Keep Herp Calendar free
Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.
How the data is built
- Records. 3.68 million research-grade iNaturalist reptile and amphibian records, downloaded through GBIF (doi:10.15468/dl.5nhud6). No museum specimens.
- Places. Every record is placed in its real US Level III ecoregion and inside its state line. States are counted on their own, never added up from ecoregions.
- Seasons. Each month's count is divided by all iNaturalist records that month in that area (effort data), then smoothed with the months on either side. Peak is at least half of the best month; shoulder is at least 15%. A month needs 10 or more records to count, and a species needs 75 or more records to show in an area.
- Protected species. 147 species are left off entirely: anything federally listed, IUCN Vulnerable or worse, or NatureServe G1 to G3. Species ranked imperiled in a state (NatureServe S1 or S2, or on a state list) are hidden in that state and every ecoregion touching it.
- Text. Species descriptions are word-for-word quotes from Wikipedia (CC BY-SA) and Animal Diversity Web, each linked to its source. Ecoregion and state summaries are written from the counts on each page.
- Photos. iNaturalist photos under CC0, CC BY or CC BY-SA only, credited on every photo.
