Throughout the Appalachian Mountain range, P. pungens is a component of conifer-dominated communities along combination with other pine species. [10] The three tallest known Pinus pungens are in Paris Mountain State Park , South Carolina; they are 26.85 to 29.96 metres (88 ft 1 in to 98 ft 4 in) tall.
The longleaf pine ecosystem is a fire climax community, that is "a plant and animal community that is limited by and adapted to an early successional stage by frequent fire disturbances". [9] Fire destroys other pine species and hardwoods which would outcompete the longleaf pines.
Pinus ponderosa, commonly known as the ponderosa pine, [3] bull pine, blackjack pine, [4] western yellow-pine, [5] or filipinus pine, [6] is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.

He was later named the Herschel and Ruth Seder Professor of Biomedical Engineering, and was appointed by Johns Hopkins University President Ronald J. Daniels as one of 17 inaugural University Gilman Scholars in 2011. [6] [13] [14] In 2015, Miller became the co-director of the newly established Kavli Institute for Discovery Neuroscience. [15]
Pinus sabiniana trees typically grow to 11–14 metres (36–45 ft), but can reach 32 m (105 ft). The pine needles are in fascicles (bundles) of three, distinctively pale gray-green, sparse and drooping, and grow to 20–30 centimetres (8–12 in) in length.
Pinus rigida, the pitch pine, [2] [3] is a small-to-medium-sized pine. It is native to eastern North America , primarily from central Maine south to Georgia and as far west as Kentucky. It is found in environments which other species would find unsuitable for growth, such as acidic, sandy, and low-nutrient soils.
