Question:

What’s the SPF of a deciduous forest?

Submitted by – Jason – Columbus, OH

Answer:

Well, sir, it is an interesting question. But, it has no specific answer that I know of. No two forests grow exactly equal. The SPF of shade is highly relative. In a deciduous forest, it is relative of course to the density of the trees and their leaves, and the time of year. One fact is certain: all

shade provides some protection from UV light, and the more shade the more protection.
