General Research Observations
Taxon: Phragmites australis subsp. americanus Saltonstall, P. M. Peterson & Soreng
Family: Poaceae
Collector: Frates, Tony   20180922040   
Date: 2018-09-22
Locality: USA, Utah, Summit, Three Mile Canyon Rd. approx. 0.2 miles south of Utah State Route 32 (which here parallels Rockport Reservoir) in drainage
40.758512  -111.39453 +-10m.  WGS84
Elevation: 1840 meters (6035ft)
Habitat: High water level of a vernally flooded canyon drainage
Description: Initially I placed this under subsp. australis however a closer look at the base of the stems indicates they are reddish; so this may in fact be a native stand
Reproductive Condition: Fruiting
Occurrence Remarks: Plants are growing along a natural canyon drainage which artificially backs up and floods this area earlier in the year as a result of it being blocked off by state route 32. Most of the plants are growing on the east side of the drainage, but there are also a few on the west side. Plants were only viewed from a distance so a closer inspection is needed to verify that they are the invasive subspecies; based on their growth habit and stem color, they appear to likely be the invasive strain.
