CANCELLED due to Fire Weather: 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.

CANCELLED due to Fire Weather: Seasonal Science Series: Western Spadefoot Toad 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 project.

The Western Spadefoot Toad (Spea hammondii) success depends on IRC’s project to protect, restore, and enhance its breeding habitat. In collaboration with United States Geological Survey, IRC staff and volunteers have been monitoring vernal pools located at Shoestring.  Although these areas are sensitive habitat, we feel it’s important to highlight some of our ongoing projects that benefit some of our rarer and at-risk species.  Want to learn more?  Perfect! This hike will be approximately 3.5 miles out and back from the Augustine staging area along Shoestring single track up to the ponds where we will discuss the project in depth.
