      Logarithmically scaled image. I’ll leave the determination of the base of the Log as an exercise for the viewer.

        That’s what I thought, so I investigated.

        The base of the log can be accounted for by a constant scale factor, because, for example, if n is the number of bison,

        log10(n)
        = log10(e^ln(n))
        = ln(n) log10(e) and log10(e) is a constant.
        This change of base is a linear scale on the logs.

        Hence we can just take log 10 of the numbers of bison, and scale the answer by a constant factor which is log10(correct base), getting
        7.778, 2.477 and 4.477
        Scale that by about 2 = log10(100) to match the 5 bison in the middle pictogram, and there should be
        16, 5, 9 bison on a logarithmic scale.

        The diagram is also wrong if it’s logarithmic.

    The decision to stop was required, but a ton of work was done to help the population rebound. What kind of misguided message is this trying to send?

    Each buffalo in the first picture represents 242,914 buffalo. Which means the last picture would be about 1/10th of a bison, and the middle one would be just the tip of a horn.

    TIL There are 30,000 free roaming bison but there are 500,000 total including privately owned and commercial herds.

    So I’m not bothered by the inconsistent scale… but why is there a dinosaur peeking through the bottom of the 1889 column?!

    Not perfect recovery, but still a powerful reminder that “too late” isn’t always true. Stopping the damage is step one.

    The white man had to kill the buffalo so that he could poop upon the land instead. We need our buffalo back in this land.
