Hogs? I assume you mean pigs. Pigs pretty quickly learn how to avoid being croc lunch. The thing is, unless entire litters are taken along with breeding adults, the population will not decrease. In most places they already breed more than can be supported so a large proportion of each litter dies before maturity. Unless control measures exceed that over-breeding any decrease in numbers is almost immediately replaced and achieves nothing.
@@itsamindgame9198 no he actually meant hogs (invasive wild boars, feral pigs are still a thing tho), those buggers destroy native plants by either uprooting them or sharpening their tusk onto the trunks of the plants, slowly killing them. sure they can learn how to avoid crocs. but at the end of the day they still need need to drink and they can only do so much when they need to go find a water source to drink from. where most crocs usually stay in because they know prey needs to drink and can ambush them pretty easily
@@DRskeleton654 You guys SHOULD CHECK OUT the Boar Buster traps that can trap up 35--45 Hogs/Pigs in One drop. A lot of places in the Southern states;ESPECIALLY Texas use them.
Dingoes are the biggest hunters of rabbits as well as feral goats and will kill any fox or cat that invades their territory. Problem is that we've killed most of our native dingoes so sheep farmers can make greater profits.
As a Moroccan, we have many problems in our native ecosystems that is day after day in suffering (Morcco is a biodiversity hotspot, espetially in the Mediterranean Basin ). I wish if you could cover topics about Morocco and other countries that aren't covered that much . (Excuse me for my English)
No, the rabbits in Australia did not all come from 13 individuals. There was "society" (club) that actively worked to introduce as many European species of fauna and flora as they could. Thomas Austin released 24 rabbits (not 13) in 1859, but by then rabbits were already common, and on Tasmania had long reached plague numbers.
The Australian Acclimatisation Society was releasing European animals into our forests from the late 1850s onwards... First in Victoria but soon all states had them, later not restricting it to European animals only.
I may be late, but you should’ve added the red fox and the wedge-tailed eagle. These Australian eagles are basically the only Australian super predators that will be more than happy to prey on the invasive red fox. The eagles also compete with the red fox for the same prey, which may affect the fox population negatively. So they’re *REALLY* important to preserve in the Australian ecosystem. They’re basically the golden eagles of Australia (golden eagles eat red foxes in the fox’s native range). Edit: I’m you’re new sub. That’s why I’m late to this amazing video. I love studying animals and wildlife as well :)
Where i live in regional NSW, Small little town called kandos, there is a place called dunns swamp aboriginal name (ganguddy) you see quolls, possums and goannas all the time, I remember about 10-12 years ago i was out there camping with a few friends when one of the curious little fellas came up to our campfire in the middle of the night to see what was going on he/she just milled around the camp completely unaffected by our presence it was such a surreal sight to see one of these guys up close they truly are amazing animals and look even cooler in person up close, random story just thought i'd share
In Tasmania there are very few evasive Foxes. The reason is that the native Tasmanian Devil finds baby Foxes delicious so what few Foxes can get from the mainland can't breed.
You do not get it. The evolution of life on earth is about invasive species. Only in the late Pleistocene/Holocene, there was an invasion of species (humans included) from Asia to North America, from Asia to Australia (the same) and not so long before that from North America to South America. And mind, those were hard times for local animal populations of all kinds. Not to speak about the coming of Polynesians to the isles and Maoris to New Zealand.
Of those species the water buffalo seems like one that could easily be dealt with. After all a buffalo can't exactly hide and you can feed allot of people at the same time.
@@awf6554 In the US, there used to be millions of buffalo. The US wiped them out if a few decades. You could shoot them from horse or train and keep going. There was often not attempt to even collect the kill. Put enough incentives out there, and they can be culled. I wonder if these buffalo are tasty.
Yeah. by numbers it seems like an easy amount to handle, but they do inhabit one of the most remote places in the world, even by Australian standards, and it is a hell of a lot of area to cover too. You are talking about hunting 150,000 animals, regardless of size, in an area probably a little smaller than the State of California.
Australia needs to make illegal to keep Murray Cod over 20 pounds and require them 3be released b back into the water. When that big they start eating carp over 5 ppounds!
I still don't understand your continued message of not 'villainizing' invasive species. If they are causing only a negative impact to the ecosystems where they are inserted, then there is no reason to be positive about them. We can easily separate them in their native habitat vs them in their introduced habitat.
This channel is in my opinion, 1 of the most considered, thoroughly educational wildlife channels on RU-vid. Whoever operated it, you're doing a phenomenal job and I commend you for it. I also wish you luck and hope you continue these videos for years to come. 👏👏👏👏👏👏👏
Saltwater crocodiles can grow up to 9 metres in length, not 6.3 metres. The only reasons why we don't see any grow past the latter length is because A: none of the current crocs are old enough to reach that size and B: They are either relocated to a crocodile farm or killed by rangers if they get too big. Salties can live up to a 200 years, and until they became a protected species in the 1970s they and freshwater crocodiles were almost wiped out by excessive hunting. As far as the Auzzie authorities are aware all the 9-metre long crocs were killed off over 50 years ago, but there is speculation that there might be a survivors that have avoided contact with humans by hiding in some of the most remote and isolated river systems in Western Australia, Northern Territory and Queensland. However, it is estimated that the wild population of salties is over 50,000 and there have been reports of salties being sighted as far south as Sydney, which makes sense considering they used to inhabit the area before Europeans arrived.
@@Is_This_Really_Necessary hate to be that guy but do you have a source for that. I just find it hard to believe that the climate in Sydney was so drastically different in the early days of colonisation. Its possible that 1000's of years ago they might have, but when nights in winter are regularly below 5 degrees it would be impossible for reptiles the size of crocodiles to survive
Feral rabbits in Australia ate every blade of grass and other vegetation in the landscape and turned it into a dustbowl desert. Australia naturally has deserts but these deserts were clearly expanded by the environmental destruction wrought by the rabbit. Prime farming land in Australia was ruined by the rabbit, to the extent that some farmers were forced out of business. The farmers tried everything, shooting, trapping, poison baits, and even blowing up rabbit burrows with high explosives, all to no avail. Myxomatosis was the first biological control agent that worked. When myxomatosis was released sometime in the 1950s it wiped out the rabbit almost overnight, and the Australian ecosystem dramatically visibly improved. By the 1990s the rabbit had started developing immunity to myxomatosis, so the calicivirus was released to keep the rabbit down. There is now evidence that the rabbit is developing immunity to calicivirus too, so we Australians better get our act together and develop another rabbit control agent pretty soon.
prob but great whites almsot never attack salt water crocs great whites are specialised to attack mammals not reptiles so def when a Grerat white can choose between a Seal/sealion and a Croc they got for the seal/sealion
well, in most cases it would be the other way around. The croc would eat the Great White. But yes if you are talking about a record Great White of over 2000kg, then they could take on most Salties. But there is not many of those, if there is at all after the way Great Whites were hunted into rarity in the past. It takes time to get to those sizes. Same goes for Crocs to, they used to get a good deal bigger than they are nowadays.
@@palmarolavlklingholm9684 the croc wouldn't even know what's coming the shark would strike from under as usual and severely damage if not kill the croc because it would hit the croc in it's bell that's soft but if the croc knew what was coming than the fight could go ether way
One species which is probably the most over looked is the larger monitor lizards in Australia which grow to be some of the largest in the world and have control of rabbit, feral cat and fox populations.
I want to hear about "ancient" invasive species. like, species that were introduced by humans when they began spreading out. like the dingos or singing dogs
And what about a dingo? From what I have read it came to Australia with Aborigines only about 30 000 years ago and was possibly one of the factors that devastated the megafauna there.
The 1800's: My Brain 🧠 Perceives this era as this time of "MASS over hunting." Look at the pictures of those Murray cod, the American bison 🦬, the Beaver 🦫, mink farms, the tasmanian tiger, wolf/bear/cougar, mass rabbit hunting) *I'm not against hunting. I just wish we could have found a sort of balance point instead of these cases where we hunted animals in the past to near extinction or actually to extinction. Like the Dodo 🦤 bird and Seal's... Whale's... This was tough times where survival was difficult but I wish we could have seen just how much we need animals. We can't get rid of all of them and not let their populations rebound.
Dingoes deserve a shout out, as not only can they control rabbits, cats and foxes but have been seen hunting large mammalian invaders as well such a hogs, camels and even water buffalo. However their success is hampered by the famous dingo fence as well as a lack of tolerance by Australians.
The poor animal has two names now depending on the circumstances. They're Dingoes when they want to promote them or Australia and call them wild dogs when they're being anything else. The fences official name now is the Wild Dog Fence, at least in NSW anyway.
Dingos do not control fox and cat populations... that's a huge lie spread by the pro dingo lobby... I have been trapping and killing dingos for years... I regularly get foxes and cats moving through camera traps within 5 minutes of a dog passing... The dingo is a feral pest.
So, then why don't humans eat the buffalo and carp (along with the feral dromedaries, horses and donkeys). Instead of ridiculously trying to raise cattle and sheep in the hot, dry outback, a place where they ecologically don't belong.
Australians do eat buffalo (especially in the North), though the infrastructure where they live, just as with camels and donkeys, is inadequate for processing and distribution on a large scale, given the inaccessibility and/or enormous range of the places they inhabit. It's just not cost-effective or profitable enough to warrant the necessary investment without a much larger, sustainable market. Carp are are used on a large scale for fertiliser production but again, limited infrastructure for transport, processing and distribution means low profit-margins for this industry. There is no sustainable market for carp as food in Australia and international prices for their meat are too low to warrant catching them for export.
Another predator that preys on rabbits are the Monitor lizards or Goannas. And speaking of Goanna, maybe they should introduce a certain large species of Goanna named after a certain Indonesian island to Australia to deal with a certain humped mammal from the Middle East. It may sound like putting gasoline on a fire by introducing Komodo Dragons to a continent that's already having trouble with invasive species, but I read somewhere that Komodo Dragons used to inhabit Australia along with their larger prehistoric cousin Megalania. And camels have no experinece with Komodo Dragons which have experience hunting large mammals.
Humans : live where crocodiles live Humans : know in these rivers live Crocodiles Humans : still let theyr livestock roam free around these rivers Humans when theyr livestock gets killed by the Crocodiles : :O the more you think of it they more oyu question if humans really as smart as they belive to be XD
How far back do you go to determine 'native species'? Australia was once connected to other lands, do you go back that far? Do you include humans in that invasive species list? As for the rabbit, their numbers were already in decline before myxamotosis was introduced, if you look into the scientist that introduced it you will find he later ignored the data and kept pushing his program, I think because he had already built a career out of trying to eradicate them There has only been one study into the positive effects of rabbits and that was done in the US and they found that rabbits are of benefit in hilltops because they keep small plants at bay whilst allowing the larger shrubs to grow and not be outcompeted which increases the stability of the hills The whole notion that we need to somehow wind the clock back to a point in time and say at point XYZ in history is what makes up a native species to me is flawed, as I said before, how far back do you go? Why not back to when the land masses were joined? Until studies are also done on the positives of an introduced species then we are really only looking at one aspect and what about humans, why should humans get a free pass?
hi, can u explain to me why Australians consider the dingo to be invasive even thou every website i look up classifies them ether as endemic or native to Australia? cuss seems to me like most of australia's invasive species problems could be resolve by just letting dingoes do their thing.
because of feral dogs are the main issue and cross breed with the pure dingos. doesn't help they damage our livestock industry which cause 100 of millions worth of damages not many pure breeds dingos left the the government has declared that they are pest as it's easier than to check every feral dog on the land
The dingo isn't classed as an 'invasive species', though it is thought to have been on the continent les than 5,000 years. Dingo hybrids with domestic dogs are though and it's these hybrids and feral dogs which cause most problems for farmers around national parks and reserves in rural communities. Many of the areas the dingo used to inhabit are no longer suitable habitat for them, particularly the regions where farming and cultivation is prevalent along the East and South coasts and where feral dogs are subject to control measures. Feral dogs and hybrids can breed twice a year, while dingoes only breed once a year so in areas where food is abundant, feral dogs can out-compete the pure dingoes over time.
Dingoes were brought to Australia by the Aboriginals , not Europeans so depends how far back you want to go to be considered ‘native’. First humans were thought to arrive around 40,000 years ago are they native ? Kookaburras , native to Eastern Australian have been introduced to South West Australia were they are considered invasive.
Dingoes are considered a pest because they kill livestock and were doing so long before they started crossbreeding with domestic dogs. That's why they have been persecuted by the European invaders for two centuries.
The video fails to mention cats. Cats are the major predator for native species including birds. Since their introduction by Europeans and Asians they have completely decimated native species and ecosystems.
Other than irresponsible aboriginal burn off's, the biggest problem is feral cats regarding extinctions. Sorry to upset all the virtue signallers out there but facts are facts !
Nice video. Even though the native species van feed on them, a fast growing invasive species can result in a fast growing number of predator species as well. But, they not only feed on the invasive species, so they might pose an even bigger pressure on the native prey population as well.
@@aurochsxx5932 Well, there are proof of Nile crocodiles killing and eating a grown hippo. Nile Crocks are much smaller than Salties, and Hippos are much bigger than Water Buffalo. Add to that, Salties are more aggressive than Nile Crocs, and you can bet your ass that Salties can take on a measly Buffalo.
@@palmarolavlklingholm9684 this and one other time ive seen it Salties have doubts over attacking water buffaloes.. ..nile crocs though small are habituated to killing larger mammals and they are accustoned to work as a group unit so its likely salties rather kill fishes, other small croc species, kangaroos and water birds ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-m__ECOcaCTw.html
Would like to see a video on Australian native species that have been become pests elsewhere. From possums and wallabies in New Zealand, redback spiders in Japan, black swans in Europe, and so on.
I'm in my mid 50's now, and I've seen a photo of my class mate grand parents' wedding feast, which had a baked whole Murray cod. The length was over 6 feet.
Wow this channel is great! I love that you added that it's not the individual animals "fault". Some people might use them being invasive as an excuse for thier morbid desires. How about adding diffrent methods that might help out? Like judas goats and what not. Maybe also what viewers can do to make a difference. Like contacting politicians and where to join conservation efforts (or eradication efforts).
I love how "invasive species" are dirty words. Newcomers are evil but long-term residents are virtuous. Species are constantly on the move and every species was "invasive" at some point in the past.
"A cane toad's toxic can prove fatal" A cane toad's toxic WHAT can prove fatal? Buffaloes in ALL habitats in the Northern Territory. I would check up on that if I were you. There are not very many water buffalo in the deserts.
Thanks from a wildlife lover in Australia, I actually care for 2 pure desert dingoes, sadly we lost our 3rd princess Sandy Maliki to a black snake bite. We have a battle here where our apex predator the dingo is universally treated by government as a pest. The reality is it could easily help bring back a balance in the bush by eradicating rabbits, cats, pig and fox. The problem is dingoes can interbreed with domestic dogs. It is this interbreeding that leads to 'wild dogs and packs'. Dingoes need protection and reintroduction. I know it can be done but we need support from the government. The dingo is UNIQUE, I know I have raised and cared for 3. Sandy's genome is being studied and its now accepted that dingoes are a unique species internationally. Anyway good balanced commentary.
Well as it turns out none of the native animals in this vid make any dent at all in the ferals since they're numbers are absolutely enormous. I'd argue (correctly or incorrectly) ferals only increase from predation by natives since it creates just the right amount of pressure for feral numbers to increase which is partly why ferals are so successful. The amount of feral camels, rabbits, goats, pigs, dogs, cats, water buffalo, carp, cane toads, deer, foxes, rats, mice, munas, sparrows and of course idiot horses so on and so forth into infinity is utterly demoralizing and I've only mentioned the animals. So I'm thinking best case scenario if Quolls, Salties and Murray Cods take a half dozen ferals a day, I don't thing ferals have too much to worry about, do you? Sorry maybe Cod take a thousand carp a day in the Murray-Darling catchment but no one is seeing much of a decline in Carp. Also Dingoes eat rabbits, so do cats and wild dogs.
Foxes became a huge problem also in my country - Poland. Because they are intelligent, omnivorous, and cunning. Foxes can survive on only what people throw away or leave behind, so there are no natural limiters to the excessive growth of their population in the form of a lack of prey to hunt. And as a result of human activity (the elimination of wolves and the lack of hunting), they had no enemies. They multiplied beyond measure and began to threaten the populations of other species of small birds and mammals. Paradoxically, predatory wolves, foxes' natural enemies, contributed to the revival of the population of hares and partridges, because they returned to their former hunting grounds and quickly eliminated the competition. That is foxes. I mean, they've reduced their population to a manageable size.
The Australian government does not do much at All! Eg: Indian Minors are Just ignored! Yet India are Missing them!! Why not Export them there! Rather be invaded while sitting at an Outside Meal running on Tables!! Cronulla in Sydney is bad with them!
The introduced species that poses the greatest threat to Australian biodiversity is Lantana. Wildfire is only a problem in Australia because "environmentalists" insisted on stopping traditional indigenous burns, which were done over small areas during cold weather. The same happened in North America, and in both cases, traditional burning practices are being "rediscovered" as a way of preventing uncontrolled fires. Australian native plants are adapted to the traditional burning patterns and grow back very well after fires, but are damaged by more intense wildfires. Imported plants tend to handle infrequent wildfires well but don't cope with more frequent traditional fires.
Don't call it a comeback, I been here for years I'm rocking my peers, putting suckas in fear Making the tears rain down like a monsoon Listen to the bass go boom Explosions, overpowering Over the competition, I'm towering
What they should do in Aus is find out what hunts the invasive species then breed thousands of them, neuter them and let them go, they can be trained to only attack the target species, apparently there are already some animals that are being trained to do this, I realise it won't work with all of them but it can work for others. They should also give open licences to hunters to hunt and kill the bigger species and give the meat to countries where people are starving.
pigs, foxes and moggies, aside from the cane toad are our biggest invasive species problem and the local carnivores cant compete with them and in fact are often eaten by cats. rabbits are under control at the moment due to mixy and calicy. salties are on the way back because we don't shoot them any more. the cane toad being poisonous has done enormous damage and some people are trying to train quolls to avoid them. I understand they have had some success as the adults seem to to pass on the knowledge to the next generation. but they also kill snakes which feed on the next biggest problem , mice. They often go unremarked as a problem except to the farmers. But a mice plague has to be seen to be believed. Literally millions of them. Some years ago in Dubbo I saw a 20M pool totally blanketed in drowned mice. P.S. Loss of habitation is also killing off the local predators
you know if the farmers would just harvest the buffalo you could probably solve both the buffalo and salty problems. This isn't really a good example of an invasive species problem as it is of 2 miss-managed natural resources.
Marsupials from the opossum family are pretty good at coexisting with invasive species. Tough too. They are rather similar to the mammals that coexisted with the tyrannosaurs but then survived the asteroid.
What nonsense, Australia has always had bushfires, not just recently, and there are also more kangaroos than people, so don’t show footage of kangaroos while talking about threatened species.
Ranchers got upset about the last big water buffalo and camel culls because they have developed markets and can sell all the water buffalo and camels they can round up. Markets are being developed for venison too.
99% of species to ever exist are currently extinct. Change is the only constant & the world will keep turning despite our screw-ups, and our efforts to correct them.
If your native species cannot control the invasive species allow controlled culling through hunting. And allow hunters to give the cleaned kills to food shelters for free. Feed the poor and save your ecosystems.
I don't like the stock footage at 6:14. He's loading the magazine with the rounds facing himself. I know it's not dangerous but still... it's like watching someone sit on the edge of a cliff.
Shame we can’t get rid of cane toads ironically, since their poison is strong enough to kill even our poisonous/ venomous creatures Now I don’t know if poisonous or venomous creatures have resistances to their own abilities
Human beings are the biggest threat to any environment............seems a bit hypocritical to blame rabbits and other animals that were introduced by said humans..❤❤❤
To control the buffalo, why not just time travel to when European settlers got to North America, and bring those soldiers who eradicated herds of bison.
