Development of Protocol For Efficient Micropropagation of A Multipurpose Local Cultivar of Dalbergia Sissoo A Threatened Tree Species

In this study we surveyed all trees ≥10 cm diameter at breast height within 20 0.1 ha plots in a 3,500 ha forest fragment, surrounded by sugar cane fields, of the Brazilian Atlantic forest to compare tree species assemblages at the forest edge (0–100 m into forest) vs forest interior (>200 m). Plots were perpendicular to the margin. The mean number of tree species was significantly higher in the forest interior (35.4 ± SD 7.1 vs 18.4 ± SD 4.4). In addition, forest edge differed from interior in the proportion of shade-tolerant, emergent, large/very large-fruited species, and large-seeded tree species. Among the 134 tree species recorded, 24% were exclusive to the forest edge and 57% to the forest interior. Our results suggest that both the current system of protected areas and archipelagos of small fragments (1) tend to retain only a subset of the original flora, (2) will converge in terms of floristic and ecological composition (biotic simplification and homogenization), and (3) will lose rare and threatened tree species.

Fodder Trees

Information on existing tree growing practices were collected from seven villages of Morang District and six that of Dhankuta through Rural Appraisals. The tree species that the rural households were willing to introduce into their farmland have been listed. Results indicated that there is a common interest among rural households of both the Terai and Middle Hills towards growing bamboo in private farmlands. Rural households in the Terai preferred timber species such as sissoo (Dalbergia sissoo) and fruit trees which have high commercial values, whereas Middle Hills households preferred fodder trees.

Little Owl

This study was primarily focused on determining the availability of feeding niche of the little owl in University Campus. For this purpose, observations were made consecutively on the location of important sites in University Student’s Farm. This Farm is characterized by different types of tree species. Some of the important ones comprise Salmalia malabarica, Dalbergia sissoo, Cedrella toona, Terminalia arjuna and few others. The little owl mainly feeds on small insects and occasionally on very small mammals and perhaps on the small chicks. Small insects made the major portion of the diet of Athene noctua.
