Thursday July 5th
The San Fernando Valley Iris Society is happy to present Tracy Drake on the Madrona Marsh Preserve The Madrona Marsh Preserve, in the city of Torrance is a seasonal wetland with vernal pools. The 43 acres was a former site of oil wells and is one of the few natural areas remaining within an urban landscape.
Formed eons ago when the mountains of the Palos Verdes Peninsula rose to the south, Madrona Marsh is a shallow depression fed by wet season (spring) storms as the name "vernal" indicates. After the rainy season, evaporation , percolation and transpiration reduce the water depth by about one-quarter of an inch per day.
Situated on land that was set aside for oil production in 1924, Madrona Marsh was never developed while the city grew up around the site and remains a valuable natural habitat for birds, reptiles, insects and small mammals. The City of Torrance operates the Madrona Marsh Nature Center in cooperation with the Friends of the Madrona Marsh. Activities include bird and nature walks, natural history classes and workshops, habitat restoration, science and astronomy programs, art exhibits, and
children's nature programs. The center opened in 2001 and features exhibits about the plants, birds and animals of the marsh. The nature center for the Preserve is across the street. Tracy Drake will be the speaker for the evening and will tell us all about this interesting wildlife place so close to home.
Meetings
are held on the first Thursday of each month at the Canoga Park Women's Club,
