City Nature Challenge - BioBlitz

In cooperation with The City Nature Challenge, Cabrillo National Monument is hosting a BioBlitz! The event will occur on April 26th and 27th. On Friday, April 26th, Cabrillo National Monument will be open to researchers and registrants. These individuals have observed and collected data in the past and are coming back this year to continue their research and efforts on the Park’s biodiversity. On Saturday, April 27th, whether you are a scientist, a naturalist, or a lover of national parks Cabrillo encourages those to come out. This day will have something for everyone!

Description: Cabrillo National Monument will participate in the annual City Nature Challenge. The challenge is an effort for people to find and document as much biodiversity as possible in a given area. Cabrillo National Monument is joining the challenge by hosting a BioBlitz at the park! Our focus is to gather as much data as possible on different species of plants, animals, and other organisms in the span of 2 days. The individual will use an app called iNaturalist to document the wide range of species. iNaturalist is free to download on any mobile device. Along the way, you will be able to meet incredible scientists and help assist one another to learn about the world around you. Not only is this a friendly competition, but it is also a fantastic way for the community to connect with science and the outdoors in a fun, interactive, and engaging way. These efforts will help educate the public and support the park in continuing to preserve biodiversity!

Searchlight Shelter (Saturdays)

From 10 am to 12 pm on the Bayside Trail, volunteers give park visitors the opportunity to view a 60-inch-high intensity carbon arc searchlight up close. The searchlight was built in 1941 and the shelter in which it is housed was built in 1918. This searchlight, along with others placed throughout the San Diego Harbor, provided a vital part of the United States Army’s overall defense against “sea-borne” attacks.
