This book aims at presenting the estimation methods used in the first cycle of the National Forest Inventory in Romania. Romania is the twelfth largest country in Europe, and its forest vegetation area is larger than that of Austria and Switzerland together. Yet the last forest inventory in Romania was made in 1984 and based on forest management plans, not on specific sampling and measurements.

The expectations from the inventory were therefore very high and diverse. Like any other modern inventory, RO-NFI was designed to be a multi-purpose inventory which would deliver quantitative data to the ministry and forest administrations, but also to provide the data required for the periodical reporting such as the greenhouse gas reporting. While it started from scratch, the National Forest Inventory has integrated the most recent sampling methods used in countries with similar forest conditions, such as Germany, Austria and Switzerland. The book presents the sampling methods and conclude on the effects of the estimation method on the national-level growing stock, which brings relevant information for professionals from the field, but also for policy-desion makers interested in the use of national forest inventories for reporting on forest carbon emissions and storage.

“The increased recognition of the functions and ecosystem services provided by forests underlines the need for reliable and up-to-date information on forests. Producing quantitative, diversified, and trustable information on forest states and dynamics is the aim of the National Forest Inventories. Their methods are very specific, complex, and deserve a complete presentation as endeavoured in this book for the Romanian Forest Inventory. This inventory, one of the last implemented in Europe, had to cope with the challenging context of the Carpathian forests. The development of the sampling design and estimation methods is built on the experience accumulated by older inventories and represents a fruitful collaboration coordinated by the European National Forest Inventory Network (ENFIN). The detailed information on the sampling and the estimation methods provided by this book offers a deep insight on the statistical background of forest inventories and their implementation. It constitutes a solid basis for understanding the principles of forest survey. This book is addressed to a large audience: from inventory specialists to researchers who desire to gain insights on the methods used in forest surveys.” -Dr. Klemens Schadauer, Debuty Director of BFW, ENFIN Chair
