More info for the terms: competition, fuel, hardwood
Blackjack oak is probably susceptible to most insects and diseases that
attack eastern oak species. Twolined chestnut borer (Agrilus
bilineatus) and the canker fungus, Hypoxylon atropunctatum, have been
associated with dead blackjack oaks [21].
Hardwood competition in pine plantations and hardwood expansion into
grasslands are often controlled with herbicides. Tebuthiuron and
triclopyr are effective in killing blackjack oak in grasslands of the
Cross Timbers area of Oklahoma [52]. Velpar L, Garlon 3A, and Krenite
were tested on blackjack oak that ranged between 4 and 9 inches
(10.1-22.9 cm) in d.b.h. Velpar L was effective at killing blackjack
oak at all injection spacings (3, 5, and 7 inches [7.6, 12.7, and 17.8
cm]) in both May and December. Garlon 3A was effective only in May at
all spacings, and Krenite was effective only at the 3-inch (7.6 cm)
spacing in May [10].
Blackjack oak expands into prairies where heavy cattle grazing has
reduced the grass fuel load. Fires, which usually prevent blackjack oak
expansion, are cooler because of the reduced fuel load and not as
effective at killing woody species [23].
More info for the terms: fire suppression, prescribed fire
Many present-day post oak-blackjack oak stands were former savannas. In
the Wichita Forest Reserve in Oklahoma, the average age of stands
coincides with the advent of fire suppression in the reserve [13].
Forests may or may not revert back to savannas with prescribed burning
[23,58].
Prescribed fire, in conjunction with herbicides, may be
effective at eliminating blackjack oak [52]. Prescribed fire in 4-year
rotations may be effective at preventing blackjack oak expansion into
prairies [59].
Blackjack oak acorns are generally high in fat and low in protein.
