Background and aims

It was almost 100 years ago when the first national forest inventory (NFI) was established in 1919. Objectives, techniques, and resources in the NFIs have evolved during this period to be able to provide answers to the society. From decision support on national, regional or local forest policy, to international reporting under the Climate Convention, or forest health monitoring, the societal requirements (and challenges) on the NFIs are getting broader.


We would like to take this unique opportunity to celebrate the first 100 years of history of the NFIs by bringing together researchers and practitioners with an interest in forest monitoring, to reflect on the passed challenges, the lessons learned, and to improve future large-scale forest and landscape inventory programs.


NFIs provide information on natural resources for informed decisions on a variety of scales. NFI data are today used for example for supporting decisions on national and regional forest policy, for international reporting under the Climate Convention, and for investment decisions of large timber processing companies. The first NFI was begun in 1919 in Norway on the backdrop of the fear of over-exploitation of timber resources. Finland, Sweden, and the USA started their NFI programs in the 1920s. Debates on acid rain in the 1980s were a trigger for initiating NFIs in central Europe. In the recent years, climate change (REDD+) was one of the main reasons for the establishment of new NFIs, especially in developing countries while most developed countries have regular NFI programs. While monitoring sustainability is still a major component, NFIs today have a much wider focus and also monitor forest health, ecological indices such as biodiversity and many other ecosystem services of landscapes in general.
