The first sample of the year… always a pleasure. Even more so, when one does not have to travel far nor carry a lot of equipment. I just walked to the other side of our garden with an empty yoghurt can in my hand.
Near the rock there are two deeper places on the ground, which are filled with water if it has been wet. And it has. The water is not only surface water, because it stays there much longer than just after rain. A bit higher there is a well and the water is probably running further underground somewhere near the rock.
Anyway. In the pools there has always been an interesting flora of desmids. Now, in the early spring the diatoms were dominating. But yes!! There were also some beautiful, bright green desmids, like Staurastrum spongiosum var. spongiosum – the star of Betlehem as I like to call it now.
No, they were not ancient either, they settled here only about 120 years ago.
