| Abstract | Effects of colony nesting of herons on soil properties and herb layer composition in Pinus densiflora forest were studied at Pomaeri, Kangwon Province in Korea. Herons have used this habitat as a nesting site from January to October every year. In 1995, more than 500 herons were observed in this habitat. Nutrient content of soil was much higher at the nesting site than that of the non-nesting site (control). Total nitrogen concentration of soil at the nesting site and the control site was 14.8±1.85 mg g$^{-1}$ and 2.8±0.35 mg g$^{-1}$, respectively. Phosphorus content of soil in the nesting site was 32 times greater than that of the control site. This is evidently due to the addition of feces of the herons, and decomposition of thin twigs and organic debris from the canopy of dead trees and bird nests. Light intensity at herb layer of the nesting site and of the control site was 80% and 20%, respectively, of incident on outside forest. Species diversity of herb layer in the nesting site (9 species) was quite lower than that in the control site (14 species). Similarity index of the herb layer between the two sites was 0.07. The nesting site was dominated by indicator species of soil eutrophication such as Humulus japonicus, Persicaria perfoliata, Persicaria fauriei, Commelina communis, Chelidonium majus var. asiaticum. Changes of herb species composition in the nesting site was evidently due to the eutrophication of the soil and increased light intensity of the herb layer. |

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.
