To implement the Forest Inventory in the Amazon biome to produce information on forest resources, carbon stocks and how populations in the region use their territory


All people and institutions that use information produced by the Amazon Forest Inventory

Territorial scope

Amazon biome



A national forest inventory covers the entire country and is carried out periodically through sampling techniques, fostering on-going monitoring of forest resources. It also fosters improved management of these resources and collection of more information to help define forest policy as well as plans for use and conservation.

The only edition of the forest inventory at a nation-wide level in Brazil dates back to the 1980s and was aimed at producing information on timber stocks in natural and planted forests, that is, it was mainly aimed at timber production.

Some regional inventories were also carried out to meet specific demands for information and help colonization or planning programs. Nevertheless, no nation-wide system was prepared since 1983.


Besides aiming to measure timber stocks, carrying out the National Forest Inventory (IFN) seeks to know what the stocks of biomass and carbon are, biodiversity, the forest’s vitality and health, in addition to the standard of living of the populations that live in the forest or near them.

The variables that are collected in this in this edition of the NFI are: biophysical, to verify the Forest dynamics; socio-environmental, to check the importance of forests to the population that live there, in surrounding areas, or the relevance of exploring resources; and administrative, which will be used to monitor field work.

In addition to the biophysical data, collecting socio-environmental variables is aimed at: accompanying the use and the perception of people over time in relation to forest resources; improving and strengthening the circumstances for sustainable use of forests; assessing the effectiveness of implementing the public policies in this sector; helping formulate and adjust norms and regulations for exploring and conserving forest resources; identifying research demands, new uses of products and services and strategies to add value to the sustainable use of forests.

This project aims to implement the NFI in the entire Amazon Biome, therefore, covering an area of 419,694,300 hectares, which represents more than 40% of the national territory.


This project falls under the “Sustainable Production” (1), "Monitoring and Control" (2), "Land-use Planning" (3) and  "Science, Innovation and Economic Instruments" components of the logical framework of the Amazon Fund.

The National Forest Inventory advanced in the execution of the collection of biophysical and socio-environmental data in the bid lots, concluding 2,334 sampling points.

Botanical samples were collected from 21,670 plants, 7,505 soil samples and 5,994 socio-environmental interviews were conducted with rural residents around the sampling points.

With regard to institutional articulations, the partnerships listed below were established. All partnerships are formalized through Technical Cooperation Agreements (TCAs), and some of these agreements have concluded Decentralized Implementation Terms (DITs).

  • Embrapa Amazônia Oriental (CPATU) and the National Amazon Research Institute (INPA/Manaus-AM) with the objective of carrying out botanical identification activities and soil sample analysis, as well as the construction of a soil and herbarium laboratory;
  • Universidade Federal do Amazonas (UFAM) and the Universidade Federal do Acre (UFAC) for the construction of forest inventory and measurement laboratories and research in allometry;
  • Universidade Federal Rural da Amazônia (UFRA), the Universidade do Estado de Mato Grosso (UNEMAT), the Universidade Federal de Rondônia (UNIR) and Embrapa Florestas. 

It is also worth mentioning the realization of:

  • Technical meetings on the process of collaboration and harmonization of National Forest Inventories in the Amazon and Mesoamerica at the headquarters of the Center for Research and Higher Education in Tropical Agriculture (CATIE), in Costa Rica;
  • Technical visit for agreement with the government of Amapá;
  • Negotiation with the National Council for Scientific and Technological Development (CNPq) to grant scholarships to taxonomists to work on the identification of IFN botanical samples in the Amazon;
  • Meetings of the Public Forest Management Commission (CGFLOP), an advisory body of the Brazilian Forest Service.

In order to strengthen management capacities in the implementation and establish a research program for IFN-Bioma Amazônia, the following were carried out: a mission to monitor and evaluate the work of botanical collections; a review of the IFN field manual; preparation of the IFN Field Data Collection Quality Assessment and Control Manual; development of a non-functional prototype application for IFN data collection; and the creation of the IFN Reporting Server, in which reports are made available that subsidize quality control and data analysis activities, as well as management reports useful for project coordination. 

Improvements were also made to IFN's information system in order to make it more functional and aligned with the process flow and field forms. The system was linked to the List of Species of the Flora of Brazil, made available by the Instituto de Pesquisas Jardim Botânico do Rio de Janeiro (JBRJ), in order to provide taxonomist consultants allocated in herbaria with always updated species data. Eight training sessions were carried out for its use, with 36 trained people (13 typists from the companies responsible for the survey, 16 taxonomists and 7 servers and consultants of the SFB). 

Training events were held for the various teams involved in the project; as well as IFN control and quality missions in Amazonian states. 

In the communication, the page of the IFN Amazon Fund was restructured, its communication plan was detailed and materials were prepared to disseminate the project during the fieldwork.
