Phragmites
2
Phragmites, what are they? A wetland species found across the United States It is also known as a common reed
3
Phragmites Characteristics It can grow up to six meters high This plant is very long lived
4
Phragmites Leaves The leaves are defined as lanceolet –lanceolet means that they are longer than they are wide They are 20-40 cm long and 1-4 cm wide
5
Phragmites Flowers The flowers develop by mid summer They are arranges in spikelets Spikelets are very flat and very wide These flowers aid in reproduction

DifferencesBetweenNative&Non-NativeSpecies
11
Differences Between Native and Non-Native Location Native – Common across the U.S. Non-Native – Very common in the eastern states along the Atlantic Ocean and spreading across much of the Midwest and in parts of the Pacific Northwest
12
Differences Between Native and Non-Native Leave Sheaths Native – fall off in the fall and they are very easily removed if they do stay on the stem Non-Native – the leaf sheaths stay on the plant. They are difficult to remove. But can be by using a twisting motion.
13
Differences Between Native and Non-Native Stem color at base (spring/summer) Native – Appears to be red to chestnut in color Non-Native – Appears to be tan or brownish in color
14
Phragmite – Native Stem During Spring/Summer
15
Differences Between Native and Non-Native Stem color at base (winter) Native – light chestnut to light brown or gray
16
Differences Between Native and Non-Native Stem color at base (winter) Non-Native – Tan in color
17
Differences Between Native and Non-Native Stem Texture Native – Smooth and shiny, it looks polished Non-Native – Rough and dull, the stems are ribbed, the ridges are visible with the naked eye

26
Reproduction in Phragmites
27
Can reproduce by seeds Can reproduce asexually by means of rhizomes
28
Reproduction in Phragmites What are rhizomes? - horizontal, usually underground stem of a plant that often sends out roots and shoots from its nodes
29
Reproduction in Phragmites Temperature, Salinity and water levels can affect seed germination Germination means to cause to grow or sprout Germination will increase with increasing temperature between 16 o C to 25 o C
30
Reproduction in Phragmites Germination is not affected by salinities below 10 parts per million (1%) but it does decline at higher salinities Water depths of more than 5 cm and salinities above 20 parts per million (2%) prevent germination Phragmites - Reproduction GTUEYMCRSHBSYCXQGMFMPCSNG AELVDHDNEUDORIWHVYYQNHDTJ KCRGXUCVMKTDGZXBKBEDAYOWD UVAMDQVTOBWLGWWPMFWRFMDAE WGUSIZXAZNJTZOOJTMHYAAXQF TETSFNANIODYXHXKVVHLLBPTA FWUIWJAJHNTKETMGUMTOAUISD AESSSDPTRWJLAXNAKDULAPTRI TGRXNROFICSFJQSJPGBDJSJJS DBTJBXNLXOMSEENTUJQKGFBTQ CJXAFJOFFMNCXOCPRTDKRWSQL LPIRFIILUXJUBTRFEKHNNACHS ESPTPFTFCLAKQZMMIYAOSSXVI CEECRACDDLZARDPIGKVUAOPZH FLRCNMUPLISFPEWWOUZLRYOZX WLXSTRDYNFQLRIFLIMIHVOUJV AFBXLDOANNJAEZPNBNLFIBCHA HACDRURTYVTOKVGJIZNECOXCO YPNPACPCYUUKMIETOVNNDSAXU OFDWKAECRAEFBQYLVXGMFJMML ZZBNPXREICZLURPURITRXEOIY MVFKVVHCEUTZYKJJOEPXJZSDG DNIFXPHGNWKDNFPDXDTMPKHQW UQGHXJDOMTUHNKUUUQKAGMGPB LLYHGCHOSCGDWCBISOVXWSUVA ASEXUALLYGERMINATIONREPRODUCTION RHIZOMESSALINITYTEMPERATURE WATER-LEVELS

HistoryofPhragmites
32
History of Phragmites During the 1900’s rapidly spread and invaded fresh and brackish wetlands. These plants altered the landscape of the marsh-estuary system
33
History of Phragmites The expansion may have been caused by human activity These human activities may have led to habitat destruction, sedimentation and decreased oxygen levels in water and sediment in marsh areas
34
History of Phragmites How These Plants Can Be Used Feed for cattle and horses Building dwellings, lattice, fences Arrows by Indians Weaving for mats and carrying nets Pulps for rayon and paper Pens for writing on parchment Rope Making
35
History of Phragmites How These Plants Can Be Used Thatching, making baskets and sandals Brooms Medicine
36
History of Phragmites How These Plants Can Be Used in Medicine This plant has been used in folk remedies for: LeukemiaBronchitisCancerCoughDiabetes
