The leaves ('needles') are, uniquely for a pine, usually single (not two or more in a fascicle, though trees with needles in pairs are found occasionally), stout, 4–6 cm (1 + 1 ⁄ 2 – 2 + 1 ⁄ 4 in) long, and grey-green to strongly glaucous blue-green, with stomata over the whole needle surface (and on both inner and outer surfaces of ...
Although in some sectors of landowners in the southeast learned over the years that the longleaf pine was a slow growing tree, and thus began replanting the ecosystem with faster growing trees species like slash and loblolly pines. With this replanting, faster tree growth and greater lumber production was achieved. [5]
Fire plays a key role in shortleaf pines ecology, fire influences their maintenance, structure, composition, regeneration, and establishment. Fire reduces competition with different tree species which increases shortleaf pine survival, and it also prepares the soil for regeneration. Shortleaf pine typically respond well to prescribed fire.

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.
Do you have a mature pine tree with bunches of brown needles? It may be suffering from a fungal disease called diplodia tip blight. “Diplodia has become more common due to environmental stress ...
Pinus torreyana is a broad, open-crowned pine tree growing to 8–17 meters (26–56 ft) tall in the wild, with 25–30 centimeters (9.8–11.8 in) long leaves ('needles') in groups of five. The cones are stout and heavy, typically 8–15 cm (3.1–5.9 in) long and broad, and contain large, hard-shelled, but edible, pine nuts. [4]
The maritime pine features the longest and most robust needles of all European pine species. [ 4 ] The cones are conic, 10–20 cm (4–8 in) long [ 4 ] and 4–6 cm ( 1 + 1 ⁄ 2 – 2 + 1 ⁄ 2 in) broad at the base when closed, green at first, ripening glossy red-brown when 24 months old.
