A pine is any conifer tree or shrub in the genus Pinus of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. World Flora Online, created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden, accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. Pine may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars recognized by the ACS. It is also a well-known type of Christmas tree.
Pine nuts, also called piñón, pinoli, pignoli, bondoq or chilgoza, are the edible seeds of pines. According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible but are too small to be of notable value as human food.
The pinyon or piñon pine group grows in southwestern North America, especially in New Mexico, Colorado, Arizona, and Utah. The trees yield edible nuts, which are a staple food of Native Americans, and widely eaten as a snack and as an ingredient in New Mexican cuisine. The name comes from the Spanish pino piñonero, a name used for both the American varieties and the stone pine common in Spain, which also produces edible nuts typical of Mediterranean cuisine. Harvesting techniques of the prehistoric American Indians are still used today to collect the pinyon seeds for personal use or for commercialization. The pinyon nut or seed is high in fats and calories.
Pinus brutia, commonly known as the Turkish pine and Calabrian pine, is a species of pine native to the eastern Mediterranean region. The bulk of its range is in Turkey, but certain varieties are naturalized as far east as Afghanistan. It is also known as East Mediterranean pine, Afghan pine, and Brutia pine. The name "Calabrian pine" comes from an introduced grove in the Calabria region of southern Italy; historically this region was called Bruttium, which is likely where the specific epithet "brutia" comes from. Pinus brutia bears many similarities with other, closely related species such as Pinus halepensis and Pinus canariensis. Turkish pine forms a species complex with the former.
Pinus cembroides, also known as pinyon pine, Mexican pinyon, Mexican nut pine, and Mexican stone pine, is a pine in the pinyon pine group, native to western North America. It grows in areas with low levels of rainfall and its range extends southwards from Arizona, Texas and New Mexico in the United States into Mexico. It typically grows at altitudes between 1,600 and 2,400 metres. It is a small pine growing to about 20 m (66 ft) with a trunk diameter of up to 50 cm (20 in). The seeds are large and form part of the diet of the Mexican jay and Abert's squirrel. They are also collected for human consumption, being the most widely used pine nut in Mexico. This is a common pine with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Pinus orizabensis, the Orizaba pinyon, is a pine in the pinyon pine group, endemic to central Mexico. It is considered also as a sub-species of Pinus cembroides which is classified as Pinus cembroides subsp. orizabensis D.K.Bailey. It has larger seeds than the type.
Pinus johannis, the Johann's pine, is a pine in the pinyon pine group, native to North America. The range extends from southeast Arizona and southwest New Mexico, United States, south in Mexico along the Sierra Madre Occidental and the Sierra Madre Oriental to southern Zacatecas and San Luis Potosí. It occurs at moderate to high altitudes, from 1,600–3,000 metres (5,200–9,800 ft), in cool, dry climate conditions.
Pinus culminicola, commonly known as Potosí pinyon or Potosí Piñón, is a pine in the pinyon pine group, native and endemic to northeast Mexico. The range is highly localised, confined to a small area of high summits in the northern Sierra Madre Oriental in Coahuila and Nuevo León, and only abundant on the highest peak, Cerro Potosí. It occurs at very high altitudes, from 3000–3700 m, in cool, moist subalpine climate conditions.
Pinus edulis, the Colorado pinyon, two-needle piñon, pinyon pine, or simply piñon, is a pine in the pinyon pine group whose ancestor was a member of the Madro-Tertiary Geoflora and is native to the United States.
Pinus monophylla, the single-leaf pinyon, is a pine in the pinyon pine group, native to North America. The range is in southernmost Idaho, western Utah, Arizona, southwest New Mexico, Nevada, eastern and southern California and northern Baja California.
Pinus quadrifolia, the Parry pinyon, is a pine in the pinyon pine group native to southernmost California in the United States and northern Baja California in Mexico, from 33° 30' N south to 30° 30' N. The Parry pinyon has a lifespan of around 200 to 500 years. It is usually found in rocky areas that often have thin soil. It occurs at moderate altitudes from 1,300 metres (4,300 ft) to 1,800 metres (5,900 ft), rarely as low as 1,200 metres (3,900 ft) and as high as 2,500 metres (8,200 ft). It is scarce and often scattered in this region, forming open woodlands, usually mixed with junipers. Other common names include nut pine and fourleaf pinyon pine.
Abert's squirrel or the tassel-eared squirrel is a tree squirrel in the genus Sciurus native to the southern Rocky Mountains from the United States to the northern Sierra Madre Occidental of Mexico, with concentrations found in Arizona, New Mexico, and southwestern Colorado. It is closely associated with, and largely confined to, mature ponderosa pine forests. It is named in honor of the American naturalist John James Abert; nine subspecies are recognised. It is recognizable by its tufted ears, gray color, pale underparts and rufous patch on the lower back. The squirrel feeds on the seeds and cones of the Mexican pinyon and the ponderosa pine when they are available, but will also take fungi, buds, bark, and carrion. Breeding normally occurs in summer, with a spherical nest being built high in the canopy.
Pinus maximartinezii, called Martinez pinyon, big-cone pinyon or maxipiñon, is a pine in the pinyon pine group, native to west-central Mexico.
The Sierra Madre Oriental pine–oak forests are a temperate broadleaf and mixed forest ecoregion of northeastern and Central Mexico, extending into the state of Texas in the United States.
Pinus nelsonii, Nelson's pinyon, is a species of pine native to the mountains of northeastern Mexico, in Nuevo León, San Luis Potosí and Tamaulipas at 1,800–3,200 m altitude.
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a biome found mid-elevations in arid regions of the Western United States, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates. At lower elevations, junipers often predominate and trees are spaced widely, bordering on and mingling with grassland or shrubland, but as elevation increases, pinyon pines become common and trees grow closer, forming denser canopies. Historically, pinyon-juniper woodland has provided a vital source of fuel and food for peoples of the American Southwest.
Quercus grisea, commonly known as the gray oak, shin oak or scrub oak, is a North American species deciduous or evergreen shrub or medium-sized tree in the white oak group. It is native to the mountains of the southwestern United States and northern Mexico. It hybridises with four other oak species where the ranges overlap, the Arizona white oak (Q. arizonica), the Gambel oak (Q. gambelii), the Mohr oak (Q. mohriana) and the sandpaper oak (Q. pungens).
The pinyon jay is a species of jay, and is the only member of the genus Gymnorhinus. Native to Western North America, the species ranges from central Oregon to northern Baja California, and eastward as far as western Oklahoma, though wanderers are often sighted beyond this range. It is typically found within foothills, especially where pinyon pines occur.
