| Abstract | In der Fachliteratur werden häufig Verbißkennzahlen verwendet, die nicht operational definiert sind. Deshalb sind Vergleiche des Verbißeinflusses von Schalenwild auf die Waldvegetation oft nicht möglich oder führen zu falschen Schlußfolgerungen. Die wichtigsten Definitionskriterien für das Verbißprozent sind: Verbißobjekt, Verbißexpositionsdauer, Baumhöhe und Baumart. Beispiele für verschiedene Verbißkennzahlen sind angeführt. Auf den Unterschied zwischen Verbißeinfluß, gemessen am Verbißprozent, und Verbißschaden, gemessen am Verjüngungsziel, wird besonders hingewiesen.Different browsing indicators are used in literature but mostly they are not operationally defined. Therefore comparisons of browsing impacts by wildlife on forests are often not possible or lead to wrong conclusions. The most important definition criteria for the browsing percentage are the concrete browsing object (part of tree), the duration of possible browsing impact, the tree height, and the tree species. Some examples for browsing-indicator definitions are shown. The difference between browsing impact shown by browsing percentage, and browsing damage assessed in relation to a forest-regeneration target are highlighted.Dans la littérature on fait fréquemment mention d'indices d'abroutissement qui ne sont pas définis de façon opérationnelle. De telle sorte que les comparaisons de l'influence de l'abroutissement sur la végétation forestière par les Ongulés-gibier sont rendues impossibles ou mènent à de fausses conclusions. Les critères définissant de façon la plus objective le degré d'abroutissement sont les suivants: objet de l'abroutissement, durée d'exposition à l'abroutissement, hauteur de l'arbre et essence concernée. Des exemples sont donnés pour différents indices d'abroutissement. On insiste en particulier sur la différence entre effet de l'abroutissement, mesuré par le taux d'abroutissement, et dégât d'abroutissement, mesuré par rapport à l'objectif de régénération. |

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.
