Birds and bugs have evolved over eons to adapt to the native plants they eat and nest in. And that’s what they need to survive. The monarch butterfly larva eats milkweed. That’s it. If there are no milkweeds, there will be no monarch butterflies or any of the other 11 species that specialize in milkweeds. Beautiful and fascinating plants, milkweeds’ lovely flowers turn into extraordinary seed pods. Once opened, thousands of silky threads float their attached seeds through the air. But milkweeds are not conventionally pretty. They’re a little wild looking. Those silky seed threads could land in the lawn! You would be hard pressed to find milkweeds in a nursery selling plants to the general public.
Over 5000 non-native plant species have taken over vast swathes of our natural world. It’s such a mess that in many places the only way to preserve the natural ecosystem is to first reclaim it. Eastern deciduous forests are being smothered by bittersweet and mile-a-minute vines. Autumn olive is choking Utah’s great river canyons. Wetlands are disappearing under the seductively pretty haze of lythrum’s magenta flowers. Some plants, like the melaleuca that is destroying Florida’s Everglades, were brought here to do what they did. Developers wanted to drain the swamp to contain mosquitos and allow building. A few invaders arrived by accident. Others, like the oats and annual grasses that have taken over the hills of California, were grown for fodder. The eucalyptus and pampas grass spreading along the west coast were among many, many plants brought here as novel ornamentals.
Possible answers bring us back to the stories we tell ourselves. The dream of the west, and now most of the world, has been dominion. The earth is ours to subdue. Humans, or at least a select subset of them, are the undisputed lords of creation. Other humans, animals, plants, minerals all exist for the benefit of those with money and power. This is the driving force behind the destruction of the Amazon rainforest today. A milder but still deadly version drives the landscaping trade. New and more exotic plants, more lethal insecticides, billions spent on millions of acres of grass two inches high.
