Only for the purposes of interpreting this chapter, the following terms, phrases, words and their derivatives shall have the meanings given herein; words used in the singular include the plural.

(d) "Conifer" means a tree with needle leaves and woody cone fruit.
(e) "Criticalroot zone (CRZ)" means the circular area surrounding a tree in which the tree’s roots critical to its survival usually will be found, and which should be protected. The radius of the CRZ in feet is typically 1.5 times the DBH in inches. By way of example, if a tree’s DBH is ten inches then the CRZ is 1.5 times ten, resulting in a CRZ radius of fifteen feet.
