Fraser Fir
The she-balsam of the highest summits, a fir that grows wild only in the Southern Appalachians.
Summit trees in Mount Mitchell State Park, North Carolina. The trees in the frame are not identified, and a photograph of the fir itself is still to come.
- Scientific name

- NatureServe
- G2 (global rank)
- Documented in
- Black Mountains, Great Balsam Mountains, Great Smoky Mountains, Mount Mitchell, Roan Highlands, Roan Mountain

- Also called
- She-balsam, southern balsam. Red spruce, which grows with it, is the he-balsam.
- Form
- Evergreen tree to about 40 or 50 feet, with flat, soft needles rounded at the tip and cones that stand upright on the branch
- Range
- Southern Appalachian endemic, southwestern Virginia to southwestern North Carolina and adjacent Tennessee, mainly above 5,000 feet
- Habitat
- Tops and upper slopes of the highest peaks, in pure stands or mixed with red spruce
- Threat
- Balsam woolly adelgid, first found on Mount Mitchell in 1957
The tree
Fraser fir belongs to the highest ground. Vascular Plants of North Carolina calls it a Southern Appalachian endemic, ranging from southwestern Virginia into southwestern North Carolina and the edge of Tennessee beside it, mostly above 5,000 feet and often in solid stands above 6,000. It is a modest tree, forty or fifty feet at most, with a tidy, even crown. The needles are flat, soft and blunt at the tip, which tells it from the red spruce it grows among, and its cones stand upright on the branches.
The pair have long been called the he-balsam and the she-balsam, the fir being the she, and the Blue Ridge Parkway keeps the word at Richland Balsam. The Black Mountains are named for it too, by the North Carolina Gazetteer’s account, for the dark green of the fir on the summits. In North Carolina’s classification, as the state wildlife plan summarises it, Fraser Fir Forest is the community of the very highest peaks, where the fir is the only tree that survives in numbers.
The adelgid
The balsam woolly adelgid was first found on Mount Mitchell in 1957, by the Fish and Wildlife Service’s record. When Witter and Ragenovich measured the Mitchell stands in 1966, 82 percent of the larger fir stems in pure fir stands were dead, and more where spruce and hardwoods were mixed in. The Park Service says the insect reached the Smokies in the 1960s and has killed nine fir in ten there. On Mount Guyot, fir fell from 80 percent of the living canopy trees in 1967 to 2.5 percent in 1985.
The tree has held on. Plots on Mitchell resurveyed from 1986 to 2003 filled with young fir, dense and patchy, with the adelgid seldom found, though the researchers could not say what will happen when the new trees reach the size the insect attacks. Vascular Plants reports the species doing well on the Roan and on Grandfather and poorly in the Smokies and along the southern Parkway. Meanwhile, by Yancey County’s heritage plan, Christmas-tree plantations of Fraser fir cover the slopes below the range that carries the wild stands.
