P. radiata is a coniferous evergreen tree growing to {{convert|15|-|30|m|-1|abbr=on}} tall in the wild, but up to {{convert|60|m|abbr=on}} in cultivation in optimum conditions, with upward pointing branches and a rounded top. The leaves ("needles") are bright green, in clusters of three (two in var. binata), slender, {{convert|8|-|15|cm|frac=2|abbr=on}} long and with a blunt tip. The ovulate cones are {{convert|7|-|17|cm|in|frac=2|abbr=on}} long, brown, ovoid (egg-shaped), and usually set asymmetrically on a branch, attached at an oblique angle. The bark is fissured and dark grey to brown. When not cut short by disease or harvesting, it has a lifespan of 80 to 90 years.{{Citation needed|date=April 2021}}

The specific epithet radiata refers to the cracks which radiate from the umbo of the cone scales.

It is closely related to bishop pine and knobcone pine, hybridizing readily with both species; it is distinguished from the former by needles in threes (not pairs), and from both by the cones not having a sharp spine on the scales.{{Citation needed|date=April 2021}}

The modern tree is vastly different from the native tree of Monterey.{{cite book|last1=Powell|first1=Leslie|title=The Genus Pinus: A Reference Guide for Pines|date=9 February 2017|publisher=lulu.com|isbn=978-1365157172|page=112}}{{self-published source|date=April 2021}}{{self-published inline|date=February 2020}} In plantations the tree is commonly planted at 4 square meter spacing on a wide variety of landscapes from flat to moderately steep hills. Because of selective breeding and more recently the extensive use of growth factor seedlings, forests planted since the 1990s have very straight tall trunks without the problem of twin leaders. The trees are pruned in three lifts so that the lower two-thirds of a mature tree is free of branches and hence of knots.

In the United States, it is native to three very limited areas located in Santa Cruz, Monterey, and San Luis Obispo Counties of California.{{cite web|url=https://www.fs.usda.gov/database/feis/plants/tree/pinrad/all.html#DISTRIBUTION%20AND%20OCCURRENCE|title=Pinus radiata|work=Fire Effects Information System|publisher=US Forest Service|access-date=2023-09-24|year=1993|first=Amy B|last=Cope}}

In Mexico, it is found on two islands in the Pacific Ocean, Guadalupe Island and Cedros Island. On Guadalupe Island, located {{Cvt|280|km|nmi|round=5}} off the mainland coast, the pines are found on the steep northern end of the island, at elevations of around {{Cvt|500|to|1200|m}}, where they follow the ridgetops and steep slopes. On Cedros Island, the pines are more abundant, being found in far greater numbers partly due to the lack of feral goats. They are found at lower elevations than on Guadalupe, at around {{Cvt|285|to|690|m}}, on the windward ridges and canyons of the north and central parts of the island. In both cases, the pines seem to be heavily dependent on locations with a high frequency of fog.{{Citation |last1=Rogers |first1=Deborah L. |title=Conserving the Pines of Guadalupe and Cedros Islands, Mexico: An International Collaboration |date=2005 |url=https://doi.org/10.1007/1-4020-3774-0_2 |work=Environmental Issues in Latin America and the Caribbean |pages=31–54 |editor-last=Romero |editor-first=Aldemaro |place=Dordrecht |publisher=Springer Netherlands |language=en |doi=10.1007/1-4020-3774-0_2 |isbn=978-1-4020-3774-0 |access-date=2022-07-21 |last2=Jesús Vargas Hernández |first2=J. |last3=Matheson |first3=A.

In Australia, New Zealand, and Spain it is the leading introduced treeScott, C. W. 1960. Pinus radiata. Food and Agriculture Organization of the United Nations, Forestry and Forest Products Study 14. Rome, Italy. 328 p. cited in {{harvnb|McDonald|Laacke|1990}}. and in Argentina, Chile, Uruguay, Kenya, and South Africa it is a major plantation species. It is also an introduced tree on the world's most remote inhabited island, Tristan da Cunha.{{Citation needed|date=April 2021}}

Two varieties of this species have been recognized, each corresponding to the island they are endemic to in Baja California. Some authors lump these taxa and do not recognize infraspecies.{{Cite journal |last1=Rebman |first1=J.

On both islands it is the only pine species, and one of the few tree species. Compared to the mainland species, which are mostly three-needled, the insular varieties have their needles in bundles of two. Their cones are also smaller, and they show greater wind resistance in regards to wind-induced toppling.

P. radiata is adapted to cope with stand-killing fire disturbance. Its cones are serotinous, i.e. they remain closed until opened by the heat of a forest fire; the abundant seeds are then discharged to regenerate on the burned forest floor. The cones may also burst open in hot weather.{{cite book|last=Little|first=Elbert L. Jr.|year=1980|title=The Audubon Society field guide to North American trees|location=New York|publisher=Alfred A.

In its native range, P. radiata is associated with characteristic flora and fauna. It is the co-dominant canopy tree, together with Cupressus macrocarpa, which also naturally occurs only in coastal Monterey County.{{cite web |url=http://www.globaltwitcher.com/artspec_information.asp?thingid=62524 |title=Monterey Cypress (Cupressus macrocarpa) |last1=Hogan |first1=C.

The habitat of the pines on Cedros Island contrasts greatly with the desert scrub on other parts of the island, forming zones of abrupt transition. The numerous groves form a mostly-monotypic forest of the species, with very few other plants besides seedlings emerging in the understory. In some areas, the edges of the forest form a zone that supports chaparral species, including Malosma laurina, Diplacus stellatus, and the endemic Eriogonum molle. With their large surfaces to condense fog, the pines create irrigation for themselves and their associates. Towards the far northern end of the island, a succulent community mostly consisting of Dudleya is found, and the endemic Dudleya pachyphytum can sometimes be found growing under the pines in the ecotone.{{Cite journal |last=Oberbauer |first=Thomas A. |date=1987 |title=Floristic Analysis of Vegetation Communities on Isla de Cedros, Baja California, Mexico |url=https://www.researchgate.net/publication/281823533 |journal=Third California Islands Symposium |pages=115–131}}

In South Africa, the tree is a threat to already scarce water resources.{{Cite book|title = Wild Hope|last = Balmford|first = Andrew|publisher = University of Chicago Press|year = 2012}} The tree has remarkable roots. Monterey pine roots will reach downward as far as physically permitted by subterranean conditions. Roots have been discovered up to {{convert|12|m|sp=us}} long.{{sfn|McDonald|Laacke|1990}} Efforts to remove large quantities of the non-native tree in areas of South Africa have resulted in significant increases in accessible water.

The three remaining wild stands of var. radiata (Monterey pine proper) are infected and under threat of extirpation from pine pitch canker caused by Fusarium circinatum, a fungal disease native to the southeast United States and found (in 1986) to have been introduced to California. When trees decay due to the disease, they attract bark beetles which provide a pathway for infection of other trees. In some stands, 80–90% of trees are infected. If the disease is introduced in agroforestry areas dependent upon P. radiata, such as New Zealand, it could have catastrophic effects in those countries as well.

Sphaeropsis blight (Diplodia pinea) infects P. radiata in California and causes serious damage to plantations of the species in New Zealand, Australia and South Africa,{{cite web |url=http://www.na.fs.fed.us/spfo/pubs/fidls/diplodia/diplodiafidl.htm |title=Diplodia Blight of Pines |work=Forest Insect & Disease Leaflet 161 |publisher=Northeastern Area State and Private Forestry |archive-url=https://web.archive.org/web/20161016045741/http://www.na.fs.fed.us/spfo/pubs/fidls/diplodia/diplodiafidl.htm |archive-date=16 October 2016 |access-date=5 March 2015 |url-status=live}} especially after hail damage to growing tips.{{Citation needed|date=April 2021}}

On Guadalupe Island, var. binata is critically endangered. Most of the population was destroyed as tens of thousands of feral goats ate binata seedlings and caused soil erosion from the mid-19th century until just a few years ago.{{when?|date=January 2024}} The older trees gradually died off until by 2001–2002 the population stood at only one hundred. With a program to remove the goats essentially complete by 2005, hundreds of young Guadalupe pines have started to grow up in habitat fenced after 2001, the first significant new growth in about 150 years. Possible accidental introduction of pine pitch canker is considered the biggest threat at present to the survival of the Guadalupe Island pine population.{{cite conference |last1=Junak |first1=S |last2=Keitt |first2=B |last3=Tershy |first3=B |last4=Croll |first4=D |last5=Sánchez |first5=JA |date=13–14 November 2003 |title=Recent conservation efforts and current status of the flora of Guadalupe Island, Baja California, Mexico |url=http://www.ine.gob.mx/ueajei/publicaciones/libros/477/abstracts.html |conference=Taller sobre la Restauración y Conservación de Isla Guadalupe [Workshop on restoration and conservation of Guadalupe Island] |publisher=Instituto Nacional de Ecología |archive-url=https://archive.today/20120804024732/http://www2.ine.gob.mx/publicaciones/libros/477/abstracts.html |archive-date=2012-08-04}} The University of California's Russell Reservation forestry research station hosts an orchard planted with 73 P. radiata seedlings from Guadalupe Island and plays an important role in conserving the binata variety.{{cite web |last=Rogers |first=Deborah L. |title=Status of Conservation of Monterey Pine |url=http://www.grcp.ucdavis.edu/publications/doc26/Chapt4.pdf |location=Davis, CA |publisher=University of California |access-date=17 March 2012 |url-status=dead |archive-url=https://web.archive.org/web/20100610164828/http://www.grcp.ucdavis.edu/publications/doc26/Chapt4.pdf |archive-date=2010-06-10}}

P. radiata is widely used in private gardens and public landscapes in temperate California, and similar climates around the world. It is particularly commonly grown as a landscape tree in coastal areas of California outside of its native range, where the climate is virtually identical to its native range. It is fast-growing and adaptable to a broad range of soil types and climates, though it does not tolerate temperatures below about {{convert|-15|C}}. Its fast growth makes it ideal for landscapes and forestry; in a good situation, P. radiata can reach its full height in 40 years or so. Though a combination of biotic and abiotic factors determines the natural distribution of P. radiata, humans have broadly expanded its distribution up and down the California coast, even reaching Oregon.{{Cite web|last=George|first=Zach St|title=The Tree That's Rare, Endangered and Common – Bay Nature Magazine|url=https://baynature.org/article/the-tree-thats-rare-endangered-and-common/|access-date=2020-11-14|website=Bay Nature|language=en-US}}
