Aggressive Native

 Girdling, done properly, offers nearly 100% control.

 Alternative control practices:
 Chemical: basal bark, cut stubble, cut stump, foliar
 Mechanical: forestry mower, light mower,  chainsaw, clearing saw
 Rx fire: seedlings highly susceptible, adults negatively-impacted  
 Biocontrol: grazing offers limited control

 Note: Alternative control practices often cause suckering.
