A regional endemic threatened mainly by commercial exploita- tion and private gardeners. Few EO's of pure L. grayi and low abundance.
Overgrazing by cattle, herbivory by rabbits and European wild boars, habitat destruction, illegal collecting, low capsule production, canopy shading, and early senescence of flowering plants prior to capsule production.
Past research shows that anthr
61 extant populations in NC, some have only 5-10 plants. (Bates 2000)
Found in only one county in Tennessee. (Chester 1993)
Botanists for the Plant Conservation Program (PCP) are investigating the effects of clearing overstory on fungal infection and seed production. Preliminary results suggest that canopy clearing does not decrease early senescing but it may delay fungal infections. These data further suggest that plants with delayed fungal infection may have the opportunity to flower and produce capsules before wilting. Delaying the onset of fungal infection is one means of increasing capsule production (Bates 2000).
Continued monitoring and experimentation are being conducted by the PCP (see Bates 2000).
Some active management on protected lands (canopy clearing, cattle exclusion).
Unknown management on many private lands.
Protect existing populations and surrounding areas from development.
Continued research on fungal effects and early senescence.
Pollination biology, general ecological relationships.
Seed collection from all extant populations
