Natural Blow Job
Like an endless army of parachutists released from an airplane, seeds and fruits travel the wind currents and gentle breezes of the earth, possibly colonizing a distant mountain slope or fertile valley potentially 1000 miles from their origin. Literally hundreds of species in many plant families have adopted this remarkable method of dispersal and make the promoters of native plants look like a fool.
Imagine a little parachutist seed can fly 1000 miles in ten days it still takes probably 20-30 generations and 15-20 years getting around the globe. Seeds found in hail or high altitude air samples confirm that this is not a fiction.
Plants have very limited mobility and consequently rely upon a variety of dispersal vectors. Wind is only one and there are many other smart ways. The easiest might be humans. If a plant gives humans a trade-off (nice flower, fruit etc.) they can carry them as far and nowadays in a much short time.
Relocating to a faraway location isn’t always successful but it is necessary for the specie to survive in evolution where natural and manmade forces might eliminate the original place. Especially under fast changing climate conditions it is important for specie to stay flexible or to mix with similar species to create more resident ones.
Comparing to this smart and self-sustaining way of plants, many humans make themselves to fool by either helping to transport the plants or by categorizing plants into native and non-native. Doesn’t it sound like schizophrenia when you get a LEED point for native plants on a 500sf Green Roof downtown Manhattan and at the same time(GMO) corn is grown on almost 100,000,000 acres across the US?
There is no question that the worlds Gen-pool of all organisms must be preserved but the way as it is approached seems in most cases unprofessional and desperate. Being 45 years a gardener, I understand that nature has its own way – we can be part of it but we can’t be the director of it.
