Dear Neighbors,
Several trees throughout Abbottsford have rapidly declined in the last few weeks (photos attached). Plant pathologist, Dr. Sylvia Moraes, at the UT Soil, Plant, and Pest Center has analyzed several samples collected from trees throughout Abbottsford. More samples are currently being evaluated. Slime Flux or Bacterial Wetwood was identified on the two dead/dying maple trees at the top of Overton Park across from the clubhouse and playground area. A third maple at the bottom of that upper median is also showing signs of slime flux. The bacteria spreads to nearby maples if their root systems touch, so all maples in that area may need to be removed and replaced with another species of tree. Slime Flux cannot be cured and infected trees must be removed.
Granulate Ambrosia Beetle (GAB) larvae and adults were found in a Redbud tree at the base of the walkway between Foster Hill and Greenwich Park. Infested trees must be removed and burned to prevent the spread of these destructive beetles. The beetles are tiny (1mm-2mm), but can kill trees quickly. They prefer thin-barked, deciduous trees such as Redbuds, Dogwoods, Ornamental Cherry, Japanese Maples, and over 90 others. Unhealthy trees are most at risk. I will work with arborists to monitor trees for any signs of GAB, but I could use your help. Please keep a watchful eye out for any signs of tree decline or if you notice any distinctive Frass tubes shown in Figure 5 of this Article. Report any concerns to me immediately.
Thank you for your help.
