The herbaria foray locations we chose were based on Alberta Conservation Information Systems Management (ACIMS) data and the conservation status reports of spring 2015. Criteria for choosing foray locations included: species on wish lists from herbaria curators, previous occurrences, accessibility, conservation status, and phenology (species was identifable in June). Based on those criteria, the workshop committee chose Bertha Lake, Cameron Lake, Crandell Lake, Hay Barns, Ruby Ridge, Sofa Mountain, Waterton Townsite, and Wishbone Trail as good options to meet as many of the criteria as A. Scovil possible. Specimens were collected where occurrences met the best practice Alpine townsendia (Townsendia condensata Parry) S2. standards for collection (1 specimen per 50 plants) and would be distributed to Our plans to document rare species Based on the information submitted herbaria at the University of Alberta, were stymied a bit by the publication of about occurrences before the next major University of Calgary, Medicine Hat the ACIMS updated tracking and watch conservation status review, reviewers College, and Olds College.

Nevertheless, It is interesting to make note of a few we documented more than 50 vascular of the species we identifed whose species and 46 non-vascular species conservation status has improved since over the two-day foray. Nine of the the last major review of the tracking vascular species were ranked as S1 or S2 and watch list.
