Only two populations of this plant have been observed, both along disturbed roadsides on the West Coast of South Africa. The extent and invasive potential of this infestation in the country is still limited but the species is known to be an aggressive invader in other parts of the world. © 2011 SAAB.

  • Jervis Bay Territory Page 1 of 50 21-Jan-11 Species List for NRM Region (Blank), Jervis Bay Territory
    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.

  • California Department of Food and Agriculture
    DEPARTMENT OF FOOD AND AGRICULTURE PROPOSED CHANGES IN THE REGULATIONS Title 3, California Code of Regulations Section 4500 Noxious Weed Species INITIAL STATEMENT OF REASONS/ POLICY STATEMENT OVERVIEW Description of Public Problem, Administration Requirement, or Other Condition or Circumstance the Regulation is Intended to Address This regulation is intended to address the obligation of the Department of Food and Agriculture (Department) to protect the agricultural industry from the movement and spread of injurious noxious weeds into and within California. Specific Purpose and Factual Basis The specific purpose of section 4500 is to provide authority to the state to regulate the movement of the listed noxious weeds species into or within California. The factual basis for the determination by the Department that the amendment of this regulation is necessary is as follows: Invasive weeds have significant effects on the agricultural industry and environment. They can intensify drought impacts, increase fire hazard, decrease rangeland productivity, reduce water resources, raise nursery business costs, and diminish wildland diversity. Alien weeds spread to and invade approximately 700,000 hectares per year of U.S. wildlife habitat. One such pest weed, introduced in the early 19th century as an ornamental plant, is the European purple loosestrife. Spreading at a rate of 115,000 hectares per year, the weed population changes the basic structure of most of the invaded wetlands. Competitive stands of purple loosestrife have reduced the biomass of 44 native plant species and endangered wildlife such as the bog turtle that depends on these native plants. Loosestrife now occurs in 48 states and costs $45 million per year in control expenses and forage losses.

Ecological influences in the biogeography of the aus- tral sedges. MSc dissertation. University of Cape Town. Cape Town. February 2016. supervisors: A. Muthama Muasya G. Anthony Verboom ABSTRACT The biogeographic history of a species is a result of both stochastic processes such as dispersal and habitat filters that determine where a population with a given set of biological requirements can become es- tablished. In this dissertation, I examine the geographical and ecolog- ical distribution of the sedge tribe Schoeneae in conjunction with its inferred speciation history in order to determine the pattern of disper- sal and the environmental factors that have influenced establishment. The biogeographic reconstruction indicates numerous transoceanic dispersal events consistent with random diffusion from an Australian point of origin, but with a bias towards habitats with vegetation type and moisture regime similar to the ancestral conditions of the given subgroup (open and dry habitats in the majority of cases). The global distribution of the tribe also suggests a preference for low-nutrient soils, which I investigate at the local (microhabitat) scale by contrast- ing the distributions of the tribes Schoeneae and Cypereae on the Cape Peninsula along soil fertility axes.

We attempted to extract fossil pollen from 81 speleothems collected from 11 16 caves from the Western Australian portion of the Nullarbor Plain. Nullarbor speleothems 12 and caves are essentially “fossil” features that appear to have been preserved by very slow 13 rates of landscape change in a semi-arid landscape. Sample collection targeted fallen, well 14 preserved speleothems in multiple caves. U-Pb dates of these speleothems (Table S3) 15 ranged from late Miocene (8.19 Ma) to Middle Pleistocene (0.41 Ma), with an average age 16 of 4.11 Ma. 17 Fossil pollen typically is present in speleothems in very low concentrations, so pollen 18 processing techniques were developed to minimize contamination by modern pollen (1), but 19 also to maximize recovery, to accommodate the highly variable organic matter content of the 20 speleothems, and to remove a clay- to fine silt-sized mineral fraction present in many 21 samples, which was resistant to cold HF and which can become electrostatically attracted to 22 pollen grains, inhibiting their identification. Stalagmite and flowstone samples of 30-200 g 23 mass were first cut on a diamond rock saw in order to remove any obviously porous material. 24 All subsequent physical and chemical processes were carried out within a HEPA-filtered 25 exhausting clean air cabinet in an ISO Class 7 clean room.
