Regional Ecosystem Technical Descriptions
Department of Science, Information Technology, Innovation and the Arts Regional Ecosystem Technical Descriptions Technical descriptions provide a detailed description of the full range in structure and floristic composition of regional ecosystems (e.g. 12.3.5) and their component vegetation communities (e.g. 12.3.5a). The descriptions are compiled using site survey data from the Queensland Herbarium’s CORVEG database. Distribution maps, representative images (if available) and the pre-clearing and remnant area (hectares) of each vegetation community derived from the regional ecosystem mapping (spatial) data are included. The technical descriptions should be used in conjunction with the fields from the regional ecosystem description database (REDD) for a full description of the regional ecosystem. Quantitative site data from relatively undisturbed sites are extracted from CORVEG and summarized to provide information specific to each vegetation community. Technical descriptions include the attributes: tree canopy height and cover and native plant species composition of the predominant layer, which are used to assess the remnant status of vegetation under the Vegetation Management Act 1999. However, as technical descriptions reflect the full range in structure and floristic composition across the climatic, natural disturbance and geographic range of the regional ecosystem, local reference sites should be used where possible (Neldner et al. 2005 section 3.3.3). The technical descriptions are subject to review and are updated as additional -

Palatability of Plants to Camels (DBIRD NT)
Technote No. 116 June 2003 Agdex No: 468/62 ISSN No: 0158-2755 The Palatability of Central Australian Plant Species to Camels Dr B. Dorges, Dr J. Heucke, Central Australian Camel Industry Association and R. Dance, Pastoral Division, Alice Springs BACKGROUND About 600,000 camels (Camelus dromedarius) are believed to inhabit the arid centre of Australia, mainly in South Australia, Western Australia and the Northern Territory. Most of these camels are feral. A small camel industry has developed, which harvests selected animals for domestic and export markets, primarily for meat. Camels can eat more than 80% of the common plant species found in Central Australia. Some plant species are actively sought by camels and may need to be protected. METHOD Observations of grazing preferences by camels were made periodically for up to 12 years on five cattle stations in Central Australia. Where camels were accustomed to the presence of humans, it was possible to observe their grazing preferences from a few metres. Radio transmitters were fitted on some camels for easy detection and observation at any time. These evaluations were used to establish a diet preference or palatability index for observed food plants. Table 1. Palatability index for camels Index Interpretation 1 only eaten when nothing else is available 2 rarely eaten 3 common food plant 4 main food plant at times 5 preferred food plant 6 highly preferred food plant 7 could be killed by camel browsing More information can be obtained from the web site of the Central Australian Camel Industry Association http://www.camelsaust.com.au 2 RESULTS Table 2. -
Recommendation of Native Species for the Reforestation of Degraded Land Using Live Staking in Antioquia and Caldas’ Departments (Colombia)
UNIVERSITÀ DEGLI STUDI DI PADOVA Department of Land, Environment Agriculture and Forestry Second Cycle Degree (MSc) in Forest Science Recommendation of native species for the reforestation of degraded land using live staking in Antioquia and Caldas’ Departments (Colombia) Supervisor Prof. Lorenzo Marini Co-supervisor Prof. Jaime Polanía Vorenberg Submitted by Alicia Pardo Moy Student N. 1218558 2019/2020 Summary Although Colombia is one of the countries with the greatest biodiversity in the world, it has many degraded areas due to agricultural and mining practices that have been carried out in recent decades. The high Andean forests are especially vulnerable to this type of soil erosion. The corporate purpose of ‘Reforestadora El Guásimo S.A.S.’ is to use wood from its plantations, but it also follows the parameters of the Forest Stewardship Council (FSC). For this reason, it carries out reforestation activities and programs and, very particularly, it is interested in carrying out ecological restoration processes in some critical sites. The study area is located between 2000 and 2750 masl and is considered a low Andean humid forest (bmh-MB). The average annual precipitation rate is 2057 mm and the average temperature is around 11 ºC. The soil has a sandy loam texture with low pH, which limits the amount of nutrients it can absorb. FAO (2014) suggests that around 10 genera are enough for a proper restoration. After a bibliographic revision, the genera chosen were Alchornea, Billia, Ficus, Inga, Meriania, Miconia, Ocotea, Protium, Prunus, Psidium, Symplocos, Tibouchina, and Weinmannia. Two inventories from 2013 and 2019, helped to determine different biodiversity indexes to check the survival of different species and to suggest the adequate characteristics of the individuals for a successful vegetative stakes reforestation. -

In Pursuit of Mobile Prey: Martu Hunting Strategies and Archaeofaunal Interpretation
AQ74(1) Bird 1/2/09 10:54 AM Page 3 IN PURSUIT OF MOBILE PREY: MARTU HUNTING STRATEGIES AND ARCHAEOFAUNAL INTERPRETATION Douglas W. Bird, Rebecca Bliege Bird, and Brian F. Codding By integrating foraging models developed in behavioral ecology with measures of variability in faunal remains, zooar- chaeological studies have made important contributions toward understanding prehistoric resource use and the dynamic interactions between humans and their prey. However, where archaeological studies are unable to quantify the costs and benefits associated with prey acquisition, they often rely on proxy measures such as prey body size, assuming it to be posi- tively correlated with return rate. To examine this hypothesis, we analyze the results of 1,347 adult foraging bouts and 649 focal follows of contemporary Martu foragers in Australia’s Western Desert. The data show that prey mobility is highly cor- related with prey body size and is inversely related to pursuit success—meaning that prey body size is often an inappropri- ate proxy measure of prey rank. This has broad implications for future studies that rely on taxonomic measures of prey abundance to examine prehistoric human ecology, including but not limited to economic intensification, socioeconomic complexity, resource sustainability, and overexploitation. Mediante la integración de modelos de forrajeo de la ecología del comportamiento con las medidas de variabilidad en restos de fauna, estudios zooarqueológicos se han realizado importantes contribuciones para entender la prehistoria del uso de los recursos y las interacciones dinámicas entre los seres humanos y sus presas. Sin embargo, cuando los estudios arqueológicos no están en condiciones de cuantificar los costes y beneficios asociados con la adquisición de presas, a menudo dependen de parámetros de sustitución como presas tamaño corporal, suponiendo que se observa una correlación positiva con la tasa de retorno. -
Science, Sentiment and Territorial Chauvinism in the Acacia Name Change Debate
9 Science, sentiment and territorial chauvinism in the acacia name change debate Christian A. Kull School of Geography and Environmental Science, Monash University, Clayton, Victoria [email protected] Haripriya Rangan Monash University, Clayton, Victoria Introduction The genus Acacia, as Peter Kershaw has often told us, may be widely present in the landscape, but its pollen is seldom found in any abundance. The pollen grains are heavy and probably not capable of long-distance transport, and even where they dominate the vegetation, their pollen is greatly under-represented. Compounding the problem, Acacia pollen tends to break up into individual units that are difficult to identify. However, as we hope to show in our contribution celebrating Peter’s work, the poor representation of acacias in palaeoenvironmental records is more than compensated by its dominating presence in what has been described as one of the longest running, most acrimonious debates in the history of botanical nomenclature (Brummitt 2011). Few would imagine botanical nomenclature to be a hotbed of passion and intrigue, but the vociferous arguments and machinations of botanists regarding the rightful ownership of the Latin genus name Acacia give an extraordinary insight into the tensions that arise when factors such as aesthetic judgement, political clout and nationalist sentiments dominate the process of scientific classification. After much lobbying and procedural wrangling, on July 16, the last day of the 2005 International Botanical Congress in Vienna, botanists approved a decision to allow an exception to the nomenclatural ‘principle of priority’ for the acacia genus. With increasing demand by botanists to split apart the massive cosmopolitan and paraphyletic genus into several monophyletic genera, the Vienna decision conserved the name acacia for the members of the new genus from Australia. -

The Prehistory of Aboriginal Landuse on the Upper Flinders River
THE PREHISTORY OF ABORIGINAL LANDUSE ON THE UPPER FLINDWS RIVER, NORTH QUEENSLAND HIGHLANDS H. J. MORWOOD Archaeology b Palaeoan tbropology The Unf versf ty of Mew England INTRODUCTION A general theme in Australian prehistory is the development of the distinctive social, economic and technological systems observed in recent Aboriginal societies. Research has demonstrated significant change in the Australian archaeological sequence and general trends of such are shared by numerous regions. Most that have been investigated indicate low density occupation during the Pleistocene and early Holocene with significant increases in site numbers, increased artefact discard rates and dissemination of new technologies and artefact types in mid-to-late Holocene times (e.g. Lourandos 1985). On the other hand, each region has a unique prehistory, range of material evidence and research potential. Our knowledge of Holocene developments in Aboriginal subsistence systems, for instance, is largely based upon the history of cycad exploitation in the Central Queensland Highlands (Beaton 1982), the appearance of seed grindstones in arid and semi- arid zones (Smith 1986) and evidence for increased emphasis on small- bodied animals in N.E. New South Wales and S.E. Queensland (McBryde 1977:233; Morwood 1987:347). The North Queensland Highlands have their own unique contribution to make concerning of Aboriginal Holocene adaptation. Partly this derives from location; the region is a largely unknown, lying in an intermediate position between S.E. Cape York Peninsula (Rosenfeld et a1 1981), the Central Queensland Highlands (Morwood 1981, 1984a), the Gulf country of N.W. Queensland (Hiscock 1984) and the Townsville area (e.g. Brayshaw 1977; Campbell 1982).
