Can someone give me the four-one-one on what's causing this and is there a scientific name for it?
Looks like Mother Nature at work decomposing a dead or dieing tree.
You mean the green stuff on the bark???
If so, It's a type of dry algae-moss called "Lichen".
You might want to be a little more specific in what you are asking. Are you talking about the dead tree branch? Rocks? Weeds? Blowing?
If you are referring to the lichen, its harmless to the trees but only grows on slow growing plants thus indicating a fast growing plant may be having issues

Trees is right. About the green lichen--partly the result of high humidity. If you cannot get more air circulation, a fungicide is a possibility. Lichens do not harm the tree. Do not plant junipers too close together, nor where humidity remains high. Do not irrigate frequently. Do not wet foliage when irrigating. Once a week with drip irrigation without wetting the foliage--my suggestion.
My guess is spruce but since @ant didn't give more info hard to know what the question is
