Weekbook evidence ledger

The weekbook separates personal field notes from public occurrence data. This page records exactly what is stored, queried, classified, and emphasized.

Occurrence boundary

What “every local species” means.

Geography

A fixed rectangle covering the San Antonio–Schertz corridor: southwest 29.20, −98.85 to northeast 29.80, −98.10. It is deliberately regional and does not disclose a home address.

Record quality

The species explorer requests iNaturalist research-grade species counts. Community identifications can change, and absence from the list is not evidence of true absence.

Bee rule

A species is treated as a bee when its iNaturalist taxonomic ancestry includes Anthophila (taxon 630955).

Wasp rule

The starting group is Apocrita (124417). Ant descendants (Formicidae, 47336) and bees are excluded; the remaining recorded species are labeled wasps. This practical umbrella includes social, solitary, parasitoid, gall, and other wasp lineages.

Completeness boundary

“Every” means every species returned by that query—not every species scientifically possible in the region. Tiny parasitoids, difficult groups, private-land taxa, poorly photographed insects, and species without research-grade records are underrepresented.

Emphasis rule

Why some names are bold.

For the selected month (or all year), the page sorts visible records by iNaturalist observation count and bolds the first 12. “Most likely” therefore means most frequently recorded in this source and geography. It is not a population estimate, probability forecast, safety judgment, or guarantee. Observation effort, identifiability, body size, season, camera access, and enthusiasm all affect counts.

Private-by-default architecture

Your field records do not leave the browser.

Local database

Weekly checklists, text, and compressed web copies of photographs are stored in IndexedDB under this site’s origin. No application server receives them.

Photo handling

Supported images are redrawn into a canvas, resized to a maximum 1600 pixels on the long edge, and stored as JPEG. That process strips EXIF metadata, including embedded GPS, from the saved copy.

Backups

A JSON export includes images as data URLs. CSV export omits image content. A browser reset, site-data cleanup, or device loss can erase records unless a JSON backup exists.

Public data request

The page contacts api.inaturalist.org to retrieve regional species counts and monthly histograms. It sends the public regional bounding box and selected month—not personal notes, photos, or precise observation locations.
