The City of Brentwood is implementing a plan to reduce the impact of the Emerald Ash Borer (EAB), an insect that has been responsible for the death of over 100 million Ash trees in the United States and Canada. With 260 Ash trees – over 8% of the City’s Urban Forest – the EAB will have a clear impact on the City of Brentwood. Unfortunately, the Emerald Ash Borer is in Brentwood. Staff has found evidence of the borer in all four wards of the City.
The City is using resources to manage this invasive pest while analyzing the impact on the tree canopy and ensuring public safety.
In 2017, the City of Brentwood authorized the implementation of the Parks & Recreation Department’s recommended Emerald Ash Borer Plan. The plan includes the removal of every Ash tree over a span of five years, to stay ahead of the Ash-mortality curve. The plan prioritizes public safety. We want to ensure that trees are removed ahead of the mortality curve, so they don’t become diseased and then fall, causing personal or property damage. All trees will be replaced.
Since trees provide excellent defense to creek erosion, any time a tree along a creek needs to be removed, we do not remove the stump. The primary benefit for erosion control is the root system. By not removing the stump, this also allows another tree near the tree that was removed time to grow and establish a root system.
