Do you love bats?

FACT: There are 23 bat species in San Diego County - 5 of these are at-risk.


The San Diego River Park Foundation is raising awareness about these amazing critters which are so important to the river's ecosystem. We have documented bats at many places along the San Diego River and its tributaries.

    Reasons Bats are cool:

  • Bats are vital to an ecosystem
  • Bats help by distributing seeds
  • Bats are great pollinators
  • Some bat species eat mosquitos and other pests
  • Bats use echolocation to navigate and can determine size, shape, speed, and direction as they detect different features.

Join a Bat Walk to learn more!
If your are interested, contact our team and they can let you know about the next event.

We also post upcoming bat walks on our event calendar. Click here for calendar


Special Projects

Boulder Creek Preserve is an amazing place where 14 bat species have been documented. 3 of these are at-risk species. Together we can help save these bats!

ACTION: Our program seeks to protect known roosting sites, create a bat research site to collect data to fill in knowledge gaps about these nocturnal critters, and raise awareness through bat walks, student education programs and other activities.

2023 Objectives: Maintain 2 bat research stations (Eagle Peak Ranch and Boulder Creek)

BACKGROUND: On one of the properties we conserved along Boulder Creek at the base of Cuyamaca Peak, we identified an old mine. After exploring the mine, we found bats roosting in it. We applied for and received a grant from SANDAG to install a "bat gate" to help protect people and the bats and study this bat population. We have been amazed at how many different bats are in and around this mine. 14 species have already been documented.

We worked with the San Diego Natural History Museum to document these bats, obtain the equipment to continue this research, and take actions to protect the mine and surrounding areas. We would love for you to join with us to care for this wonderful population of bats along Boulder Creek and elsewhere. We will take what we learned and the equipment that has been provided to expand this work to Mission Valley and to our other preserves.

Next Steps:

We plan on holding more bat appreciation events throughout the year and will expand our bata data collections activitites in Mission Valley, Eagle Peak Ranch and elsewhere.

The bat data will also be used in our Nature Education Program as we develop an element called "Bats are Cool" and support our bat conservation efforts.

With your support we can take actions to conserve these amazing critters!
