Madrona Marsh facts for kids
The Madrona Marsh Preserve is a special natural area in Torrance, a city in Southern California. It's a type of wetland called a "seasonal wetland" with "vernal pools." This means it fills with water during the rainy season and then dries up later in the year. Even though it's in a busy city, this 43-acre preserve is one of the few natural spots left. It used to be a place with oil wells, but now it's a valuable home for many plants and animals.

What is Madrona Marsh?
The Madrona Marsh was formed a very long time ago. When the Palos Verdes mountains rose to the south, they created a shallow dip in the land. This dip became the marsh. It gets its water from spring storms during the wet season. The word "vernal" means "spring," which tells us when the water arrives.
How the Marsh Changes
After the rainy season, the water in the marsh slowly disappears. About a quarter of an inch (6 mm) of water goes away each day. This happens because of:
- Evaporation: Water turns into vapor and goes into the air.
- Percolation: Water soaks down into the ground.
- Transpiration: Plants release water vapor from their leaves.
By the end of August, the marsh is usually dry. It stays dry until the next rainy season brings water back.
A Special History
The land where Madrona Marsh sits was set aside for oil production in 1924. But unlike the areas around it, this spot was never built on. While the city of Torrance grew all around it, the marsh remained untouched. This is why it's such an important natural habitat today. It provides a home for many birds, reptiles, insects, and small mammals.
A Home for Wildlife
Many efforts are underway to bring back native plants to the marsh. This includes beautiful wildflowers. These new plants can help local butterfly species, like the rare Palos Verdes blue butterfly.
Birdwatching and Learning
The Madrona Marsh has been a popular spot for bird watchers for a long time. The Audubon Society, a group that cares about birds, has counted birds here every year since 1967. The marsh is also used by El Camino College as an outdoor biology and botany lab. Students can study plants and animals in their natural setting.
Learning and Fun at the Nature Center
The City of Torrance runs the Madrona Marsh Nature Center with help from the Friends of the Madrona Marsh. This center offers many fun and educational activities for everyone.
Activities at the Center
You can enjoy many things at the Nature Center, such as:
- Bird and nature walks to explore the preserve.
- Classes and workshops about natural history.
- Programs to help restore the habitat.
- Science and astronomy programs.
- Art exhibits.
- Special nature programs just for children.
The Nature Center opened in 2001. It has exhibits that teach you all about the plants, birds, and animals that live in the marsh. The center is located just across the street from the preserve itself.
