Conifer Plantation

The effects of conifer plantation management and forest fragmentation on plant species diversity in Japan were reviewed. While most studies have demonstrated that the practice of thinning in coniferous plantations can enhance species diversity of naturally regenerated trees, such as broad-leaved trees, some have shown that thinning reduces plant species diversity through the direct physical disturbance to forests. In addition, plant species diversity in plantations has also been shown to be dependent on the distance from seed sources. Extensive forest fragmentation due to land use changes has occurred, particularly in forests near urban and suburban areas. Although the number of species per unit area in abandoned coppice forests is not clearly related to the extent of forest fragmentation, most species attributes (such as rare species) are negatively influenced by forest fragmentation. Some of the forests owned by shrines and temples in urban areas are similar to island forests and are relatively well protected from human disturbance. To more clearly understand and evaluate changes in biodiversity through forest management, elucidating the interactions between management and plant species diversity, species composition, and the ecological traits of various species is therefore necessary.

Shorea Robusta

The Sal (Shorea robusta) dominated forest vegetation of Dalma Wildlife Sanctuary, West Singhbhum, Jharkhand, India was explored to evaluate the diversity and vegetation structure through different phyto-sociological attributes. The knowledge of the structure and composition of the plant communities has enormous significance in conservation of managed forests, therefore, the plant species diversity, structure and importance value index (IVI) at various levels, viz., trees, shrubs and herbs were studied. A total of 153 plant species (66 trees, 30 shrubs and 57 herbs) belonging to 124 genera of 51 families were recorded from the 30 random plots marked for sampling within the sanctuary. The IVI was highest in Shorea robusta (40.87) and lowest in Syzygium salicifolium (1.08). Shannon-Weaver’s diversity index was recorded highest in herbaceous species (3.66) than in trees (3.08) and shrubs (2.66). Simpson’s index was highest in trees (0.106) than in shrubs (0.035) and herbs (0.028). Pielou’s index was found highest in herbs (0.064) than in shrubs (0.048) and trees (0.046) which was within the range reported for different Indian forests and also which indicates that the sanctuary exhibits species diverse forest. The result of plant species diversity and their quantitative features reveal that the overall community is heterogeneous.
