June 7, 2012 looking mainly into Tooele County, Utah.While there is also a native strain, these plants represent the invasive strain. Both were previously recognized taxonomically as Phragmites australis* (which goes to show just how important genotypes are, i.e. the seeds from the same "species" are not simply the same) but the invasive strain as depicted here (which has bushier seed heads and darker leaves that are more persistent and lower exposed culms that are not reddish in fall) is subsp. australis (and the native subtaxon is subsp. americanus).

The native subspecies Phragmites australis subsp. americanus has much larger glumes than the invasive strain.April 12, 2013, along the Colorado River in Grand County, Utah, elev. 4010 ft. (1220 m).

In the center, note the native stand of "common" reed with the reddish stems and green but not dark green leaves. This is the native subspecies, Phragmites australis subsp. americanus (and so not the strain that we hear so much in the news about that is being fought along the Wasatch Front especially around Utah Lake and the Great Salt Lake and along the Jordan River, etc.). It is thick and grows tall, but is not as overpowering as the invasive strain.Native stands of this tall grass species are now rarely encountered in northern Utah; the native subspecies has now been largely supplanted by the invasive form.October 22, 2010, Sandy, near base of Little Cottonwood Canyon, Salt Lake County, Utah, at about 5570 ft. elev.

A small stand of the native Phragmites australis subsp. americanus. Reddish coloration of new culm growth can be seen. The native subspecies can still be thick in places but isn't as dense as its non-native counterpart (you could easily walk through it; the invasive strain is typically quite difficult to traverse).April 12, 2013, along the Colorado River in Grand County, Utah, elev. 4010 ft. (1220 m).
