3 Non-Native Animals That Were Introduced By The Government - Invasive and Beneficial Species

[@scarylookinhobo]

Love the video! I'm glad you covered the fact that not all non-native species are invasive, as many instantly assume that because it doesn't belong in a place that it must be harming the environment in some way. And thanks for covering my favorite owl :)

I know of at least two successful introductions in Australia that happened specifically to reduce the impact of other invasive species. Cactoblastis cactorum is a species of moth from South America, was introduced to control the spread of multiple species of cactus in the genus Opuntia, while 23 species of dung beetle were introduced from 1965-1985 to control the polluting effects of cattle dung. A third controlled introduction that also went well is of Aldabra Giant Tortoises on Île aux Aigrettes just off the coast of Mauritius, where they've taken on the role once filled by now extinct native tortoises in dispersing plant seeds across the island's forests. I even know of a 4th successful introduction on Bermuda, where Yellow-Crowned Night Herons were introduced in the late 1970s to control the out of control population of land-crabs on the island, filling the role of an extinct relative. All of those introductions have been very successful thus far, and if you have the time and desire I would love to see a video on them that goes into more detail on each introduction.

Coming from SE Queensland in Australia, I witnessed the actual Cactoblasts larvae eating the prickly pear and even took some pear to school for a "show and tell" event. Interestingly the cactus was introduced to the Sydney area in Convict Colony times as a food for the introduced Cochineal bug to create a red dye production industry in the late 1700s.

You're not allowed to talk about positive examples, invasive are evil and must always be stopped.

[@IanPendleton-gh6ox]

Invasives aren't evil, they're plants and animals just doing their best to survive. And you can't say I'm not allowed to do anything since you're just another KZbinr.@@dino_rider7758

3:42 I actually once saw a California Condor flying overhead while on a highway. I was in the passenger seat able to get a good look at it. But I wasn't able to take a photo on time. Still a cool experience.

[@tarotafterdark1077]

One of the reasons I gravitated and subscribed to this channel is because of all of the refreshing and unique topics covered. Great job guys! 🎉

[@MotoHikes]

Great video! I was unaware of the Andean/Californian Condor situation. Would love to see a part 2 of this! My suggestion for one would be the Nile Perch being introduced into Lake Victoria. It's such a complex situation that I studied for my degree, with socio-economic factors and tourism that then lead to a plethora of problems, not just environmental.

[@colinhundt4088]

I was glad to hear that not all government introduced non-native species turn into disasters. I would love to hear about others.

I thought I knew everything about the history of the California Condor but I never heard about them bringing in Andean Condors. Places like The Living Desert, in Palm Desert, California never mention it. Thank you.

[@boredwarlock5216]

More invasive species content please! Thanks I remember learning in biology back in high school that 1/10 introduced species will actually be able to survive in an introduced environment. And of that only 1/10 of those species will grow to become an invasive problem. Looking back on it I'm not sure such statistics can really exist.

Bringing mongoose into Jamaica to clear snakes from cane fields. It resulted in the extinction of many indigenous birds and the snakes are still there. Since I was a kid they would light the cane fields on fire to clear them before harvest. So you got pollution, massive fires close to roads and collateral damage to homes and businesses as a result.

[@chipsdubbo4861]

Hey Tsuki. Have you considered making a video about invasive species that just kind of got absorbed into the native ecosystem? Ones that a lot of people don't realize are invasive. As a Floridian. It always surprises me when people don't know that Brown Anoles aren't native. They're a very common and normal sight everywhere in the Sunshine State(Heck, just today I had to kick one out of my bedroom), and technically are destructive in the sense that they've essentially stolen the ground level predator role from the native Green Anoles. But since they've sort of settled into that niche, and aren't really threatening any species with imminent extinction. They aren't really mentioned much when people talk about invasive Florida species. And I'm curious about other common animals that people might not realize weren't originally part of their ecosystems.

You could do a whole video on Idaho fish and game. From the multi-mess ups in Lake Pend Oreille and Priest Lake. To releasing North Canadian Timberwolves into a warmer climate with all that implies.

[@JohnnyAngel8]

The doggie at the end looks like it's asking, "am I invasive?"

[@Redneckkratos]

8:20 I remember this comic showing how wolves were supposedly airdropped into areas where the moose were running rampant and unchecked and the wolf was being parachuted down with a knife in hand. I can imagine governments hiring Arnie to do that but in squirrel infested areas

[@EverettBurger]

Pleasant Pond, Maine. Clear, cold, and deep. State biologists thought that introducing lake trout would boost the tourism industry. Instead, they ate all the native trout and then everything else. Then, they starved. Now, it's pretty lifeless

[@rafAfernz]

In the Philippines you can also find barn owls with darker plumage.

[@justonecornetto80]

Another species to consider is the signal crayfish which was introduced by the Ministry of Agriculture and Fisheries into the UK during the 1970s so they could be commercially farmed for the Scandinavian market. When it got into UK rivers the impact on the native white clawed crayfish was devastating because the signal carries a plague that is deadly to them and outcompetes them for food.

[@brucebrazaitis321]

About Hawaii, During the 1950's when there was a big "Let's improve Nature!" they introduced three species of non-native marine fish. Two of them are very "weedy" the Blue line Snapper and the Argus Grouper. Both of these fish aren't that large so they are about panfish size around a foot in length so they were not popular food fish. In fact one book I found about cooking Hawaiian reef fish mentioned that blue line snappers could be bought for next to nothing in the local fish markets if you didn't mind cleaning a lot of them for a meal. Of course they must consume more other reef fish than lion fish do. Peacock bass in Florida are interesting since the tilapia they were introduced to control were also introduced by the state for aquatic weed control.

[@anniehill9909]

Sadly, there are probably too many 'officially' introduced animals to count! Living in New Zealand, I am only too well aware of the damage that they do. It's nice to see a couple of introductions that haven't actually run amok. Apparently, barn owls have now self introduced here, from Australia. They are being very carefully monitored.

[@Account_Nxme-iq9eu]

Also another examples: 1. Cats - Introduced to get rid of rats and rabbits, becomes invasive 2. Cane Toad - Introduced to get rid of cane beetles, becomes invasive 3. Wild Boar - Introduced for hunting purposes 4. Foxes - Introduced for hunting purposes 5. Rabbits - Introduced for hunting purposes

[@supercatcreative4381]

Have you heard of Asian carp? It is an invasive species in the Kentucky part of the Ohio river

[@kendallkahl8725]

The only way the Mississippi, Missouri and Ohio River basins will regain any sense of normalcy since the Asian carp invasion is if Eurasian species that prey on them are introduced. Mainly the giant predatory catfish and carnivorous cyprinids such as the Asp, Predatory Carp, Yellow Cheek and several others. The giant catfish would be the most safe option. They found that where the Weels catfish have been introduced to European Rivers they have no effect on game fish numbers or weight caught and only dropping carp numbers.Perch, Zander, Pike and introduced Bass and Sunfish didn't change much at all. In fact numbers went up without carp eating their eggs. They may be just too agile and swift for the Weels. Thevp only sizeable predatory cyprinids we have are the Pike minnows . While Colorado pike minnows are the largest they are too picky regarding water conditions with flows needing to be just right, ph needing to be just right and temperature requirements being exacting. Colombia and Sacramento Pike Minnows are smaller but way more tolerant. West of the Continental divide American Rivers are like Asian rivers but east of it American Rivers are more like African, South American and European Rivers.

The barn owl is not 'absent' in large part of Asia. It's just that other barn owl species exist there. The Philippines for example have a native Australasian barn owl (Tyto longimembris).

[@davemyers7507]

Cool 😎 thanks for the update 🎉

[@1fishmob]

Have you considered making a video on the new methods that scientists are working on to control invasive species? Like daughter/sonless gene drives?

[@toonrex2806]

Imagine if the Saltwater Crocodile was introduced to Hawaii. Being an apex predator, I imagine it taking over the island’s ecosystem.

[@mtkoslowski]

Perhaps the authorities in Illinois should consider introducing the peacock bass into their waterways to try and get rid of another invasive species, the Asian carp.

[@Daave12953]

Good video ❤

[@Nigel_BC]

Could you do a video on how large mouth bass are invasive in many states on their native continent? It’s an issue that I don’t Enough people know about or talk about.

[@BlackZak727]

[@robertfletcher3421]

I would like to mention a UK invasive species. The Yellow Tailed Scorpian at Sheerness no problem as they stay in a small area but what happens when the climate warms.

[@AndyFromBeaverton]

Asian carp and starlings have to be the most devastating introductions to North America.

[@joseph-pf5fr]

At least the barn owl is active during the same time as the rats unlike the Indian mongoose that was also introduced there

The blue catfish in the Chesapeake bay is a DIRE ISSUE with out native ecosystem. Released by Virginias State wildlife officials for sport fishing in the 70s and 80s in the James and Rappahannock Rivers and now are the #1 predator of all of our rivers and the bay its self.

In the UK do y'all have the song "The Old Lady Who Swallowed a Fly"? It seems like a metaphor for invasive species sometimes. It's about a woman who swallowed a fly. She then swallowed a spider to catch the fly, and swallowed more animals to solve the problems caused by swallowing the previous animal.

[@pirobot668beta]

How about the terrible 'de-introductions'? Wolves, coyotes were exterminated in the American southwest...now the very same regions are being over-run with Wild Boar. Take away the apex predators...what did you expect to happen? Now people have to go 'hunting' wild Boar so their farms won't be destroyed. Wolves and coyotes don't eat corn and grain crops...Wild Boar most certainly do.

[@Angel-od1bt]

Yeah, arguing with the people that want the apex predators removed is so infuriating. I live in Scotland, and the red deer, although native and one of the stunning species associated with the Scottish highlands, now have no natural predators, they’re far too big for a fox. They ring the trees, killing them, and the highlands are almost completely deforested. Part of reforesting involves culling them. We need to bring back the good old fashioned tradition of the livestock guardian dog. Perhaps not suitable in all systems and climates, but destroying what’s left of the world’s largest predators is not an option and they are quite effective. Especially since apex predators are also keystones in our entire ecosystems, removing them spells disaster for all of us.

[@slipstreamxr3763]

Though not an intentional invasion the success of the American Mustangs after being reintroduced to NA by the Spanish in the 1500s, is another example of an "alien species" being beneficial to the environment. After being reintroduced horses just went back to doing what they did in America for 50mya before going extinct here only 10,000 years ago. Sadly, camels were not as successful here in the US, even though they are native to North America as well.
