So many aspects of natural history are ignored, that "everyplace" is effectively unknown. Environmental change makes everything different than it was before, and requires re-exploration of every territory. As we learn more, more detail and complexity unfolds to us. Henry David Thoreau 'travelled a good deal in Concord,' providing an unparalleled public record of the species he recognized and their relationships in natural communities, and making major advances in theoretical ecology simply by constantly re-exploring his ancestral ground.

Anyone can do for their home range what Thoreau did for Concord: notice, record, monitor, analyse, and publicize natural phenomena. Every one who goes out as a serious observer, with a field notebook or journal, is adding to our understanding of nature.
