Vegetation, Floristic Composition and Species Diversity in a Tropical Mountain Nature Reserve in Southern Yunnan, SW China, with Implications for Conservation
Mongabay.com Open Access Journal - Tropical Conservation Science Vol.8 (2): 528-546, 2015 Research Article Vegetation, floristic composition and species diversity in a tropical mountain nature reserve in southern Yunnan, SW China, with implications for conservation Hua Zhu*, Chai Yong, Shisun Zhou, Hong Wang and Lichun Yan Center for Integrative Conservation, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Xue-Fu Road 88, Kunming, Yunnan 650223, P. R. China Tel.: 0086-871-65171169; Fax: 0086-871-65160916 *Corresponding author: H. Zhu, e-mail [email protected]; Fax no.: 86-871-5160916 Abstract Complete floristic and vegetation surveys were done in a newly established nature reserve on a tropical mountain in southern Yunnan. Three vegetation types in three altitudinal zones were recognized: a tropical seasonal rain forest below 1,100 m; a lower montane evergreen broad- leaved forest at 1,100-1,600 m; and a montane rain forest above 1,600 m. A total of 1,657 species of seed plants in 758 genera and 146 families were recorded from the nature reserve. Tropical families (61%) and genera (81%) comprise the majority of the flora, and tropical Asian genera make up the highest percentage, showing the close affinity of the flora with the tropical Asian (Indo-Malaysia) flora, despite the high latitude (22N). Floristic changes with altitude are conspicuous. The transition from lowland tropical seasonal rain forest dominated by mixed tropical families to lower montane forest dominated by Fagaceae and Lauraceae occurs at 1,100-1,150 m. Although the middle montane forests above 1,600 m have ‘oak-laurel’ assemblage characteristics, the temperate families Magnoliaceae and Cornaceae become dominant. -

No. 140 Irish Garden Plant Society Newsletter January 2018 Irish Heritage Daffodils Irish Heritage Daffodils IGPS Newsletter January 2018 Irish Heritage Daffodils Editorial Irish Heritage Daffodils Irish Heritage Daffodils Narcissus ‘Border Beauty’ Mary Montaut, Leinster Branch IGPS Narcissus ‘Border Beauty’ The chilly, bright winter weather just after Christmas made me really appreciate some scented subjects in the garden, especially my favourite Daphne bholua ‘Jacqueline Postil’. I was extremely fortunate many years ago to attend a propagation workshop with IGPS at Kinsealy, and they had rooted cuttings of this glorious plant. I bought one and I have adored it ever since. However, I have recently fallen in love just as passionately with another winter-scented shrub and this one, I believe, might be adopted by IGPS as one of our ‘Irish Heritage’ plants, because it is named after an Irish botanist. The shrub is Edgeworthia chrysantha - the golden-headed Edgeworthia. It belongs to the same family as the Daphne, Thymelaeaceae, and originates from the China - Nepal border area. It is naturalized in Japan, where it was planted in the late sixteenth century for paper making and is called the Paper Bush (Mitsumata). There is also an orange- flowered variety called Akebono which is said to be a smaller shrub, but I have never be lucky enough to see this one. It was first classified in 1841, and named in honour Michael Pakenham Edgeworth. He was a younger brother of the novelist, Maria Edgeworth (of Castle Rackrent fame) and lived and worked in India most of his life. However, I feel we should salute his work, and recommend this superb and tolerant shrub. -

The topmost canopy was formed by Quercus lineata, Lithocarpus pachyphyllus, Quercus lamellosa, Castanopsis tribuloides while the second layer was formed by Symplocos lucida, Caruga pinnata. The highest adult tree species were recorded of Elaeocarpus sikkimensis (119 ind/ha) followed by Daphne sp. (56 ind/ha) and Eurya acuminata (46 ind/ha). The IVI for adult tree were highest of Elaeocarpus sikkimensis (19.4) followed by Eurya acuminata was highest for herbs (1.66), trees (1.54) and shrubs (1.19). Raunkiaer’s life (׳and Castanopsis hystrix (13.1). The species diversity (H (17.1) form assessment showed phanerophytes as the largest life forms (44.85%) followed by Chamaephytes (32.35%) and Geophytes (14.70%) indicating the prevalence of a phanerophytic phytoclimate in Fambong lho wildlife sanctuary (WS). The poor regeneration of oak as compared to Eurya acuminata (50.9 ind/ha), Symplocos lucida (30.9 ind/ha) indicates a high chances of change in species compositon and vegetation structure in the future. 1.

Fl. China 11: 516–553. 2008. 2. ACER Linnaeus, Sp. Pl. 2: 1054. 1753. 枫属 feng shu Trees or shrubs. Leaves mostly simple and palmately lobed or at least palmately veined, in a few species pinnately veined and entire or toothed, or pinnately or palmately 3–5-foliolate. Inflorescence corymbiform or umbelliform, sometimes racemose or large paniculate. Sepals (4 or)5, rarely 6. Petals (4 or)5, rarely 6, seldom absent. Stamens (4 or 5 or)8(or 10 or 12); filaments distinct. Carpels 2; ovules (1 or)2 per locule. Fruit a winged schizocarp, commonly a double samara, usually 1-seeded; embryo oily or starchy, radicle elongate, cotyledons 2, green, flat or plicate; endosperm absent. 2n = 26. About 129 species: widespread in both temperate and tropical regions of N Africa, Asia, Europe, and Central and North America; 99 species (61 endemic, three introduced) in China. Acer lanceolatum Molliard (Bull. Soc. Bot. France 50: 134. 1903), described from Guangxi, is an uncertain species and is therefore not accepted here. The type specimen, in Berlin (B), has been destroyed. Up to now, no additional specimens have been found that could help clarify the application of this name. Worldwide, Japanese maples are famous for their autumn color, and there are over 400 cultivars. Also, many Chinese maple trees have beautiful autumn colors and have been cultivated widely in Chinese gardens, such as Acer buergerianum, A. davidii, A. duplicatoserratum, A. griseum, A. pictum, A. tataricum subsp. ginnala, A. triflorum, A. truncatum, and A. wilsonii. In winter, the snake-bark maples (A. davidii and its relatives) and paper-bark maple (A. -

Accepted 1 March, 2012 In vitro a ntioxidative properties of methanol, chloroform and diethyl ether extracts of the leaves of Daphniphyllum chartaceum Rosenthal. were examined spectrophotometrically. In vitro antioxidant activity of all the extracts were determined by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity assay, reducing power assay, hydrogen peroxide (H2O2) scavenging activity and total phenol content. Among all the three extracts, diethyl ether showed highest DPPH scavenging (32.78±0.11) at a concentration of 1000 µg/ml and reducing power activity (0.908±0.013). The methanolic extract exhibited higher phenolic content (0.19±0.013 mg/ml catechol equivalent) and as a result, there was an enhanced H 2O2 scavenging activity (27.93±0.47), followed by the chloroform extract. The observations from this study suggest the potentiality of D. chartaceum , which could be commercially exploited by the pharmaceutical industry as a natural antioxidant. Key words: In vitro antioxidative activity, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay, reducing power assay, natural antioxidant.
