Health observations build a dated record of pests, diseases and damage — incidence (share of trees affected) and severity by agent — for management, certification monitoring and biosecurity. The method is provisional: its lists and severity scales are working defaults.
Record in the field
- Choose the agent from the chips (or Other with a note).
- Severity, trees affected and trees assessed — the app checks that affected is not more than assessed.
- Host species, notes and a photo. Record observations at plots, stops or stand-wide.

The headline counts agents recorded and the worst severity; each agent’s incidence (% of trees affected) is shown with its status, and the chart compares agents. Photos taken on observations appear in Records & photos by date.
Lists of notifiable organisms change. If you suspect one, report it to the plant-health authority. The app records your observation; it does not notify anyone.
- Republic of Ireland: DAFM (Forest Service plant health).
- Northern Ireland: DAERA (Forest Service and plant health inspection).
- England and Wales: the Forestry Commission, with APHA; in Wales also Natural Resources Wales.
- Scotland: Scottish Forestry, with SASA for plant health.
- Elsewhere in Europe: your national plant protection organisation (the EU’s priority pests are listed under Regulation (EU) 2016/2031; Switzerland has its own list). The agent chips are working defaults from Irish and British practice — use Other with a note for anything else.
- No diagnosis from photos (decided against).
- No alerts to authorities or neighbours.
