REVIEWING A TREE SPREADSHEET BEFORE REUSE Clean a working copy without losing the meaning of the source record. Identify inconsistent IDs, units, dates and evidence references, and keep a log of approved changes rather than silently normalising everything. Project/site: Prepared by/date: Version: Source version Identify the unmodified original schedule. Notes: Issue type Describe the inconsistency found in a column. Notes: Affected records List the tree IDs or rows involved. Notes: Approved change State how the problem will be resolved. Notes: Review evidence Keep source notes and the check result. Notes: CHECKS [ ] Treat blanks differently from confirmed zero values. [ ] Check text identifiers and date interpretation before saving a CSV. [ ] Review affected exports after an approved correction. Outstanding questions: Source references: Review and next action: Scope: Cleaning does not validate professional conclusions or create missing observations; unresolved values remain explicit.
