Words used in this article and not defined in this article shall have their ordinarily accepted meaning. For the purposes of this article, the following words and phrases shall have the meaning respectively ascribed to them by this section:
Diseased trees.
Oaks confirmed to be infected by the fungus Ceratocystis fagacearum (oak wilt).
Firewood.
Wood larger than two inches in diameter cut from diseased oaks; also wood from an unknown source that may potentially harbor the oak wilt fungus.
Fungicide.
A chemical treatment used on non-symptomatic or slightly symptomatic trees within the trench line that could be vulnerable to infection.
Live oaks.
Members of a distinct group of the genus Quercus characterized by leathery oval leaves that includes two Texas species: plateau live oak (Quercus fusiformis) and coastal live oak (Quercus virginiana).
Nuisance.
Any tree infected by oak wilt or any firewood and woody debris from a tree suspected to have died from oak wilt, as determined by an approved laboratory analysis or from field diagnosis as performed by the city forester or state forest service staff forester, are hereby declared to be a public nuisance.
Oak wilt.
A vascular wilt disease of oaks. The fungus responsible, Ceratocystis fagacearum, invades the water-conducting tissues of oak roots, trunks, and limbs. Ceratocystis fagacearum does not actively grow anywhere in nature except in oak trees. Spores of this fungus can be moved around by certain insects and by humans.
Oak wilt center.
A site where the oak wilt fungus is spreading through the roots of diseased trees to infect healthy oaks, creating an area of sick, dead and dying oaks.
Preventive measures.
Actions that prevent the spread of oak wilt from diseased to healthy oaks, including but not limited to oak wilt suppression trench installation and the removal and destruction of diseased oaks and firewood.
Red oaks.
Members of a distinct group of the genus Quercus characterized by lobed leaves tipped by small soft spines, including but not limited to Texas red oak (Quercus texana, also called Quercus buckleyi), Shumard oak (Quercus shumardii), Southern red oak (Quercus falcata), and blackjack oak (Quercus marilandica).
Substantially dead tree.
Oaks in which more than 90 percent of the previously healthy branches have died due to oak wilt infection.
Susceptible species.
All varieties of the genus Quercus that may be infected and killed by Ceratocystis fagacearum, including live oaks and all species of red oaks.
Trenching.
Short for “oak wilt suppression trench installation,” a method used to isolate the infected area between healthy and diseased trees. Trenching equipment is used to cut connecting roots so that the fungus cannot spread between trees.
Woody debris.
Branches and limbs smaller than 2 inches in diameter cut from diseased trees.
