is widespread, and is similar, in some cases, to adaptations found in other plant families in the Fynbos Biome. However, these macromorphological trends are not reflected in the leaf anatomy. Leaf anatomy is generally consistent with the spikelet morphology. Some anatomical differences between the species groups in Ehrharta appear to be as great as differences between taxa of much higher ranks elsewhere in the Poaceae. This wide range of variability may be related to an early divergence of Ehrharteae from other grasses, as suggested by the Gondwanaland distribution, and may explain the difficulty of placing this fascinating yet baffling genus in a subfamily. UITTREKSEL Ehrharta is ’n genus van Gondwanaland-verspreiding met sy middelpunt van verskeidenheid in die winterreenval-Fyn- bosbioom van suidelike Afrika. In onlangse subfamilie-behandelings is dit moeilik gevind om Ehrharta bevredigend te plaas, en gedurende die afgelope vyf jaar is dit oor en weer in Bambusoideae en Arundinoideae geplaas.
