Coniferous/evergreen tree species shall be replaced with new coniferous or evergreen trees at a rate of one-half (1/2) the diameter inches removed. Since coniferous species are often sold by height rather than diameter inch, the following conversion formula can be used: Height of Replacement Coniferous Tree/2 equals Diameter Inches of Credit. c. Hardwood deciduous tree species shall be replaced with new hardwood deciduous trees at a rate of one- half (1/2) the diameter inches removed. d. Replacement tree size.
