For centuries they have provided a whole analyzing the extent and structure of forests in comparison range of positive impacts on human welfare and are still to NFI results. Policies, built on insufficient data about an important asset for the Ukrainian people. Ukrainian forests might lead to undesired forest policy decision making. As these positive aspects depend on the extent, quality and structure of forests, sufficient knowledge about forests This brochure presents the approach and major outcomes is essential to meet the societal needs in an appropriate from these regional forest inventories. It demonstrates manner. Moreover, the current controversial discussion the usefulness of the methodology of National Forest about timber use requires a transparent approach towards Inventories. Further, Ukrainian inventory specialists have reliable information about the state of forests, protection, now gained experiences on how to implement a NFI harvesting and regeneration measures as well as the and are able to carry out a forest inventory for the whole expected development of forests in the future. country. International experiences in all EU countries, USA, A new powerful impetus for the development of a Canada, Australia, China, India, Japan and many other National Forest Inventory was given by the Decree of countries indicate that National Forest Inventories (NFI) the President of Ukraine No. 381/2017 “On Additional are an appropriate and effective tool for gathering such Measures for the Development of Forestry, Rational Use information and providing it in a transparent way as a of Nature and Preservation of Natural Reserve Funds” base for forest policy decision making. issued on November 21, 2017. The President ordered the Cabinet of Ministers of Ukraine “to ensure a national During 2008-2015 the Ukrainian government supported inventory of the forest fund of Ukraine taking into account regional forest inventories in Sumy and Ivano-Frankivsk best international practice”. To execute the President’s oblasts across an area of about 1 Mill. ha, using statistical Decree the State Forest Resource Agency approved a Plan methods of NFI, characterized by reliable accuracy. The of Measures in 2018 for Preparation of a National Forest outcomes from these regional inventories revealed Inventory. 2 NATIONAL FOREST INVENTORY FORESTS: Represent a less influenced Are the base for recreation ecosystem, when comparing of people and biodiversity them to urban and of flora and fauna agriculture land use Absorb CO2 Provide the resource from the atmosphere and for forestry, timber industry thus have a positive impact and wood exports on climate change Offer jobs and incomes for thousands of families in rural areas How forest policy contributes to public acceptance of forest use 3 Forest ecosystem - what is it in reality? Photo: Oleg Malov nce visiting the forest, we all seem to understand also permanently or temporarily not covered by forest O what a forest is. vegetation, due to the heterogeneity of forest natural systems, protection measures, planting, harvesting or The Forest Code of Ukraine defines “forest” as a type of natural disturbances, etc. natural complex (ecosystem), which combines mainly woody and shrub vegetation with appropriate soils, For the Ukrainian NFI it is proposed to use a comprehensive herbal vegetation, animal world, microorganisms and definition of forest as a land parcel with an area of not less other natural components that are interconnected in their than 0.1 ha and more than 20 m wide, which is covered development affecting each other and the environment. with woody and shrub vegetation, with crowns covering not less than 30% of the area of the parcel, and height at Forest areas may be covered with forest vegetation, and maturity of at least 5 m. 4 NATIONAL FOREST INVENTORY NFI - the statistical view on forests enerally, there are two major data sources on forests in of sample plots, presenting inventory sites. These plots are G Ukraine. distributed over the territory in regular squares. Thus, NFI is more efficient and provides data simultaneously for the whole Forest management is traditionally based on data, provided by country at one time. NFI´s are a relatively inexpensive way to forest planning over a 10 years period. This approach is focused obtain reliable estimates for the whole country, regions or mainly on the commercial use of forest and related supporting natural areas. Each analyzed parameter is linked to a confidence (e.g. protection and regeneration) measures. The so-called interval. forest planning data is collected from all forest stands in a given enterprise, thus data gathering by this means is a quite The accuracy of estimates of analyzed characteristics depends expensive process. Further, data for a particular enterprise is on the accepted pattern of probability sampling. Therefore, the assembled during the given year of implementation of the estimations of national inventory are carried out with given forest planning project. Combining data of all enterprises into boundaries of accuracy. The sampling of plots is designed so a country data set will provide limited results, as the data stems that the statistical error of the estimation of the total growing from various years with a time lag of at least 10 years. Due to stock for all forests will not exceed 3%. With each new inventory, the lack of data on the accuracy of estimates for individual the accuracy of data in the statistical and forestry terms will forest stands, the boundaries of errors for consolidated forest increase significantly. information data cannot be established. In the following graphs distribution of plots in forest area is In comparison to this, the NFI is designed to obtain information given for the two oblasts where regional forest inventory was on all forests of Ukraine as a whole, based on a small number implemented earlier. Forest cover Forest cover of Sumy oblast – 17.8% of Ivano-Frankivsk oblast – 41.0% How forest policy contributes to public acceptance of forest use 5 NFI – first steps in Ukraine he technological process of forest inventory that cycle on every forest plot. Re-measurement on the forest plots T were carried out in Sumy and Ivano-Frankivsk oblasts was implemented during 2014-2015. included three stages: Analyzed characteristics
