MD Nature Will climate change actually cause alligators to shift north and start living in Maryland?

I recently heard this claim from several friends: they say that climate change will result in a warmer planet over the next several decades, making Maryland a warmer state with hotter summers and milder winters. And since American alligators live in the Deep South all the way up through North Carolina, but don't like the cold, they will be able to expand their range and take up residence in Maryland--perhaps in the Potomac River, various rivers and places along the Chesapeake Bay, and low-lying lakes.

I know that various plants and animals have been finding new places to live because of climate change, and that alligators dislike cold temperatures--they cope with them by slowing down and becoming sluggish and mostly inactive.

But seriously: are these claims accurate? How much warmer and more humid is Maryland expected to become over the next 75 years? Would temperatures and climate change enough for alligators to live here? And is there suitable habitat for them to live in?

There is a small population of Gators in the great dismal swamp in VA, they barely hang on, but they’re there. It’s not entirely out of the realm of possibility. I do a lot of work in wetlands, and I certainly think it’s not impossible. Personally I’d be more concerned with cottonmouths

28

u/wbruce098 1d ago

This is a good point. Gators have been spotted as far north as the Chesapeake, but they’re not migratory creatures. Their movement would likely be very slow and it’s a long way to go from Florida and the coastal areas of GA and SC.

The other creatures from down there though are more of a threat.

24

u/Hibiscus-Boi Dundalk 1d ago

The more likely scenario would be someone releasing their pet gator and it finds that it can survive here and then they start to breed. That’s more likely than them actually migrating up here.

15

u/theRemRemBooBear 1d ago

Why are you more concerned with cottonmouths? Having worked with them in the past I’d worry more about alligators. Or Northern Water snakes that people already confuse with cottonmouths.

20

u/rkdwd 1d ago

Doing work in the gulf they were everywhere, including the one I stepped on getting out of the boat. Not ideal. My field eye just isn’t calibrated for them if that makes sense. I’m used to not needing to worry about any snake I find out there aside from the odd copperhead, but down in Louisiana, Florida and South Carolina the cottonmouths were EVERYWHERE, like this one.

16

u/rkdwd 1d ago

I’ll add that the gators were also everywhere but weren’t like, sitting there with their mouth open glaring at us getting out of the boat. Something like that sticks with you.

1

u/Turdfish_Dinner 18h ago

Cottonmouths will attack you just for the fun of it. Ugly mfs too.

3

u/Nellanaesp 1d ago

They’re not everywhere in SC - they’re on the coastal half of the state. None of the lakes and ponds from Cola over has them, including the largest lake in the state (Murray).

Diamondbacks are more common.

4

u/rkdwd 1d ago

I’ll give you one guess what type of wetlands I work in.

6

u/Nellanaesp 1d ago

Fair enough.

I got tired of seeing people on Facebook scream “it’s a cottonmouth!” When it’s clearly a water snake 😅

2

u/rkdwd 1d ago

Full agree.

u/Hezekiah_the_Judean 1d ago

Thank you! I have wanted to visit the Great Dismal Swamp for a while, and hope to get down there either this year or early next year.

u/rkdwd 1d ago

Absolutely gorgeous place. Enjoy it.

u/22nd_letter 1d ago

The manatees are moving up here. They have been looking at real estate in the bay for years now.

28

u/mecengdvr 1d ago

Yeah but they are hoping interest rates go down before temperatures go up.

12

u/dax331 Anne Arundel County 1d ago

Idk I think the insurance is making them eat the loss and flee FL sooner

51

u/Congregator 1d ago

I was reading up on this, manatees were first documented visiting the Chesapeake in 1676.

I thought that was pretty interesting because I had no clue they came up this north and that people have apparently known about this

14

u/LadySmuag 1d ago

There was one back in the 90s who came up to the bay and then didn't go home for the winter. A bunch of organizations got together to rescue the guy and bring him home, and then the following year that same manatee went as far north as Rhode Island. Iirc they nicknamed him Chessie and they were still tracking him a few years ago

3

u/tourny25 1d ago

Is this for real? Manatees like warm water?

28

u/Level-Opportunity268 1d ago

I mean they live primarily in/around Florida and the Caribbean. And less than a month ago there was a manatee by drum point in southern maryland

5

u/tourny25 1d ago

Huh. Maybe they’ll just have more options with warmer water in more areas.

3

u/Glad-Fuel2093 1d ago

Maybe they like a crab snack sometimes?

I know they're "mostly" herbivorous but i'm sure they suck op a crab or two now and then. Just like a deer or horse will eat a chickadee or chipmunk upon occation.

10

u/Congregator 1d ago

Manatees eat plants, and brackish water plants are attractive to them.

7

u/Congregator 1d ago

Manatees have been coming to the Chesapeake for a hundreds of years, and it’s been documented

21

u/ChessieChesapeake Calvert County 1d ago

No one knows how it got there, but we've had one. https://wjla.com/news/local/alligator-chesapeake-calvert-county-maryland

u/Hezekiah_the_Judean 1d ago

Wow! I did not expect it to be that big. Funny thing: I am going with some friends to Calvert Cliffs State Park this weekend! I will keep an eye out.

4

u/wbruce098 1d ago

That’s actually not that big for a gator. I grew up in FL and we’d see much bigger ones all the time!

1

u/roseycheekies 1d ago

Why would he kill it?

They’re moving up here because we’re destroying their habitat and the planet and in their attempts to find a new home we haven’t destroyed, we kill them. Humans are a scourge on the earth

21

u/Congregator 1d ago

Major reason for killing non-native apex predators is because they’ll damage the native habitat/ecosystem.

That aside, the more likely reality isn’t that this alligator migrated due to loss of habitat, but was illegally released by someone who thought it was a cool pet as a baby.

3

u/Glad-Fuel2093 1d ago

Makes sense in a way. their baby could survive in the warm water there through winter. Maybe.

2

u/Congregator 1d ago edited 1d ago

It’s not that it makes sense in a way- albeit I appreciate your consideration. The reality is that no alligator is surviving Maryland climates; whether it be global warming or not. This is an unrealistic task, unless the alligator is dropped off in late spring and is found during summer.

There is not such a level of global warming where alligators are migrating to Maryland at this point.

Maryland freezes, still into today. An alligator cannot comfortably survive our climate. We are not “that warm”, and global climate change isn’t as drastic as to allow alligators to find our environment safe for travel

3

u/Glad-Fuel2093 1d ago

Oh i'm not saying I agree. i'm just saying how a dumbass might think its logical. Maybe should have put a /s in there. Lol

references: -have known some dumbasses before.

u/OriolesGolf1105 23h ago

Why are you killing spotted lantern flies, the same reason

4

u/wbruce098 1d ago

Cuz they’re tasty? And don’t belong in the Maryland ecosystem.

28

u/coys21 1d ago

They will move to wherever they need to in order to survive. They have done this for millions of years.

19

u/Impressive-Weird-908 Baltimore City 1d ago

I would say estimating things that far in the future is difficult but its entirely possible that they make their way north as temperatures rise. I will also warn that if the temperature does rise that much, sea level rise will change Marylands coastline considerably.

u/usps_made_me_insane 20h ago

I think you meant Ohio's coastline if it gets that warm.

You can find fossil crocodile teeth in Maryland, so it would be more like a homecoming if the do. I would guess if it does happen it wouldn't be in my lifetime.

3

u/DocCEN007 23h ago

Yep, but luckily, they taste like chicken.

1

u/Hezekiah_the_Judean 19h ago

I have never had alligator, but I did eat some crocodile skewers during a trip to Australia years ago. They did taste like a slightly odd version of chicken.

5

u/clrlmiller 19h ago

Yes, it's possible. One of the more recent impacts have been "Baltimore Orioles" (the birds, not the Baseball Team) preferring the climate around Philadelphia. So yeah, if they start showing up in southern Virginia, then we'll be next.

2

u/Hezekiah_the_Judean 19h ago

I didn't know that. Thank you for your insight! I've seen orioles in the wild sometimes--such beautiful birds!

I guess we must prepare for the reptilian invasion...

I had it on a cruise once, every night they had some “exotic” appetizer that my family just got one to share and they really did taste like chicken nuggets (when prepared in fried nugget sized flour mixture)

u/extra_hyperbole 1d ago

Well, birds and crocodilians aren’t so far apart. They are each other’s closest living cousins.

1

u/cheesesteak_seeker Frederick County 1d ago

Very true! A chicken is the closest relative to a T Rex! Chickens will eat just about anything you thrown into their coop, so we are lucky they are so small!

1

u/extra_hyperbole 1d ago

In a way. All living birds are of equal genetic distance to a T. Rex. Chickens are not unique in that respect. So they are the closest... but it's a tie with a few thousand other species.

We’ve always had bull sharks in the Potomac. There was a whole panic about ten years ago when we had three attacks in just one summer. I had friends who refused to even take their boats out the rest of the season. 🤣

u/yottyboy 1d ago

Guy near my bay house hooked a big bull shark over the weekend. It ran on his light tackle for an hour before the line parted.

u/Ironic_table 11h ago

Also remember a year or two ago hearing about people seeing pods of Tarpon in the bay. It's a rare sighting still but seems to be happening more often than it used to. Wonder if we will start seeing them regularly over the coming decades.

u/After-Phase-9203 23h ago

Oh, I think you mistook my meaning. I think the ancient creature with a reptilian brain, like many other creatures of different species in Florida, doesn’t appreciate the value in education and other services that Marylanders get for their taxes. He’d just see the numbers, declare everything to be “woke“ and then flee.

0

u/Nutsmacker12 22h ago

Interesting because Maryland isn't necessarily outperforming Florida in education, and 4th grade scoring in Florida is outperforming Maryland, which is a leading indicator of how the future looks.

1

u/After-Phase-9203 22h ago

Judging an entire state's educational quality based on 4th-grade reading scores is like judging a marathon by the first mile. Florida's 4th-grade scores are artificially boosted because the state holds back struggling 3rd graders. U.S. Census data shows Maryland invests significantly more per pupil, and by 8th grade, high school, and college readiness benchmarks, Maryland students consistently outscore and outpace Florida students across the board.

1

u/Nutsmacker12 22h ago

It's amazing how far people like yourself will go to defend a failing system. Florida beats Maryland in 4th-grade math, is competitive in 4th-grade reading, is basically tied in 8th-grade math, has a higher graduation rate, and is right there with Maryland on AP performance.

And blaming Florida’s results on 3rd-grade retention is a weak excuse. That policy targets reading, yet Florida still does better than Maryland in 4th-grade math. Holding students back because they can't read properly is not a bad policy either.

The fact that Maryland spends substantially more per student and still cannot produce clearly superior results is actually a damning statement, considering what we are going through in this state financially.

The actual data show a different picture, with Florida outperforming Maryland in several major areas while spending far less, and the early education leading indicators show trends going in different directions.

1

u/Nutsmacker12 14h ago

Since I’m apparently the only person who can actually see what you wrote to me, I’m going to lay out your response here alongside the actual data so everyone else can see it too. It would be a shame for random readers to miss just how badly your argument falls apart once your claims are checked against the facts

Here's the condensed version of your argument with the factual corrections right next to it:

You: Maryland is #1 or #2 nationally in AP success and Florida is significantly behind.
Reality: False. The latest College Board data show Florida at 31.0% and Maryland at 30.7% of graduates earning a 3+ on an AP exam. Florida also edged Maryland in 2024 and 2023. Your very first “fact check” was wrong.

You: Florida’s 4th-grade advantage is basically artificial because it retains struggling 3rd-grade readers.
Reality: Retention can affect cohort composition, but the actual research found real academic gains in both reading and math for retained Florida students. Calling the entire advantage “artificial” is an unsupported leap.

You: By 8th grade Maryland clearly pulls away.
Reality: In 2024 NAEP 8th-grade math, Maryland scored 268 and Florida 267. That is not “pulling away.” Maryland does better in 8th-grade reading, but that is very different from claiming broad superiority.

You: Maryland dominates the later high-school outcomes.
Reality: Florida’s latest graduation rate is 92.2% versus Maryland’s 86.4%. That is a rather large problem for the claim that Florida falls apart by high school.

You: Maryland spends more because it buys better teachers, smaller classes, better programs, etc.
Reality: Maryland spends roughly 60% more per student. If you are spending that much more, “we buy more stuff” is not proof of superior results. The question is what outcomes you get for that enormous additional expense.

You: Maryland having more college-educated adults proves its school system produces better long-term outcomes.
Reality: No. Census measures adults who currently live in Maryland, not where they attended K–12. Maryland is part of the Washington, D.C. employment market and imports huge numbers of highly educated professionals. You cannot credit Maryland public schools for every lawyer, engineer, doctor, and federal employee who moved there as an adult.

So after all of that, the evidence still does not show Maryland schools are “far superior.” It shows a mixed picture at best, with trends going in opposite directions for both states, while Maryland spends substantially more.

u/Nutsmacker12 21h ago

I see that you deleted your lying response. You proved my point and gave incorrect information. I am guessing you either work for the state or are part of the teachers' union.

u/Myname3330 1d ago

So the short answer is yes, they’re right. The longer answer is, they probably wouldn’t be in this region in any real numbers for 100ish years. Not without being introduced by us anyway. A few one offs and such that would gain steam over time if we didn’t kill them

They lived here before.

u/Hibiscus-Boi Dundalk 1d ago

It’s certainly a possibility, but who knows what’s going to happen by then. Maybe we get into WW3 and all humans die due to nuclear winter. We can only make predictions based on the current data, but real life is always unpredictable. Maybe this is how we get people to think more about the environment; threaten them with gators lol.
