This document provides information on two tree species: Dalbergia latifolia (Indian rosewood) and Rhododendron arboretum. It discusses the distribution, silvicultural characteristics, taxonomy, silvicultural formula, and uses of each species. For D. latifolia, it describes its distribution in the Terai and lower Himalayas, tolerance for light, frost, drought, fire, ability to coppice and root sucker, palatability to browsing animals, preference for well-drained soil, and associates in Dalbergia sissoo forest. For R. arboretum, it covers its distribution above 1500m, tolerance for light, frost, drought and fire,
