PROPOSED GENEX KIDSTON CONNECTION PROJECT Corridor PROPOSED GENEX KIDSTON CONNECTION PROJECT Corridor Selection Report PREPARED BY QUEENSLAND ELECTRICITY TRANSMISSION CORPORATION LIMITED (ACN 078 849 233) trading as “POWERLINK” 50 3.1.4 Woody vegetation assessment The woody vegetation assessment performed by Virtual GIS, used GIS remote sensing to predict the extent of woody remnant vegetation, and the potential extent of woody remnant vegetation and regrowth vegetation in each corridor investigation area. The results of the woody vegetation mapping is useful for identifying potential areas of inconsistency between the woody vegetation assessment and the DNRM mapping, for which such areas would be targeted as part of the ground-truthing surveys during the next phase of the Project. The woody vegetation that is of potential relevance to each corridor option, as an output of remote sensing of woody vegetation, is presented on Figure 3.35–Figure 3.49. The area (ha) of dominant and sub-dominant of concern regional ecosystems that is of potential relevance to each corridor investigation area is presented in Table 3.5. The results of the analysis of woody vegetation for each corridor option is presented in Appendix G. In reference to the predicted and potential woody remnant vegetation in Table 3.5, Option C is of least constraint in terms of potential impacts upon potential and predicted of concern dominant. On the other hand, Option B is of least constraint in terms of potential impacts upon potential and predicted of concern sub- dominant regional ecosystems. However, a greater emphasis should be applied to the predicted of concern dominant remnant vegetation being of greater significance, which therefore suggests that Option C is of least ecological constraint.

  • Ba3444 MAMMAL BOOKLET FINAL.Indd
    Intot Obliv i The disappearing native mammals of northern Australia Compiled by James Fitzsimons Sarah Legge Barry Traill John Woinarski Into Oblivion? The disappearing native mammals of northern Australia 1 SUMMARY Since European settlement, the deepest loss of Australian biodiversity has been the spate of extinctions of endemic mammals. Historically, these losses occurred mostly in inland and in temperate parts of the country, and largely between 1890 and 1950. A new wave of extinctions is now threatening Australian mammals, this time in northern Australia. Many mammal species are in sharp decline across the north, even in extensive natural areas managed primarily for conservation. The main evidence of this decline comes consistently from two contrasting sources: robust scientifi c monitoring programs and more broad-scale Indigenous knowledge. The main drivers of the mammal decline in northern Australia include inappropriate fi re regimes (too much fi re) and predation by feral cats. Cane Toads are also implicated, particularly to the recent catastrophic decline of the Northern Quoll. Furthermore, some impacts are due to vegetation changes associated with the pastoral industry. Disease could also be a factor, but to date there is little evidence for or against it. Based on current trends, many native mammals will become extinct in northern Australia in the next 10-20 years, and even the largest and most iconic national parks in northern Australia will lose native mammal species. This problem needs to be solved. The fi rst step towards a solution is to recognise the problem, and this publication seeks to alert the Australian community and decision makers to this urgent issue.

  • First Phylogeny of Bitterbush Family, Picramniaceae (Picramniales)

Not much is known about most aspects of their ecology, geography, and morphology. The family is restricted to American tropics. Picramniaceae representatives are rich in secondary metabolites; some species are known to be important for pharmaceutical purposes. Traditionally, Picramniaceae was classified as a subfamily of Simaroubaceae, but from 1995 on, it has been segregated containing two genera, Picramnia and Alvaradoa, with the recent addition of a third genus, Nothotalisia, described in 2011. Only a few species of the family have been the subject of DNA-related research, and fewer than half of the species have been included in morphological phylogenetic analyses. It is clear that Picramniaceae remains a largely under-researched plant group. Here we present the first molecular phylogenetic tree of the group, based on both chloroplast and nuclear markers, widely adopted in the plant DNA barcoding. The main findings are: The family and its genera are monophyletic and Picramnia is sister to two other genera; some clades corroborate previous assumptions of relationships made on a morphological or geographical basis, while most parts of the molecular topology suggest high levels of homoplasy in the morphological evolution of Picramnia.

  • I Is the Sunda-Sahul Floristic Exchange Ongoing?
    Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared.

    Biodiversity Summary for NRM Regions Guide to Users Background What is the summary for and where does it come from? This summary has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. It highlights important elements of the biodiversity of the region in two ways: • Listing species which may be significant for management because they are found only in the region, mainly in the region, or they have a conservation status such as endangered or vulnerable. • Comparing the region to other parts of Australia in terms of the composition and distribution of its species, to suggest components of its biodiversity which may be nationally significant. The summary was produced using the Australian 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.

  • Approved Conservation Advice for Corymbia Leptoloma
    This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Approved Conservation Advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Corymbia leptoloma This Conservation Advice has been developed based on the best available information at the time this Conservation Advice was approved; this includes existing plans, records or management prescriptions for this species. Description Corymbia leptoloma, Family Myrtaceae, previously known as Eucalyptus leptoloma, is a medium sized tree growing to 20 m high. The bark is rough throughout, flaky, somewhat tessellated and yellow-grey in colour. Small branches are smooth-barked. Adult leaves are lance-shaped, 25–40 mm wide, glossy, bright green on the upper surface, and conspicuously paler below. Flowers are formed in terminal clusters. Flower buds are in groups (umbels) of seven, shortly stalked and egg-shaped, and 6–7 mm long when mature. The fruit is truncate- globose, 8–11 mm long and wide, with three cavities, and valves are deeply enclosed (Brooker & Bean, 1991; Hill & Johnson, 1995; Brooker & Kleinig, 2004). Flowering time is unknown. The related C. leichhardtii sometimes occurs in the same vicinity and can be distinguished from C. leptoloma by dull leaves that are a similar colour on both sides (CPBR, 2006). Conservation Status Corymbia leptoloma is listed as vulnerable. This species is eligible for listing as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as, prior to the commencement of the EPBC Act, it was listed as vulnerable under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth).
