How much production forest exists globally?

An estimated 1.15 billion hectares (Bha) of forest are designated primarily for production, equivalent to roughly 30 percent of global forest area.FAO 2020, http://www.fao.org/3/ca9825en/CA9825EN.pdf . This 2020 estimate reflects a slight decrease of about 50 Mha since 2015.FAO 2016, http://www.fao.org/3/a-i4793e.pdf . Although most production forests are natural forests, planted forests and tree plantations increased in area by 75 percent (167–290 Mha) between 1990 and 2020 and are expected to play a growing role in meeting rising global demand for wood products.FAO 2020, http://www.fao.org/3/ca9825en/CA9825EN.pdf . As of 2020, planted forests and tree plantations account for 7 percent of global forest area (up from 4 percent in 1990).FAO Forestry database, http://www.fao.org/forestry/en/ . These estimates are published by the FAO and based on national-scale statistical data rather than geospatial data.

Where are the world’s production forests?

No publicly available and globally comprehensive map of production forests currently exists. The available map approximates the location of production forests based on a model that identifies areas in which large-scale forestry operations are the dominant cause of tree cover loss .Curtis et. al. 2018, https://science.sciencemag.org/content/361/6407/1108/tab-figures-data . Production forests appear extensively in the temperate and boreal forests of North America, Europe, Russia, China, southern Brazil, Chile, South Africa, and Australia. The model largely fails to identify production forests known to exist in the tropics for reasons described below.

Current Models of Production Forests

Forest areas in which large-scale wood harvesting operations are the dominant cause of tree cover loss

Production forests

The model used to create this map analyzes 30-by-30-meter (m) pixel tree cover change dataBased on the Hansen et al. (2013) Global Forest Change data set, https://earthenginepartners.appspot.com/science-2013-global-forest/download_v1.7.html . and other data inputs to identify the dominant driver of tree cover loss within a 10-by-10-kilometer (km) grid cell. Cyclical patterns of tree cover loss and gain in the same grid cell are considered a likely indicator of forestry activities, in which wood harvesting is followed by forest regeneration and/or tree planting. Due to the spatial resolution of the model and underlying tree cover change data,The model identifies the dominant driver of tree cover loss within a 10-by-10 km grid cell, interpreted from underlying tree cover change data at 30-by-30 m resolution. the map is most likely to capture tree cover in which industrial roundwood is being harvested at large scales, whether through rotational harvesting of plantations, stand-level clear-cuts of natural or seminatural forests, or mechanized selective logging. Nonindustrial or highly selective forms of harvesting are less likely to be visible within 30-meter resolution Landsat satellite imagery and are therefore less likely to be reflected in the model results. Nonindustrial and selective harvesting can include collecting fuelwood for subsistence purposes, some forms of thinning to reduce fire risk, and highly selective felling of individual trees (e.g., canoe trees) where the surrounding forest is left intact.

Where are the world’s tree plantations?

Intensively managed tree plantations are typically not considered a “forest” due to their limited species composition and row-like spacing, but they play a critical role in meeting global demand for wood products. A 2018 studyHarris et al. 2019, https://www.wri.org/publication/planted-trees . aggregates maps of tree plantations from a variety of sources and time periods; the maps are estimated to capture roughly 75 percent (173 Mha) of tree plantations worldwide. Based on this map, four countries account for half of all tree plantation area: the United States, Brazil, China, and Japan. Other than Japan, these countries are among the world’s top five producers of industrial roundwood. Key roundwood-producing countries that are missing from this data set include Canada and Russia (ranked second and third, respectively, for industrial roundwood production globally), which rely more on natural and seminatural forests for wood production rather than intensively managed tree plantations.

Limitations and Future Prospects

Comprehensive and complete data showing the location of production forests worldwide are currently lacking. Without such data, it is difficult to systematically assess the extent to which such forests are being managed sustainably and the changing condition and capacity of these forests to provide essential wood products.

Mapping forest areas in which large-scale forestry operations have been classified by a model as the dominant cause of tree cover loss provides one way to approximate the location of production forests. However, this approach likely misses forests in which selective logging is the main form of wood harvesting due to the relatively coarse resolution of the model (10-by-10 km) and underlying satellite data (30-by-30 m). Efforts to use higher-resolution satellite imagery to detect tree cover change and refine driver classification models—both of which are currently under way—may allow for better approximation of production forest locations in the near future.

Public disclosure of logging concession data in countries where most production forests are publicly owned and boundary data for privately held production forests could also help fill this data gap. Forest managers and national and subnational forest agencies often hold a wealth of geospatial data on production forests, including boundaries, growing stock, species distribution, and harvest volumes, but these data tend to be highly tailored to the local context and are often not open to the public. Even if such data were to become publicly available, collecting and consolidating disparate data sets into a consistent and regularly updated global map remains a significant challenge.

Many Forest Products Are Not Captured in Official Statistics

Forests provide a wealth of timber and nontimber forest products to rural communities, most of which are not reflected in official statistics on forest production and are impossible to map at scale. As such, the forests that provide these benefits to local communities are unlikely to be captured in the maps of production forests featured in this indicator. Forest fuelwood, for example, makes up roughly half of global wood removalsFAO 2016, http://www.fao.org/3/a-i4793e.pdf . and 40 percent of global renewable energy—as much as solar, hydroelectric, and wind power combined.FAO 2018. http://www.fao.org/3/i9535en/i9535en.pdf . As forest degradation and deforestation spread, communities have to walk longer and farther to obtain wood for heating homes and cooking food. Other important nontimber forest products include fruits and nuts, vegetables, fish and game, medicinal plants, resins, and natural fibers such as rattan.
