National parks and participating partners shared their BioBlitz activities via social media, using the hashtags #BioBlitz2016 and #FindYourPark. During the weekend's event, #BioBlitz2016 ranked in the top 10 on Twitter! At Cabrillo National Monument, Green Abalone (Haliotis fulgens) was documented. For the past thirty years, abalone have faced substantial conservation concerns due to overharvesting and disease. Their presence in the Cabrillo Rocky Intertidal Zone can be described as ephemeral at best. Knife River National Park conducted an ArcheoBlitz. A centuries-old bison tooth was found at Big Hidatsa Village, which was occupied from about 1740 to 1850. DNA extracted from this tooth can provide data on bison populations before their near-extinction at the end of the 19th century, a useful comparison for managers of modern herds. At Great Smoky Mountain National Park, experts teamed up with about 100 5thgraders. Together they set out to explore pollinators and succeeded in discovering nearly 200 species. While it is too early to tell if they found any new species, they have added significant information to the park's database. Craters of the Moon National Monument and Preserve conducted a lichen survey and added several new species to their park list. One of those identified is Xanthoria elegans. This species of lichen survived an 18-month exposure to solar UV radiation, cosmic rays, vacuum and varying temperatures in an experiment performed by the ESA outside of the ISS. Channel Islands National Park broadcast a dive with oceanographer and National Geographic Explorer, Dr. Sylvia Earle, with support from the National Park Trust. The feed was featured online and on the jumbotrons on the National Mall and enabled the public to follow the exploration of one of the richest marine ecosystems in the world, the giant kelp forest. The National Parks BioBlitz used the iNaturalist app to deliver real-time information on species finds. Verified data will be included in National Park Service databases and international databases tracking biodiversity on the planet. This application can be used by parks and citizen scientists well into the future. Beginning with the 2010 NPS/NGS BioBlitz at Biscayne National Park, NPS initiated a corps of Biodiversity Youth Ambassadors. Each year through 2016, a student ambassador is selected by the host park to participate in the BioBlitz and assist in
