At times during the debate around invasive species, it’s the absurd that strikes the strongest chord. Prevention is a reasonable approach. Eradication after full-scale establishment seems like folly. Evolutionarily, it’s a whole system problem. Take the example invasive Fire Ants that originated in Brazil. Real, potential solutions appear to be phorid flies that lay their eggs inside the ant’s head and fungi that are natural predators/parasites of the ant. Go back to source, investigate complex ecologies for solutions. Most recently humans have been a major cause of jump dispersal, another name for invasive species. But hasn’t much of evolution been the product of “invasive/exotic” species from the very beginning? So if we bring on the cats, then don’t we need more dogs?
