Students, staff, herbarium affiliates, and visitors regularly utilize the herbarium collection for a variety of research purposes. Current projects include family treatments for a new state flora (in conjunction with UW-Madison), research on DNA barcoding of sedges and orchid seed micromorphology, and the development a checklist for the Treehaven property. Around a dozen students currently work in the UWSP herbarium, some as paid employees and others for academic credit. We have around 190,000 catalogued specimens in the vascular plant collection, around 40,000 bryophyte specimens, and several hundred fungi and lichen specimens. We also maintain an accessory collection of dried fruit, seed, and cone structures.
