Does observer's account ever count as evidence?

[AdamWargon]

From a thread called “What is evidence?”

@bouteloua

Photos and sound files of the organism itself, or sign of that organism, like tracks/scat/nests/galls are considered evidence on iNaturalist. What about other things, like:

• an illustration
• an attached description or comment by the observer describing a sound or feature not depicted in the photo
• spectrogram of a bat call
• a link to or observation field with DNA sampling info
