Height-based single tree
Енгізу
DBH 35 cm / height 18 m / wood density 0.62 g/cm3 / height-based preset
Нәтиже
AGB ≈ 732.08 kg, carbon ≈ 344.08 kg C, CO2e ≈ 1,261.61 kg
Field estimate / forestry
Forest Biomass and Carbon Estimator
Estimate above-ground biomass, carbon, and CO2e from DBH, tree height, wood density, and species group in a browser-only workflow.
Start from built-in reference equations, save your own coefficient sets, and fall back to DBH-only estimates when field data are incomplete.
Built-in equations plus one custom preset you can save
Switch to DBH + density or DBH-only fallback when height is missing
Optional BGB with root/shoot ratio defaults

Қолдану әдісі
- Choose the estimate mode, species group, and a preset, then confirm whether the built-in values match your local workflow.
- Enter DBH first, then add tree height and wood density when the selected mode needs them.
- Turn on root biomass if you want BGB, and switch the carbon fraction between preset, species-specific, or custom values as needed.
- Review the result, then copy it, share the URL, or export JSON and CSV for later reuse.

Three trees: 24 cm / 14 m / 0.58, 26 cm / 15 m / 0.59, 28 cm / 16 m / 0.60, plot area 0.05 ha
Нәтиже
Total AGB ≈ 992.62 kg, carbon ≈ 466.53 kg C, CO2e ≈ 1,710.62 kg, or 19.85 t/ha
Formulas
All inputs are normalized to cm, m, g/cm3, kg, and t before the selected equation runs.
- AGB = a × (rho × D^2 × H)^b
- AGB = a × rho^c × D^b
- AGB = a × D^b
- BGB = AGB × root/shoot ratio
- Carbon = total biomass × carbon fraction
- CO2e = carbon × 44 / 12
Glossary
DBH
Diameter at breast height, measured at breast height or your local standard.
AGB
Above-ground biomass. This page reports it as the main biomass result.
BGB
Below-ground biomass. It is optional and uses a root/shoot ratio when enabled.
Wood density
Basic wood density or specific gravity used to tune the model.
Carbon fraction
The share of biomass assumed to be carbon. The default in this tool is 0.47.
Root/shoot ratio
A multiplier used to estimate BGB from AGB when root biomass is turned on.
CO2e
Carbon dioxide equivalent. Carbon is multiplied by 44/12 to convert to CO2e.
Frequently asked questions
Can I use this for formal carbon reporting?
Жоқ. Бұл бет сертификатталған есеп беру немесе аудит жұмыстары үшін емес, далалық бағалаулар мен жылдам жоспарлауға арналған.
What if tree height is missing?
Switch to the DBH + density or DBH-only preset. The page keeps the calculation moving when height is not available.
Can I type decimal commas?
Иә. Парақта ондық үтірлер де, ондық нүктелер де, сондай-ақ қарапайым өлшем бірліктерінің жалғаулары да қабылданады.
Can I save my own coefficients?
Иә. Осы браузерде жеке баптауды сақтаңыз, содан кейін портативті көшірме қажет болса, оны JSON форматында экспорттаңыз.
Does the page send my data to a server?
Жоқ. Енгізілген деректер, алдын ала орнатулар және нәтижелер оларды анық көшірмесеңіз немесе бөліспесеңіз, браузерде қалады.
Маңызды ескертпелер
- Built-in equations are reference values only. Replace them with approved local coefficients when you have them.
- Wood density, carbon fraction, and root/shoot ratio can vary by species, site, and data source.
- Root biomass is optional. Leave it off if you only need AGB.
- Per-hectare values depend on the plot area you enter. The page does not infer stand area for you.
- Avoid putting private stand names into share URLs if they should not be public.
