Coastal sage scrub is like a big garden that grows along the coast of California. Imagine you have a huge area filled with lots of plants and animals living in it. The plants are mostly short and grow close together, like bushes. They have small green leaves that grow in clusters, and some even have pretty flowers that bloom in the spring.
These plants are used to living in places where it's really sunny and dry, so they don't need a lot of water to survive. They also have a special smell that some people think smells like sage, which is where they get their name.
Now, because there are so many plants growing in this coastal sage scrub garden, it's also a great place for animals to live. Rabbits, squirrels, and lots of different types of birds like to make their homes here.
But sometimes, people will come in and use parts of the coastal sage scrub for building homes or businesses, which can hurt the plants and animals that live there. That's why it's important to protect these areas and make sure they stay healthy for all the creatures that depend on them.
