The following list started wih a list based on collections made July 6, 1998, by Yory Allred, Alicia Blaakman, George Falk, Jennifer Hart, and Tina Mensing in partical fulfillment of the requirements of Botany 2410.  Their identifications were verified by Barkworth and will be deposited in the Intermountain Herbarium..  The list has been supplemented by specimens in the herbarium database that have the phrase "Preston Valley" in the locality field and observations (alas, not vouchered) by participants of field trips made on May 20 and June 12, 2004.

The Preston Valley trail starts at 41º 46'N, 111º 44'W or, in road map terms, 3 miles east of the entrance to Cache National Forest from Green Canyon (which is reached by going east on 19th North from 16th West, North Logan) and heads up a basically north-facing slope to the ridge between Green and Logan Canyons.   The trail zigs and zags, resulting in a multitude of different habitats.  It is also crossed in its lower reaches by a small stream that by early summer has become simply a damp, shady draw. The base of the trail is dominated by Acer grandidentatum but as it moves upward and twists to a more an eastern exposure the vegetation becomes more open with Cercocarpus montanus and Artemisa tridentata. Further up, Pseudotsuga menziesii dominates on north facing slopes and in the draws.
