Marsh plants and creatures of the sea




Inlets from the ocean snaking through the marshes
This weekend, a mundane, obligatory trip to the Sweetwater Marsh Wildlife National Refuge and Chula Vista Nature Center, with my son and a couple of his friends, turn out a lot nicer than I imagined. I have to commend the boys for being better behaved, then I expected, in light of our docent who was highly `musical'. Beans was not his friend!

It had been years since I had been to the Nature Center. I was impressed with how much it had expanded and how well it was run. Perhaps, it was the time of year, fall -almost winter ( winter starts December 21st), we had a clear and beautiful sight of the whole marsh and the bay, and the city beyond. The pictures do not do it any justice.

I never realized how many endangered species of birds and plants call the Sweetwater Marsh Wildlife Refuge home. Gunpowder Point on the marsh is only known native US population of Palmer's Frankenia (Frankenia Palmeri Wats). Cuttings from the 2 surviving colony is being propagated.  It was interesting to learn about halophytes like the endangered Saltmarsh Bird's Beak (cordylanthus maritimus) also found on the marsh. I was impressed at how the Nature Center was breeding and returning back to the wild the light footed clapper bird, which was almost extinct. More than 300 birds have been released into the wild todate. Such great work done so close to home and I was unaware until duty called.
The Saltmarsh Bird's Beak - extra salt is excreted out making it look like the plant is sprinkled with sugar
You know what else I was unaware of? I knew that there had been a gunpowder factory on the site during WWI . What I did not know is they were processing kelp at the site to produce acetone and potash key components of gunpowder. Imagine that kelp!
