Current Projects:
Addison, J. (2009, under supervision) Rangeland condition and herder livelihoods in the Gobi Desert
| The Mongolian and Chinese governments are in the process of altering land tenure in the Gobi Desert from traditional open (nomadic) rangelands to fixed tenure and settled agriculture. Jane Addison's project compares the rangeland condition of the various tenure types and will make recommendations for management. |
| Many plant species in the genus Gahnia are of conservation significance (rare or endangered), and many of them are difficult to propagate in glasshouse conditions. The genus is also a significant food plant for the larvae of several endangered species of butterfly. Rina Aleman's project will compare various methods of breaking dormancy in Gahnia using temperature stratification, smoke water, and artificial ageing. Dr Phil Ainsley, Director of the Seed Conservation Centre, Adelaide Botanic Gardens (DEH) is an associate supervisor. |
| Victoria Atkinson compared three methods of revegetating waste dumps remaining after open-cut iron ore mining at Iron Baron, South Australia. Adding topsoil and direct seeding were shown to produce better results than leaving the site to regenerate without assistance. |
| Ground-based methods of assessing rangeland condition are time-consuming and expensive. Ardavan Ghorbani used satellite remote-sensing data to detect biological soil crust (BSC) cover, and showed that the data could be related to on-ground rangeland condition. |
| The Australian Defence Forces (ADF) have recently purchased agricultural land to act as a buffer between their firing range and the town of Port Wakefield, and are in the process of replanting native vegetation. Mike Heath's project compares methods of revegetation (direct seeding using high and low biodiversity seed mixes, and direct planting of tubestock). ADF, Rural Solutions SA, and the SA Dept of Water Land & Biodiversity Conservation are partners in the project. |
| Before mining commences, many mining companies stockpile topsoil and soil seedbank in piles, to be respread after the mining operation ceases. Gail Langley monitored seed viability in stockpiles of various depths, and found that most seed lost viability within a few months. Exceptions were Acacia (Leguminosae) with hard, long-lived seed, and Stipa (Graminae) whose seed required and after-ripening period. |
| Raghu Palisetty conducted grazing exclosure trials at Middleback Station, Whyalla, South Australia. His work showed that sheep are the most important herbivore in reducing survivorship of seedlings of Acacia aneura. Rabbits had a lesser and more seasonally-related effect. Kangaroos were also shown to affect survivorship of seedlings. |
