A lot of thought in permaculture comes from the idea of asking why a species shows up. For instance: grasshoppers show up when plants start to yellow and die off. As the plant changes physically it’s also changing chemically. It’s releasing information to the grasshopper that it would be a good source of food. It triggers a cycle of life.
I often wonder why some of these species (autumn olive for example) show up and why they are listed as invasive. I believe AO is a nitrogen fixer. If the soil already has that then the AO wouldn’t have a role and probably wouldn’t grow as well.
Water hyacinths can be used as a high protein feed to animals. I think it’s time to start looking at our problems and diagnosing root causes as well as what solutions they could be solving, especially in nature. Idk how a species can be invasive, they are all natural to earth as far as I can tell.
