    Also available in:
    No results found.

    This book is about how to grow Pinus radiata (radiata pine) forest plantations. Radiata pine is a versatile, fast-growing, medium-density softwood, very suitable for a wide range of end-uses. Its silviculture is highly developed, being built on a firm foundation of over a century of research, observation and practice. It is often considered a model for growers of other plantation species. This book explores current knowledge and experience with radiata pine forest plantation management an d examines its long-term sustainability.

    Appreciation of the Chilean forest resource: Plantations of Pinus radiata and Eucalyptus sp. 1985-1996 1998
    Also available in:
    No results found.

    This report presents the calculation of the appreciation of the Chilean forest resource for the period 1985-1996. The information comes from statistics given by enterprises and projections realized by the Chilean Forest Institute (INFOR). The calculations only considered exotic forest platations (Pinus radiata and Eucalyptus species) and excluded the native forests. This report shows the methodology used and the outputs of the calculations for each species separately.

    The forest sector in the NENA region has similar ecological, social and economic contexts and functions. The NENA region is particularly vulnerable to climate change and, the climate is predicted to become even hotter and drier. Insect pests, pathogens and invasive plants can cause major damages in these ecosystems. The dieback of forest trees was caused by pests (insects and pathogens) and affects conifers, oak and Eucalypt species. Cedrus libani and Abies cilicica in Lebanon were affected by Cephalcia tannourinensis. Cedrus atlantica forests in Algeria and Morocco was affected by Thaumetopoea pityocampa and T. bonjeani. The fungus Cylindrocladium buxicola caused Boxwood Blight Buxus hyrcana in Iran. Juniperus procera in Saudi Arabia was mainly affected by fungal species, about 21 species belonging to 12 genera associated with roots and twigs were identified. The conifer seed bug, Leptoglossus occidentalis was detected on Pinus pinea, P. pinaster, P. brutia and P. halepensis in Lebanon, Morocco and Tunisia. Eucalyptus spp. of North Africa, Lebanon, Syria and Iran countries are threatened by Phoracantha semipunctata, P. recurva, Leptocybe invasa, Ophelimus maskelli and Glycaspis brimblecombei. In Sudan, dieback on Acacia nilotica was caused by silting and Roots rot belonging to Phytophtora, Pythium and Rhizoctonia genus. Deudorix livia was detected in Tunisia on Acacia farnesiana. Recently, the awful cochineal Dactylopius opuntiae was detected on Opuntia ficus-indica in Lebanon, Morocco, Jordan and Palestine. Besides these pests, the NENA region suffer from invasive plant species (trees, shrubs, herbaceous). Seventeen species were detected in Algeria, Yemen, Syria, Sudan, Saudi Arabia and Lebanon. To protect the forest against invasive species and to elaborate a specific standard approach for monitoring and management, the network in the NENA region should be standardized and the regional cooperation should be improved.
