The Vegetation of Robinson Crusoe Island (Isla Masatierra), Juan
The Vegetation ofRobinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile1 Josef Greimler,2,3 Patricio Lopez 5., 4 Tod F. Stuessy, 2and Thomas Dirnbiick5 Abstract: Robinson Crusoe Island of the Juan Fernandez Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation ofresources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accu rate assessment of the composition and structure of plant communities was made. We analyzed the vegetation with 106 releves (vegetation records) and subsequent Twinspan ordination and produced a detailed colored map at 1: 30,000. The resultant map units are (1) endemic upper montane forest, (2) endemic lower montane forest, (3) Ugni molinae shrubland, (4) Rubus ulmifolius Aristotelia chilensis shrubland, (5) fern assemblages, (6) Libertia chilensis assem blage, (7) Acaena argentea assemblage, (8) native grassland, (9) weed assemblages, (10) tall ruderals, and (11) cultivated Eucalyptus, Cupressus, and Pinus. Mosaic patterns consisting of several communities are recognized as mixed units: (12) combined upper and lower montane endemic forest with aliens, (13) scattered native vegetation among rocks at higher elevations, (14) scattered grassland and weeds among rocks at lower elevations, and (15) grassland with Acaena argentea. Two categories are included that are not vegetation units: (16) rocks and eroded areas, and (17) settlement and airfield. Endemic forests at lower elevations and in drier zones of the island are under strong pressure from three woody species, Aristotelia chilensis, Rubus ulmifolius, and Ugni molinae. The latter invades native forests by ascending dry slopes and ridges. -
Well-Known Plants in Each Angiosperm Order
Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers. Basal angiosperms – mostly aquatic plants Unplaced in order, placed in Amborellaceae family • Amborella trichopoda – one of the most ancient flowering plants Unplaced in order, placed in Nymphaeaceae family • Water lily • Cabomba (fanwort) • Brasenia (watershield) Ceratophyllales • Hornwort Austrobaileyales • Illicium (anise tree, star anise) Basal angiosperms - magnoliids Canellales • Drimys (winter's bark) • Tasmanian pepper Laurales • Bay laurel • Cinnamon • Avocado • Sassafras • Camphor tree • Calycanthus (sweetshrub, spicebush) • Lindera (spicebush, Benjamin bush) Magnoliales • Custard-apple • Pawpaw • guanábana (soursop) • Sugar-apple or sweetsop • Cherimoya • Magnolia • Tuliptree • Michelia • Nutmeg • Clove Piperales • Black pepper • Kava • Lizard’s tail • Aristolochia (birthwort, pipevine, Dutchman's pipe) • Asarum (wild ginger) Basal angiosperms - monocots Acorales -
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607)
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607) by Nancy Ross Preface Since it was published in 1984, Tropical Timbers of the World has proven to be an extremely valuable reference to the properties and uses of tropical woods. It has been particularly valuable for the selection of species for specific products and as a reference for properties information that is important to effective pro- cessing and utilization of several hundred of the most commercially important tropical wood timbers. If a user of the book has only a common or trade name for a species and wishes to know its properties, the user must use the index of common names beginning on page 451. However, most tropical timbers have numerous common or trade names, depending upon the major region or local area of growth; furthermore, different species may be know by the same common name. Herein lies a minor weakness in Tropical Timbers of the World. The index generally contains only the one or two most frequently used common or trade names. If the common name known to the user is not one of those listed in the index, finding the species in the text is impossible other than by searching the book page by page. This process is too laborious to be practical because some species have 20 or more common names. This supplement provides a complete index of common or trade names. This index will prevent a user from erroneously concluding that the book does not contain a specific species because the common name known to the user does not happen to be in the existing index. -

Microscopic Study on the Composites of Wood and Polypropylene*1
「森林総合研究所研究報告」(Bulletin of FFPRI),Vol. 1, No. 1 (No.382), 115-122, March, 2002 論 文(Original Article) Microscopic Study on the Composites of Wood and Polypropylene*1 FUJII Tomoyuki*2 and QIN Te-fu *3 Abstract Optical and scanning electron microscopies coupled with a thin-sectioning method and a chemical treatment to remove cell wall material were adopted to investigate morphologically the dispersion of wood fillers and the interface between the wood and polypropylene (PP) matrices in injection-molding composites. Wood fillers were well dispersed in PP matrix with a tendency toward longitudinal and concentric orientation. The interface between wood and PP was well illustrated by the chemical digestion method. It was demonstrated with this method that PP can penetrate into macro-cavities such as fiber lumina inside wood particles through cracks of inter- and intra-wall fractures and comprises a three-dimensional network within the particles and also connecting to PP matrix outside. Wood fillers were always completely isolated and covered by PP probably owing to their high wetability at their interface, although this did not directly result in stiff chemical bonding. This suggests that the chemical bonding of wood fillers and PP matrix is more important for the improvement of the adhesion properties than the surface compatibility. Keywords: composite wood, polypropylene, morphology, SEM, optical microscopy Introduction is that the resulting composites usually have a significantly reduced impact and tensile strength due to poor adhesion There has recently been a dramatic increase of interest between the hydrophilic filler material and hydrophobic in using biomass such as wood fibers, oil palm fibers and thermoplastic. -
Overview of Baltic Forest and Wood Industry | I

Internationales Holzbau-Forum IHF 2017 2 Overview of Baltic Forest and Wood Industry | I. Erele, H. Välja, K. Klauss 23. Internationales Holzbau-Forum IHF 2017 Overview of Baltic Forest and Wood Industry | I. Erele, H. Välja, K. Klauss 3 Overview of Baltic Forest and Wood Industry We can certainly call Baltic states the land of forests. Almost every inhabitant is related to forest, forestry and forest products in one or another way. Since long ago wood has been used in heating, construction, production of furniture and other household items. Today forest sector and its wood processing industry have developed into one of the most important sectors of the regional economy. And despite the fact that it occupies only 4,1% of the EU's territory, the commercial forest stock accounts for 6,3% of the EU. Forest has deep roots into Baltic States culture traditions, as well as provides opportunities for spending free time in forest hunting, in sports activities or picking berries and mush- rooms. And furthermore, there are large nature values in our forests that in some cases are unique not only on European, but also global level. However, it’s not an opportunity because it’s simply here. The forest that grows by itself represents beautiful nature values, but it becomes „the green gold” because we have learned to use and manage it wisely – by protecting nature values, by securing resources for national growth and contributing to the wellbeing of our society. -
Wood Industry Report
Wood Industry Report Submitted by Tim Jenks Prosperity Region 3 Wood Industry Proposed Five Year Action Plan Introduction The Wood Products Industries form a broad sector of business activity in Northern Michigan, and particularly in the eleven counties of Region 3. An MSU Extension study in 2012 described the forest industry as “Michigan’s third largest manufacturing sector,” supporting “about 136,000 jobs and adding $17 billion to Michigan’s economy.” (MSUE, 2012) While timber harvests could increase somewhat above their current levels, the greatest opportunity for economic growth lies in the added value provided by manufacturing wood products. Timber harvest, sawmill operations, and wood products manufacturing represent traditional industries for the people of this area of Michigan. The sector offers long- term sustainability, opportunities for positive environmental impact, and lifestyle compatibility. The actions proposed in this section will work to stabilize and maintain the existing industry, as well as to promote the establishment and growth of new entrepreneurial businesses. Overview of the Wood Products Industry Sector The “Wood Industry” sector includes a supply chain of related goods and services, ranging from harvesters to cut the trees to skilled crafts who create finished products. In addition, the sector supports large trucking operations, heavy equipment for harvesting and loading, maintenance services, and other support businesses. Harvesters Harvesters comprise a number of small businesses with a large investment in capital equipment. They sometimes own “tree farm” land, but more often bid on contracts to cut timber, either in behalf of a sawmill, or to sell independently to a sawmill. Northern Michigan’s forest lands – including extensive Federal and State holdings – continue to experience net growth every year. -
Regulation on Forest Products Processing and Marketing
Forestry Development Authority Regulation No. 112-08 Regulation on the Forest Products Processing and Marketing WHEREAS, the National Forestry Reform Law of 2006 establishes a transparent framework, for the use, management and protection of forest resources that balances the commercial, community, and conservation priorities of the Republic; and WHEREAS, the economic potential of processed wood products has not been appreciated, there has been too much exportation of crude round logs with evidence of low percentage of primary processed wood for both domestic and export market, no value-added wood product, low recovery rate of wood processing industry, problem of waste disposal; and WHEREAS, industrialization of the wood industry in general and the processing of wood into secondary/value-added products in particular are essential elements for the realization of the potential sustainable utilization of Liberia‘s forest resources; and WHEREAS, sustainable utilization of forest resources concept is not only to maintain the value of forest resources, but rather it also has a huge potential for creating employment, income and wealth for the Liberia populations; and WHEREAS, local small-scale wood enterprises are not fully capacitated and unregulated which in essence has resulted into unsustainable use and marketing of wood products, wastage of wood products, constant exposure of wood products to deteriorating agents; and WHEREAS, the lack of standard units of measurement for Liberia domestic wood market and unregulated import of wood products, -
