TRUCKEE, Calif. — Nature enthusiasts are invited to join a team of like-minded volunteers and scientists in early July at Sagehen Creek Field Station for a BioBlitz.

This is a detailed study of biodiversity in a specific location over a specified period of time. You will have the opportunity to explore one of the natural jewels in the University of California Natural Reserve System while contributing to a data collection that is actively being used in global scientific research.

Your team of 5-10 participants will be paired with a California Naturalist who will guide you to shady forests, colorful mountain meadows, brushfields buzzing with insects, and cool creeks.

An additional expert in plants, insects or birds may also join you. Your job will be to use the iNaturalist app on your smart phone to take photos of every bird, mammal, reptile, butterfly, insect, spider, tree and flower that you see.

There is even an evening session if you have a passion for insects, moths and nightjars. And you won't want to miss the free barbecue for BioBlitz participants‹an opportunity to share your unique sightings and stories.

Although a working knowledge of biology is appreciated, don't worry if genus and species aren't typically in your vocabulary as there are experts who will review your photos on iNaturalist and properly identify them.

Confirmed identifications become "research grade" and are available to all for scientific or recreational study on iNaturalist and worldwide databases such as Calflora and GBIF (Global Biodiversity Information Facility).

And, if you're not keen on smart phone photography or using the iNaturalist app, there is an optional practice session to build your skills and confidence
