East Indian Mahogany Chukrasia Velutina Invasive plant East Indian mahogany Chukrasia velutina East Indian mahogany is a dominant native of high rainfall Leaves are compound, alternate, pinnate with 4–9 pairs lowland forest from Bangladesh to Thailand. Regarded as of alternate hairy leaflets without an end leaflet. a pioneer species, it can colonise bare ground and road cuttings in its natural range. Large yellowish-white flowers appear on stalks in the leaf axils or at the ends of branches. Capsules are large The species was introduced to the Atherton Tableland (4 cm × 3.5 cm), rounded, woody and contain 60–100 and Mulgrave Valley in the 1960s as a cabinet timber. It seeds, which are winged at one end. has prolific seed production and a tremendous potential for spread through wind-borne seeds.

  • Performance of a Five-Year-Old Provenance Trial of Chukrasia in the Northern Territory, Australia
    Prospects for high-value hardwood timber plantations in the 'dry' tropics of northern Australia, Mareeba, 19th – 21st October 2004. Performance of a five-year-old provenance trial of Chukrasia in the Northern Territory, Australia. Brian Gunn, Kron Aken & Khongsak Pinyopusarerk CSIRO Forestry and Forest Products PO Box E4008 Kingston ACT 2604 Abstract Keywords: provenance variation, volume growth, suckering, termite resistance, distribution, stem form, bark character A provenance trial of Chukrasia A. Juss. was established at Berry Springs near Darwin in the Northern Territory of Australia to assess the potential of this species as a commercial plantation tree for the production of high value wood. The trial comprised 16 seed sources from the species natural distribution in China, Laos, Myanmar, Thailand, Vietnam, and from a local planted stand in Darwin probably of Sri Lanka origin. In order to gauge the performance of the species, assessments of height and diameter growth; axis persistence associated with apical dominance and single stem growth; stem straightness; bark character and incidence of suckering and termite damage were made when the trial was 5.4 years old. Survival varied considerably among provenances but differences were not significant, nor for stem straightness score. There were significant differences between seed sources in growth traits with seedlots from deciduous forest environments associated with the rough corky bark C. velutina growing faster than the smooth barked C. tabularis from the moister ecological environments. The seed source from Darwin had less than one fifth of the volume of the most productive provenance. Axis persistence, bark characteristics and other traits assessed all showed significant differences.

Until Page 2 of 13 now, major species to be planted and given results are Eucalyptus, Acacia spp, Pinus massoniana and Casuarina equisetifolia. All of them are exotic tree species. The only suitable indigenous species is Pinus merkusii. Besides, in some areas the Pinus kesya is also planted. Plantation of broadleaves species has been applied for some decades. Main sites are forestland-characterized soils. Two major species with large planting percentage are Manglietia glauca and Styrax Tonkinensis. Other species are planted scatterly in many ecological zones, accounting for small or tiny percentage. In general, broadleaves tree species are much less in comparison with exotic tree species. Afforestation project is being executed on sandy soil and bare land, denuded hills of 3 provinces: Ha Tinh, Quang Binh, Quang Tri.

  • Changes in Sensitivity of Tree-Ring Widths to Climate in a Tropical Moist Forest Tree in Bangladesh
    Article Changes in Sensitivity of Tree-Ring Widths to Climate in a Tropical Moist Forest Tree in Bangladesh Mizanur Rahman 1,2,* , Mahmuda Islam 1,2, Jakob Wernicke 1 and Achim Bräuning 1 1 Institute of Geography, Department of Geography and Geosciences, Friedrich-Alexander University Erlangen-Nuremberg, 91058 Erlangen, Germany; [email protected] (M.I.); [email protected] (J.W.); [email protected] (A.B.) 2 Department of Forestry and Environmental Science, Shahjalal University of Science and Technology, Sylhet 3114, Bangladesh * Correspondence: [email protected]; Tel.: +49-91318522656 Received: 8 November 2018; Accepted: 2 December 2018; Published: 6 December 2018 Abstract: Tree growth in the tropics is strongly influenced by climate. However, reported tree growth responses to climate are largely inconsistent, varying with geographic location, forest type, and tree species. It is thus important to study the growth responses of tropical trees in sites and species that are under-represented so far. Bangladesh, a country influenced by the Asian monsoon climate, is understudied in terms of tree growth response to climate. In the present study, we developed a 121-year-long regional ring-width index chronology of Chukrasia tabularis A. Juss. sampled in two moist forest sites in Bangladesh to investigate tree growth responses to climate in monsoon South Asia. Standard dendrochronological methods were used to produce the ring-width chronologies. The climate sensitivity of C. tabularis was assessed through bootstrap correlation analysis and the stationarity and consistency of climate–growth relationships was evaluated using moving correlation functions and comparing the regression slopes of two sub-periods (1950–1985 and 1986–2015).
