The Flora of the PCT: C2 Cottonwood Trailhead to Whitewater Canyon: Plant Trail Order

See The Flora of the PCT: C2 Cottonwood Trailhead to Whitewater Canyon for an introduction to this checklist.

This version of the Checklist is in order of plants along the trail, from Cottonwood Trailhead to Whitewater Canyon, for the first 130 species in the list. Species that were not seen in the field survey, but which were vouchered from or near the trail, are given at the end of the list (marked with a V in the ID? column).

The plant trail order is not exact, because two different surveys, at different times of the year in different years, with different species visible in each survey, were merged to produce this list.

The column #Pls gives the minimum number of plants, up to a maximum of 99 plants, for species seen in the field survey on 8 January 2015. Species with RT in that column were seen only by RT and Shaun Hawke in a survey of the entire trail on 24 March 2013. No abundance estimates were made in those surveys. Species with V in that column were vouchered from the trail.

For species seen by us, an abbreviation is sometimes given just before the number of plants, to indicate uncertain determinations; see abbreviation for the determination uncertainties.
