In fact they're located in some of the most beautiful places on this Earth. Such as the New England National Park. A magnificent place to chomp on a chop, surroundedby rainforest and right on the edge of the Dorrigo Plateau. And home to the Eastern Bazas and Spangled Drongo plus countless other varieties of feathered and furred fauna inthis subtropical wonderland. As for our bustards, both old and young, you'll need to head west to Mootwingie, Kinchega, Sturt and Mungo. all of which offer excellent locations for a snack in the wide open spaces. N.S.W. has some extraordinary National Parks and they're there for us all to enjoy. But it wasn't always like that. Which is why the Foundation was formed. Who is the Foundation? Our full title is the National Parks and Wildlife Foundation of NSW, a non-governmentorganisation made up of members from every section of the community. We do not run national parks. The management and control of national parks is carried out by the National Parks and Wildlife Service; a government body financed from State funds. The foundation was instigated in 1970 when it became clear that the money required to save our unique animals and plants and to conduct research programmes was well beyond the reach of government funds. In effect, we provide funds for the Service by financing projects jointly formulated by the Foundation and the Service. However, being a non-government body the Foundation reserves the right to make the final decisions on all expenditures. They're welcome to join It's what you might call the people's way of becoming involved in national parks - a way in which everyone us. So are you. can play a positive role in the preservation of our natural heritage. ------I Please accept my application-- for membership--- as: -..I And we don't sell s, u pporter;,- £ n .

Over the last 0 billion years it has been subject to three separate ice ages; it has been to the tropics; it has been covered by forest; and it has supported a considerable plant and animal population both onshore and offshore. Antarctica is made up of two vastly different parts. The larger area, often called Greater or East Antarctica, consists of an old, stable landmass, most of which falls in the eastern hemis­ phere.

  • Introduction the Need for New Reserves
    Koala Strategy Submissions, PO Box A290, Sydney South NSW 1232, [email protected] CC. [email protected] 2nd March 2017. NPA SUBMISSION: WHOLE OF GOVERNMENT KOALA STRATEGY; SAVING OUR SPECIES DRAFT STRATEGY AND REVIEW OF STATE ENVIRONMENT PLANNING POLICY 44—KOALA HABITAT PROTECTION Introduction The National Parks Association of NSW (NPA), established in 1957, is a community-based organisation with over 20,000 supporters from rural, remote and urban areas across the state. NPA promotes nature conservation and evidence- based natural resource management. We have a particular interest in the protection of the State’s biodiversity and supporting ecological processes, both within and outside of the formal conservation reserve system. NPA has a long history of engagement with both government and non-government organisations on issues of park management. NPA appreciates the opportunity to comment on the whole of government koala strategy (the strategy), the Saving Our Species iconic koala project (the SOS project) and the Explanation of intended effect: State Environment and Planning Policy 44 (Koala Habitat Protection) (SEPP 44). Please note, NPA made a submission on SEPP 44 in late 2016 prior to the deadline being extended which we have reattached at the end of this document (Appendix 1). NPA was also consulted on the SOS programme in August 2016, which we greatly appreciated. We provided OEH with feedback on the programme at that time, which also contained an exploration of issues facing koalas, which we have reattached in Appendix 2. NPA has had significant input to the development of the Stand Up For Nature (SUFN) submission to this consultation.

  • Bardi Plants an Annotated List of Plants and Their Use
    H.,c H'cst. /lust JIus lH8f), 12 (:J): :317-:359 BanE Plants: An Annotated List of Plants and Their Use by the Bardi Aborigines of Dampierland, in North-western Australia \!o\a Smith and .\rpad C. Kalotast Abstract This paper presents a descriptive list of the plants identified and used by the BarcE .\borigines of the Dampierland Peninsula, north~\q:stern Australia. It is not exhaust~ ive. The information is presented in two wavs. First is an alphabetical list of Bardi names including genera and species, use, collection number and references. Second is a list arranged alphabetically according to botanical genera and species, and including family and Bardi name. Previous ethnographic research in the region, vegetation communities and aspects of seasonality (I) and taxonomy arc des~ cribed in the Introduction. Introduction At the time of European colonisation of the south~west Kimberley in the mid­ nineteenth century, the Bardi Aborigines occupied the northern tip of the Dam­ pierland Peninsula. To their east lived the island-dwelling Djawi and to the south, the ~yulnyul. Traditionally, Bardi land ownership was based on identification with a particular named huru, translated as home, earth, ground or country. Forty-six bum have been identified (Robinson 1979: 189), and individually they were owned by members of a family tracing their ownership patrilineally, and known by the bum name. Collectively, the buru fall into four regions with names which are roughly equivalent to directions: South: Olonggong; North-west: Culargon; ~orth: Adiol and East: Baniol (Figure 1). These four directional terms bear a superficial resemblance to mainland subsection kinship patterns, in that people sometimes refer to themselves according to the direction in which their land lies, and indeed 'there are.

  • The Impact of Herbivorous Insects on Australian Rainforest Tree Canopies
    Chapter 16 The impact of herbivorous insects on Australian rainforest tree canopies M.D. Lowman, Department of Ecology, Williams College, Williamstown, Massachusetts, USA formerly of the University of New England, Armidale Summary The leaf-growth dynamics of Australian rainforest tree canopies were studied over a five-year period, to determine the patterns (if any) that existed in growth, mortality, and other aspects relating to phenology and productivity of this plant community. Representative species were selected within each of the three major rainforest formations of New South Wales. These included Nothofagus moorei and Dorphora sassafras in cool temperate rainforest; D. sassafras and Ceratopetalum apetalum in warm temperate rainforest; and Dendrocnide excelsa, Dorphora sassafras, and Toona australis in subtropical rainforest. Because herbivory appeared to have such a profound effect on the survival of rainforest leaves, further investigations were conducted on this aspect of canopy growth dynamics, including herbivore abundance, diversity, and also examination of possible physical and chemical defences of leaves. Several factors were observed that led to variability in herbivory rates within different parts of the canopy: light regime, species, age of leaf, height of leaf in canopy, and sometimes individual tree or site. These factors were examined for each of the five species, with the following results. .Sun leaves were less heavily grazed than shade leaves, and also had greater tannin and phenolic contents, and greater toughness values of leaf tissue. Young leaves were significantly more intensively grazed than old leaves; for example, approximately 51 per cent leaf-area losses were experienced by young N. moorei leaves, compared with less than 1 per cent losses to old leaves.
