Growing Together at the Native Seed Farm

Looking for a way to give back to Nature this Spring? Come help us behind the scenes at the Irvine Ranch Conservancy’s one-of-a-kind Native Seed Farm in Irvine! Every day at the farm is different; depending on the needs of the farm we will be harvesting seeds from beautiful native plants, planting new seeds in the annual plots, working in our native plant demo garden, or tending to younger seedlings in our nursery.
Working with us at the Native Seed Farm is a great way to grow your community and cultivate knowledge about local plant and wildlife! Absolutely no experience or special equipment required!
Native Plant I Spy

At the Native Seed Farm, it is crucial to collect a variety of genetic material from different individuals within a plant species, so that an array of characteristics (flowering/seed times, size, tolerance to sun, and many more factors) are represented when incorporating it into IRC’s restoration projects. Although the Irvine Ranch Open Spaces are well loved and used by the community, they are some of the most under-documented open space areas in Orange County. For future seed collection efforts, it is crucial to document location data for populations so that we determine accurate identifications for hard-to-determine species, have current location data, and know the best time for collection. When seed collection season starts in the summer, it can be difficult to know exactly where some populations are due to many perennial plants going dormant or annual plants dying out.
To assist with providing new genetic material, Plant Materials staff are asking for volunteers passionate about native plant identification to help record populations in under-documented areas within the the Irvine Ranch Open Space. No prior plant documentation or identification is required, but a smart phone or camera with GPS capability is heavily encouraged. All observations will be uploaded into IRC’s group Calflora account to help staff with assessing collection areas for the seed collecting season.
Spring Morning Fitness Hike with Yoga at Quail Hill

Join us on a five mile out and back moderate fitness hike (averaging about 3 mph) before experiencing yoga outdoors at the Community Center.

The yoga is suitable for those with little or no experience, focused on hips, legs and core. Our focus on breath calms the nervous system and has positive effects on mental, emotional and physical health. If you have never done a yoga hike before you will be surprised how connected you feel to nature. Please bring water, your own yoga mat plus a large beach towel, and wear shoes appropriate for hiking on trails.
Seasonal Science Series: Spring Social Butterfly Habitat Enhancement

Join us for a slow-paced interpretive hike related to current IRC projects focused on research, monitoring, and conservation. The series will rotate through the landscape based on the season and projects.
For this series, we will spend the spring morning hiking along beautiful Limestone Canyon where we will focus on the butterflies in Limestone Canyon, and the newly created butterfly habitat plots. These plots were seeded and planted with a variety of both host and nectar plants to aid the documented, declining population of butterflies in the canyon. We will hike through Limestone canyon plot by plot, and up to Dripping Springs, a natural water source dripping out of an earthquake fault and down a gorgeous fern-covered rock face.
