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 that transmit disease spores from an infected tree to an open wound or unpainted cut of a healthy tree, the mostly spreads to nearby trees through interconnected root systems.

The East side of Whispering Oaks has battled an outbreak for several years with some success (details here). Unfortunately, the disease is still progressing and some residents have failed to take precautions resulting in costly tree removal which can undermine a property's appeal and value.

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


This page also provides answers to common questions about the disease and includes referrals to properly certified arborists which can assist residents.
