Abstract:

The digital availability of 400 or more years of herbarium collections would be a great benefit to both the public and scientists around the world; the development of this dataset is also a high priority to GBIF and NSF. However, to date, fewer than a dozen of the more than 3,000 herbaria around the world have had both the personnel and financial support to begin the process of digitizing their collections. Working with Rusty Russell, collections manager for the National Herbarium, we developed and tested two statistical models---an ANOVA and a linear regression---that indicated varying levels of collector overlap dependent on a combination of geographical specialty and size of an herbarium. The analyses indicated clusters of collector overlap and will be used to present a list of policy and financial support recommendations to both GBIF and NSF.
