Preservation and Storage

Herbarium specimens will last hundreds of years if properly cared for. We are committed to providing a secure and easily accessible collection for scientific research.


There is an art to the mounting of plant specimens to their archival quality cardstock backing. BRIT’s volunteers and staff participate in this activity daily.


Plant identification requires you have as much of the plant as possible, and in some occassions this cannot be accomplished if you are dealing with a sterile specimen.

Pressing and Drying

To facilitate specimen storage and use, collected plants must be pressed to a 2-dimensional status and dried to remove any moisture that would encourage fungal growth.
