| Abstract | Estimates indicate that nearly half of the world’s wetlands have been destroyed or altered as a result of human activities. However, studies investigating the impacts of land-use land cover change on wetlands have shown varied results. Furthermore, when assessing wetlands at the site level, landscapescale wetland health conditions can go largely unnoticed. The objective of this paper was to investigate wetland quality changes resulting from land-use land cover alterations at a watershed scale. Landscapepattern metrics were generated to examine changes in wetlands characteristics between 1978 and 2000 in the Muskegon River Watershed, Michigan, USA. Metrics quantifying composition, configuration, and fractal indication were generated and correlated with land-use land cover patterns and alterations. Results show ranging wetland stress with the mid-river portion of the watershed undergoing the highest fragmentation indicated by wetland patch dynamics. Landscape Shape Index, Fractal Dimension Index, and Interspersion and Juxtaposition Index metrics reflect similar spatial trends of decreasing wetlands quality. Agriculture and urban land-use composition had weak to moderate strength correlations with the Interspersion and Juxtaposition Index, respectively. The method was useful for identifying the spatial variability of wetland changes across watersheds and possible regions to focus management and monitoring efforts. |

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.
