Phenology Tagger

Phenology Tagger is a browser-based tool for iNaturalist users who need to review plant observations and record plant life-cycle information.

What it does

The app presents matching iNaturalist observations one at a time so you can add a phenology annotation. The available categories include flowering, fruiting, budding, and no evidence of flowering.

Who it is for

It is intended for naturalists, researchers, educators, and citizen scientists who use iNaturalist observations to document seasonal changes in plants.

How it works

Connect with a personal iNaturalist API token.
Choose the observation scope and location filters.
Review each plant observation and select its phenology status.
Save the annotation back to iNaturalist or skip the observation.

JavaScript is required for the interactive tagger. Your personal token is used in the browser to communicate with iNaturalist and is not sent to this app's server.
