Researchers warn against decline in carnivores

The researchers have expressed concern over the decline in the population of carnivores saying that it will seriously damage our ecosystems. The researchers have called for a global initiative to conserve these predators for the sake of our ecosystem.

An Oregon State University report says, more than 75 percent of the 31 large-carnivore species are declining. This is altering the face of landscapes worldwide.

They conducted study of 31 carnivore species that revealed how threats like persecution by humans, habitat loss and loss of prey are leading carnivore decline.


Southeast Asia and the Amazon are among the prominent areas that are witnessing decline in the carnivore species.

“Globally, we are losing our large carnivores.Their ranges are collapsing. Many of these animals are at risk of extinction, either locally or globally. And, ironically, they are vanishing just as we are learning about their important ecological effects,” said lead author William Ripple, a professor in the Department of Forest Ecosystems and Society at Oregon State University, in a statement.

The experts have identified seven species that have been examined for their widespread ecological effects: African lions, leopards, Eurasian lynx, cougars, gray wolves, sea otters and dingoes.

The  findings of the study are published in the journal Science.

    Suitably they’ve chosen a picture of Old Boy, a lion who liked to pose for tourists in the Etosha National Park. Beautiful, wasn’t he. He was shot and killed by a hunter shortly after that picture was taken.

    I’m kind of curious what 25% of large predators are NOT declining, I don’t know of any large predators which are not being displaced or killed.

      Coyotes, bears and cougars steadily increasing in SE US.

      Just so you know…

      As to Old Boy — why would you want him to die of old age? Did you secretly hate him? Sounds like he was given a good death, to me…

        You are seriously ill.

    It saddens me to think that such a regal creature will be lost. People just don’t get that everything is connected. We just keep killing everything off and we just keep reproducing. Hopefully, I won’t be around to see the extinction of the lion, wolf, leopard, dingo, lynx or any other great predator.

    • Pondo

      It saddens me to think that everyone thinks we can live in Eden without consequences. City dwellers watch Discovery channel and feel warm and fuzzy seeing footage of these “regal creatures” but do not fully understand the damage to other wildlife, cattle ranches etc. As far as cougars go, a decline? I KNOW THAT’S NOT THE CASE!! The cougar population has almost tripled in the past four years! Bringing Oregon to historic population densities! Our Elk and deer populations are in decline! GET YOUR RESEARCH RIGHT!! THINK BEFORE YOU PUBLISH SUCH RUBISH!

        Not everyone who understands the effects of the loss of large predators lives in cities. We are on a working ranch, and have had losses from predators. Just because one predator is gaining ground in one area doesn’t mean all are. I don’t want to see them gone, I want my grandkids to be able to see a lion in Africa or a tiger in India if they desire. And the implications of the loss of the world’s predators is vastly greater just the fraction of trouble some cause. I was devastated when my sheep were attacked, and lost 2/3 of my flock, but I got guardian dogs and haven’t lost a sheep in 4 years now. And frankly, I am danged tired of a bunch of yeehaws speaking for the ranching industry, we don’t all want to kill everything that eats a calf or sheep, some of us just want to co-exist and protect our stock.

        • Pondo

          Well spoken sir! I completely agree with you. I do not want you to think I speak for anyone other than myself. I do not think these majestic creatures to be eradicated, but maintained at resonable at reasonable populations. Since man has encroached on their territory, we must coexist. I have had numerous encounters with cougar and bear, nothing has been more awe inspiring! I want my children to see and experience the same. Extremists on either side of the fence will push for an agenda that fulfills their special interests. Although the original author didn’t say this ,We can’t keep putting animals on the endagered species list if we intend to coexist. Semper Fidelis

          • John T

            Yes, there does need to be a good analysis and management of the need for predators. One famous example is the Kaibab Plateau in the 1920’s. All of the large predators were hunted down with the thought of protecting the deer. The result was that the deer multiplied, consuming all the forage, with the result of many dying of starvation.

          I am betting that your ranch is supported by outside income — nothing wrong with that, just saying…

          Also betting that you do not grow watermelons, and you have neighbors who are controlling coyotes…

          Again, just saying.

          • texomamorganlady

            The ranch is on it’s way to becoming self supporting, only partially now. No melons, my neighbors make use of guardian animals, donkeys, dogs, llamas, etc. We do shoot and trap wild pigs as often as possible though. Hogs are non native and kill out ground dwelling birds and ruin acres of crops.

          • xzx

            Sounds good, I’ll be pulling for you.

            The hogs will eat all your snakes as well — on the plus side, I am pretty sure they put a hurt on rodents, too.

            Oddly, hog caused crop damage has not been an issue for me, and I have no idea why.

            For myself, I like having a few around, although they attract criminals…

          • Kurtis Engle

            Hogs are not endangered. On the contrary, they are vermin. Non-native,
            very dangerous and they tear up crops. And they are off topic.

        • Kurtis Engle

          And buy insurance.

      • KENSAI

        maybe in your area- the article was talkling, globally..not just in Oregon…maybe in Oregon you have one of the larger deposits of these animals on the globe. In other places where they normally call home- they are disappearing-get YOUR RESEARCH RIGHT!! Think before you publish such rubbish!!

      • grassroot

        Cougars, Mountain Lions, Panthers, Painters,
        etc. are all on the increase. Plus, wolves.

        • texomamorganlady

          We definitely need to control those painters, they eat a lot of stock animals, lol

      • Wilf Tarquin

        I checked, and Oregon does have a healthy cougar population. It is however shrinking, due to increased hunting after changes to your local laws — your current administration interprets the requirement to maintain at least 3000 cougars in the state as a requirement to keep _exactly_ 3000 cougars in the state, and have loosened rules and made tags cheaper.
        Also, compared to pre-european times this is a low number, but it is higher than the 1980’s low-point, at which thee were only 200.

        As for your deer, the reason for the drop in numbers is alleged to be a combination of loss of habitat and disease. That said, they’re still not exactly rare: hunters kill 190 000 deer/year in Oregon.

      • Kurtis Engle

        Well, we have heard from the “Ranchers”. Now let’s hear from the wildlife biologists.

  • Jeffrey Nelson

    We are the most aggressive destructive predator on the Earth because we are destroying the fragile environment by using up resources and exploitation of planetary ecological survivals. Eventually, our homo-sapiens will end of the existence in a near future. We will become another dinosaurs, which they once were dominated species roaming on the Earth for several millions years. Read the book: Overshoot: The Ecological Basis of Revolutionary Change ~ William R. Catton

    • xzx

      You read that book while I save the ecosystem by eatind some wildly overpopulating hetbivores.

      • Kurtis Engle

        Thank you for doing what you can.

        Probably should learn to read, though. Lot of good ideas in books.

  • D Green

    we are truly pitiful- a species who demise is unadvoidable

  • gacl

    As long as the human population is growing so rapidly, human encroachment on animal habitat seems quite inevitable. How many times can we double our population and still leave ample room for large animals?

  • fixento

    They fail to mention coyotes are multiplying like rabbits as are wild pigs in the US. Both can be shot anytime in some states. Coyotes won’t attack wild pigs because they travel in droves but do attack domesticated animals.
    Lets give carnivores a hand, deposit at least one in every PETA meeting.

  • Blair Williams

    Let Cisco fix it or one of the other tech giants. They seem to think their technology is going to cure all things and connect all things. We lose this and we lose our souls and the ambitions of men and technology are at the root of all of this as it is all connected.
