How “invasive species” are *forever* (it seems) invasive?

746 viewsBiologyOther

My thought process is that, after enough time, an invasive species of some plant or animal would find its way into its new ecosystem, and properly become a part of the ecological cycle? Does this ever happen? Maybe it just needs far more time to do so?

Think about it this way — in about 100,000 years almost all traces of above ground human infrastructure will be gone, but many of the species we imported will still remain. The example I always think of is Japanese knotweed in many parts of the east coast — this plant will surely be around in places it’s not native to long after humanity is gone. In that way, it will always be “invasive”.
