Bugs, plants, birds. Search for all of them at Bioblitz at the Hopland Research and Extension Center (HREC). Families will be guided to look for as many species as possible and then record what they find on the free iNaturalist app. One-hour guided visits will take place 10 a.m.–1 p.m. on April 10, 17, 24, and May 1. Admission is on a sliding scale, $10–$100. Register online at bit.ly/hrecevents. There will also be two-mile self-guided hikes on the HREC property, populated with oak woodland and pastures, on April 3, 10, 17, and 24. Hikes are priced on a sliding scale: 0–$10. Register online at bit.ly/hrechike. Mendocino County health orders will be followed during Bioblitz and hikes.
