Blue ridge goldenrod is a perennial plant endemic to a very narrow range found on rock outcrops, cliffs, and balds in the Blue Ridge Mountains of North Carolina and eastern Tennessee. Solidago spithamaea grows from short stout rhizomes while erect stem is from 5-10 cm. tall and is usually unbranched below the inflorescence. It is known from only three populations and is Federally listed as threatened but State listed as endangered in both North Carolina and Tennessee. It is considered to be a relict a larger group of goldenrods abundant in more northern, alpine localities. The rock outcrops on which it occurs are exposed with no canopy cover and experience possibly the most extreme winter conditions in North Carolina and Tennessee (Sutter 1986). It is these open mountain summits that have been commercially developed, with the construction of observation platforms, trails, parking lots, roads, etc. that have directly impacted populations of this species, and the visitors who use these resorts often indirectly contribute to population decline.

Confined to small areas on a few very high, rocky summits in the Blue Ridge Mountains in North Carolina and Tennessee. There are 5 populations currently known to exist in NC. 4 of those populations are protected. Another 3 historical populations were extirpated by extensive recreational and residential development. However, the largest population currently known is thriving despite heavy recreational use of the site.

Three populations are known, and the largest of these is thriving despite heavy recreational use (NatureServe 2001). Approximately 2000 plants were known when the Recovery Plan was written (USFWS 1987).

Further study is needed in a number of areas, including: Specific management requirements Demographic studies of each population Pollination biology Seed dispersal Roles of biotic and abiotic environmental factors and disturbance on plant and population vigor The potential effects of acid precipitation Management needs include Searches for additional populations Implementation of management requirements when determined

Rock outcrops, cliffs, balds, and ledges, generally at elevations higher than 4600 ft. (USFWS 1987)Often associated with another rare, endangered endemic, Liatris helleri, as well as Picea rubens, Geum radiatum, Scipus cespitosus, and Leiophyllum buxifolium (Sutter 1986, NatureServe 2001).

Ecological Relationships

The Blue Ridge goldenrod is considered to be one of the few southern representatives of a larger group of colder-climate, alpine goldenrods abundant in the northern US (USFWS 1987) . The Blue Ridge goldenrod populations probably occupied a much larger range and were continuous with the now northern species when the climate was cooler and moister. With the recession of the glaciers and the consequent warming and drying of the climate, the Blue Ridge goldenrod was relegated to the most alpine-like conditions in the Southern US. The plant flowers from July to September and reproduces by rhizomes and seeds. (Sutter 1986, NatureServe 2001).
