    Interesting about worms. I knew hardly any of that.
    The place I always bought bait from for fishing stopped selling the regular earthworms you get, and got a local supplier of native worms, which were fairly pricey.
    All the cashier could say was, "I guess they're bad for the environment." Couldn't elaborate more than that. I thought they were being totally ridiculous, like it was a real life example of green-washing.
    Evidently the owner was paying more attention than I was.

    Interestingly Cane toads have other indigenous predators that have adapted. Two come to mind that use intelligence. Both species i will mention seem to teach a learned behaviour to offspring, making it even more interesting. It is based upon the toxins on a cane toad being produced on the top of the toad, not the underside.
    Marsupial river rats in the Kimberley will disable the toad by flipping it over, then uses a large claw to create a surgical slit in the belly to extract the liver, which it likes to eat... the problem is that the marsupial water rat only likes large toads, because they have large livers. thus the toads are slowly being naturally selected to be smaller. Marsupials rats tend to teach their offspring as they raise their offspring with them as they hunt.
    The Australian Raven also uses intelligence to hunt toads. They once again flip them over and then eat them from the underside. As the Australian Raven lives in organised family groups, then this quickly spreads amongst family groups as a predatory style.

    Another really cool story of an invasive species are the Judas guitars goats of the Galapagos or 'Project Isabela'. Basically goats in the Galapagos were obliterating the habitat and endangering other native species. So Project Isabela had one goal: 100% eradication. But as the managers told it, the last 5%of the first population took as much effort as the first 95%. As remote a the islands were, it was difficult to get resources out there to hunt the goats and the most efficient way was hunting them in a helicopter. But as their population dwindled and the vegetation returned, the goats got smart and hid when they heard the helicopters. Enter the Judas goat. A female goat was captured, sterilized, tagged with a GPS and infected with hormones to permanently put them in heat and make them irresistibly attract other goats. The Judas goats lived up to their name, condemning many of their fellows and leading to total eradication on most islands. Those that remain are mostly protected for political reasons.

    As someone who's been in the aquarium hobby for quite a long time, and also an avid angler, I'm quite familiar with invasive species and the damage they can do. It's part of the hobbies if you get very far into them. I've also owned a couple self-cloning crayfish (what we call them in the hobby), and was already familiar with their origin. Sadly I never got them to the point of reproduction, they managed to escape and die outside of their tanks.
    In my experience, the term "invasive species" has always been used specifically regarding a non-native species that was detrimental to the environment it was introduced to. I've never heard invasive species used when talking about an organism that wasn't detrimental.
    It does get incorrectly used in other ways though. Angling is an area where this commonly happens. Many people consider fish they don't like, "trash fish" and such, invasive simply because they aren't the fish they like. Gar fall victim to this a lot. Many people consider them invasive in a lot of places, even though they're native and have been there longer than humans have.

    • @dddkll

      I was wondering about the use of the term invasive in that last section. I’ve always understood “invasive” to mean harmful to the local ecosystem and “introduced” or “established” to mean nonnative but not harmful. This is a distinction that’s frequently overlooked in the gardening hobby, where any rapidly spreading (and undesired) plant may be called invasive regardless of its place of origin, and it is one of my biggest pet peeves and a huge hindrance to getting reliable information. I guess I’ll have to look further into the scientific definition of invasive because this video has decreased my confidence in my understanding of the term.

    22:35 there is honeysuckle, and then there is Japanese honeysuckle. The image shown in the segment is Lonicera, which is a native North American plant. The honeysuckle most consider invasive is the Japanese honeysuckle. It is one of the few plants, like Ailanthus altissima (that is NOT a heavenly tree in North America), that are on my YOU WILL NOT PASS list. Multiflora Rosa is another. Those are really the three worst in terms of aggressive invasive plants around me. There are others, but those are the most problematic, and as this video clearly shows, there is only so much to be done. Trying to reduce the effects of the worst bad actors is the most practical course.

    Another example... The Broadleaf Plaintain (Plantago major) is a little, low-growing plant introduced from Europe. It is condered to be a pesky weed in North America. However, it has has been discovered that the caterpillars of the endangered Taylor's Checkerspot Butterfly (Euphydryas editha taylori) readily eat, grow, and thrive on this weed. Which is good, because some of the native plants the Butterflies once relied on aren't doing so well either.

      @@kaceesavage Cutting it down before it seeds, can stop it, but it takes years. And you must take a lot of precautions, goggles, facemasks, those disposible white overalls, covers for your footwear and long gloves. Be careful to clean the tools (your weed wacker) and any surface that they touch, because the sap can spread. Some people use plastic for the plants to fall on and wrap the plants to dispose them. Some people burn them but read up on it, as I have heard the smoke can be very irritating. We have a lot of here in Ontario Canada.

    Horses aren't an invasive species because they were they native, went locally extinct and were then reintroduced which is probably why they didn't have a negative effect on the environment and I bet there were other positives not mentioned in this video, it's similar to when wolves were reintroduced to Yellow Stone and greatly improved the area

    I live in the NW and am looking into raising sheep. I expressed to the person I am getting seeds for the pasture from that I wanted a seed bag without invasive species, but he insisted that there were some that we should have, but that it could be done in an environmental way. I had him explain, and among other things, it turns out some non-native species mixed in with the native ones means that the native plants won't risk being overrun by invasive species outside our property, helps to maintain soil composition, and that the invasive grasses chosen are chosen because they do not spread easily and are at a low risk of propagating outside our fields. Some of them are even modified so that they don't seed at all, while the native grasses are kept unmodified.

      The concept that many "biological purists" forget is that species migrated without human assistance for eons. I have heard prairie specialists say that they wouldn't plant grasses from another part of the state because it would mess with the local gene pool. This is in a state where 95% of the terrain has been turned to monoculture farmland. Seeds from prairie plants traveled hundreds, if not thousands, of miles in the coats and digestive tracts of birds and roaming herds of herbivores for thousands of years.

    I wish a bigger emphasis was put on how invasive cats are, they're the world's #1 invasive species. They've done far more damage than any species on this list and we have people here trying to protect them instead of the native wildlife. They hunt anything that smaller than them. Each cat kills hundreds of amphibians, birds, insects, and lizards every year and that affects so many aspects of our environment, even the owned and fed outdoor cats hunt like this. Wherever there's several outdoor cats there's a huge spike in fleas, neighborhoods are infested with them and we have to resort to pesticides to keep that in check. We need a government program to intervene and harsher fines for people that release and support outdoor cats + education on the matter so people stop getting upset over the idea of controlling the population. Catch neuter release is proven to be non-effective. Toxoplasmosis is rampant because cat poo is everywhere. Keeping cats outdoors is also very dangerous for the cat. I get why people want to protect them but we all need to look at the big picture and videos like this need to talk about it more even if it's controversial. Rant over.
