Professor Stephen Nortcliff, Secretary General of the IUSS, hascontributed a general report on the overall success of the 18th
WCSS in this issue (Nortcliff 2006), and Dr. Stefan Norra, Sub-ject Editor for 'Urban Soils' in this journal, has featured theSymposium on 'Urban Soils' at the WCSS (Norra 2006). TheOral and Poster Sessions of Working Group 'Forest Soils' –Evaluating Management Impacts on Forest Soils – are high-lighted in this report. The Sessions examined recent advancesin the development and application of innovative technologies(e.g. stable isotopes, bio-molecular, nuclear magnetic resonance,geographic information systems, and ecosystem modelling) forassessing the management impacts on forest soil processes andproperties, particularly in relation to carbon and nutrient cy-cling in the context of global climate change. The Sessions re-ported the success and limitations of both conventional andadvanced technologies.
There were 5 papers presented at the Oral Session of ForestSoils, 18 brief oral presentations at the Poster Theatre Session,and 39 poster papers at the regular Poster Session. The Ses-sions were jointly chaired by Professor Zhihong Xu and Pro-fessor Chris Johnson, Syracuse University, New York, USA.
Oral presentations
• Dr. Caroline Preston, Canadian Forest Services, presented akeynote 'Some chemical and spectroscopic approaches to evalu-ating management impacts on forest soil organic matter'.
• Dr. Thomas Fox, Virginia Polytechnic Institute and StateUniversity, USA, gave an oral presentation 'Precision for-estry in the 21st century: linking climate, geology, topogra-phy, soils, and ecophysiology to develop site specific esti-mates of forest productivity for pine and eucalyptus in northand south America'.
• Three platform presentations followed: 1. 'Methodologicalstandards to detect forest soil carbon stocks and stockchanges at landscape scales' by Dr Rainer Baritz (Germany)and his European colleagues. 2. '13C differentiation betweendissolved and solid organic carbon in soils as induced bysubstitution of a native deciduous forest by a coniferous for-est' by Suchet et al. (France). 3. 'Microbial functional diver-sity – Assessing impacts of forest management practices' byLalor et al. (Australia).
Poster presentations
One of the interesting features at the 18th WCSS was the 'PosterTheatre Session', with selected poster papers to be presented orallyfor 5–20 min per contribution. At the Poster Theatre Session ofForest Soils, there were 18 selected poster papers (Box 1). Theauthors had 5–8 min time to introduce and briefly discuss them,in addition to the regular poster display at the WCSS. Another39 posters were displayed during the regular poster show.
Results
In total, there were 64 papers presented at the Forest Soil Ses-sions from Australia, Belgium, Brazil, Canada, China, Croatia,France, Germany, Japan, India, Italy, New Zealand, Parana,Russia, Spain, and the USA.At the Business Meeting of Forest Soils Working Group, Pro-fessor Zhihong Xu has been elected as the Chair of the Work-ing Group for the next 4 years in front of the 19th WCSS whichwill be held in Brisbane, Australia, in early August 2010.Professor Xu and his colleagues will organize the 'InternationalSymposium on Forest Soils and Ecosystem Health: Linking LocalManagement to Global Change Challenges', 19–23 August2007, Sunshine Coast, Queensland, Australia.
