How to run a BioBlitz
A BioBlitz is a communal effort to document as many species as possible in a defined place and time—not proof that every species present was found.
Scope: Small community biodiversity events worldwide; permissions, accessibility, safeguarding, site hazards, and collecting rules are local · Last updated
Set a bounded objective
Draw the event boundary, choose start and end times, and decide whether to cover all visible life or a smaller set of habitats or taxa. A short event produces a time-bounded snapshot shaped by weather, season, search effort, and participant skills. Phrase the result as species documented during the event, not a complete inventory or an abundance estimate. [1][2][3]
Build permission and care into the plan
Obtain land-manager approval and check access, group-size, and collecting rules before announcing the event. Map accessible routes, meeting points, weather contingencies, communication, and site-specific hazards with the land manager. Observation does not imply permission to capture or remove organisms; U.S. national-park research collecting, for example, requires a permit. [1][5]
Rehearse the data workflow
Configure the project filters for the exact place and dates, then test an observation and its upload from the site. Train participants to make separate, verifiable records with accurate time and location, and plan for weak connectivity. Recruit local naturalists and taxon specialists to review records after the field session rather than pressuring beginners into premature species identifications. [2][4]
Close the loop after the event
Allow time for uploads, combine duplicate views of the same encounter when the platform requires it, and keep uncertain identifications visibly unresolved. Publish the boundary, dates, participant and effort notes, methods, species total, and known gaps. Share results with participants and the land manager, and retain an export or stable project link so later corrections remain traceable. [1][2][3][4]
