Book Description
This manual summarises information on the ecology and silviculture of the species Acacia mangium Willd, with an emphasis on Vietnam. It also encompasses growth and yield data from published sources, as well as collected from sites under smallholder industrial plantations in Phu Tho Province, Vietnam. This manual is 1 of 5 that guide smallholder tree planting of 5 selected tree species in Vietnam. The other 4 species are: Acacia hybrid, Cinnamomum parthenoxylon (Jack) Meisn, Erythrophloeum fordii Oliver and Eucalyptus urophylla S.T. Blake. The Government of Vietnam is carrying out a large-scale reforestation programme, with the aim of improving local livelihood security, environmental sustainability and industrial wood supply. Smallholders are involved in plantation timber production through various schemes. Generally, these reforestation efforts have been effective, even though smallholders often lack the appropriate technical knowledge and management skills. Consequently, the quality and quantity of wood products may be suboptimal. The productivity of smallholder plantations can be improved by enhancing smallholders management knowledge and skills, including species selection (site matching), silvicultural management to produce high quality products, and pest and disease management.

Book Description
Acacia: Characteristics, Distribution and Uses opens with a chapter describing the wood of A. melanoxylon grown in Portugal in view of determining its technological quality for use in the construction and furniture industry. The characterization includes stem features, wood anatomical characteristics, chemical composition, wood density and mechanical properties.Next, the authors aim to describe and analyze common characteristics among Acacia s.l. species and to trace some parallelisms of their performance throughout several ecosystems that hold such species. It is well-known that Acacia s.l. species have the ability to fix atmospheric nitrogen and may modify soil chemistry and physics by enabling microorganisms/soil fauna to alter the microhabitat beneath the tree, and such characteristics are significant in the recovery of ecosystems.The potential of Acacia mangium, an exotic species, for restoration of a degraded land in Mt. Makiling Forest Reserve (MMFR), Philippines was also examined. Results suggested a general trend of changes in A. mangium plantation which was once a grassland dominated by Imperata cylindrica and Saccharum officinarum. Both (stems ha-1) and basal area (m2 ha-1) increased significantly in 2010-2018 (P=0.001).The authors discuss the way in which NMR spectroscopy applied to the study of gum exudates has become important since the 1990̍s in Venezuela. Analytical and structural studies of 23 species belonging to different genera and families have been reported through the combination of classic methodology for carbohydrates and NMR spectroscopy.The footprints left by evolution in the distribution of characters among current organisms have been one of the main tools in the study of organic evolution. The authors propose that the reconstruction of ancestral character states offers the possibility of knowing the changes suffered by characters in a species throughout evolutionary time.Pollinosis, also known as pollen allergy, hay fever or seasonal allergic rhinitis is one the most common respiratory disorders throughout the world. The inhalation of Acacia pollen is one of the main causes of respiratory allergic diseases in semiarid countries such as Iran, Saudi Arabia, and the United Arab Emirates. This book suggests that the recognition of allergenic components of pollens is essential for component-resolved diagnosis, the design of patient-specific immunotherapy, and the explanation of sensitization mechanisms to various allergens.The authors analyze Acacia-Pseudomyrmex mutualism which includes 15 species of acacias and a group of 10 species of mutualistic ants whose geographical distribution is similar. This relationship is frequently cited as an example of coevolution, a term that has been used to refer to the reciprocal change of interacting species where each of them acts as an agent of natural selection with respect to the other and where the reciprocal selection would result in congruent phylogenies.The concluding chapter characterizes the A. melanoxylon wood pulping performance regarding yield and kappa number as well as the pulp and paper properties. The application of fast spectroscopic technologies for pulp quality determination is also described.
