Stratified

A visual companion for iNaturalist observations.

Stratified is a free web app for exploring iNaturalist data. Search iNaturalist by place, project or observer, or load a CSV export, and explore your observations as:

• Phenology wheels: the seasonal timing of flowering, fruiting and activity, compared with documented phenology from Phenobase
• Interaction networks: plant–pollinator and host-plant relationships, with published records from GloBI
• Maps with USDA soils, FEMA flood zones, EPA ecoregions and project boundaries
• Timelines and composition charts
• Print-ready exports as PDF, SVG, PNG, JPG or TIFF

It runs right in your browser: there is nothing to install, and a CSV you load stays on your computer.

Guides: how to export an iNaturalist CSV, what is a phenology wheel? and plant–pollinator interaction networks.
