Present but Not Returned

Repeat-Visit Search Surveys of a Naturalists' Club Newsletter Archive

A research poster from the School of Underlying Conditions treats 120 member enquiries to a naturalists' club's digitised newsletter archive as survey sites and four volunteer searchers as repeat visits, fitting a single-season occupancy model that puts the share of enquiries the archive can answer at 0.68 against a naive 0.45. Per-searcher detection falls from 0.52 to 0.14 where a species' name has been revised since the note was written.
