The Wadi Dawkah
Here is a tree I've heard of but never seen. These gnarly desert trees produce the prized aromatic resin traded along the ancient incense trail.
Frankincense is one of those words with strong biblical associations and relatively little everyday use. That is, if you’re not in or from the Arabian Peninsula.
Unfortunately, frankincense trees have drastically decreased in number over the years due to over-exploitation. The natural park in Wadi Dawkah has the dual purpose of protecting the existing trees and growing new ones in order to increase the population of frankincense trees in the wadi.
Clancy's comment: Interesting, eh? I can only assume that this tree provides the incense used in modern church services.
