Taxonomic group specialists

Over the past four decades, the following individuals provided valuable contributions. Although, nearly 50% of the original contributors to my 1980 Checklist are now deceased or retired, I continue to honor them here by listing their names and associated areas of specialization. They, along with many others have improved BONAP’s efforts and assisted in building our international plant database.

Repositories visited by BONAP or from which plant materials and data have been exchanged

The following herbaria, museums, special collections and other repositories of vascular plants have been visited, consulted, or have provided valuable county-level records for our National Plant Atlas.

Field Botanists/Curators

The invaluable contributions of the following 384 individuals cannot be overstated. Tens of thousands of new county-level records have been added to the Atlas because of their collections. Equally important, thousands of erroneous reports have been eliminated. Although I have not always agreed with their conclusions, without their contributions, this Atlas would be hopelessly incomplete and far less accurate. I thank them all.

Photographic contributors

In the early 2000’s, I purchased a Nikon slide scanner and initiated a scanning campaign that has spanned ten years. Although the original scanner has been replaced twice, nearly 200,000 slides have been scanned. The vast majority of these slides were contributed generously by hundreds of individuals. BONAP’s current image collection contains nearly 300,000 images. Approximately, 100,000 of these are illustrated on our current websites, with the remaining 200,000 to be added later this year. Our goal is to provide quality images for all North American plant taxa as part of our North American Digital Flora and accompanying Floristic Synthesis software. We are extremely grateful to all who have willingly provided their images. Each contributor is credited here for his or her contributions.

WE WELCOME YOUR HELP. When assembling an image gallery this large, it is very easy to misidentify a plant or incorrectly link a scientific name to an image. Therefore, we welcome greatly any corrections. We shall soon include a list of plants for which we have no images or for which we need replacement images. If you would be willing to contribute photos, we would welcome them greatly. Please do not hesitate to contact us.
