Growing In/On Rocks

I photographed a lot of organisms growing on the rocks when we made our tour of state parks in southern New York (Stony Brook, Robert H. Treman, Taughannock, and Letchworth). Most of the gorges are crumbling shale - small and large slabs. Since we are focused on waterfalls - some of the plants were cling to wet or damp rocks.

There were mosses and ferns that see to require very little soil

Others that grew in a bit more soil in the cracks…or lichen that grows on the surface of rock, breaking away small bits of the stone over long periods of time.

Any structure built of stones seemed to have colonized by something from algae to lichen to liverworts to mosses to ferns to higher plants. I enjoyed taking pictures of the small landscapes on the rock walls of the gorges and the walls/bridges that had been constructed for the trail. Enjoy my picks for the slideshow below!
