Methuselah is a 4,856-year-old [1] Great Basin bristlecone pine (Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California. [2] [3] It is recognized as the non-clonal tree with the greatest confirmed age in the world. [4]
It was temporarily superseded by a 5,062 year old bristlecone pine discovered in 2010. In May 2017 however, Dr. Peter Brown removed this tree from his database of old trees because the tree and core sample could not be found. [8] "Methuselah" is not marked in the forest, to ensure added protection from vandals. [9]
Modoc National Forest was established as the Modoc Forest Reserve on November 29, 1904, by the United States General Land Office. It was named for the Modoc people who traditionally had their territory in this area. In 1905 federal forests were transferred to the U.S. Forest Service, and on March 4
Winds can be high throughout the year and are a major factor limiting plant growth near the upper limit of the subalpine zone (tree line). Wind limits vegetative growth chiefly in two ways: by physically battering plants, including blowing snow and ice, and by increasing evapotranspiration in an environment that is already water-stressed.

The flora of this ecoregion also includes tree species such as gray or foothill pine (Pinus sabiniana), scrub oak (Quercus dumosa), California buckeye (Aesculus californica), the rare Gowen cypress (Cupressus goveniana), the rare Monterey cypress (Cupressus macrocarpa), and a wealth of endemic plant species, including the extremely rare San ...
Coast Douglas-fir (Pseudotsuga menziesii ssp. menziesii) is the predominant tree, occupying up to 70% of the forest cover. Broadleaf evergreen trees are relatively few. Tree species of secondary importance are: Sugar pine (Pinus lambertiana), Ponderosa pine (Pinus ponderosa), White fir (Abies concolor).

Above the tree line, extreme winds preclude tree-like growth. [6]: 17 Constant winds hitting the plants limits their size and flattens their shape. [10]Small size or dwarfism is therefore an adaptive feature to the extremes, and most alpine plants are just a few inches tall.
