Notes on Specimen Records and Images
Specimens are used for scientific research and because of skilled preparation and careful use they may last for hundreds of years. Some collections have specimens that were collected over 100 years ago that are no longer occur within the area. By making these specimens available on the web as images, their availability and value improves without an increase in inadvertent damage caused by use. Note that if you are considering making specimens, remember collecting normally requires permission of the landowner and, in the case of rare and endangered plants, additional permits may be required. It is best to coordinate such efforts with a regional institution that manages a publically accessible collection.
Statement on Offensive Content in Specimen Collections
The CCH acknowledges that, as historical specimens, herbarium specimen labels may contain offensive language. In the interests of historical integrity, we are not removing these words from occurrence records when they reflect locality information. We aim to include a flag on such records alongside these data that describes the currently accepted description or locality along with a reference to this Statement.
