What does the D in MAD HORSE stand for?

The D in MAD HORSE stands for Dogwood, which is significant because it represents a tree that exhibits opposite leaf arrangements. In the context of forest ecology and forestry practices, knowing the arrangement of leaves on a tree is crucial for identification and understanding of tree species. Dogwood trees are commonly found in eastern North America and are characterized by their distinct flowers and leaf patterns, which provide critical points of reference for ecologists and forestry professionals.

The alternative options describe various plants or terms, but they do not relate to the specific mnemonic MAD HORSE used for identifying tree species with certain leaf arrangements. Understanding dogwood’s leaf arrangement and its positioning within the larger context of tree identification contributes to the knowledge necessary for anyone studying forestry.
