Production after 8 years ?
The article states: "Once established, the trees may start production as early as 8 years from seed and they will continue production for their lifespan."
- Production of seeds. These trees grow slowly and in a less than ideal location the tree can take decades to reach sexual maturity. --Una Smith (talk) 18:46, 22 December 2009 (UTC)
- Indeed, a forest of piñon pines produce seeds / cones all together, usually in cycles of four years or seven years. This is called "masting." They do not produce cones every year. Now and then a few confused trees will produce every second year, and some will produce cones every third year; unseasonably cool end-of-summers are thought to trigger masting events, but as far as I know that has not been established by studies. --Desertphile (talk) 00:41, 15 October 2013 (UTC)
- Spelling "piñon" and "pinyon" are both 100% correct. Various universities in the American Southwest use the "pinyon" spelling in their ecology papers, including University of Colorado and University of New Mexico. --Desertphile (talk) 00:37, 15 October 2013 (UTC)
- Just because it is in a couple papers does not mean it is correct. I am a physicist and I have read papers with errors in them, especially explosives-related papers from professors of universities. Academic papers are not fool-proof. And as the earlier poster said, you don't see any pages called jalapenyo. These wikipedia articles should be using the most used spelling (piñon) not some bastardized version of spanish (pinyon).188.8.131.52 (talk) 18:46, 20 February 2014 (UTC)
Human-caused Climate Change
Entire Pinyon Pine forests in northern New Mexico and southern Colorado are being wiped out by the human-caused increase in regional climates. New Mexico's Climate Division Two has seen a rise in temperature of about 1.2c in the past 50 years, and in some parts of Colorado the increase is almost 2c. Cone seed production has decreased by around 40% in the past 40 years, and huge sections of forests are dead and diseased. Perhaps someone can find the time to write a section in the article on the subject. --Desertphile (talk) 00:49, 15 October 2013 (UTC)
