Ewest, this is an interesting picture of exposed BG/RES spawning beds
.
Early last year we had a massive invasion of bushy pondweed..
When the water was at lowest drought stage, we had BG beds exposed on top of dead pondweed that looked very similar to your pictures.
Proved to me that BG will spawn on anything.
Wish now that I had taken a picture.
