Supplementary Submission A Proposal by Phosphate Resources Ltd East Christmas Island Phosphate Mines (Amended to Eight Sites) Christmas Island (EPBC 2001/487) Preface The submissions in this supplementary document and accompanying appendices modify, amend, update and supplement the submissions contained in the original Environmental Impact Study and ancillary submissions fi nalised and lodged on 29 December 2006. Unless otherwise specifi cally provided, in the event of any inconsistency being identifi ed between the two sets of submissions, the material contained in the supplementary document and accompanying appendices shall be deemed to prevail. Background and law His Honour Justice Buchanan by his decision of 13 October 2008 set aside in its entirety the decision of the Honourable Malcolm Turnbull on 27 April 2007 to refuse the application by Phosphate Resources Ltd ( PRL) to conduct the action of phosphate mining operations on eight areas of Christmas Island comprising some 256 hectares. The decision by the then Minister refused the application on grounds of a likely signifi cant impact on listed threatened species (ss 18 and 18A of the Environment Preservation and Biodiversity Conservation Act 1999 (EPBC Act), listed migratory species (ss 20 and 20A) and the environment where the action is on Commonwealth land (ss 26 and 27A), wetlands of international importance (ss 16 and 17B), and Commonwealth marine areas (ss 23 and 24A), but it was conceded by the Commonwealth before His Honour Justice Buchanan that “to the extent that the decision was stated to have eff ect for ss 16/17B and 23/24A it could not be sustained.” (See Para 27)1. Phosphate Resources Limited (PRL) has proceeded in this supplementary submission on the basis that the Commonwealth and its offi cers do not intend to resile from this position. The current Minister is required to consider the matter in its entirety again in accordance with the legislation (EPBC Act) as it stood before amendments eff ected by the Environment and Heritage Legislation Amendment Act (No 1) 2006 excepting that the amendments made to s134 of the EPBC Act (conditions of approval) apply to this application. The Minister must consider whether the proposed actions will have a signifi cant impact on listed threatened species (ss 18 and 18A of the EPBC Act); listed migratory species (ss 20 and 20A), and the environment, where the action is on Commonwealth land (ss 26 and 27A) in respect of each of the eight areas the subject of the application. The Minister must consider relevant impacts (which may include improvements to the environment for listed threatened species, listed migratory species and the environment resulting from action funded by revenue from the action) and the Minister must consider social and economic matters. The Minister may also attach conditions to an approval requiring specifi c activities to be undertaken for the protection of or for repairing or mitigating damage to a protected matter (whether or not the damage may be caused by the action): s.134(1), (3)(aa), (Appendix 1). Inherent in this application is a direct negation of the conclusions of the Government’s original Environmental Assessment Report (EAR). 1. Phosphate Resources Ltd v Minister for the Environment, Heritage and the Arts ( No.2) [2008] FCA1521 1 Supplementary Submission A Proposal by Phosphate Resources Ltd East Christmas Island Phosphate Mines (Amended to Eight Sites) Christmas Island (EPBC 2001/487) The EAR found that the isolated and unique nature of the Christmas Island environment, the impacts on biodiversity through previous mining, and the evidence that various species and ecosystems are already under signifi cant stress meant that it would be in the interests of the island’s biological diversity and ecological integrity that the proposal does not proceed. The proponent acknowledges that Christmas Island is unique and its ecosystem is currently under signifi cant stress. However, the proponent contends that there is no evidence that current mining operations are responsible for what appears to be a signifi cant decline in the general island ecosystem from the mid-1990s - several years after the cessation in the mid-1980s of any clearing of primary forest. There is no evidence that the proposal will contribute to current processes which are aff ecting the island’s ecosystems or have a signifi cant impact on any species. To the contrary, the proponent maintains that the commitments outlined below will make a major contribution to ameliorating, if not stabilising, the current decline of the island’s ecosystems. The broad scope of the application, especially in relation to the principles of inter-generational equity and environmental sustainability inherent in the proposal to create a trust fund for environmental and ecologically sustainable development projects, suggests that the Minister should consult widely among his ministerial colleagues in the context of his obligations under ss 131 (1) (a) and 136(2)(f) of the EPBC Act. Indeed, given the relevance of the application to the fundamental economic and social future of the island, we consider that it would be prudent to seek the views of the Ministers for Resources and Tourism, Home Aff airs, Regional Development, Defence, Employment and Workplace Relations, Immigration and Citizenship and Finance. The Statement of Reasons purported2 to have been the basis of the then Minister’s April 2007 decision was, in our submission, based essentially on unfounded assertions contained in the assessment report provided by his department (EAR). This report in large part was based on an “independent review” of the Environmental Impact Statement (EIS) prepared for it by Mattiske Consulting Pty Ltd (Mattiske) which in turn was largely based on unsupported assertions ignoring the material published in the EIS. Phosphate Resources Ltd advises that the technical advice that consequently purported to inform the Minister’s decision was inaccurate, misrepresented the proposal and its environmental impacts, and discounted environmental mitigations and off sets that would contribute to the longer-term protection of the island’s unique fl ora and fauna. Listed species A full review and response to the key technical issues in the assessment of the original EIS is set out in Appendix 2 - Response to Key Technical Issues and the accompanying Critiques of the Mattiske Report - Appendix 2A, and the EAR - Appendix 2B. They substantiate the actual position and document why it is unsafe to rely on the mix of personal opinion and unsubstantiated fi ndings in Mattiske and the EAR. Appendix 2C contains a 2009 species survey on the eight areas. Some of the key issues which are of concern to the proponent and detailed in Appendices 2, 2A, 2B and 2C are set out briefl y hereunder. 2. “... the Minister’s adoption of the explanation six weeks or so after the decision was made, does not establish that they were his reasons at that time.” : BUCHANAN J in Phosphate Resources Ltd v Minister for the Environment, Heritage and the Arts (No.2) [2008] FCA1521 at Paragraph 131. 2 Supplementary Submission A Proposal by Phosphate Resources Ltd East Christmas Island Phosphate Mines (Amended to Eight Sites) Christmas Island (EPBC 2001/487) 1. Listed threatened fl ora Christmas Island has three plant species that are listed under the EPBC Act. Two of these species occur on, or close to, individual leases proposed for mining. (a) These comprise a single individual of Asplenium listerii found on exposed limestone adjacent to MCI 70/12. The overall impact of the proposed mining activities on the one individual Asplenium listeri adjacent to MCI 70/12 was assessed as unlikely, as the fern is located on an elevated, exposed limestone cliff upwind of the proposed activities. In addition, because the species is a lithophyte, the EIS proposed to protect the microclimate of the area by a 50 metre buff er of native vegetation. The isolated location of the species and the proposed protective buff er were not taken into account nor assessed by the EAR and Mattiske. and (b) A single individual of Tectaria devexa var. minor was found by the proponent on MCI 70/8 in 2002 and it has been asserted by Parks Australia without any documented substantiation of their location, (despite repeated requests by the proponent for same), that a small population of Tectaria devexa var. minor exists in MCI 70/8. During a reconnaissance survey in February 2009 the proponent was unable to fi nd the single plant recorded in 2002. There are approximately 400 individual T. devaxa on the island of which 97% are protected in the national park. The 2002 Island Survey recommends the species’ conservation status be changed from “endangered” to “rare”. An island-wide assessment of the species was not undertaken in the EAR nor by Mattiske.

  • White Lead Tree (Leucaena Leucocephala)
    UF/IFAS Extension Hernando County Fact Sheet 2015-03 White Lead Tree (Leucaena leucocephala) Dr. William Lester, Extension Agent II • Email: [email protected] Lead tree is the common name for all members of the Leucaena genus. White lead tree refers to this particular tree’s whitish blossoms. The lead tree is native to Mexico and Central America, but it is cultivated throughout the tropics, and it has widely escaped and naturalized. In the United States, it has been reported as an adventive from Arizona, California, Florida, Hawaii, Puerto Rico, Texas and the Virgin Islands. In Hernando County the tree is mostly located along the coast, but has been found growing in alkaline soils further inland. White lead tree grows best in full sunlight and can reach heights of up to 60 feet. The leaves are alternately arranged, bipinnately compound, and typically 10 inches in length. Each leaflet is ½ inch long and spear-shaped. The bark is lightly textured and grayish-brown in color when mature. Flowers are white and grow in globe-shaped clusters at the ends of the branches, with each cluster being less than 1 inch wide. Fruits are 4- to 6-inch-long, flat pods that are 1–2 inches wide. Pods have raised edges, turn from green to brown with maturity, and contain 10–30 oval-shaped, brown seeds. In Florida, white leadtree is considered a category II invasive species, and has the potential to displace native plant communities because it is an aggressive competitor for resources. As a result, the Division of Plant Industry strictly prohibits possessing (including collecting), transporting (including importing), and cultivating this species.

  • Dear Senators
    Dear Senators, SUBMISSION I thank you for the opportunity to lodge this submission late due to the postponement of the hearing to be held. My personal and business involvement with Christmas Island goes back to 1988 when I was invited by the then Administrator, Mr Don Taylor, to visit the Island with the prospect of finding new ideas and ventures with economical benefit for the island following the end of the British Phosphate era when many residents had and were leaving the island. I commissioned a report to the Administrator utilizing 10 of the government owned vacant/empty houses in the Settlement precinct. – The proposal was to refurbish the old buildings so they could be used for the purposes of accommodation for 1. paying scientists and teams recruited from universities around the world to come and study the unique flora, fauna and oceanic conditions on – and off the island. Their research should be shared with Australian universities and research institutions. – 2. to promote, using same properties for what later became known as “Eco-tourism”. My report was well received by the Administrator and he suggested we negotiate a 90 year lease of the selected properties from the Commonwealth. At the time, before lease negotiations commenced, a political decision was made where the “vacant” houses should be offered to the people who had occupied them. – My proposal was ‘put on hold’ and later – off. Following a few further visits to the island, we purchased from the Commonwealth, in 1993 vacant block of land in Settlement and constructed three houses – known as “Barracuda Bay Chalets”.

  • Mozambique’S Actions on IAS
    1 Bioinvasion and Global Environmental Governance: The Transnational Policy Network on Invasive Alien Species Mozambique’s Actions on IAS Description1 Mozambique, officially the Republic of Mozambique, is a country in southeastern Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west and Swaziland and South Africa to the southwest. Geographically, the country is divided into two topographical regions by the Zambezi River, with hills and plateaus to the north and lowlands to the south. Mozambique has a tropical climate with two seasons, a wet season from October to March and a dry season from April to September. Almost five centuries as a Portuguese colony came to a close with independence in 1975. Large-scale emigration, economic dependence on South Africa, a severe drought, and a prolonged civil war hindered the country's development until the mid 1990's. The ruling Front for the Liberation of Mozambique (FRELIMO) party formally abandoned Marxism in 1989, and a new constitution the following year provided for multiparty elections and a free market economy. Although reforms since 1994 have improved the economic situation of many, the majority of the 21 million population remains below the poverty line. Subsistence agriculture continues to employ the vast majority of the country's work force. Mozambique is a member of the Community of Portuguese Language Countries and the Commonwealth of Nations, and an observer of the Francophonie. Overview of Biodiversity Mozambique possesses sites of high importance in regard to biodiversity such as the Gorongosa Mountains, the Great Inselberg Archipelago of Quirimbas in Northern Mozambique, and the Chimanimani Massif.

  • Status, Impact, and Recommendations for Research and Management Of
    1 Status, Impact, and Recommendations for Research and Management of Exotic Invasive Ants in Christmas Island National Park Dennis J. O’Dowd, Peter T. Green, and P.S. Lake Centre for the Analysis and Management of Biological Invasions Monash University Clayton, Victoria 3168 Report to Environment Australia 30 January 1999 2 Executive Summary 1. The exotic invasive ant, Anoplolepis gracilipes, accidentally introduced to Christmas Island sometime between 1915 and 1934, is now spreading through the undisturbed rain forest on the island. · Our limited surveys identified at least six separate infestations, ranging in area from several hectares to at least one square kilometer. · As of December 1998, the total known areal extent of infestation approximated 2-2.5 km2, comprising about 2-3 percent of all intact rain forest on the island, but a much larger fraction of shore terrace forests. · Spread can be rapid. Some “hotspots” of infestation can increase ten-fold in area over a year. Infestations may spread at three meters per day. 2. In areas of infestation, A. gracilipes forms extensive, multi-queened “supercolonies.” · Anoplolepis is a generalist consumer – a scavenger, a predator on both invertebrates and vertebrates, and it depends heavily upon honeydew produced by plant-feeding scale insects. · In areas of supercolony formation, high densities of foraging workers are sustained on the forest floor and across almost all plant surfaces, including canopy trees. Activity of foragers is continuous. · Anoplolepis colonies are thought to spread through “budding” where queens and associated workers move on foot to establish in new areas. 3. Invasion by this exotic ant destroys ecosystem integrity of rain forest on Christmas Island.

  • Mimosine Concentration in Leucaena Leucocephala Under Various Environmental Conditions
    Tropical Grasslands-Forrajes Tropicales (2019) Vol. 7(2):164–172 164 DOI: 10.17138/TGFT(7)164-172 ILC2018 Keynote paper* Mimosine concentration in Leucaena leucocephala under various environmental conditions Concentración de mimosina en Leucaena leucocephala bajo diferentes condiciones ambientales MICHAEL D.H. HONDA AND DULAL BORTHAKUR Department of Molecular Biosciences and Bioengineering, University of Hawaii at Manoa, Honolulu, HI, USA. manoa.hawaii.edu Abstract Leucaena leucocephala (leucaena) is a multipurpose tropical tree-legume that is highly resistant to many biotic and abiotic stresses. Leucaena is used primarily as an animal fodder owing to its protein-rich foliage. However, leucaena foliage also contains mimosine, a toxic non-protein amino acid that can cause alopecia, goiter and other thyroid problems, infertility and fetal death. Considering its toxicity and abundance in leucaena, it is important to quantify the mimosine concentrations in leucaena under different environmental conditions. Mimosine was extracted from various types of leucaena tissue exposed to a range of environmental conditions and then quantified by HPLC. The mimosine concentrations in leucaena treated with NaCl increased after 6 days of treatment and remained relatively high when treatment continued for 18 days. Interestingly, leucaena exposed to complete darkness for up to 5 days had a higher mimosine concentration than control plants exposed to normal light/dark photoperiods. On the other hand, drying leucaena leaflets or macerating them in an alkaline buffer significantly lowered their mimosine concentration. Mature leaflets that had fallen off the plant and dried out also contained significantly less mimosine than fresh leaflets. The results of this study indicate that mimosine concentrations in leucaena are affected by environmental conditions and this knowledge can assist in managing to prevent toxicity.
