Irvine Ranch Natural Landmarks are rich in oak-filled valleys, expansive grasslands and plentiful coastal sage. Protecting those lands from invasive non-native plants to keep wildlife thriving takes attentive, consistent and continuous dedication.
This is where community volunteers have the biggest impact – dedicating muscle and manpower to protecting nearly 40,000 acres of open space. Even the smallest amount of effort goes far in habitat restoration; for instance, a modest team of workers last week pulled 20,000 invasive plants from OC Parks’ Limestone Canyon Nature Preserve in just two days.
