Woody Plant Species

Plant species composition according to their functional types, distribution pattern are crucial for biodiversity conservation in tropical deciduous forest. The study assessed the woody plant species diversity, stand structure and population density in the secondary deciduous forest of Chandaka wildlife sanctuary, Odisha, India. A total of 70 species belonging to 63 genera and families were documented in this study.The stem density was found to be 1080 stems/ha with reverse J-shaped population structure indicating good regeneration potential of the forests. Shannon diversity Index varied from 0 to 2.31 whereas Simpson's index varied from 0 to 0.85. The correlation study between Importance Value Index and basal area were significant (p=40.63). The present study would be helpful for conservation and management of biodiversity in secondary dry deciduous forests of Chandaka Wildlife Sanctury in particular and tropical dry forests in general.

Abstract Green roofs are expected to contribute to higher biodiversity in urban surroundings. Typically, green roofs have been designed with low plant diversity. However, plant diversity can be enhanced by controlling resource availability and creating distinct niches. Here we hypothesize that by using different drainage heights during the short plant-growing season in a semi-arid green roof system we can create distinct niches and plant communities. Our experiment took place at the University of Haifa, north Israel. We tested three different heights of drainage outlet: 10 cm under the surface of the substrate (Low), 1 cm under the surface of the substrate (Medium) and 3 cm above the surface of the substrate (High) on plant species-composition in green-roof gardens. Grasses cover was higher in High and Medium drainages while forbs cover was higher in Low drainage. Species richness was the highest in Low drainage while diversity indices showed the opposite trend. We conclude that by changing the height of the drainage we can create different niches and change species composition in a short time period of one growing season. This way we can create more diverse green roof communities and enhance biodiversity in urban areas, particularly in semi-arid regions.

Woody Plant Species

Woody plants species composition, richness, dominance and diversity in west bank forest of International Institute of Tropical Agriculture (IITA) was undertaken to understand the status of the forest. The analysis of tree species composition, richness and diversity in the forest was carried out with the aim of developing efficient management plan that will ensure biodiversity conservation. Vegetation survey using transects and plot sampling techniques were used to collect data for the study. Three transects of 500 m long each {A (270°W), B (90°E) and C (180°S)} were constructed with the aid of prismatic compass in the forest. 10 sampling plots of 10 m by 10 m each were demarcated along each transect making a total number of 30 sampling plots. In each plot, all woody plant species (trees and shrubs) with girth at breast height (gbh) greater than or equal to 10 cm (gbh ≥ 10 cm) were identified, enumerated and measured. The results showed that 581 woody plants belonging to 65 species and 28 families were encountered in the forest. The most abundant family in the forest was Fabaceae sub families of Caesalpinioidea, Mimosoideae and Palpilinoideae. The forest had Simpson diversity index (D), Shannon-Wiener (H) and Evenness index of 0.012, 0.354 and 0.195 respectively. The total density and basal area of woody plants species in the forest was 1,936.67 individuals’ ha-1 and 98.23 m2 ha−1. Newbouldia laevis had the highest density of 190 ha-1 and relative frequency of 9.811% while Milicia excelsa had the highest basal area of 40.34 m2 ha−1, relative dominance of 41.07% and Importance value index of 14.04%. The study concludes that the forest has a reasonably good tree and shrub species composition and richness, dominated by trees and a repository of many indigenous tropical woody plant species. The study recommends in-depth forest inventory, preparation of management plan and promotion of good governance in management of the forest. Also, further studies on regeneration, structure, soil seed bank, seed physiology and herbaceous plant should be carried out in the forest.
