City Nature Challenge at Cabrillo National Monument – A Celebration of Science for the Entire Community

The students of High Tech Elementary School brought their families along to join in the BioBlitz fun.

May 2019 - The Natural Resource Management and Science Division of the National Park Service is tasked with the preservation and protection of the incredibly abundant natural resources of our national parks. Such a monumental job is a challenge for the scientists the NPS employs – thousands of species inhabiting millions of acres can be extremely difficult to monitor, and scientists don’t always have the time or the manpower to do so. One of the best solutions to these challenges is that of citizen science projects. Such projects harness the power of the people to assist in data collection and analysis, fostering a sense of community as local enthusiasts get involved. There are many NPS citizen science projects: from restoration work, to birding, to phenology programs, to climate effects on trees, the community is helping to serve the mission of the NPS. One such program just occurred at Cabrillo National Monument – a 24-hour BioBlitz!

A BioBlitz is a concentrated effort to discover and document as many species of plants, animals, and other organisms in a certain period. This helps map the biodiversity of a given area and can be used as a tool to measure impacts and changes over time. Such a “snapshot” of biodiversity is a great way to connect the community with citizen science and the outdoors in a fun, interactive, and engaging way. Cabrillo’s BioBlitz was held in conjunction with the City Nature Challenge, where cities across the world competed for the highest number of species, observations, and observers. Utilizing the free platform iNaturalist, participants made observations of organisms around them and posted these observations to a database that’s used by organizations such as the Global Biodiversity Information Facility (GBIF) and researchers across the globe. This crowdsourcing event racked up 2,096 observations and 444 species – in one day, participants of Cabrillo’s BioBlitz accounted for approximately 20% of all of San Diego County’s observations for the entire four-day span of the City Nature Challenge. But even more than this substantial scientific contribution is the creation of community amongst fellow science, nature, and national park enthusiasts. Scientists, school children, families, teachers, volunteers, park staff, and the public all got together to marvel at the beautiful biodiversity Cabrillo has to offer. This fact alone makes for a successful citizen science project – in this rapidly changing world, the people’s support of the NPS mission to preserve and protect is more crucial than ever.
