Volunteers are an integral part of the Botany department. The Botany department has a large and diverse group of volunteers who we rely on in the field and in the herbarium. Volunteers are responsible for mounting plant specimens, databasing, filing, field work and numerous special projects depending on skill level and background.
At this time, the department is not accepting new volunteers.
