| Abstract | The present work was conducted to assess the regeneration pattern of dominant tree species in the forested landscapes of Himachal Pradesh, India. The study was conducted in four agro-climatic zones viz., zone I, zone II, zone III and zone IV, of the state at 58 locations during 2002–2007. Stratified random quadrat sampling was employed to estimate regeneration pattern of tree species by classifying them into seedling, sapling and adult stages. The analysis of data was carried out using MS excel while it was spatially represented in Geographic Information System environment. The regeneration pattern was divided in to four classes namely good, fair, poor and no regeneration. A total of 23 forest landscape elements (LSEs) dominated by 18 tree species were observed at the surveyed localities. These tree species are representative of the western Himalayan ecosystem. The number of seedlings, saplings and adults ranged from 0 to 2,700/ha, 0 to 1,500/ha, and 20 to 1,470/ha, respectively in different LSEs. Picea smithiana was observed to posses highest number of seedlings (2,700/ha) and saplings (1,500/ha) in zone IV and zone III, respectively. Cedrus deodara, on the other hand, had the maximum number of adults (1,470/ha) in its pure patch in Shimla in zone III. The results showed that amongst the four agro-climatic zones, the zone I in general had a trend of poor to no regeneration while other zones generally had fair regeneration. Zone I and zone II had poor, fair and no regeneration pattern. The trees in zone III and zone IV had good regeneration pattern in addition to poor, fair and no regeneration. Based on the results of present study, it is suggested that efficient measures are needed to conserve and to increase the tree regeneration growth in zone I of the state, whereas special efforts should be made to maintain the luxuriant forest status in rest of the agro-climatic zones of Himachal Pradesh. |

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.
