Visitors & Volunteers


The Hodgdon Herbarium welcomes visiting scientists from other colleges and universities and federal, state, and private agencies. Those wishing to conduct research in the herbarium should contact the Collections Manager or curator beforehand to ensure access and availability of the facilities desired. All incoming specimens will be frozen before being allowed in the main collections room.

Tours and information sessions are offered for UNH classes, local schools, and other educational groups by appointment. Please contact the Collections Manager to make arrangements.


Those interested in volunteer opportunities should contact the Collections Manager. Typical tasks include specimen data entry, mounting and labeling, and scanning specimens for our Virtual Herbarium project. Volunteers with expertise in specimen identification are also welcome.
