    Strengthening the Resilience of Pine Forests to Bark Beetle Outbreaks and Associated Dieback - TCP/RER/3801 2024

    Extensive forest coverage in Belarus and Ukraine provides a fundamental contribution to the wellbeing of rural populations and the national economies, with forestry and the wood processing industry accounting for 2.2 percent of the gross domestic product (GDP) of Belarus and 1 percent of the GDP of Ukraine. Both countries have significant potential for expansion of the forestry sector, which is, however, limited by certain factors related to the global environmental processes, resulting in a highly increased proportion of dying forest stands and damage to trees by pests and diseases. Of particular concern in the area is the fact that native pine forests and older plantations are currently suffering from dieback, caused by outbreaks of bark beetles. These insects usually attack dead or dying trees and serve as primary decomposers. However, under stressful conditions, such as drought or high tree density, they can attack and destroy healthy trees in large numbers, overcoming tree defences and severely damaging entire forests. Due to the limited institutional capacities in forest health, the governments of the two countries requested technical assistance from the Food and Agriculture Organization of the United Nations (FAO) in implementing an emergency action plan for combating dieback of pine forests and developing a long-term coordinated solution to reduce and control the periodic incidence of bark beetle infestations.

    Gains from a good tree improvement program (starting with species/provenance matching to site) can usually result in considerable gain in wood yields from tropical forest plantations. Optimal nursery and silvicultural practices (including seed pre-treatment, application of nitrogen-fixing soil micro-organisms, optimal spacing for defined end use, selection of adequate site, fertilization, and irrigation) can considerably increase such gains further. This report summarizes literature on gains tha t might be expected by implementing tree improvements and optimal silvicultural practices for acacias, eucalypts, teak and pines in tropical areas. Results are presented for each genus in turn, first examining factors common to all the genera, and then focusing on unique factors. The data on tree-growth gains are extremely variable from study to study. They range from virtually no favourable response to tree improvement and optimal silviculture, to gains of many hundreds of percent over c ontrols. This of course complicates the matter of using such data in global fibre supply modelling.

    Non-wood forest products in international statistical systems 2017
    Also available in:
    No results found.

    This report compares the international statistics on non-wood forest products (NWFPs) by review-ing the three main international statistical classifications: the Harmonized System (HS), the Central Product Classification (CPC) and the International Standard Industrial Classification (ISIC). It dis-cusses specific issues in linking major NWFPs across the three reference systems, as well as how countries deal with these issues. It proposes ways for improving the international classification sys-te ms and presents some of their main NWFPs. Each product group is fully described in the annex-es, which provide information on where it is situated in the existing international classifications, as well as production and international trade data sources. The intention of this paper is not to reinvent a statistical system of NWFPs, but rather to provide information on NWFPs in the existing national/international statistical systems so that users can compile national/regional/international statist ics on NWFPs according to their assessment needs. This report does not provide an exhaustive listing and description of all NWFPs, but does show some of the main products. Nevertheless, this document, the first among a series, provides a pic-ture, based on available data, which can be a starting point for improving statistics on NWFPs.
