Live Oak Bark Falling Off: Squirrel Damage, Not Oak Wilt

Live oak in Austin, TX (drought area, irrigated lawn) shows patches of missing bark on 2-3 inch branches, with bark pieces on ground. Tree has full green canopy but increased leaf drop for 2 years. No insects seen on bare wood.

Diagnosis

Oak wilt causes vascular symptoms, not bark loss. Photos indicate physical damage—likely squirrels stripping bark. Drought stress may increase squirrel activity.

Action Plan

Request free home visit from county Agricultural Extension horticulturist for confirmation. Protect tree from further mechanical injury. Maintain consistent irrigation. No disease treatment needed unless secondary infection develops.
