In Fiji, the endangered Fijian crested iguana (Brachylophus vitiensis) is endemic to tropical dry forests. Yadua Taba Island contains one of the best remaining stands of tropical dry forest in the Pacific along with the largest (and only secure) population of B. vitiensis in Fiji and has been proposed as a translocation source for iguana conservation. In this study we determined the major vegetation types on Yadua Taba and identified forest habitat preferences of B. vitiensis to (1) characterize the island’s habitats for tropical dry forest regeneration monitoring and (2) understand which forest types are preferred by iguanas for future translocation projects. Vegetation data were collected using reconnaissance, entitation, line transects, and aerial photos. Iguana abundance data were collected by nocturnal surveys of permanent transects. Six major vegetation types were identified of which tropical dry forest was the largest (46% of the island), followed by a combination of rocky cliff–shrubland/grassland vegetation (26%). Our conservative estimate of B. vitiensis population size on Yadua Taba is 12,000 iguanas, the majority of which occur in tropical dry forest. Superabundance of the dry forest understory tree Vavaea amicorum, the favorite fruit species of iguanas, may help account for the high density of iguanas observed. These results highlight the ecological link between tropical dry forest and B. vitiensis and emphasize the importance of rehabilitation or conservation of tropical dry forest habitat in potential iguana translocation sites as part of the management plan for B. vitiensis throughout the Fiji Islands

    Plant use in the Nepal Himalaya, recorded in the 6500-year-old text of the Rigveda, ranks among the earliest uses of medicinal plants (Malla and Shakya 1984). Another early account, the Saushrut Nighantu, is perhaps the oldest Nepali medicinal plant book, which was produced during the rule of the Great King Mandev in the fifth century, and records the uses of 278 Nepalese medicinal plants (Subedi and Tiwari 2000; Gewali and Awale 2008). Later compendia of herbal pharmacopoeias such as Chandra Nighantu and Nepali Nighantu published in the nineteenth and twentieth centuries, respectively, described 750 plants and 971 articles (IUCN Nepal 2004)
