Editing Torrey pine (section)

==Conservation==
There is some disagreement about the total population of ''Pinus torreyana''. In general, only the populations in [[Torrey Pines State Natural Reserve]] and on Santa Rosa Island are deemed to count as the wild population, not the trees planted around San Diego and wider California. In the 1970s it was estimated that the population in the TPSR and on Santa Rosa Island was about 9,000 individuals, but many of these trees have since died due to [[forest fire]]s, drought and a series of infestations of a [[bark beetle]], as well as being stressed by [[air pollution]]. There were only a hundred trees surviving in the early 20th century. As of 2016 it is thought by the California Native Plant Society that the population of this species is some 3,000 individuals.<ref name=TNCplantguide/> In 2011, [[Aljos Farjon]], assessing the conservation status of this species for the [[IUCN]], estimated that the total population of ''P. torreyana'' was 4,500 individuals. He states that there is a slow decline of the numbers, especially of the trees not found within the TPSR on the mainland.<ref name="iucn status 11 November 2021" />

The Torrey pine is protected by a city tree ordinance in [[Del Mar, California|Del Mar]], near the native habitat, and construction projects and citizens require a permit for its removal.<ref>{{cite web|url=http://www.delmar.ca.us/faq.aspx?qid=170 |title=How can I cut my tree down? |publisher=City of Del Mar |date= |accessdate=May 11, 2014}}</ref>
