Albrecht, M.A., and McCarthy, B.C. 2006. Comparative analysis of 
goldenseal (Hydrastis canadensis L.) population re-growth following
        human harvest: implications for conservation. The American Midland 
Naturalist 156(2):229-236.

Main findings:

1) Goldenseal populations wild-harvested in West Virginia and Ohio 
regenerated at different rates

2) Data do SUGGEST, however, that fall harvested populations may recover 
in 
population size and structure at greater rates than summer harvested 
populations

3) We need WAY more data to draw stronger conclusions on goldenseal 
population re-growth rates

4) Need participatory research with harvesters in order to understand how 
harvesters manage wild populations through selective and differential 
digging.
