National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Recovery Plan for Small-anthered Bittercress (Caramine micranthere Rollins.)

PB2010112652

Publication Date	1991
Personal Author	Murdock, N.; Weakley, A.
Page Count	27
Abstract	Current Species Status: Cardamine micranthera is listed as endangered. There are 9 Populations remaining, all within North Carolina and Virginia; 12 sites have been destroyed. Most of the surviving populations are small, and many have been adversely altered by impoundments; channelization; and residential industrial, and agricultural development. None of the populations are permanently protected. Aggressive exotic weeds threaten all populations. Habitat requirements and limiting Factors: This small perennial herb is native to small streambank seeps, adjacent sandbars, and stream edges in the Dan River drainage of the North Carolina and Virginia piedmont. Most of the remaining populations are extremely samll (some containing less than half a dozen plants). Many are in close proximity to fields and pastures, where they are vulnerable to herbicides, erosion, and siltation. More research on management and the biological requirements of small-antherd bittercress is needed. Recovery objective: Delisting. Recovery Criteria; Six self-sustaining populations myst be permanently protected. Actions Needed: 1. Survey suitable habitat for adiitional populations. 2. Monitor and protect existing populations. 3. Conduct research on the biology of ths species. 4. Establish new populations or rehabilitate marginal populations to the point where they are self-sustaining. 4. Investigate and conduct necessary management activities at all key sites.
