![]() One individual of this species, dubbed " Methuselah", is one of the world's oldest living organisms at around 4,800 years old. The longest-lived is the Great Basin bristlecone pine ( P. longaeva). Pines are long lived and typically reach ages of 100–1,000 years, some even more. ![]() The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an 81.8 m (268 ft) tall ponderosa pine located in southern Oregon's Rogue River-Siskiyou National Forest. Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing 3–80 metres (10–260 feet) tall, with the majority of species reaching 15–45 m (50–150 ft) tall. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Pine may also refer to the lumber derived from pine trees it is one of the more extensively used types of lumber. Pines are commonly found in the Northern Hemisphere. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. The 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. Pinus is the sole genus in the subfamily Pinoideae. See list of pines by region for list of species by geographic distribution.Ī pine is any conifer tree or shrub in the genus Pinus ( / ˈ p iː n uː s/) of the family Pinaceae. 2006 Report on the Health of Colorado’s Forests – Special Issue: Lodgepole Pine Forests (2.6 MB PDF).See List of Pinus species for complete taxonomy to species level. 2008 Report: The Health of Colorado’s Forests – Special Issue: High Elevation Forests (9.5 MB PDF).ĢColorado State Forest Service.

Plant and animal diversity tends to be relatively low in lodgepole pine forests, but they do provide important cover for mule deer, elk, black bear and a variety of birds and small mammals. In the late 19th century, much of Colorado’s demand for railroad ties was supplied by lodgepole pine forests, which still provide a range of wood products, including house logs, structural lumber, log furniture, decking, telephone poles and structural plywood (CSFS 2006) 2. Lodgepole pine forests blanket many landscapes tied to Colorado’s water supply and provide the back-drop for popular recreational activities such as skiing, hiking and biking. These forests often are referred to as dog-hair stands. The prolific regeneration that naturally occurs in the open, sunny areas left in the fire’s wake often results in dense stands of 20,000 or more trees per acre. These long-lived cones may remain viable for decades, waiting for a fire to release their seeds. Lodgepole pine is intolerant to shade and thrives in the aftermath of fire many lodgepole produce serotinous cones, which open in response to extreme heat and release an abundance of seeds. Most of Colorado’s lodgepole pine forests developed following hot, stand-replacing crown fires (CSFS 2008) 1. Lodgepole pine forests grow and die uniformly. Lodgepole pine tolerates a wide variety of climatic and soil conditions, but achieves its best growth on gentle slopes and in basins with well-drained, slightly acidic, sandy or gravelling loams.
