Synopsis (short abstract) This field manual contains definitions and procedures used to plan and perform a national forest inventory and assessment following the approach developed by the Forest Resources Assessment programme (FRA) of the FAO. The methodology, based on nation-wide field sampling, has already been tested and implemented in several countries since year 2000 (Costa Rica, Guatemala, Philippines, Cameroon and Lebanon). The purpose of the national forest inventory (NFI) is to assess forest resources and tree r esources outside forest and to provide new qualitative and quantitative information on the state, use, management and trends of these resources. The assessment covers a large range of biophysical and socio-economic variables and thus, provides a broad and holistic view of land use for the country as a whole. In particular, the information will be used to plan, design and implement national and international policies and strategies for sustainable use and conservation of forestry ecosystems, and to understand the relationship between resources and users of the forest and tree resources. The first part of the manual describes the adopted sampling design and the distribution and configuration of the tracts where measurements are carried out. The second part deals with the forest type/land use classification adopted to carry out the inventory. Recommendations to undertake data collection in the field are presented in the third part. In part four the field forms are described in detail. The Appendices provide some tools and methods for measuring the variables such as diameter, height, horizontal distance, a guide for the use of Global Positioning System receivers (GPS) as well as techniques and recommendations to carry out interviews and group discussions.

    This manual was prepared within the framework of a technical assistance (TA) agreement entitled “Forest Resources Inventory and Establishment of a forest reference level for REDD+ in Nigeria (UTF /NIR/066/NIR (644170)”, to support the implementation of national forest inventory (NFI) in Nigeria. An NFI is a key component of a measurement, reporting and verification (MRV) system which is a requirement of the United Nations Framework Convention on Climate Change (UNFCCC) for the national forest monitoring system to assess anthropogenic forest-related greenhouse gas emissions by sources and removals by sinks. The results of the NFI will be used to support national institutions to address issues of REDD+ and greenhouse gas (GHG) international reporting obligations. It can be also used to review the policy processes to support sustainable forest management at national level.

    An accurate inventory of forest and tree resources is essential for formulating sound strategies for forestry development. Accurate and up-to-date information on forest cover and growing stock of forests and trees are basic ingredients for planning and policy development. Tree resources outside forest areas or trees outside forests (TOF) can cover considerable areas. Traditionally, TOF were not inventoried and as a result, quantitative information about TOF is scarce. However, besides providi ng support to subsistence economies, these trees form a substantial source of raw materials for forest industries. This manual introduces several aspects of TOF inventories, to provide readers with a comprehensive overview of the tools needed to conduct an inventory. It provides insights into survey methods, describes procedures for data collection, data analysis, and formats for recording data during field surveys. Case studies from various countries are used to illustrate different inventor y methods. The emphasis is on practical and conventional methodologies.
