Join noted botanist Paul Martin Brown and learn the skills necessary to develop a herbarium and help create a lasting record of the plants found at Tin Mountain’s 140-acre Rockwell Sanctuary in Albany. Participants will learn all of the necessary skills from searching and collecting to pressing and mounting plant specimens. This multi-session field study is ideal for families as there are tasks for those of all ages. Knowledge of local plants is helpful but not essential since participants will learn how to identify the plants as we progress with the summer-long project. The study group will meet every two weeks from late May through early October for sessions that will combine both field and lab work.  If your mobility is limited in the field, there is more than enough lab work to learn to keep you busy! There is something for everyone at all interest and knowledge levels.


Herbariums are collections of pressed and mounted plant specimens with informative labels that are used to study and produce a record of plants growing on a specific area, i.e., from a restricted tract of land to a whole state or country. A photograph is often used to accompany the plant specimen especially if it illustrates the plants well.  By carefully collecting and preserving plant parts that have the critical diagnostic features a reference also is constructed for learning about plant identifications, taxonomy.  The resulting herbarium will be stored at the Tin Mountain Nature Learning Center and will be used for years to come. Herbariums may last for many years if cared for properly; many have been around for over a century.


This is a hands-on class, not just a demonstration. Participants will be doing the actual searching, collecting, pressing, mounting, etc.  Each session will be 2-4 hours every two weeks with optional work days in between for those who can. Paul will be responsible for the identification of all plant specimens and will teach those who are interested in the techniques of keying out the specimens. By the end of the summer, participants should be able to identify most all plants common to woodlands and fields in the Mt. Washington Valley as well as several threatened and endangered species.


Paul Martin Brown is a summer resident of Acton, Maine and has spent more than 50 years exploring the wilds of New England and much of North America in search of rare plants. Many of his exploits have resulted in the publication of new species of orchids to science. Paul is a research associate at the University of Florida Herbarium at the Florida Museum of Natural History in Gainesville as well as the founder of the North American Native Orchid Alliance and the editor of the North American Native Orchid Journal.
