| Abstract | Most propagule bank research has been conducted in rural areas and has emphasised agricultural soils, although research on rural riparian propagule banks has expanded rapidly over the last decade. This paper presents observations of the species abundance of plant propagules in urban riparian soils along the River Brent, Greater London, UK. The data are analysed to explore changes in species abundance of the propagule bank with depth (0–5 cm compared with 5–10 cm soil layer), with distance from the river (0–1 m, 1–2 m, 2–3 m), and at different locations on the river network. No significant differences were found in propagule abundance with soil depth or distance from the river’s edge, but significantly more species were found in the propagule bank close to the river’s edge. The species composition of the Brent’s propagule bank is then compared with riparian propagule banks from the rural rivers Dove, Frome and Tern, UK. Species richness of the Brent propagule bank samples was generally lower than was found in the three rural rivers and, in total, 21%, 4%, 5% and 4% of observed species were aliens in the Brent, Dove, Frome and Tern soil samples, respectively. When the species present in the Brent’s propagule bank were compared with published data on urban garden soils in another UK city, the latter were found to support a higher number of alien species, suggesting that other propagule sources to urban river systems support lower numbers of alien species in riparian zones than domestic gardens. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
