Actinorhizal symbiotic micro-organisms that live in root nodules and plants are trees which can input a huge amount of nitrogen to convert atmospheric nitrogen into a usable form. Put in the ecosystem through symbiotic nitrogen (N2) fixation simple words, NFT species do not depend solely on process with filamentous soil bacteria (Frankia). The N2 which is fixed by actinorhizal plants is comparable to the that available nitrogen in the soils like non-NFT species. The fixed by legumes. Casuarina species are the most important majority of more than 15,000 species in the family actinorhizal plants in the tropics and sub-tropics. Leguminosae and in other families such as Casuarinaceae and Elaegnaceae are known to fix nitrogen. It is therefore not uncommon for NFT species to find their way into all forms of planting for a wide variety of products and services. Members will notice a new IUFRO logo on this cover page. The IUFRO board agreed to adopt this new logo as part of its strategy that aims at showing IUFRO as a modern organisation. This followed a word change ‘forestry’ to ‘forest’ in the name of this organisation. I take this opportunity to welcome many new members of this IUFRO Working Party. Please feel free to use this newsletter as a venue for sharing information and your experiences on NFT species with other members and public audiences.

  • BIODIVERSITY CONSERVATION on the TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and Plants
    BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands.

Lu South China Botanical Garden, Chinese Academy of Sciences, Guangzhou 510650, China Received March 2003 PENG, S. L., LIU, J. & LU, H. F. 2005. Characteristics and role of Acacia auriculiformis on vegetation restoration in lower subtropics of China. Acacia auriculiformis was introduced to degraded lower subtropical China for vegetation restoration. A long- term case study showed that these trees grew fast and formed forest cover in the degraded land. The leaf area, efficiency of solar radiation utilization, biomass as well as productivity of the forests reached a high level and the soil fertility was improved through nitrogen fixation of tree roots. Acacia auriculiformis communities reconstructed the habitat in degraded areas, which provided appropriate settlement conditions for native species and the whole community was in advanced succession. However, with the development of community structure, A. auriculiformis showed indication of decline gradually due to the changing environment and unsuccessful self-regeneration. They would be replaced increasingly by native species which adapt to the changed habitat. As exotic species, A. auriculiformis was demonstrated to be a safe and ideal tree for vegetation restoration in degraded lower subtropics. However, it can be considered only as pioneer species and some forest reconstruction measures should be taken to accelerate the process of restoration.

Cunn. ex Benth and their natural hybrid, A. mangium x A. auriculiformis , are important plantation species for timber production in the tropics. However, their potential to invade natural ecosystems has been a concern because of their prolific production of long-lived seeds. Deployment of triploid Acacia clones in plantations might reduce fertility and associated weed risk.
