Bad bit, invasive species are incredibly damaging to local ecosystems oftentimes causing mass die offs, if not extinctions, of local flora and fauna. See round gobies, Asian carp, and zebra mussels in the great lakes. More often than not invasive species are introduced accidentally into ecosystems by humans, they are not naturally migrating there.
We do see migrations of animals further north as the climate warms like armadillos and deer ticks in the Americas but these are not treated as invasive species. Similarly, species not native to an ecosystem but have become naturalized and are therefore not as damaging are not treated as invasive, like European starlings, dandelions, and pigeons in North America.
Now from a Vegan POV 
I don't know what the best solution to invasive species would be. I have heard some vegans make the argument that invasive species control is better as it results in less animal death overall but it is difficult.
I am receiving reports that the Trans Mega has ties to Shadow Inc. And is obfuscating the primary results
