A BioBlitz is a race against time to create a snapshot of the variety of life in a specific location. Wildlife experts and citizen scientists find and identify as many species of plants, animals and fungi as possible in the area within a set amount of time.

Help photograph, document and celebrate the flora, fauna and fungi in our towns. Taking observations of wildlife helps advance science. According to National Geographic, "High quality data uploaded to iNaturalist become part of the Global Biodiversity Information Facility, an open source database used by scientists and policy makers around the world."

The sixth annual BioBlitz “Nature of Acton and Boxborough 2026” runs from April 24 through May 4. Find our more here: https://www.inaturalist.org/projects/nature-of-acton-and-boxborough-2026.

According to The Acton Exchange, “Last year the BioBlitz had 23 Acton and Boxborough observers who saw 404 species. Let’s beat those marks!”
