| Abstract | The assessment of biodiversity in managed plantations has become an important issue for long-term sustainability of the ecosystem. The continuous cropping system (CCS) is common practice in Eucalyptus plantations in southern China. In order to clarify the effects of such a practice on species compositions, species diversity, and functional type compositions of understory vegetation, a field trial was installed in the first and second rotations of Eucalyptus plantations. The treatments were replicated three times and arranged in a simple completely randomized design. Vegetation surveys were performed in 1998–2005 following the treatments. Although the CCS had no significant effect on the composition structures in terms of life-form, growth-form, seed dispersal strategies and breeding strategies, there were significant differences in percent coverages of shrub (SLC) and herbaceous layer (HLC) between two types of stand. The CCS reduced the species richness and species diversity remarkably, and was also particularly favorable for r-strategy herbaceous species at the expense of k-strategy woody species in understory vegetation. The repeated disturbances to soil and vegetation including clear-cutting followed by prescribed burning and mechanical plowing maybe the main factor which results in the negative change of understory plant diversity. Although more comprehensive studies on disturbance and a long-term monitoring of a broad-scale project will be required, we suggest that alternative silviculture, consisting of practices other than clear-cutting and prescribed burning, should be introduced to conserve species composition and diversity of Eucalyptus plantations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
