What is Structured Removal of ash?
The City of Saint Paul has, since 2010, employed the "Structured Removal" of ash in order to strategically reduce the total percentage of ash trees on boulevards and in parks throughout Saint Paul.
How are trees selected for structured removal?
In the past, the focus for structured removal was on areas that were planted in a monoculture of ash trees. Trees that were declining from non-EAB related causes such as drought, salt injury, mechanical injury, and structural defects, were selected for structured removal. In general, ash trees become brittle and drop many branches while reaching maturity and are a common source of complaints from residents.
Due to the continuing spread of the infestation, and to the growing number of infested trees, structured removal now focuses exclusively on confirmed infested trees. These blocks are identified during routine monitoring for EAB infestations.
Why are you removing live trees?
Once an ash tree becomes infested with EAB, it generally takes 3 to 5 years for the tree to die. By removing these trees before mortality occurs, the city is reducing the number of dead and potentially hazardous ash trees in the city. Also, the removal of these trees becomes much more dangerous when they are dead or nearly so. The safety of the citizens of Saint Paul as well as the crews maintaining the urban forest are a top priority.
Why not save the trees with insecticide treatments?
Forestry treats a portion of the high value ash trees on boulevards and in parks that meet the following criteria:
What happens once ash trees in the structured removal program are removed?
Removals generally begin early in the year and continue throughout the year until completed. Once the ash trees are removed and weather permits, stumps will be removed. This means there could be several months from the time the tree is removed to the time the stump is removed.
Replacement tree planting takes place twice during the year—Spring (April-June) and Fall (October-November). Due to the number of trees scheduled for removal and the short timeframe for stump removal prior to spring planting, it will not be possible to plant all replacement trees in the spring.
