Synopsis (short abstract) Insect pests, diseases and other biotic agents have considerable impacts on forests and the forest sector. They can adversely affect tree growth and the yield of wood and non-wood products. Damage caused by forest pests can significantly reduce wildlife habitat thereby reducing local biodiversity and species richness. They can alter natural forest landscapes by decimating one or more tree species as has been observed in eastern American forests as a result of chestnut blight and throughout the Northern Hemisphere because of Dutch elm disease. Some pests have necessitated changes in management regimes often forcing forest managers to switch to alternative tree species in plantations; for example, the failed attempts in many parts of the world to establish mahogany plantations because of the presence of mahogany shoot borers ( Hypsipyla spp.). Pathogens may also limit the sites on which species can be gro wn successfully outside their natural range as has been experienced with red band needle blight (Mycosphaerella pini) and western gall rust (Endocronartium harknessii)infecting Pinus radiata.

    Sustainable management of Pinus radiata plantations 2013

    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.

    FAO TO PROTECT CHESTNUT FORESTS IN TURKEY USING CLASSICAL BIOLOGICAL CONTROL METHODS 2017

    Chestnut (Castanea species) are trees providing crucial resources for livelihoods in many parts of the world, with a wide range of economic, social and environmental benefits. The Asian chestnut gall wasp (ACGW) Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) is considered to be one of the most harmful insect pests of chestnut varieties in the world and can cause serious damage. However, protecting forest health from ACGW is possible using Integrated Pest Management (IPM) principles inc luding classical biological control methods.

    Forest invasive species in the NENA Region
    XV World Forestry Congress, 2-6 May 2022

    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.
