Disturbance response:
Fire: Chinkapin oaks grow in fire-prone environments such as gallery forests in riparian corridors on prairie margins as well as in closed-canopy forests. The fires in gallery forests were short interval (years) and likely low in intensity. Where fire is suppressed, succession to more shade-tolerant maple-basswood (Acer spp.-Tilia spp.) forests occurs. Chinkapin oak seedlings and saplings are susceptible to damage and topkilling, but as they grow larger they develop thick, smooth bark that is fire-resistant; few large trees are killed by typical fires. Fire-caused wounds can be entry points for damaging fungi and insects. When topkilled, chinkapin oaks readily sprout from the root crown or from root suckers. Seedlings sprout persistently if topkilled several times. Seedling establishment may occur from seeds of surviving trees onsite or from offsite seeds carried by birds and other animals. Like many upland oaks, chinkapin would be likely to increase in a regime of low-intensity, short-interval fire.
Exotics: Gypsy moth (Lymantria dispar) is a defoliator of eastern hardwood forests, introduced to Massachusetts from France in 1885. It has spread throughout New England into Virginia and Michigan. Defoliation causes growth loss, decline, and mortality. It feeds on many tree species, but Quercus and Populus are the most susceptible taxa, and trees growing on xeric sites are the most vulnerable. Various efforts have been made to control it, with mixed results. A fungus, Entomophaga maimaiga introduced from Japan causes considerable mortality to gypsy moth populations. E. maimaiga levels are promoted by damp weather.
