they take them and they plant them and something lost between.

they are killing off the non-natives and they are planting the natives. they are taking the gnarled and lovely old soul trees that resonate with time and character and magic away. they are addicted to oil and overweening control of the garden and of the behavior of the denizens of the garden. they will continue outside the garden to destroy species at a rate no longer even remarked or alarming. they will genetically invent new species that do not procreate and are listed as pesticides. they will make the garden without anarchy or love and you will want to die for freedom then when it is too late.
