To minimize these impacts, effective management of Received in revised form 2 August 2016 IAAPs is required according to national or international laws and regulations (e.g. the new EU regulation Accepted 2 August 2016 1143/2014). Prevention of the introduction of IAAPs is considered the most cost effective management Available online 23 September 2016 option. If/when prevention fails, early detection and rapid response increases the likelihood of eradica- tion of the IAAPs and can minimize on-going management costs. For effective weed control (eradication Keywords: and/or reduction), a variety of management techniques may be used. The goal or outcome of manage- Biological control ment interventions may vary depending on the site (i.e. a single waterbody, or a region with multiple Chemical control Eradication waterbodies) and the feasibility of achieving the goal with the tools or methods available. Broadly defined Early detection management goals fall into three different categories of, containment, reduction or nuisance control and EU regulation 1143/2014 eradication. Management of IAAP utilises a range of control methods, either alone or in combination, to Macrophyte achieve a successful outcome.

We analyzed the chemical composition (including: C, N, P, polyphenols, lignin, nonpolar extractables, and sugars) of M. spicatum and M. sibiricum and determined how the chemistry of the two species varied by plant part with growing environment (lake versus tank), irradiance (full sun versus 50% shading), and season (July through September). M. spicatum had higher concentrations of carbon, polyphenols and lignin (C: 47%; polyphenols: 5.5%; lignin: 18%) than M. sibiricum (C: 42%; polyphenols: 3.7%; lignin: 9%) while M. sibiricum had a higher concentration of ash under all conditions (12% versus 8% for M. spicatum). Apical meristems of both species had the highest concentration of carbon, polyphenols, and tellimagrandin II, followed by leaves and stems. Tellimagrandin II was present in apical meristems of both M. spicatum (24.6 mg gÀ1 dm) and M. sibiricum (11.1 mg gÀ1 dm).

Pest: Ludwigia grandiflora PRA area: The PRA area is the EPPO region (see map www.eppo.org). Assessors: A Draft PRA had been prepared by Mr Guillaume Fried, and the Expert Working Group was attended by the following experts: Mr Mustafa Selçuk Basaran, Plant Protection Central Research Institute, Turkey Mr Alain Dutartre, CEMAGREF, France Mr Guillaume Fried, LNPV Station de Montpellier, France Mr Jonathan Newman, Waterland Management Ltd, United Kingdom Mr Uwe Starfinger, Julius Kühn Institute, Germany Mr Johan van Valkenburg, Plant Protection Service, The Netherlands EPPO Secretariat: Ms Sarah Brunel Comments were received from Ms Iris Stiers, Vrije Universiteit Brussel, Belgium, and Mr Andreas Hussner, University of Duesseldorf, Germany. Peer review has been undertaken by Ms Schrader, Julius Kühn Institute, Germany. Date: Expert working group 06-2010, core member consultation 06-2011 STAGE 1: INITIATION Reason for doing PRA: L. grandiflora is widespread and invasive in the South and West of France but its distribution is still very limited in the North and East of France, as well as in Belgium, Germany, Ireland, Italy, the Netherlands, Spain and the UK where invasion is at an early stage.

    MONDAY SEPTEMBER 17 19 MANAGING INVASIVE PLANTS IN AUSTRALIA: A DECADE OF ACHIEVEMENT McFadyen R Cooperative Research Centre for Australian Weed Management, Indooroopilly, Brisbane Qld The first Cooperative Research Centre (CRC) for Weeds started in 1995 and the National Weeds Strategy was launched in 1997. The first national eradication campaign against an invasive plant started in 1994, and a ‘Permitted List’ system was adopted in 1998 for entry of new plant species into Australia, using a Weed Risk Assessment System. These were major advances in the management of invasive plants in Australia, and this paper discusses the critical policy issues and turning points along the way. It also considers where policy has failed and the critical challenges for the future. 20 21 CURRENT AND POTENTIAL GEOPHYTE WEEDS OF SOUTH-WESTERN AUSTRALIA Keighery GJ Department of Environment and Conservation, Science Division, Wanneroo, WA [email protected] South Western Australia is an internationally recognised biodiversity hotspot for flowering plants, containing over 6,000 species of which 75% are endemic. Altered land use since European settlement has lead to 1234 naturalised plants becoming established. These now pose a major threat to this biodiversity. Unlike SE Australia shrubs are a minor component of this weed flora, major weeds are grasses, annuals (Peas, Daisies and Brassicaceae) or geophytes. The 107 geophytic weeds present in Western Australia come from 18 families of plants, both Monocots and Dicots, although nearly half are cormous Iridaceae from southern Africa. Unlike many other areas of similar climates, Southern Western Australia is depauperate in geophytes, with about 200 species in our flora of c.

  • Hydrodictyon Reticulatum) in Lake Aniwhenua, New Zealand
    WELLS, CLAYTON: IMPACTS OF WATER NET 55 Ecological impacts of water net (Hydrodictyon reticulatum) in Lake Aniwhenua, New Zealand Rohan D. S. Wells and John S. Clayton National Institute of Water and Atmospheric Research, P.O. Box 11 115, Hamilton, New Zealand (E-mail: [email protected]) Abstract: The ecological impacts of Hydrodictyon reticulatum blooms (1989-94) were studied at Lake Aniwhenua (a constructed lake) in North Island, New Zealand by collating fish, invertebrate and macrophyte data collected towards the end of a four year bloom period and following its decline. Hydrodictyon reticulatum had some localised impacts on the biota of the lake. Some macrophyte beds were smothered to the extent that they collapsed and disappeared, and dense compacted accumulations of H. reticulatum caused localised anoxic conditions while it decayed. However, fish and some invertebrates in the lake benefited from the H. reticulatum blooms. High numbers of Ceriodaphnia sp. (maximum, 5.5 x 104 m-2) were recorded amongst H. reticulatum, and gastropods were exceptionally abundant, the most common being Potamopyrgus antipodarum (maximum, 1.8 x IOS m-2). Hydrodictyon reticulatum was consumed by three species of common gastropods in experimental trials, with Austropeplea tomentosa consuming up to 1.3 g dry weight H. reticulatum g-1,live weight of snail day-1. Gastropods comprised the major portion of the diet of Oncorhynchus mykiss in Lake Aniwhenua during and after the H. reticulatum bloom. A marked peak in sports fishing (with exceptional sizes and numbers of fish caught) coincided with the period of H. reticulatum blooms and the abundant invertebrate food source associated with the blooms.

Weaver, Jr., Ph.D., and Patti J. Anderson, Ph.D. For this period, 167 specimens were submitted to the Botany Section for identification, and 1,418 were received from other sections for identification/name verification for a total of 1,585. In addition, 57 specimens were added to the herbarium, and 48 specimens of invasive species were prepared for the Division of Forestry’s Forest Health Project. Some of the samples received for identification are discussed below: Helianthus simulans E. E. Wats. (an endemic North American genus of 49 species, occurring throughout the United States and adjacent Canada, as well as in Baja California). Compositae (Asteraceae). Muck sunflower. It is unfortunate that such an attractive plant has such an unattractive common name. Growing to more than 2 m tall, this sunflower makes a showy and impressive specimen in the garden. In its best forms, the lanceolate leaves are leathery and dark green, somewhat reminiscent of those of the oleander (Nerium oleander). The flower heads, with bright yellow rays and usually a reddish- purple disk, are borne in profusion in October and November and vary from 7-10 cm across. Although it grows at least twice as tall and the leaves are broader and not revolute (turned under along the margins), it is often confused with the very common Helianthus simulans Photograph courtesy of Sally Wasowski and swamp sunflower (H.
