BioBlitz Frequently Asked Questions

A BioBlitz is a 24-hour inventory of all living organisms in a given area. The first Save Mount Diablo BioBlitz was held 2007 on Irish Canyon. BioBlitz events are used to bring the public and the scientific community together to establish baseline data about the biodiversity of an area. It’s a great opportunity for the public to explore new areas and be involved in real science data collection. The data collected by citizen scientists is used to study how species composition in a certain area change over time.
SMD’s 2022 BioBlitz is tentatively planned for April 16 to 30. The 2022 BioBlitz will focus on the 2020 SCU Lightning Complex fire footprint, which is 393,624 acres. We are encouraging participants to visit sites that are open to the public.
Due to COVID-19, there is no specific place that we will be gathering. Instead, we are encouraging participants to visit sites with public access safely, during their own time and following county and state COVID-19 guidelines. Please check out the Burn Areas section for suggestions on places to visit.

Anyone! This year, our BioBlitz is completely open to the public. Learn how to get started by watching the video below:
If possible, provide multiple photos of the object from different perspective. For example, a good tree observation can include a photo of the leaves, the bark, and the flowers.

Based on your observations, iNaturalist will propose its identification, often listing several for you to pick from. Unless you know otherwise, select or enter the most general option that is predicted for this area. There are experts on iNaturalist that can confirm your identification.If you come across a plant that you suspect was likely planted by another person, check the Captive/Cultivated box.

iNaturalist has some great videos on how to take better photos for identification:
