Texas Arboretum: Oak Wilt
All oaks (Quercus spp.) are susceptible to oak wilt to some degree, but some species are affected more than others. Red oaks, particularly Spanish oak (Q. buckleyi), Texas red oak (Q. texana), Shumard oak (Q. shumardii), and blackjack oak (Q. marilandica), are extremely susceptible and may play a unique role in the establishment of new oak wilt infections. White oaks, including post oak (Q. stellata), bur oak (Q. macrocarpa), Mexican white oak (Q. polymorpha), white shin oak (Q. sinuata var. breviloba), Durand oak (Q. sinuata), Lacey oak (Q. laceyi), and chinkapin oak (Q. muehlenbergii), are resistant to the fungus and rarely die from oak wilt. Live oaks (Q. virginiana and Q. fusiformis) are intermediate in susceptibility to oak wilt, but are most seriously affected due to their tendency to grow from root sprouts and form vast interconnected root systems that allow movement (or spread) of the fungus between adjacent trees.Printer Friendly: Species List | List with Images | List with QR Tags to Mobile
