The understory contains plants such as Pacific yew, Pacific madrone, chinquapin, and vine maple. Underbrush consists of pinemat manzanita, greenleaf manzanita, tanoak, chinquapin, and snowbrush. Natchitoches means chinquapin eaters and Nacogdoches means persimmon eaters. The American Chestnut and American chinquapin are highly susceptible to chestnut blight. The dominant shrubs at the higher elevations are manzanita and bush chinquapin. So far it has not been observed on the Allegheny chinquapin ("C. pumila"). The chinquapin oak is especially known for its sweet and palatable acorns. As the elevation increases, there is a higher ratio of chinquapin to manzanita. Jeffrey pine, knobcone pine, and golden chinquapin have also been identified. There are currently no metrics available annotating the population of the actual community of Chinquapin. This trailhead is just south of Chinquapin and Glacier Point Road. Its two species have the common name chinquapin. A railroad depot was constructed in Chinquapin around 1916. It replaced the smaller Chinquapin Airport which was subsequently closed. The median age in Chinquapin was 45.4, significantly higher than the US median of 37.2.
