What to expect: 🗣️🌱🐾
As the sun begins to set, many of California's most fascinating species start to emerge. Join us for a guided Twilight BioBlitz hike at the San Diego National Wildlife Refuge where we will use the iNaturalist app to record our sightings of plants, insects, birds, and other wildlife! This is a great way to connect with nature in a whole new light while contributing to biodiversity science.
