Explore the potential range of every California wild plant

Calflora's Plant Range models estimate where a species can occur based on climate, watershed, and thousands of verified plant observations. You can download these range models for use in GIS and other mapping software.

Every California wild plant in Calflora has its own Plant Range page. Try it yourself:


  1. Search for any California wild plant
  2. Open its Calflora taxon page
  3. Click Plant Range
  4. Sign in to download the climate or watershed model

How does Calflora estimate plant ranges?

Calflora combines millions of plant observations from hundreds of data sources, including Consortium of California Herbaria specimens, iNaturalist observations, Calflora records, and many partner organizations.


For each documented plant occurrence, Calflora analyzes elevation, precipitation, seasonal temperatures, hardiness zone, growing season, moisture patterns, watershed, and other environmental conditions within the relevant California ecoregion. Our model identifies locations with similar conditions to estimate current suitable habitat and produce a potential range map.


These models represent current suitable habitat; they do not predict the effects of climate change, fire, or future plant distributions. Calflora Plant Range models are a powerful way to explore where current suitable habitat may exist.
