Moss can be found all over the world, from tropical rainforests to arctic tundras. It is especially well adapted to moist, shady environments, and is commonly found growing on the forest floor, on rocks and stones, and along streams and rivers. Moss does not have roots in the traditional sense, but it absorbs water and nutrients through tiny hair-like structures on its leaves.
In the PNW, moss is found everywhere. I am always drawn to photographing them because to me they represent a miniature world of their own. I think of a moss forest pretty much like the one you see below as having its own ecosystem with several insects and other organisms going about their day-to-day life with no care for the world around them.
