Invasive species in California, the introduced species of fauna−animals and flora−plants that are established and have naturalized within California. Native plants and animals can become threatened endangered species from the spread of invasive species in natural habitats and/or developed areas (e.g. agriculture, transport, settlement).
California is in one of the world’s 36 biodiversity hot spots and is home to more than 6,000 types of native plants, including hundreds of wildflower species. Only a few other places on Earth ...
Which Southern California native plants survived climate change and mass extinctions 13,000 years ago and still live today? La Brea Tar Pits researchers compiled a list.
