Irvine Ranch Natural Landmarks

Be part of a hiking series inspired by current IRC projects in research, monitoring, and conservation. This rotating series highlights different areas of the landscape depending on the season and ongoing projects.

In this session, we’ll spend the morning exploring Limestone Canyon, observing local plants and animals, and learning how to identify them using the iNaturalist app.

Before arriving, please download the free iNaturalist app and create an account on your smartphone to fully participate in the activity.

During the hike, we’ll stop at 2–3 butterfly monitoring plots for 5–10 minutes each to document the flora and fauna we encounter using the app. It’s a great opportunity to contribute to community science while deepening your connection to the land.

Please note that you will be asked to adhere to the following measures during the activity in order to participate:

• Be registered in advance, no walk-up registration is permitted.
• Arrive with all necessary equipment to keep you safe on the trail, including water, proper attire, and closed-toe footwear, first aid, health needs etc.
• Restrooms will be available, but facilities will not be sanitized for each individual.
• You may be prevented from participating if you do not adhere to the above protocols.

Additionally, in an effort to respect and protect all employees, volunteers, and participants, please do not sign up or attend if you are not feeling well, exhibiting any symptoms of illness or have been in recent contact with someone who was ill.
