Concept and Legal Basis of the National Forest Inventory
Die National Forest Inventory (BWI) is a central, legally regulated procedure for the systematic and large-scale recording of forest areas and forestry resources in Germany. It serves the statistical collection, analysis, and documentation of the state, structure, and development of forests at the federal level. The National Forest Inventory forms an essential data basis for forestry, ecological, and forest policy decisions and is closely linked to various legal regulations—particularly the Federal Forest Act.
Legal Basis
The obligation to conduct the National Forest Inventory arises mainly from § 41 paragraphs 1–3 of the Federal Forest Act (BWaldG). The Federal Forest Act obliges the Federal Republic of Germany to regularly conduct surveys on the extent and condition of forests and to provide this data. Supplementary legal bases can be found in ordinances and administrative guidelines that specify details for implementation. The execution is entrusted to the Federal Agency for Agriculture and Food (BLE) and the Thünen Institute, which act on behalf of the Federal Ministry of Food and Agriculture (BMEL).
Objectives and Significance of the National Forest Inventory
Purposes of Data Collection
The National Forest Inventory pursues various aims:
- Sustainability: Monitoring of sustainable forestry in accordance with § 1 BWaldG.
- Reporting: Fulfillment of international reporting obligations, e.g. to the European Union or the Framework Convention on Climate Change (UNFCCC).
- Planning Certainty: Provision of reliable data for forest policy and nature conservation planning processes at both federal and state levels.
Material and Spatial Scope
The provisions of the Federal Forest Act extend to all forest areas (according to §§ 2 and 3 BWaldG) within the Federal Republic of Germany, regardless of ownership or type of use. The National Forest Inventory makes no distinction between state, communal, or private forests—all areas falling under these definitions are surveyed.
Conducting the National Forest Inventory from a Legal Perspective
Methodology and Legally Regulated Procedures
The data collection is based on standardized scientific methods, which are prescribed in subordinate legal provisions and technical guidelines (such as the National Forest Inventory Ordinance). Usually, a systematic sampling design with fixed survey points is used. The data are collected, processed, and published periodically—currently approximately every ten years (§ 41 paragraph 2 BWaldG).
Data Protection and Data Usage
In the course of the National Forest Inventory, all personal or business-specific data are subject to special data protection regulations. According to § 41 paragraph 3 BWaldG, the collected data may be used exclusively for forest statistical purposes. The disclosure of sensitive individual business information is excluded; only anonymized, aggregated results are published.
Freedom of Information and Transparency
The results of the National Forest Inventory are generally available to the public in accordance with § 41 BWaldG and the Environmental Information Act (UIG). The Federal Government is obliged to regularly publish the key results and inform the Bundestag as well as the public.
Significance of the National Forest Inventory for Law and Practice
Steering Instrument and Legal Effects
The results of the National Forest Inventory play a decisive role in shaping and implementing forest-related legal provisions at federal and state level. They influence:
- Forestry Funding Programs (§ 41a BWaldG)
- Adjustment and administration of forestry use permits and obligations
- Assessment of the legal conformity of forestry practices according to the principle of sustainability
- Implementation of international obligations in the fields of environmental and climate protection law
Legal Consequences of Non-Implementation
Failure to carry out or defective implementation of the National Forest Inventory can have significant legal and political consequences. These include in particular shortcomings in fulfilling international obligations for the protection and sustainable use of forests as well as possible violations of the Federal Forest Act.
Other Relevant Legal Provisions and Current Developments
Compatibility with European and International Standards
The National Forest Inventory interacts with European legal acts such as the European Forest Strategy, Regulation (EU) No. 691/2011 on European environmental economic accounts, and other reporting obligations under international agreements. This results in further, detailed requirements regarding the scope and methodology of data collection.
Amendments and Adaptation of Legal Foundations
With technological advances, changing societal requirements, and international obligations, the legal framework of the National Forest Inventory is subject to continuous adaptation. Amendments to the Federal Forest Act or implementing ordinances reflect current technical and legal requirements.

Frequently Asked Questions
Which legal regulations govern the implementation of the National Forest Inventory?
The implementation of the National Forest Inventory is based on a series of legal provisions, the core of which are the Federal Forest Act (BWaldG) and supplementary legal regulations. § 41a BWaldG obliges the federal government to regularly conduct a nationwide forest inventory to record forest areas and their condition. This is carried out with strict attention to data protection and the informational self-determination of forest owners, as set out in the Federal Data Protection Act (BDSG) and the respective state data protection laws. Practical implementation is detailed in administrative regulations and decrees at federal and state level, which specifically regulate tasks, methods, data processing, as well as reporting and publication obligations. In addition, the Environmental Information Act (UIG) and European requirements from Regulation (EU) No. 995/2010 (EUTR) are taken into account in data collection and usage. The legal basis ensures that the federal and state authorities obtain uniform and comparable data on the state of German forests and manage them properly and in compliance with data protection requirements.
To what extent is participation in the National Forest Inventory mandatory for private owners?
According to § 41a paragraph 5 BWaldG, private forest owners are legally required to tolerate entry and measurement of their land as part of the National Forest Inventory. This means they must permit access and measures required for the inventory; however, there is no obligation for active cooperation. This restriction serves to uphold proportionality and property protection under Article 14 of the German Basic Law (GG). Interventions in the property rights of forest owners thus only occur to the extent justified by the public interest and as determined by law. However, areas enjoying special legal protection are exempt, for example, military restricted areas or nature reserves with entry bans.
How are the collected data legally protected and who has access to them?
The data collected within the framework of the National Forest Inventory are processed in accordance with the Federal Data Protection Act (BDSG), the General Data Protection Regulation (GDPR), and, where applicable, state data protection regulations. Personal data collected in connection with privately owned forest areas may be used exclusively for inventory and forestry reporting purposes. Disclosure to third parties, especially outside the public administration, is generally prohibited unless there is an explicit legal basis. The data collected are typically aggregated and anonymized before being used for forest policy analysis or publications. Rights of access for third parties exist only within the framework of environmental information laws (UIG) and while observing the protection of legitimate business and trade secrets.
What legal provisions apply in the event of objection or refusal to provide data by forest owners?
The Federal Forest Act provides for a duty of tolerance in § 41a; refusal to allow authorized measures in the context of the National Forest Inventory constitutes an administrative offense and may be penalized with a fine according to state administrative offense laws. However, there are exceptions, for instance, where justified interests exist, such as danger to the life, health, or property of the forest owner or the protection of special legal interests. In these cases, exceptions may be individually reviewed and granted by the competent state authority. There is no general right of objection; legal remedies against individual orders of the inventory may be sought through administrative legal proceedings.
Who bears the legal responsibility for errors or damages that occur during the inventory work?
For damages arising directly in connection with the National Forest Inventory, general state liability law applies. Responsibility for the legality of the measures and any claims for damages lies with the federal government or the respective state authority conducting the work. Forest owners have a legal claim for compensation for proven damage to stands, land, or property, provided the damage was caused by the inventory activities and does not fall under general operational or life risks. The assessment and regulation of claims for damages are carried out in accordance with §§ 839 BGB, 34 GG, and relevant provisions from the respective state law.
What legal framework applies to the publication or use of the inventory data?
The publication of the results of the National Forest Inventory is governed by the principle of public access and information rights according to the Environmental Information Act (UIG) and the provisions on freedom of information (IFG). Publication is carried out in the form of aggregated data and reports to transparently present the state of forests in Germany and to serve as a decision-making basis for political, scientific, and economic actors. Further individual uses, such as for research or administrative action, are permitted under the respective legal requirements and with strict attention to data protection. Commercial use of the data is generally excluded or subject to approval unless otherwise specified. Business and trade secrets, as well as personal information, are always protected during publication.
Are there any special legal requirements for the inventory in special protected areas or where property protection is of particular concern?
Yes, there are additional legal requirements for conducting the National Forest Inventory in protected areas—for example, national parks, nature reserves, flora-fauna-habitat sites, or military restricted areas. In these areas, the inventory may only be conducted in accordance with the respective protection laws (e.g., Federal Nature Conservation Act, state nature conservation laws, special regulations for Bundeswehr properties) and the procedures established therein. Coordination with the responsible protected area authority or owner is often required, and there may be restrictions or special conditions regarding access, sample collection, or data processing. Compliance with these special legal requirements is mandatory for the legitimacy and lawfulness of inventory measures in such areas.
