Capture the whole organism
Include a full view and its immediate surroundings. A close-up without habitat can remove information needed to interpret it.
Photograph better field evidence
Good identification starts before you press the shutter. Gather enough views and context that a later reviewer can understand what you saw, while preserving uncertainty about the name.
A workflow you can use
Record scale and visible structure
Use a ruler or another explicit scale. For plants, note leaves and stems; for fungi, document visible cap, underside and stem without unsafe handling.
Describe the habitat
Record substrate, nearby vegetation and weather context in plain language. Approximate location can be enough for your private notes.
Keep uncertainty visible
Write tentative labels as tentative. If an identification matters, ask a qualified local expert rather than converting a guess into a confident name.
Put the idea into practice
A concrete example
Two similar-looking fungi may differ in underside structure, substrate and the base of the stem. A single top-down cap image leaves those questions unanswered, even when a model supplies a species name.
When to use the iPhone app
Fieldmark's listing describes confidence bands, genus-level fallback and guided questions for plant and fungi identification. It says the app does not certify edibility and highlights dangerous lookalikes.
Know the boundary
This notebook cannot identify a species or establish whether anything is safe to eat. Do not rely on a photograph, app or exported note to decide edibility. Avoid disturbing specimens or disclosing sensitive locations.
Plant and fungi observation notebook
A useful nature observation records more than one attractive photo. Capture location context, size, habitat and the details an identifier cannot infer from a top-down view. This notebook exports a structured observation for later review.
The checklist assesses whether you recorded the listed observations, not identification confidence. An observation with every box filled can still be insufficient for species identification.
