Approved Conservation Advice for Decaspermum Struckoilicum 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 Decaspermum struckoilicum 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 Decaspermum struckoilicum, Family Myrtaceae, is an erect shrub or small tree growing to 4 m high. The leaves are elliptical, 18–55 mm long, and arranged in opposite pairs along the branchlets. The flowers are borne in clusters in the leaf axils, white, with four or five petals and sepals and 16–25 stamens. The fruit is a globose berry up to 8.5 mm in diameter, soft and dark bluish-black when ripe. The plant is hairless, although there may be hairs on the new vegetative growth and on the flowers. It is similar to Decaspermum humile, differing in the matte surface of the leaves and the shorter petiole (Snow & Guymer, 2001). Prior to 2001, Decaspermum struckoilicum was known as Decaspermum sp. Mt Morgan (N.Hoy AQ55657), Decaspermum sp. 1 (Mt. Morgan) or Decaspermum sp. Mt Morgan (D.Hoy 71). Conservation Status Decaspermum struckoilicum is listed as endangered. This species is eligible for listing as endangered 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 endangered under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). It is also listed as endangered under the Nature Conservation Act 1992 (Queensland). Distribution and Habitat Decaspermum struckoilicum is known from two populations, both about 8 km east of Mount Morgan in Queensland, in the area known as Struck Oil. The northern population possibly comprises just a single plant (Queensland Herbarium, 2008). Seventeen adult and juvenile plants have been recorded for the southern population (Barry & Thomas, 1994). The species occurs in semi-evergreen vine thicket on chocolate-coloured or reddish soil (Queensland Herbarium, 2008). The tenure of locations where this species occurs is freehold and Vacant Crown Land (Barry & Thomas, 1994). Both populations occur in areas of remnant vegetation (EPA, 2008) as defined under the Vegetation Management Act 1999 (Queensland), and are therefore currently protected from broad-scale clearing. This species occurs within the Fitzroy (Queensland) Natural Resource Management Region. The distribution of this species is not known to overlap with any EPBC Act-listed threatened ecological communities. Threats The main identified threat to Decaspermum struckoilicum is weed incursion, particularly by Lantana (Lantana camara), Guinea grass (Megathyrsus maximus) and Rubber vine (Cryptostegia grandiflora) (Barry & Thomas, 1994). The main potential threats to D. struckoilicum include wildfire from adjoining sclerophyll forests, and habitat disturbance from domestic stock (Barry & Thomas, 1994). Decaspermum struckoilicum Conservation Advice - Page 1 of 3 This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Research Priorities Research priorities that would guide future regional and local priority actions include: • Design and implement a monitoring program or, if appropriate, support and enhance existing programs. • More precisely assess population size, distribution, ecological requirements and the relative impacts of threatening processes. • Undertake survey work in suitable habitat and potential habitat to locate any additional populations. • Identify appropriate intensity and interval of fire to promote seed germination or vegetation regeneration • Determine pollination, dispersal and seedling recruitment requirements for this species. • Undertake seed germination and/or vegetative propagation trials to determine the requirements for successful establishment. Regional and Local Priority Actions The following priority recovery and threat abatement actions can be done to support the recovery of Decaspermum struckoilicum. Habitat Loss, Disturbance and Modification • Monitor the progress of recovery, including the effectiveness of management actions and the need to adapt them if necessary. • Minimise adverse impacts from land use at known sites. • Investigate formal conservation arrangements, management agreements and covenants on private land, and for crown and private land investigate inclusion in reserve tenure if possible. Invasive Weeds • Implement management plans for Lantana and Rubber vine and develop and implement a management plan for Guinea grass and other invasive weeds. • Identify and remove weeds in the local area, which could become a threat to D. struckoilicum, using appropriate methods. • Manage sites to prevent introduction of invasive weeds, which could become a threat to the species, using appropriate methods. • Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact on D. struckoilicum. Trampling, Browsing or Grazing • Ensure that livestock grazing, if it occurs in the area, uses an appropriate management regime and density that does not detrimentally affect this species. • Where appropriate manage total grazing pressure at important/significant sites through exclusion fencing or other barriers. Fire • Develop and implement a suitable fire management strategy for Decaspermum. struckoilicum. • Provide maps of known occurrences to local and state Rural Fire Services and seek inclusion of mitigative measures in bush fire risk management plans, risk register and/or operation maps. Conservation Information • Raise awareness of D. struckoilicum within the local community, including distributing information sheets to community groups such as Landcare. Decaspermum struckoilicum Conservation Advice - Page 2 of 3 This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Enable Recovery of Additional Sites and/or Populations • Undertake appropriate seed collection and storage. • Investigate options for linking, enhancing or establishing additional populations. • Implement national translocation protocols (Vallee et al., 2004) if establishing additional populations is considered necessary and feasible. This list does not necessarily encompass all actions that may be of benefit to D. struckoilicum, but highlights those that are considered to be of highest priority at the time of preparing the conservation advice. Existing Plans/Management Prescriptions that are Relevant to the Species • Weeds of National Significance: Lantana (Lantana camara) (ARMCANZ, 2001), and • Rubber vine (Cryptostegia grandiflora) weed management guide (DEH, 2003).

  • TML Propagation Protocols
    PROPAGATION PROTOCOLS This document is intended as a guide for Tamborine Mountain Landcare members who wish to assist our regeneration projects by growing some of the plants needed. It is a work in progress so if you have anything to add to the protocols – for example a different but successful way of propagating and growing a particular plant – then please give it to Julie Lake so she can add it to the document. The idea is that our shared knowledge and experience can become a valuable part of TML's intellectual property as well as a useful source of knowledge for members. As there are many hundreds of plants native to Tamborine Mountain, the protocols list will take a long time to complete, with growing information for each plant added alphabetically as time permits. While the list is being compiled by those members with competence in this field, any TML member with a query about propagating a particular plant can post it on the website for other me mb e r s to answer. To date, only protocols for trees and shrubs have been compiled. Vines and ferns will be added later. Fruiting times given are usual for the species but many rainforest plants flower and fruit opportunistically, according to weather and other conditions unknown to us, thus fruit can be produced at any time of year. Finally, if anyone would like a copy of the protocols, contact Julie on [email protected] and she’ll send you one. ………………….. Growing from seed This is the best method for most plants destined for regeneration projects for it is usually fast, easy and ensures genetic diversity in the regenerated landscape.

  • 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.

Myrtle rust was first detected in Australia in April 2010 on the central coast of New South Wales. Myrtle rust originates from South America and has now also spread to other regions where Myrtaceae species are native, including New Caledonia, South Africa, Indonesia, Singapore and New Zealand. The Myrtaceae family is the largest plant family in Australia with over 2250 species and 70 genera. The species of this family make up a large proportion of iconic Australian forests such as dry and wet sclerophyll forests. The importance of studying the ecological impacts of myrtle rust in wild populations has been highlighted in multiple studies in Australia. Understanding its effects in the field will help in the prioritisation of species and environments at risk and understand how plant communities will change over time in response to myrtle rust infection.

  • Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific
    Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific Craig Costion School of Earth and Environmental Sciences Department of Ecology and Evolutionary Biology University of Adelaide Adelaide, SA 5005 Thesis by publication submitted for the degree of Doctor of Philosophy in Ecology and Evolutionary Biology July 2011 ABSTRACT This thesis advances plant biodiversity knowledge in three separate bioregions, Micronesia, the Queensland Wet Tropics, and South Australia. A systematic treatment of the endemic flora of Micronesia is presented for the first time thus advancing alpha taxonomy for the Micronesia-Polynesia biodiversity hotspot region. The recognized species boundaries are used in combination with all known botanical collections as a basis for assessing the degree of threat for the endemic plants of the Palau archipelago located at the western most edge of Micronesia’s Caroline Islands. A preliminary assessment is conducted utilizing the IUCN red list Criteria followed by a new proposed alternative methodology that enables a degree of threat to be established utilizing existing data. Historical records and archaeological evidence are reviewed to establish the minimum extent of deforestation on the islands of Palau since the arrival of humans. This enabled a quantification of population declines of the majority of plants endemic to the archipelago. In the state of South Australia, the importance of establishing concepts of endemism is emphasized even further. A thorough scientific assessment is presented on the state’s proposed biological corridor reserve network. The report highlights the exclusion from the reserve system of one of the state’s most important hotspots of plant endemism that is highly threatened from habitat fragmentation and promotes the use of biodiversity indices to guide conservation priorities in setting up reserve networks.
