Abstract

The area of land covered by forest and trees is an important indicator of environmental condition. This study presents and analyses results from the Global Forest Resources Assessment 2015 (FRA 2015) of the Food and Agriculture Organization of the United Nations. FRA 2015 was based on responses to surveys by individual countries using a common reporting framework, agreed definitions and reporting standards. Results indicated that total forest area declined by 3%, from 4128 M ha in 1990 to 3999 M ha in 2015. The annual rate of net forest loss halved from 7.3 M ha y−1 in the 1990s to 3.3 M ha y−1 between 2010 and 2015. Natural forest area declined from 3961 M ha to 3721 M ha between 1990 and 2015, while planted forest (including rubber plantations) increased from 168 M ha to 278 M ha. From 2010 to 2015, tropical forest area declined at a rate of 5.5 M ha y−1 – only 58% of the rate in the 1990s – while temperate forest area expanded at a rate of 2.2 M ha y−1. Boreal and sub-tropical forest areas showed little net change. Forest area expanded in Europe, North America, the Caribbean, East Asia, and Western-Central Asia, but declined in Central America, South America, South and Southeast Asia and all three regions in Africa. Analysis indicates that, between 1990 and 2015, 13 tropical countries may have either passed through their forest transitions from net forest loss to net forest expansion, or continued along the path of forest expansion that follows these transitions. Comparing FRA 2015 statistics with the findings of global and pan-tropical remote-sensing forest area surveys was challenging, due to differences in assessment periods, the definitions of forest and remote sensing methods. More investment in national and global forest monitoring is needed to provide better support for international initiatives to increase sustainable forest management and reduce forest loss, particularly in tropical countries.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The increased extent of temperate and boreal forests has been accompanied by increased fragmentation and changes in function, such as carbon storage.

    “and the increased extent of temperate and boreal forests ( 28 ) has been accompanied by increased fragmentation and changes in function [such as carbon storage ( 29 )].”

    From Pervasive human-driven decline of life on Earth points to the need for transformative change (2019) · cites this paper as [28]

    The citation to this source (28) is attached to the increased extent of temperate and boreal forests, not to the later statements about fragmentation and carbon storage. Section 3.3 reports a 67 M ha increase in temperate forest from 1990 to 2015, but says boreal forest showed little change; it does not support a comparable increase in both domains. (LLM, conf=0.88)

  • In relative terms, the forests of Central Africa, especially in the Democratic Republic of Congo and the Republic of Congo, have been comparatively well preserved.

    “In relative terms, the forests of Central Africa, especially in the Democratic republic of Congo and the Republic of Congo have been comparatively well preserved (Hansen et al 2013, Keenan et al 2015).”

    From The impact of deforestation on rainfall in Africa: a data-driven assessment (2021) · cites this paper as Keenan et al 2015

    Section 3.1 identifies the Democratic Republic of Congo as one of the countries with the most forest area, which lends limited support to the idea that substantial forest remains there. But section 3.2 reports declining forest area in West-Central Africa, and section 3.5 lists the DRC among Africa’s largest net forest losses in 2010–2015. The cited passages do not establish that Central Africa—or the Republic of Congo in particular—was comparatively well preserved. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
