Madrona Marsh Preserve

33.82687 , -118.34340

United States of America (USA)

Madrona Marsh Preserve is one of the few vernal wetlands remaining in southern Los Angeles. It has standing water in winter and spring after rains, but is largely dry in summer and fall. The site lies in the traditional territory of the indigenous peoples of the Los Angeles Basin, known as Tongva or Gabrieleno. Having been set aside for oil extraction in the early 20th Century, the 17 ha site was earmarked for preservation in the 1970s.

The Preserve is administered in partnership by the City of Torrance and the Friends of Madrona Marsh, a non-profit organization whose volunteers have undertaken replanting of native plants. The Friends also run a visitor center and offer regular tours aimed at both adults and children. Details are at https://www.friendsofmadronamarsh.com/

The site is well-watched and close to 300 bird species have been recorded, including winter visitors and migrants using the wetlands and breeding birds using the scrub. The Preserve is also important for education and research, from kindergarten vsiits to master's thesis projects.

  • Timing and strategy

The Marsh is most interesting from winter to spring, when standing water attracts a range of water birds. In Spring, shorebirds such as Wilson's Snipe, Solitary Sandpiper and both Yellowlegs species visit. In summer, flycatchers and kingbirds may be seen perched or hawking from prominent branches such as the bare trees in the center of the Preserve.

Some common introduced species are Scaly-breasted Munia, Northern Red Bishop, Pin-tailed Whydah, Mitred and Yellow-chevroned Parakeets.

As birds are most active in the morning, visitors are advised to arrive at 10 when the reserve opens. Given the modest size of the preserve, a quick visit can be made in half an hour, but around an hour would be preferable to explore the whole site. One path more or less follows the perimeter, while another leads from the entrance to the "sump" in the southeast corner which retains water all year round. 

Give recommendations for making your visit as productive as possible.
This may include for instance:
• best season
• best time of the day
• how much time to spend at the site
• best means of locomotion within the site
• recommended routes / areas within the site
• guiding
