Tennessee is home to approximately 180 mussel species, 90 species of crayfish, almost 200 species of snails, and 320 freshwater fish (Meyer, 2016). Around 2,880 plant species have been documented in Tennessee according to the Tennessee Flora Committee (2015). When it comes to development, on both a state and federal level there are procedures in place to protect rare species. How do they work?
Much of what we build has an impact on the environment, from the highways we drive to the homes in which we live. Where do these impacts occur? To what extent do they impact the environment? GIS is an essential tool that allows us to investigate the extent of our environmental impacts. If you are interested in learning the software, we have several resources for you.

But if you are at all versed in scientific literature, you are well aware that we are losing our wetlands.
