EAB Management Strategies

Management Strategies

Saint Paul Forestry has utilized several management strategies to reduce the population growth of the emerald ash borer (EAB). Strategies such as monitoring and insecticide treatment worked to slow the population growth of EAB in Saint Paul, however the city is now considered totally infested. Structured removal of infested trees has allowed for a more diverse pallet of new trees to be planted. This multifaceted approach to managing EAB has spread out the cost of management over a longer, more manageable period of time and allowed for a more efficient response. The following is a list of strategies along with descriptions for reducing the population of EAB. 

Insecticide Treatment

• Treatment of public trees was employed as a means of slowing the population growth of EAB.
• Insecticide treatments have been used on select public property ash trees since 2011.
• Select park and specimen ash trees throughout the City will continue to be treated until further notice.

Permits WILL continue to be required and WILL continue to be issued for public ash trees being treated by the adjacent property owner, however only those trees under an active treatment schedule will be approved.
