Well it really depends on where you conducted your fieldwork, if you did any...factors that effect the wetlands consist of things like:
# the flow of water going in and out of the ecosystem
# the interuptions that any new species introductions to the food chain have made on the ecosystem, etc.
By the way, i havent started studying for the exam yet so i may be a little rusty...oh well its still how many days away...
