Data Collection

Templates

As with any tree survey or inspection, QTRA data can be collected using paper forms, hand held tablet computers and PDAs, or by dictation and transcription to spreadsheets.

We provide sample schedules for the survey of groups or compartments, multiple individual trees, or the detailed investigation of a specific individual.

These templates can be used for manual data entry or adapted to download electronically from data collection devices.
