Grassland ground up on the esker…

That’s not soil between the bunches of grass and the flowers and herbs but a layer of blue green algae, lichens, mosses, bacteria and invertebrates…about 100 species per square foot.Here, look closer:

Blue-green algae, mosses, lichens? It’s a lake without the water (or a glacier without the ice.) Don’t be fooled. Even without the water, the lake is there.

 

One thought on “The Hidden Water of the Grasslands

  1. Love it! I was quite surprised to find quite a bit of moss on my last walk at Ashnola. I spent 30 years at sea, there are vast deserts (in relative terms) in the ocean.
