Can you tell where we stopped spraying?

I was taking a walk

And I took these pictures of some gulls ,cordgrass , Phragmites, and the Hackensack river

My husband requested a series of invasive species for his shirts. First up - Common Reed (Phragmites)

Spooky Season

[kyotodreamtrips]

The autumn festival at Misu Shrine in Fushimi-ku, Kyoto City, is held on the second Sunday night of October. In the autumn of the previous year, we harvested the reeds with ears from the reeds (葭-yoshi) that grow naturally in the Uji River and made a large torch fire. The large torch, bundled in layers, is about 1.2 metres in diameter, about 4 metres in length, and weighs about 1 ton. The large torch cannot be moved while standing, so it is laid on the side and carried by 32 men.

Ok y'all I have promised my beloved mutual @pop-squeak that I would write a post on my most beloved invasive marsh plant, Phragmites australis also known as the common reed. This thing is so invasive that it is considered a model for invasive plants as a whole.

Some things before we start

Most of this is focused on Virginia since that's where a lot of the research on this bad boy is being done but it does exist elsewhere

I will have citations at the end if you want some more reading

This is based on research I did for a paper like a year ago so there might be new research I am unaware of due to having other classes to do

Please brush off your shoes when you enter/ leave a park so you don't bring stuff places it shouldn't be

Please read I promise it is really really interesting and important to the resilience of out coasts in North America especially in the mid Atlantic to the south :)

If you have questions don't be scared to drop them in the replies/ reblogs

I am an undergrad!!!!! I am generally new at this but I am fairly familiar with this specific subject and trust that everything in this post is accurate, but in general with invasive species it is a heavily nuanced topic that can be very complex. This is my best attempt to simplify this species for general consumption since I think its just really cool and important to coastal botany rn.

This thing lives in the marsh which is the area often between forest and the ocean/ body of water of varying salinity. This thing loves moderate salinity marshes since it can somewhat resist salt water intrusion. This is a part of what makes it so invasive especially in this era of severe sea level rise. Many coastal forests are dying as sea level is rising pushing the marsh farther inland. Part of the problem is that many native species can not move as colonize the new land as fast as the common reed can.

Phragmites as is incredibly good at reproducing and growing so close together that nothing else can live even close to it. It makes clonal offshoots of itself (THEY CREATE CLONES OF THEMSELVES?!?!?!?!?) and creates networks for communication. this dense packing leads to a monoculture where for miles in the strip of marsh 95% of what you see is phragmites. It is a magnificent and horrifying sight as you see the dead trees in the middle of these fields of phragmites knowing it was only 5-10 years ago that that was where the forest line was. It is the beautiful horror about being slowly consumed by the ocean. This monoculture does not only apply to flora but also fauna.

Farmers often actually welcome phragmites to their land and are resistant to get rid of it. This is because as native species have died off, phragmites has been able to colonize these areas fast enough to help resist further salt inundation and prevent flooding. This unfortunately is only a band-aid solution, especially in southern Virginia near the Chesapeake bay which has some of the highest rate of sea level rise in the country, since native plants and diverse marshes make them more resistant to flooding. It is better than nothing though, so we must keep in mind transition plans for farmland when trying to manage phragmites. We practice science to help every day people, not in spite of every day people. They should be included in all management decision making. We work for them not the other way around.

Competition is the name of the game for Phragmites. It beats is competition not only with its cloning abilities (there's a lot more to this but i had to read like 7 different papers to figures out wtf anybody was talking about so I'm not going into it) and sheer density, but it can also just poison the other plants around it. It can release a toxin that inhibits growth and seed sprouting in other species. It is also resistant to flooding and drought and it has been found that ground disturbance can make it spread faster. This makes it highly resistant to most disturbances that occur in marsh and wetland habitats.

Because it is resistant to like everything it is so hard to kill. To the point where some of the people who management have told me that eradicating it for an area is near impossible and an unreasonable expectation. Reduction has become the best case scenario. This makes early identification important. You can try to kill it by herbicides, mowing, fire, smothering with a plastic tarp, throwing a bunch of salt on top of it, and flooding with fresh or salt water.

The common reed is an interesting mix of being both a native and invasive plant. Phragmites australis has a subspecies native to North America, but this subspecies has been largely replaced by a more aggressive non-native European subspecies. Phragmites can grow from three to thirteen feet with broad sheath like leaves. Its considered one of the most invasive plants in the worlds having a broad geographic range. It exists on every continent except Antarctica.

As someone who has been in a field of them you can not pull these out of the ground. The tops break off but you have to dig them out of the ground if you wan them out. Also just a pain to walk through.

Here's a pic: (Yes that a person, yes they can be that tall)

Spraying phragmites today and while they are atrocious for wetland ecosystems here in North America, I can’t help but admire them. I think they’re actually very beautiful and I love how when they decide they want to branch out, one of the stalks just falls over and becomes the rhizome. Very impressive. I want to reinvent myself like that. I would love to visit their native range one day so I can appreciate them without also having the urge to set them on fire.

I will lay this [frag-mit-eez] dead, gods willing. Point me to him that I may stab him with my fucking spear.

I don't know. I just don't know
