The Costly Threat of Oak Wilt
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.
This page provides answers to common questions about the disease and also includes referrals to properly certified arborists which can assist residents.
Map of Eastside Outbreak
On Tuesday, January 24th, Erin Davis of the Texas A & M Forest Service briefed Whispering Oaks homeowners on the Oak Wilt disease killing trees in our neighborhood. She presented this map compiled 3 months ago; now visible spread has occurred to the south across Whispering Wind street and to the north apparently into the drainage channel between Whisper Path and Whisper Fawn. Homeowners are advised to contact a licensed arborist to determine their treatment options.
