Bulgaria: Forest area (sq. km)

Key figures

What the numbers say

In 2025, Bulgaria's forest area (sq. km) rose 0.3% on 2024 (from 39,464 to 39,590).

Across the 30 yearly changes before that (1995 to 2024), the average change was +0.6% and a typical year strayed about 0.4% from that (the standard deviation). This year's change was 0.7 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 1.1% in 2001. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 the straight-line trend is upward, about 126 a year. A straight line explains 100% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 39,984 for 2028. We show this only because the same method, fitted on earlier years, predicted 2023 to 2025 better than "no change" would have: its average miss was 73.2, against 252 for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

How it compares

In 2025, Bulgaria had the 75th highest value of the 209 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

What this measures

Forest area is land 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: The Food and Agricultural Organization (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.

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