Open Space Invaders: Invasive Plant Removal at Agua Chinon

Stewardship
Open Space Invaders: Invasive Plant Removal at Agua Chinon

Non-native and invasive plant species are invading our native habitat and open spaces. They aggressively compete with our native plants for resources and spreads rapidly once established. Monitoring, management, and removal of these plant species is an important aspect of land management and habitat restoration.

Help us to manage populations of invasive plants and remove them from the habitat. No previous experience is necessary, just a desire to work outside and get dirty! Snake chaps, gloves, and tools will be provided but please feel free to bring your own if you have them. Please wear long pants, long sleeved shirts, close toed shoes, and protective sun protection. Note: This is a wilderness area, there are natural hazards. Snakes, including rattlesnakes, are occasionally seen here.

Native Plant I Spy

Stewardship
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.

GSOB Monitoring in Oak Woodlands of Upper Weir Canyon, Volunteers Only

GSOB Monitoring in Oak Woodlands of Upper Weir Canyon, Volunteers Only

The Gold Spotted Oak Borer (GSOB) is an introduced non-native invasive beetle that is greatly impacting our native oak species. IRC is working to enhance and protect our oak woodland habitat by monitoring oaks throughout the landmarks in some of our major canyon bottoms. Join our annual GSOB monitoring efforts and help protect the oak woodlands on the Irvine Ranch Landmarks.

GSOB Monitoring- Participants will learn about the signs and symptoms of Gold Spotted Oak Borer infestations in oak trees, as well as survey techniques for detecting GSOB. Using a mobile data collection app, participants will locate known infested trees, inspect trunks for GSOB specific exit holes, identify and mark the holes, and update the data collection form for each surveyed tree. More information will be given at the training for future monitoring activities.
