In 2002, North Cascades National Park (NOCA) contracted the WTU Herbarium to organize a series of plant collecting trips to generate vouchers of the park's flora. We have continued these trips each year since, and beginning in 2004 we expanded the trips to include Mount Rainier National Park (MORA) and Ebey's Landing National Historic Reserve on Whidbey Island.

Each year NOCA and WTU staff decide on collecting sites based on floristic richness or the lack of previous inventory work, then lead one or more 3-4 day collecting trips to those sites, with support from WTU volunteers. Specimen processing occurs at WTU, which includes making identifications, label making, and mounting over a period of several months following the collecting trip. Specimens in the field are collected in replicate, with the first set housed at the park herbarium, the second kept at WTU, and the third set generally sent to UBC.
