  1. they are still beautiful, I have tons in my woods next to me and in my pastures which I usually mow down, crown vetch is all over the hills of pennsylavian when I used to go through there on a bus, the daisy is beautiful, I am thinking that maybe it is best we learn to love them just like the natives species because frankly to rid the usa of these invasives would not only be expensive but futile, these still provide food and shelter and if you don’t tell anyone they are not native no one would even notice. does it matter whether a food producer is native or not? after all life never stays the same and many of our natives may have crowded out other plants in times past that were native which means hte native was actually the invasive

    • Roberta, many of these non-native plants are capable of producing monocultures in areas, or can significantly reduce biodiversity. Although many of these plants still produce edible fruits/seeds to local wildlife, if the area only contains that single species, that food source is only available for a short period.

      It gets even more complicated when you start looking at insect populations. Many insects are only able to feed on 1-3 plants. Often these invasives are not eaten by any insects. That is why they are promoted for ornamental trade. Food webs can be complicated and the introduction of new species, or extirpation of native species can have far reaching consequences.

      Eradication of many of the species I show on this blog is not possible, but most all of these species have not expanded to all the possible areas and niches that they could. There is still time to prevent the further spread of many of the species in to non-infested areas, and at least at a minimum stop maintaining them or continuing to planting them.

      Although many species have migrated around at times through natural means (look up cattle egrets for a great modern day introduction), our global economy facilitates the whole sale exchange of species in the world at a cost to global biodiversity. Simpler systems have less resistance and resiliency to perturbations, which can a lot of issues not only for natural systems, but humans also.

      It is easy to get beaten down when learning about invasive organisms, but there is still a lot of things we can do to help control and prevent invasives. I hope you keep visiting to learn more about the ecological impacts of invasive plants and find ways that you can help out. I hope an answered some of your questions!
