How we calculate
Transparent about the formula, the data source and the accuracy bounds.
Data
The basis is the VMD State Forest Register: one row per stand (nogabals) with species (s10), age (a10), basal area (g), height (h) and diameter (d). The dump is refreshed quarterly; the current release is shown on the market pages.
Timber volume
Growing stock per stand is area Ć basal area Ć height Ć form factor: nog_plat Ć g10 Ć h10 Ć form factor (0.40ā0.45 depending on species). This is the standard mensuration estimate of standing volume.
Price
We apply indicative standing-timber prices by species and diameter grade (LVM/CSB) to the volume. A real stand does not yield 100% sawlogs but a mix: part goes to sawlogs at the grade price, the rest to pulp and firewood. So the estimate blends the grade and pulp price by diameter rather than taking the top grade for the whole volume. Around the result sits a Ā±25% band.
Maturity and felling
A stand counts as ready for main felling by age (galvenÄs cirtes vecums, Forest Law) OR by mean diameter (galvenÄ cirte pÄc caurmÄra) ā for pine, spruce and birch. So a thick stand that has not yet reached rotation age is flagged mature too.
Limits of use
This is a first-pass screening tool, not a valuer's opinion. The final price depends on the actual assortment, logistics and deal format. Always check against the VMD record ā how to read it is covered on the blog.
