Arabis perstellata
|
Arabis perstellata was named by E. L. Braun from plants collected between 1936 and 1939 on wooded hillsides along Elkhorn Creek in Franklin County, Kentucky. The plant is distinguished from other Arabis by the stellate (star-shaped) hairs on its stems and leaves. Braun's rockcress flowers from late March to early May, showing petals that range in color from white to lavender (Rollins 1960).

State Range
Habitat
| |
A. perstellata occurs on the slopes of calcareous mesophytic and sub-xeric forest types. It is sun intolerant and always occurs in at least partial shade. Plants are often found around rock outcrops, protected sites at the downslope side of tree bases, and sites of natural disturbance, such as talus slopes and animal trails. It is rarely found growing among the continuous herbaceous cover of the forest floor (USFWS 1995, 1997).
Species associated with A. perstellata: Saxifraga viriniensis, Sedum pulchellum, Arabis laevigata, Asplenium rhizophyllum (Jones 1991) |
Distribution

Three counties in Kentucky, associated with the Kentucky River drainage system (USFWS 1997). Two counties in Tennessee in the Stones River drainage and also along the Cumberland River (USFWS 1997). |
Number Left

Threats include habitat destruction, weedy competitors, trampling, logging, road work and grazing (Jones 1991; USFWS 1995, 1997). |
Current Research Summary
Current Management Summary
| |
A recovery plan has been written by the U.S. Fish and Wildlife Service, but no centralized plan has yet been implemented. |
Research Management Needs
| |
Management and research needs as outlined in the recovery plan (USFWS 1997) include locating new populations,
determining optimal habitat conditions, developing a site management strategy, developing a public education plan. |
Ex Situ Needs
| |
Secure and store viable seeds. |
