TECHNICAL TERMS: <br />2. It is very strongly suggested that all clearing in oak stands be done before <br />April 1s and after July 1S of each season. This will help prevent oak wilt, <br />which could infect damaged trees, especially during this high -risk period. <br />If clearing has to be done at this time, all stumps and wounded trees shall <br />have the wound area painted thoroughly with tree paint. To be effective, <br />the painting shall be performed within an hour of cutting. Should oak wilt <br />get started as a result of construction, the developer /builder shall pay for <br />all additional oak wilt control measures needed to control the disease. <br />This is in accordance with City Code 4 -3. <br />3. Where the NRT or their designee has determined that irreparable <br />damage has occurred to trees within tree protective zones, they must be <br />removed and replaced by the developer /builder as defined in Section <br />IV(B)9. <br />TREE PRESERVATION POLICY <br />CITY OF ANDOVER <br />COUNTY OF ANOKA <br />STATE OF MINNESOTA <br />APPENDIX A <br />Cambium — tissue within the woody portion of trees and shrubs which gives rise to the <br />woody water and nutrient conducting system, and the energy substrate transport system <br />in trees. <br />Cambial Dieback — the irreparable radial or vertical interruption of a tree's cambius, <br />usually caused by mechanical damage, such as "skinning bark ", or from excessive heat. <br />Coniferous — belonging to the group of cone bearing evergreen trees or shrubs. <br />Critical Root Zone — the rooting area of a tree established to limit root disturbances.
