Rank Reasons
Aconitum reclinatum is a perennial herb that is endemic to the Appalachian Mountains of southwestern Pennsylvania to West Virginia, Virginia, North Carolina in the eastern United States. There are likely 150 or more occurrences. Primary threats to the species include the alteration of wetlands, intensive logging or clearcutting, and deer browse.
Range Extent Comments
Aconitum reclinatum occurs in the eastern United States, where it is endemic to the Appalachian Mountains of southwestern Pennsylvania, Tennessee, West Virginia, Virginia, and North Carolina (Weakley 2020). It has also been reported from Georgia, but it has never been verified and all known reports of A. reclinatum are A. uncinatum (T. Patrick, pers. comm., 1995)).
Occurrences Comments
There are 54 occurrences in North Carolina, 3 in Pennsylvania (including 1 historical), 1 in Tennessee, 50 in Virginia, and 60 in West Virginia.
Threat Impact Comments
This species may require maintenance of seepage habitat in low-elevation sites. Draining and filling of wetlands are the primary threats for this species. Logging may pose a threat by causing physical disturbances to the soil and habitat. Deer browse is a threat. Excessive grazing and trampling may cause soil compaction, resulting in low vigor, poor germination and poor seedling development. Recreational vehicles (ATV, motorcycles, etc.) and hiking traffic are threats. In Pennsylvania a fungus has been found that destroys the flower stem before the fruit sets, then eventually rots the plant, leaving only roots (K. McKenna, pers. comm., 1995).
Ecology & Habitat

Diagnostic Characteristics

Perianth usually white, upper sepal elongate-conic, about twice as high as long; rachis and pedicels strigulose, the hairs short, stiff, incurved; roots fascicled slender.

Habitat

This specie occurs in rich, mixed forests in the mountains at high elevations and is often found along streams, in coves, seeps or other moist areas. Virginia notes this species in deep mountain ravines and on greenstone (C. Ludwig 1995). North Carolina reports many occurrences from moist cove forests.

Ecology

In Pennsylvania, A. reclinatum is uncommon, with only two extant sites. Areas have moist soil (one is a seep, the other a valley bottom). Sites are forested, although they have been logged. The most recently logged site has improved from approximately five plants in 1978 to over 55 clumps in 1986. The second site has several colonies, totaling approximately 100 plants in 1993. The long-term effect of logging is unknown. (Pennsylvania Natural Heritage Program, 1995)

A. reclinatum appears secure in Virginia with well over 50 sites in the mountains. It is often found in deep mountain ravines, on greenstone or other rich substrate (Ludwig, C. 1995).

This species also appears secure in North Carolina. Several populations have thousands of plants (a few with tens of thousands). Most are found in rich forested coves, seeps, streambanks, and moist boulderfields. (North Carolina Natural Heritage Program, 1995).

In West Virginia most populations are small (5-10 plants), but a few are larger with approximately 50 plants (one site has over 200). Since its habitat is fairly common in West Virginia, it is probably more abundant than the data show, with several undocumented sites. It is found in the higher elevations, mostly at streamsides or in seeps and almost exclusively on Cateache soils with Mauch Chunk geology (Concannon, J., 1996). One plant was found at a cave exit in the cool air drainage. Other occurrences are on disturbed land where seeps and coves meet roadcuts.

According to Hardin (1964), species may be vulnerable to habitat disturbance.
