In order to update an aging seed collection from 1988 and to contribute seed to the CPC IMLS seed longevity project, team members from NCBG collected approximately 2000 seeds of Geum geniculatum (bent avens). This species is only found at high elevations and is facing many threats including herbivory from deer, which we found extensively at this collection location. Herbivory greatly reduced the number of individuals with mature seeds as we found many plants with clipped stems. This collection was made possible through CPC and in cooperation with the US Forest Service.
In 2021, CPC contracted North Carolina Botanical Garden to recollect seed from a population currently held in long term orthodox seed storage as part of an IMLS-funded seed longevity experiment. The National Laboratory for Genetic Resources Preservation will evaluate how germination tested viability and RNA Integrity of seed lots decline over time in storage.
Restricted to high elevations in the southern Appalachians in northwest North Carolina and northeast Tennessee.?Locally abundant but known from only 4 populations covering 14 occurrences.
Disruption of hydrology as a result of development or logging.
There are 15 occurrences in North Carolina and 1 in Tennessee. High quality sites have thousands of individuals (Oakley 1991).
Little management is necessary. Informal monitoring is carried out by the North Carolina Natural Heritage Program and the Tennessee Ecological Services Division.
Much research is needed on this little known species beginning with basic life history studies. In addition, areas such as the effect of climate change should be investigated. The remnant populations of this plant persist in mountain refugia and may be unable to migrate or withstand global warming. Another sort of habitat change which requires research is hardwood canopy dieback. This is currently occurring in some high elevation forests in the Southern Appalachians. There are areas where this may affect populations of Bent Avens. The effect of this change should be studied. In addition, areas that have experienced canopy dieback may also experience encroachment by blackberries. Studies on how to best manage the blackberries may benefit the affected populations of Bent Avens. Further surveying of suitable habitat for possible populations may prove useful. This is especially important on Forest Service land being actively timbered (Oakley 1991).
