Guam: Forest area (% of land area)

Key figures

What the numbers say

This year's change was 0.4 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 1.59 percentage points in 2012 and the biggest yearly fall was 0.1 percentage points in 2023. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 the straight-line trend is downward, about 0.00938 percentage points a year. A straight line explains 48% of the movement over 10 observed years.

What this measures

Forest area (% of land area) is the share of total land area that is under natural or planted stands of trees of at least 5 meters in situ, whether productive or not, and excludes tree stands in agricultural production systems (for example, in fruit plantations and agroforestry systems) and trees in urban parks and gardens.

Limitations: FAO has been collecting and analyzing data on forest area since 1946. This is done at intervals of 5-10 years as part of the Global Forest Resources Assessment (FRA). FAO reports data for 229 countries and territories; for the remaining 56 small island states and territories where no information is provided, a report is prepared by FAO using existing information and a literature search. The data are aggregated at sub-regional, regional and global levels by the FRA team at FAO, and estimates are produced by straight summation. The lag between the reference year and the actual production of data series as well as the frequency of data production varies between countries.

Regional and income-group figures are computed by the World Bank as a weighted average.
