Scientific research depends on data. Lots of it—sometimes more than any group of scientists can collect themselves. So researchers rely on regular folks and events like BioBlitz to help them collect it. Participants in the BioBlitz at Foothill Regional Park in Windsor will take a guided hike (suitable for all ages and abilities) to collect data about the diversity of plant and animal species in the park. Then they’ll download what they find to a global scientific database. To assist them with their task, prior to the hike BioBlitzers can download the free app iNaturalist to their smartphones. The event will be held on September 11, 9:30–11:30 a.m.; registration is required. Learn more and register at tinyurl.com/bdz82rx8.
