Answer
I am an ecologist but am unaware of a "greenfield" ecosystem.  Are we talking about a grassland?  In any case you will ahve to find out what types of organisms inhabit in the area and then establish the food webs.  Look in a text for a grassland or prarie biome and find out about proucers and 1st, 2nd and 3rd order consumers
