Know your agroecosystem
The first step to knowing your agroecosystem is knowing your broader ecosystem region. Above is a map of the ecological regions of the US as designated by EPA in the early 90s. Of course you can be a splitter or a lumper and make more or fewer of these regions as you wish. But do try to explore this map a little and see why these regions make sense or not.
Once you have a handle on the natural ecosystem, you are ready to tackle the managed ecosystem. An agroecosystem can be defined as a management strategy applied to a natural ecosystem.
Compare the NRCS map of cultivated lands in U.S. (below) to the EPA map (above) to get a first idea of U.S. agroecosystems.
Nearly every state has resources in agroecosystems.
A few are listed below. If you know of others, tell us and we’ll put them up.
