État de la populationExpert
There is no information available on a quantified population size, though Aizen and Patterson III (1990) report acorn production of Q. chapmanii is known to be high and frequent, as well as exhibiting the least variation in annual crop size. Since this species is known to be widespread and is abundant throughout its range, with high and frequent reproduction of acorns, it is assumed that the population size is high.

Description complète des menacesExpert
Quercus chapmanii occurs almost exclusively in Florida, although coastal scrubs extend into adjacent parts of Alabama and Georgia. Though there are no direct threats specific to the species itself, the quality of its habitat faces many threats. Being that scrub community is not particularly pleasing and sits on high and dry ground, this ecosystem and many of its species are rapidly being lost to development. Scrub is also readily damaged by off-road vehicle traffic or even foot traffic, which destroys the delicate ground cover and allows the loose sand to erode. Additionally, scrub is essentially a fire maintained community. Ground vegetation is extremely sparse and leaf fall is minimal, thus reducing the chance of frequent ground fires. Such fires allow for the regeneration of the scrub community which might otherwise succeed to xeric hammock communities.
