Visitor Guidelines & Policies
We encourage visitors to tour this lovely facility and researchers to utilize it. To ensure that staff is able to provide researchers and visitors with access to the herbarium, we recommend making an appointment. Of course you are always welcome to stop by and take your chances. First-time visitors wishing to use the herbarium must receive an orientation to the collections and specimen handling before access can be granted (less so for professional systematists).
Handling of Specimens
The specimens of the Yellowstone Herbarium are available for scientific study via loans to accredited institutions. Generally, loans are made for taxonomic or floristic research only, but exceptions may be made for other botanical investigations. A loan request must be in writing (emails are acceptable) from the researcher or curator of the institution where the specimens are to be shipped. It should be sent to Heidi Anderson, Park Botanist. The following information should be provided:
Loans of specimens are made for a period of six months. You may request an extension of the loan. While on loan, specimens must be housed in sealed herbarium cases and handled according to standard herbarium practices. We recognize that a limited amount of dissection may be necessary for some kinds of research. We request that dissections be kept to a minimum. All material dissected from a specimen must be placed in a fragment packed affixed to the sheet. Any need for destructive sampling (e.g., removal of seeds, pollen, DNA, etc.) is not generally allowed and would need to go thru a permit process. l
Did You Know?
You cannot fish from Fishing Bridge. Until 1973 this was a very popular fishing location since the bridge crossed the Yellowstone River above a cutthroat trout spawning area. It is now a popular place to observe fish.
