Oak Wilt is a contagious fungal disease that can kill many species within just a few months. While an outbreak often starts with sap-seeking beetles which carry fungal spores from an infected tree to an open wound or fresh cut of a healthy tree, the disease quickly spreads to nearby trees via interconnected root systems.

 

Once an outbreak starts it's nearly impossible to contain. Timely application of fungicide can spare many oak species, but without treatment fewer than 10% will survive. Fungicide is typically 75% less expensive than removing a dead tree, so WOHA strongly urges residents to consult a qualifed arborist when the risk is imminent. 

​

The East side of Whispering Oaks has battled an outbreak for over a decade with moderate success (details here). Unfortunately, the disease is still progressing and has caught some residents off-guard, resulting in costly tree removal which can undermine a property's appeal and value.

​

WOHA partners with Texas A&M Forestry Service to track the outbreak which progresses approximately 100 feet each year. Staff update the map below every 12-24 months.
