Tuscan Solid Wood Worksurfaces
solid wood worksurfaces Tuscan solid wood worksurfaces Touch a solid wood worksurface and you can feel the beauty with your fingertips. Solid wood worksurfaces are an investment in timeless quality and natural beauty. Tuscan worksurfaces are crafted from the finest quality hardwoods, so you can always be confident about their performance and durability. And the extensive choice of colours and species, available in different sizes and thicknesses, gives you unrivalled design freedom. Your choice of timber will be instinctive. But the look and feel of your worksurface will always be special. Bamboo 3 Species & Trees Bamboo - Phyllostachys Pubescens European Oak - Quercus Robur, Quercus Petrea Technically not a wood but a species of grass, it is widely European Oak is light to yellowish-brown in colour with used in a vast number of applications due to its structural distinctive silver grain figure due to the broad medullary and durable qualities. It is very dense and strong with rays that can appear. Renowned for it’s strength, durability excellent resistance to moisture. Due to its exceptional and aesthetic character, it is a preferred choice in a wide growth rate, bamboo is now widely regarded as one range of applications. of the most sustainable and environmentally friendly options available. Iroko - Chlorophora Excelsa The excellent strength and natural oil durability properties Brown Ash - Fraxinus Excelsior of Iroko make it an excellent choice for worktops, as well European Ash is of medium weight, with freshly cut as being one of the most interesting and striking timbers wood being a creamy white to pale brown, turning to to use. -

CHARACTERISTICS OF TEN TROPICAL HARDWOODS FROM CERTIFIED FORESTS IN BOLIVIA PART I WEATHERING CHARACTERISTICS AND DIMENSIONAL CHANGE R. Sam Williams Supervisory Research Chemist Regis Miller Botanist and John Gangstad Technician USDA Forest Service Forest Products Laboratory1 Madison, WI 53705-2398 (Received July 2000) ABSTRACT Ten tropical hardwoods from Bolivia were evaluated for weathering performance (erosion rate, dimensional stability, warping, surface checking, and splitting). The wood species were Amburana crarensis (roble), Anudenanthera macrocarpa (curupau), Aspidosperma cylindrocarpon Cjichituriqui), Astronium urundeuva (cuchi), Caesalpinia cf. pluviosa (momoqui), Diplotropis purpurea (sucupira), Guihourriu chodatiuna (sirari), Phyllostylon rhamnoides (cuta), Schinopsis cf. quebracho-colorudo (soto), and Tabeb~liuspp. (lapacho group) (tajibo or ipe). Eucalyptus marginatu Cjarrah) from Australia and Tectonu grandis (teak), both naturally grown from Burma and plantation-grown from Central America, were included in the study for comparison. The dimensional change for the species from Bolivia, commensurate with a change in relative humidity (RH) from 30% to 90%, varied from about 1.6% and 2.0% (radial and tangential directions) for Arnburunu cer~ren.risto 2.2% and 4.1% (radial and tangential) for Anadenanthera macrocarpu. The dimensional change for teak was 1.3% and 2.5% (radial and tangential) for the same change in relative humidity. None of the Bolivian species was completely free of warp or surface checks; however, Anadenanthera macrocarpu, Aspidosperma cy- lindrocurpon, and Schinopsis cf. quebracho-colorado performed almost as well as teak. The erosion rate of several of the wood species was considerably slower than that of teak, and there was little correlation between wood density and erosion rate. Part 2 of this report will include information on the decay resistance (natural durability) of these species. -

Medina , Jose Hermis P. Patricio, and Angela Grace Toledo-Bruno Department of Environmental Science, College of Forestry and Environmental Science Central Mindanao University, University Town, Musuan, Bukidnon, Philippines Abstract. Aside from the greenhouse gas reduction ability of palm oil-based biofuel as alternative to fossil fuels, another essential greenhouse gas mitigation ability of oil palm plantation is in terms of offsetting anthropogenic carbon emissions through carbon sequestration. In this context, this study was done to determine the carbon sequestration potential of oil palm plantations specifically in two areas in Mindanao, Philippines. Allometric equation was used in calculating the biomass of oil palm trunk. Furthermore, destructive methods were used to determine the biomass in other oil palm parts (fronds, leaves, and fruits). Carbon stocks from the other carbon pools in the oil palm plantations were measured which includes understory, litterfall, and soil. Results revealed that the average carbon stock in the oil palm plantations is 40.33 tC/ha. Majority of the carbon stock is found in the oil palm plant (53%), followed by soil (38%), litterfall (6%), and understory, (4%). The average carbon sequestration rate of oil palm plants is estimated to be 4.55 tC/ha/year. -
Selling Your Timber
Selling Your Timber A timber sale is a serious matter requiring careful preparation. The results of many years of past timber growth are at stake, and the condition of the forest after the sale profoundly affects its productivity for many years to come.

Wildland fire in ecosystems: fire and nonnative invasive plants. Gen. Tech. Rep. RMRS-GTR-42-vol. 6. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 355 p. Abstract—This state-of-knowledge review of information on relationships between wildland fire and nonnative invasive plants can assist fire managers and other land managers concerned with prevention, detection, and eradi- cation or control of nonnative invasive plants. The 16 chapters in this volume synthesize ecological and botanical principles regarding relationships between wildland fire and nonnative invasive plants, identify the nonnative invasive species currently of greatest concern in major bioregions of the United States, and describe emerging fire-invasive issues in each bioregion and throughout the nation. This volume can help increase understanding of plant invasions and fire and can be used in fire management and ecosystem-based management planning. The volume’s first part summarizes fundamental concepts regarding fire effects on invasions by nonnative plants, effects of plant invasions on fuels and fire regimes, and use of fire to control plant invasions. The second part identifies the nonnative invasive species of greatest concern and synthesizes information on the three topics covered in part one for nonnative inva- sives in seven major bioregions of the United States: Northeast, Southeast, Central, Interior West, Southwest Coastal, Northwest Coastal (including Alaska), and Hawaiian Islands. -
