Growing Volunteers Floristic Skills in our Region

The Geraldton Regional Herbarium group were the recipients of a grant from Western Australian State Natural Resource Program. This grant enables the herbarium to improve their identification and survey skills, collaborate with other community groups and engage with Traditional Owners for some two-way science.

The Herbarium is an important asset to the region. This collection of preserved flora represents the floristic diversity within the Midwest region. Lovingly collected, pressed, identified, labelled and stored, DBCA staff and herbarium volunteers spend many hours tending to this collection to keep it relevant and in good shape.

On Wednesday 18 and Thursday 19 August Botanist and orchid expert Andrew Brown led these passionate volunteers on their Eneabba field trip, sharing his knowledge and passion for of the incredible and unique Orchidaceae family and the species found in our region.

A total of 14 people from the Herbarium and the Jurien Bay Herbarium, Department of Biodiversity, Conservation and Attractions, MARP Rangers and NACC NRM all attended.

Volunteers are the backbone of the Herbarium and being able to get out into the field with expert guidance and knowledge is important. Many dedicated hours of work go into the collection and being able to provide training opportunities is both valuable and rewarding to the volunteers and herbarium collection.

This trip was particularly fantastic as we were able to collaborate across regions with volunteers attending from the Jurien Bay Herbarium group.
