Wildlife biologist here, Absolutely.

Oddly enough I usually see/write it fen/bog marsh. There are tons of other qualifiers too, like salt marsh, tidal marsh and such.

The same applies for all 4 examples if it's needed. Salt swamps and fresh water swamps and such.

I'm also curious. Can't find a way to subscribe to a thread, so I'm leaving a comment to check back later

That's mind bog-gling

I think this is more to do with scientists' definitions than English in general. See also: what is and isn't a nut, what is and isn't a vegetable, is there such thing as a fish.

1. Take a sip. Did you trip balls? Acid.
2. Take a red wire, black wire, and a clock. Can you power the clock? Alkaline.

Duh.

Just call it something online, if people don't immediately pop out of nowhere to correct you, then you're probably right.

1. Determine whether it's a swamp or a marsh.

2. Tell someone else you did your part, now it's their turn.

What, you don't carry pH test strips around as a matter of routine? /s

Lick it. Just a little bit. Just a little snaky lick...

Learn botany. You can tell the approximate pH from the species of plants growing there.

Just from what I found, swamps are wetlands with woody vegetation being what DOMINATLY inhibits it. So if it's mixed, find out what there is more of. If it's 50/50, I guess the universe collapses.

And a wetland with a neutral ph is just called a neutral wetland.

Everything is a wetland.

Sorry, I'm looking for you in the bog but you're not there

Fen the wetland type or fen the plural of (sci fi/fantasy) fan? Or had you heard of neither?

That's cuz ya basic like one :)

You are not reading enough fantasy books, then.

It's basically a bog with freshwater coming in through the bottom.

There are some in Massachusets, Colorado, Estonia, and this region of the UK called the Fens.

Pretty hecking neutral

LOUDER, FOR THE PEOPLE IN THE BOG!

Especially Fen!
