Plot basics
Plot ID, plot name, survey date, site or stand name, observer, and plot notes.
Forestry
Plot Survey Logbook (Species, DBH, Height, Health, Regeneration)
Record plot-by-plot species, DBH, height, health, and regeneration, then export CSV.
Not a general notebook. Focused on plot surveys so the UI stays simple.

What to record
Observation rows
Species, DBH, height, health, regeneration, and observation notes for each tree.
Browser storage
Browser storage keeps your draft and saved plots on the device.
CSV export
One row per observation with English column names.
How to use
- Add a plot ID, survey date, and any site or observer details.
- Add observation rows and fill species, DBH, height, health, and regeneration.
- Save the plot, or duplicate it when the next plot shares the same setup.
- Review saved plots and export the needed rows to CSV.
Examples
Standard three-tree plot
Input
plot_id=P-12A, survey_date=2026-03-26, species=Quercus serrata, dbh=28.4 cm, height=18.1 m, health=healthy, regeneration=sparse
Output
Three CSV rows are exported, and plot_id is repeated on each row.
Imperial-unit plot
Input
plot_id=T-07, species=Pinus taeda, dbh=11.2 in, height=54 ft, health=moderate_damage, regeneration=good
Output
The CSV includes unit columns, which makes downstream processing less likely to misread the units.
Frequently asked questions
Can I use this tool offline?
Yes. Data stays in browser storage on your device, so you can keep recording even without a connection.
Are CSV column names translated?
No. The CSV uses a fixed English schema, and only the UI is translated.
Can I enter species names in Japanese or English?
Yes. Species is free text, so you can write the form used in the field.
Can I mix DBH and height units in one plot?
It is not recommended. Keeping one unit per plot makes CSV processing easier later.
Can I move the data to another device?
Yes. Export CSV and move that file. Browser storage itself stays on the device.
Can I record maps or coordinates here?
Not in this version. The tool stays focused on the minimum needed for plot records.
Glossary
plot
The survey unit. This tool treats it as plot_id in CSV export.
DBH
Diameter at breast height, a standard measure of tree stem thickness.
regeneration
A record of how well the next generation of trees is expected to establish.
observation row
One tree or one observation recorded as one row.
Browser storage
The browser's persistent storage layer. It works without a server.
Notes
- This tool is for recording, not for volume, growth, or health diagnosis calculations.
- CSV column names are fixed in English. Keep display language and export language separate.
- Storage lives on the device. Clearing the browser site data will remove the records.
- If you mix units inside one plot, make the unit choice explicit in later processing.
