What are the impacts on the SGM caused by humans?
This is a rather broad question, and anyone who knows of other impacts should email me to make these answers better and more complete. My answer below is not the product of research, but is “off the top of my head”. The SGM is one of the more untouched environments in the U.S., which is not to say that it is pristine. Probably the largest effect on the SGM now is the existence of roads. Roads kill a large number of animals (birds, snakes, squirrels, etc.) on a daily basis who are simply trying to cross the road. Further, the construction of roads can sometimes disturb natural paths to water, safety, etc., and hence can change the entire ecology. The next largest impact is probably the introduction of non-native species, both plants and animals. There are numerous stories of how the introduction of non-native species can wipe out a number of native species that depend on each other. I don’t know of the specific ones causing problems in the SGM, and would appreciate feedback from those t
