Mallard Ducks on Emerald-green Duckweed Pond (Sweetwater Wetlands, June 16, 2021) — Image by kenne
Duckweed, an emerald-green hydroponic plant, has covered most ponds at the wetlands this summer.
The plant, which grows on the water surface without soil, makes irregular warm-season appearances at
Sweetwater, which doubles as a wastewater treatment facility and lush wildlife habitat.
Duckweed is harmless and disappears naturally in the fall. It removes nitrates from the reclaimed water,
and it’s good for the ducks. It’s a plant that ducks eat, providing a lot of protein.

That reminds me of my younger days: as a child I rode my first bicycle down the path in my father’s garden at the edge of the castle mound in my hometown Linn and couldn’t stop. So I ended up in the moat, which was at that time covered with Duckweed. Luckily it wasn’t deep and I could crawl/walk out. But I looked like the “Monster from the Deep” – covered all over in Duckweed. 😀
Hope your trip is going well.
It’s really fine. Really relaxing now that we’re in Palo Alto.
